* perf(import-target): index the workspace once per run for go/csharp/dart/ruby Four import-target resolvers answered their lookups with a full `allFilePaths` scan per import, making resolution O(imports x files): - go (#2877): `findRootPackageFiles` / `findAllFilesInPkgDir`, the latter once per path segment on the GOPATH fallback. Most Go imports are external, so the whole cascade ran to completion before returning null. - csharp (#2878): the no-csproj leg took the raw Set past the memoized index the csproj leg was already using - up to eight passes for a four-segment `using`. - dart (#2879): one scan per candidate path, and for an external package both candidates miss, so both always ran to completion. - ruby (#2880): a complete `buildSuffixIndex` rebuilt and discarded per `require` - every require paid to index every file in the repo. Each now reads an index memoized on the `allFilePaths` Set identity, the shape `getPythonFileIndex` (#1918) and csharp's own `getWorkspaceFileIndex` (#1881) already used. Two shared modules back them: - `workspace-file-index.ts`: normalized list + `SuffixIndex` + a normalized->raw map, for csharp and ruby. - `package-dir-index.ts`: "which files live directly inside a directory ending with <path>", for go and csharp. Candidates are bucketed by the directory's last segment rather than by indexing every directory suffix, which would cost O(files x depth) entries at kernel scale (#2649). Behaviour is unchanged, including the tie-breaks that are expressed only through Set-iteration order and `indexOf` positions: the go root leg stays sorted and its package leg stays unsorted, the first-occurrence rule that excludes a directory nested inside a same-named directory is preserved, csharp's whole-path match still beats an earlier suffix match, and dart still tries `lib/<rel>` fully before bare `<rel>` and matches raw paths. Verified two ways. `import-target-index-parity.test.ts` keeps verbatim copies of the pre-change implementations and diffs against them over a deterministic corpus plus hand-built layouts for each tie-break; six mutations of the new code were confirmed to fail it. Separately, the bench corpus produces byte-identical fingerprints against the pre-change resolvers at both 400 and 1600 files. `bench/import-target/measure.mjs` gates both arms in CI: per-language output fingerprints, a scaling budget (measured 0.98-1.12 here, 3.32-4.10 against the pre-change scans), and the corpus shape, so the corpus cannot be shrunk below the size the scaling arm needs and still print PASS.

Fold it into the shared measures so all five resolvers are gated on one corpus, and adopt the two arms that PR's review proved a scaling ratio alone cannot carry. - `bench/import-target/measure.mjs` gains a kotlin arm: a Gradle-shaped corpus with per-module source roots over one package namespace, `.kt` and `.kts` stems, a nested same-name package directory, and a share of wildcard `.*` imports so the package fan-out tier — the only tier whose output is order-bearing — is inside the fingerprint. - `depth_ratio`: deep arm at a FIXED file count with ~6x the path components. `scaling_ratio` divides the file count out, so it is scale-invariant and structurally cannot see a cost that grows with path depth instead, and `buildSuffixIndex` (C#, Ruby) and Kotlin's `suffixByStem` each emit one entry per component. Measured: go 0.98, dart 0.88 (depth-free indexes), ruby 1.48, kotlin 2.20, csharp 3.45 — which is why the budget is per language. One global budget would have to sit at 5.0 and would let Dart go 0.88 -> 4.9 unnoticed. - `small_ms_ceiling`: an absolute bound at 4x the measured arm, because a constant-factor regression that grows both scale arms equally passes every ratio. - The deep arm must resolve exactly what the small arm resolves. Padding was supposed to change depth and nothing else; a deep arm that stopped resolving would be timing the null path. The five fingerprints are unchanged by this commit - verified against the previous baseline before rewriting it, so adding the kotlin arm and the deep scale did not perturb the four languages' output. Kotlin joins the Set-iteration counter in `import-target-index-parity.test.ts` too. Its own guard (`kotlin-import-index-reuse.test.ts`) counts index BUILDS, which a scan added beside a reused index does not move. That counter is also the only DETERMINISTIC guard against a reintroduced scan, and this commit documents why rather than pretending otherwise: a full workspace scan on 1-in-32 imports was measured to pass every timing arm here (dart, 1.458 scaling against a 1.8 budget, 1.736 ms against a 4 ms ceiling) while the counter reads 14 instead of 1. Tightening the ceilings toward the noise floor to chase that case would only buy flaky CI. `bench/kotlin-import-target/` stays: it fingerprints both file-set iteration orders and probes the four-tier cascade shape by shape, neither of which this corpus does.

On a Go monorepo where many services carry the same package directory (`svcN/internal/pkg`, which Go's GOPATH cascade queries by two-segment tail) that made the index SLOWER than the scan it replaced: 13.4x at 1600 matching directories. Append into one array and sort once. Measured against a verbatim copy of the pre-change scan, output byte-identical at every k: k=200 1400 files old 0.126 ms was 0.169 ms now 0.042 ms k=800 5600 files old 0.457 ms was 3.002 ms now 0.185 ms k=1600 11200 files old 0.960 ms was 12.890 ms now 0.232 ms The index now beats the scan by 2.5-4.1x on this shape instead of losing to it by up to 13x. Also drop the min-`ord` comparison in `firstFileDirectlyInPkgDir`: the build loop appends a directory to its last-segment bucket the moment it accepts that directory's first file, so bucket order already IS ascending first-file-`ord` order and the first hit is the minimum. Differentially verified at 0 divergences. The invariant, and the build-loop edits that would silently break it, are now recorded at the early return. Type the index containers as deeply readonly so Go's deliberate `[...rootFiles].sort()` copy is compile-enforced rather than comment-enforced, and correct the header's claim that a polyglot repo "never pays" -- only the stored index is per-language. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_013rLy781K8E3rRHFGEe1khJ * test(import-target): guard index reuse at the adapter boundary `workspace-file-index.ts` documented the hazard as "a defensive `new Set(allFilePaths)` in an ADAPTER" -- the bug #1918 shipped -- and named the unit parity test as the guard. It is not: that test imports the resolvers directly, while production reaches them through `<lang>ScopeResolver.resolveImportTarget`. Inserting the copy at `go/scope-resolver.ts:31`, `csharp:35`, `dart:189` and `ruby:268` left the parity test 28/28 green and `measure.mjs --check` PASS in all four cases. Kotlin and Python already had adapter-level guards; go/csharp/dart/ruby had none. Add `test/integration/<lang>-import-index-reuse.test.ts` for the four, mirroring the Kotlin/Python precedent: resolve through the scope resolver, assert the file set is traversed once (twice for C#, which builds two indexes), and pair every count with a result assertion so a count of 1 cannot be the count of an adapter that resolves nothing. Each was proven to fail under the copy it exists to catch: go expected 600 to be 1 dart expected 600 to be 1 ruby expected 400 to be 1 csharp expected 600 to be 2 `CountingSet` moves to `test/helpers/counting-file-set.ts` and now counts `forEach`, `values`, `keys` and `entries` as well as `[Symbol.iterator]`. It missed a rescan spelled `allFilePaths.forEach(...)` entirely; with the overrides that mutation reads 14 instead of 1. Four fixtures that pinned the guard next door, each now shown to kill its mutation: - the Dart "matched RAW" case used a forward-slash target, so the basename bucket missed before the raw comparison was reached and it asserted `null === null`. A positive twin carrying the backslash in the TARGET catches both half-mutations. - no C# or Ruby target addressed the corpus's `win\dir\thing` file, so deleting the backslash normalization in `workspace-file-index.ts` passed both gates. Now 4 failures. - `normToRaw`'s first-wins rule had no normalization twin in any corpus. - the Go nested-package fixture was decided by the `endsWith` half and never reached the first-occurrence branch its title names; addressing the directory as a single segment makes it reach it. The parity test's own docstring no longer claims the scan count is a complete census -- it names the three materialized arrays it cannot see. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_013rLy781K8E3rRHFGEe1khJ * test(import-target): assert every scale, add collide and retained-heap arms Three holes in the gate this PR ships as its own proof. 1. `--check` computed three fingerprints per language, stored all three, and compared one. `DEEP_PAD = 16 -> 0` deleted the entire depth arm and still printed PASS, because depth padding is count-neutral by design so no asserted number moved. Assert `fingerprint` per scale, and assert `deep.fingerprint !== small.fingerprint` so the padding's EFFECT is pinned, not just its output. 2. The corpus minted per-index directory names (`src/pkg${d}`, `src/Ns${d}`, `lib/feature${d}`), so max last-segment bucket and max matching dirs were both 1 -- and bucket cardinality is the only non-constant term the index has. The `dirCount > 1` merge branch had never executed in any arm. Add a `collide` arm on shared-leaf layouts with identical files/imports/resolved counts; it reaches 9,269 multi-directory merges per run, up to 34 directories at once. Go and C#/Dart legitimately score above the linear budget there and get their own; Ruby and Kotlin stay at 1.8 because their keyed maps are collision-immune and that immunity is the assertion. 3. No arm measured memory, while the C# no-csproj leg newly retains an O(files x depth) suffix index. Add a retained-heap arm on the `bench/cfg` pattern, including its loud failure when `--expose-gc` is missing rather than a silent skip. Measured at 32k files: csharp 73.62 MiB, ruby 55.26 MiB. Ceiling is 1.5x, NOT the 4x the timing arms use -- the measurement is byte-stable to 0.00085% across processes, so 4x would be throwing away the gate. `_arms_note` records why, so nobody harmonises it back. `depth_ratio`, added by this PR, flaked ~1-in-20: go peaked at 1.748 and dart at 2.043 against a 1.6 budget, both ratios of two sub-3 ms minima. Fixed at the estimator, not the threshold -- REPS 5 -> 15, matching `bench/cfg`, `schema-pairs` and `callable-value-flow` (5 was the lowest in the repo; the sibling `kotlin-import-target` uses 7, which was not enough here). 22/22 PASS, every arm now at 70-78% of its budget with a <=1.26x swing. No budget was widened; the distributions are recorded in `_arms_note` so the headroom is visibly earned. Three copies of the same overclaim corrected: the parity test NARROWS the 1-in-32 blind spot, it does not close it -- it watches the Set while the resolvers hold materialized arrays. `_floor` no longer claims its ratios "match" the issues' (different corpora, both quadratic). The step moves to the END of the benchmarks job and runs with `--expose-gc`. A failing step aborts every step after it (#2895), so the newest, least-proven gate must not sit ahead of eight established ones. All five output fingerprints are byte-identical to before this session -- the proof that every change here was behaviour-preserving.

It does not -- it never crosses the adapter. Name both layers and say which catches what: the per-language `test/integration/<lang>-import-index-reuse.test.ts` files at the adapter boundary, the parity test for a rescan reintroduced inside a resolver. The C# namespace-dir index comment named `findDirectChild`, which this PR deleted; it feeds `firstFileDirectlyInPkgDir` now. Drop `GoResolveContext`, dead since the legacy call-resolution DAG was removed in #942 -- zero importers, and `gitnexus`'s package.json declares no `main`, `exports` or `types`, so it is not a published surface. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_013rLy781K8E3rRHFGEe1khJ * refactor(import-target): quality pass over the review-round changes Four cleanup lanes (reuse / simplification / efficiency / altitude) over the previous four commits. No behaviour change anywhere: all 25 bench cells (5 languages x 5 arms) are byte-identical on files, imports, resolved, distinct_outcomes and fingerprint, re-verified after each individual edit. **Restores a fast path the last commit lost.** Fixing the O(k^2) accumulator made the SINGLE-directory case — the overwhelmingly common one — copy the bucket where the original aliased it: measured 1.11x slower at 4 files/dir rising to 1.72x at 128. Holding the first bucket by reference and promoting to an accumulator only when a second directory appears is 0.65-0.97x of the previous code at dirCount=1 and parity at dirCount=64. 176-case differential, 0 divergences. **`sortedRootFiles` accessor.** `rootFiles` was the only index container read directly from outside the module. `readonly` is erased at runtime and `Array.isArray` widens it back, so the copy rule now lives with the code that owns the invariant instead of at the call site. No `Object.freeze`: V8's PACKED_FROZEN_ELEMENTS read cost lands on the hot `matchingDirs` path. **One shared arm for the four reuse guards.** The distinct-file-set test was copy-pasted four ways, 33-38 identical lines each, and this repo's own helpers (`mini-repo.ts`, `scope-model.ts`) document extracting at the SECOND verbatim consumer. `expectDistinctFileSetsGetOwnIndex` takes what actually varies; its `expected` type excludes `null` so the pairing rule cannot be reinstated as a hole. The per-language first and third arms stay duplicated on purpose — corpora and payload shapes genuinely differ. Re-proven: all four still fail under an adapter-inserted `new Set(allFilePaths)`. **Bench.** `dirsFor` shared by the two functions that must agree on directory fan-out (they mint and address the same files). `SCALES` derived from the arm table, so a future arm cannot be measured, printed and silently never asserted. Five timing checks with one shape collapsed to a table — the trailing sentence had already drifted into four wordings. `uniqueTarget`/`collideTarget` as flat functions, mirroring the `uniqueDir`/`collideDir` split rather than nesting a second axis four ternaries deep. One `identityPass` replaces two untimed full resolution passes per cell: -371 ms median. **CI step moved back where it belongs.** It was parked last "until #2895 lands", but that reasoning was backwards twice over: the flake that motivated it was fixed at the estimator in the previous commit, and #2895's own audit measured the last slot as executing zero times in 13 runs. It sits with the other resolver-index guards; #2899 carries the `if: !cancelled()` that fixes step masking for every step at once. Filed rather than fixed here: #2908 (java and cobol still scan the workspace per import, same shape as #2877-#2880, neither memoized), #2909 (make index reuse a contract test over SCOPE_RESOLVERS on one instrument).

The nervous system for agent context.
Indexes any codebase into a knowledge graph — every dependency, call chain, cluster, and execution flow — then exposes it through smart MCP tools so AI agents never miss code.
💬 Discord · 🌐 Web UI · 🏢 Enterprise (SaaS & self-hosted)
https://github.com/user-attachments/assets/172685ba-8e54-4ea7-9ad1-e31a3398da72
Like DeepWiki, but deeper. DeepWiki helps you understand code. GitNexus lets you analyze it — a knowledge graph tracks every relationship, not just descriptions.
TL;DR: The CLI + MCP makes your AI agent reliable — it gives Cursor, Claude Code, Antigravity, Codex, and friends a deep architectural view of your codebase so they stop missing dependencies, breaking call chains, and shipping blind edits. Even smaller models get full architectural clarity. The Web UI is a quick way to chat with any repo in the browser.
Quick Start
# 1. Index your repo (run from repo root)
npx gitnexus analyze
# 2. Connect your editors (one-time, auto-detects Claude Code, Cursor, Codex, …)
npx gitnexus setup
That's it. analyze indexes the codebase, installs agent skills, registers Claude Code hooks, and creates AGENTS.md / CLAUDE.md context files — all in one command. setup writes the MCP config so your AI agent can use the graph.
Install problems? npm 11 crash · slow cold install · no C++ toolchain
On npm 11.x?
npxcan crash during install withCannot destructure property 'package' of 'node.target'(an npm/arborist bug, before GitNexus runs). Use pnpm instead — it builds the native deps explicitly:pnpm --allow-build=@ladybugdb/core --allow-build=gitnexus --allow-build=tree-sitter dlx gitnexus@latest analyzeOr install globally (
npm install -g gitnexus@latest) and rungitnexus analyze. See #1939.
Fastest MCP startup: install globally (
npm i -g gitnexus) before runninggitnexus setup— this writes an absolute-path MCP config that bypassesnpxentirely. On a cold cache, annpx-based MCP install can exceed Claude Code'sMCP_TIMEOUTdefault (~30s).
No C++ toolchain? Set
GITNEXUS_SKIP_OPTIONAL_GRAMMARS=1beforenpm install -g gitnexusto skip the vendored grammar materialize/build fortree-sitter-dart,tree-sitter-proto,tree-sitter-swift, andtree-sitter-kotlin— those four languages won't be parsed, but install completes in seconds withoutpython3/make/g++. Strict=1only — any other value falls through to the rebuild.
Behind an HTTP proxy / regional firewall?
onnxruntime-node's postinstall downloads optional CUDA binaries fromapi.nuget.organd ignoresHTTP_PROXY/HTTPS_PROXY(#2370). The embedding stack is an optional dependency, so a failed download no longer breaks the install — and it self-heals: the firstgitnexus analyze --embeddings(orgitnexus embeddings install) fetches the stack through your npm registry config (mirrors/proxies apply, no NuGet) into~/.gitnexus/embedding-runtime(override withGITNEXUS_EMBEDDING_RUNTIME_DIR). The on-demand prefix needs Node withmodule.registerHooks(≥ 22.15 on 22.x, ≥ 23.5 on 23.x); on older Node, keep the stack in the install itself withONNXRUNTIME_NODE_INSTALL=skip npm install -g gitnexus(works on every supported Node).
About
tree-sitter-kotlin: like Dart/Proto/Swift, Kotlin is a vendored grammar (undergitnexus/vendor/tree-sitter-kotlin). Upstream ships source only (no prebuilt binaries), so GitNexus cross-builds the platform prebuilds itself (via thebuild-tree-sitter-prebuildsGitHub Actions workflow) and vendors them — the same uniform pipeline used for Dart, Proto, and Swift.node-gyp-buildselects the right.nodeat require time, so no C/C++ toolchain is needed. If no prebuild matches your platform-arch, only Kotlin (.kt/.kts) parsing is unavailable; the rest ofgitnexusis unaffected.
Deploy to Render
Deploy GitNexus in one click:
The Blueprint creates two services. gitnexus-server runs gitnexus serve as a private service: no public URL, reachable only over Render's private network, with a persistent disk for indexes and cloned repos. gitnexus-web is the public one. It serves the UI and reverse-proxies /api/* to the server, so the browser talks to a single origin.
At the Blueprint's defaults this runs about $35/month: $25 for the server's standard instance, $7 for the web service's starter instance, and $2.50 for the 10 GB disk. See Render's pricing for other plans.
The deploy generates an access token, and the UI asks for it on first use:
- Open the
gitnexus-webservice in your Render dashboard. - Copy
GITNEXUS_SERVE_AUTH_TOKENfrom its Environment tab. - Load the site and paste the token into the prompt (or the settings panel).
Every /api/* request carries that token as a header, and the proxy answers 401 without it. The browser keeps it in sessionStorage, so a new tab asks again. To rotate it, edit the environment variable and redeploy.
The proxy strips Origin before forwarding, so the server's CSRF guard does nothing for proxied traffic; it passes Origin-less requests through by design. The token is the only control on this deploy, not a second layer behind the guard. Anyone holding it can read every indexed repo. See SECURITY.md.
Indexing is memory-bound. If gitnexus-server runs out of memory on a large repo, raise its plan, which sets available RAM: standard is 2 GB, pro is 4 GB. Raise sizeGB only if the disk fills with clones and indexes.
Two Ways to Use GitNexus
| CLI + MCP (recommended) | Web UI | |
|---|---|---|
| What | Index repos locally, connect AI agents via MCP | Visual graph explorer + AI chat in browser |
| For | Daily development with Cursor, Claude Code, Antigravity, Codex, Windsurf, OpenCode | Quick exploration, demos, one-off analysis |
| Scale | Full repos, any size | Limited by browser memory (~5k files), or unlimited via backend mode |
| Install | npm install -g gitnexus |
No install — gitnexus.vercel.app |
| Storage | LadybugDB native (fast, persistent) | LadybugDB WASM (in-memory, per session) |
| Parsing | Tree-sitter native bindings | Tree-sitter WASM |
| Privacy | Everything local, no network | Everything in-browser, no server |
Bridge mode:
gitnexus serveconnects the two — the web UI auto-detects the local server and can browse all your CLI-indexed repos without re-uploading or re-indexing.
Why a Knowledge Graph?
Tools like Cursor, Claude Code, Codex, Cline, Roo Code, and Windsurf are powerful — but they don't truly know your codebase structure. So this happens:
- AI edits
UserService.validate() - Doesn't know 47 functions depend on its return type
- Breaking changes ship
Traditional Graph RAG gives the LLM raw graph edges and hopes it explores enough. GitNexus precomputes structure at index time — clustering, tracing, scoring — so tools return complete context in one call:

subgraph Traditional["Traditional Graph RAG"]
direction TB
U1["User: What depends on UserService?"]
U1 --> LLM1["LLM receives raw graph"]
LLM1 --> Q1["Query 1: Find callers"]

end
Core innovation: Precomputed Relational Intelligence
- Reliability — the LLM can't miss context; it's already in the tool response
- Token efficiency — no 10-query chains to understand one function
- Model democratization — smaller LLMs work because the tools do the heavy lifting

Repo-specific skills — run gitnexus analyze --skills and GitNexus detects the functional areas of your codebase (via Leiden community detection) and generates each one as a direct project skill under .claude/skills/gitnexus-area-<name>/. Each skill describes a module's key files, entry points, execution flows, and cross-area connections, and is regenerated on each --skills run to stay current.
When a repo contains an .agents/ directory, the standard and generated skills are also mirrored to .agents/skills/ (e.g. .agents/skills/gitnexus-cli/, .agents/skills/gitnexus-area-<name>/) so agents that read repo-local .agents/skills/ (like Codex) stay in sync.
Editor Setup
gitnexus setup auto-detects your editors and writes the correct global MCP config. Run it once. To configure only selected integrations, pass --coding-agent/-c with a comma-separated list, e.g. gitnexus setup -c cursor,codex.
| Editor | MCP | Skills | Hooks (auto-augment) | Support |
|---|---|---|---|---|
| Claude Code | Yes | Yes | Yes (PreToolUse + PostToolUse) | Full |
| Cursor | Yes | Yes | Yes (postToolUse, manual install) | Full |
| Antigravity (Google) | Yes | Yes | Yes (AfterTool, Gemini CLI hooks schema)¹ | Full |
| Codex | Yes | Yes | Yes (PreToolUse + PostToolUse, Codex hooks) | Full |
| OpenCode | Yes | Yes | — | MCP + Skills |
| CodeBuddy (Tencent) | Yes | Yes | — | MCP + Skills |
| Qoder (Alibaba) | Yes | Yes | — | MCP + Skills |
| Windsurf | Yes | — | — | MCP |
Claude Code and Codex get the deepest integration: MCP tools + agent skills + PreToolUse hooks that enrich searches with graph context + PostToolUse hooks that detect a stale index after commits and prompt the agent to reindex.
¹ Antigravity hooks follow the Gemini CLI hooks reference (Antigravity 2.0 is the documented successor to Gemini CLI). Augmentation runs in
AfterToolbecauseBeforeToolhas no context-injection channel in the Gemini contract — the agent sees graph context appended to the tool result viahookSpecificOutput.additionalContext. Stale-index hints land in the same channel after a successfulgit commit/merge/rebase/cherry-pick/pull. The schema may evolve if Antigravity-specific hook docs diverge from Gemini CLI's; the implementation will track those changes.
Manual MCP configuration (if you prefer not to run gitnexus setup)
Claude Code (full support — MCP + skills + hooks):
# macOS / Linux
claude mcp add gitnexus -- npx -y gitnexus@latest mcp
# Windows
claude mcp add gitnexus -- cmd /c npx -y gitnexus@latest mcp
Codex (full support — MCP + skills + hooks):
codex mcp add gitnexus -- npx -y gitnexus@latest mcp
Or via ~/.codex/config.toml (system scope) / .codex/config.toml (project scope):
[mcp_servers.gitnexus]
command = "npx"
args = ["-y", "gitnexus@latest", "mcp"]
Codex hooks (PreToolUse graph enrichment + PostToolUse stale-index detection in ~/.codex/hooks.json, same schema as Claude Code) need the bundled adapter script, so they are installed by gitnexus setup -c codex rather than manually.
Alternatively, install everything as a Codex plugin (MCP + skills + hooks in one step):
codex plugin marketplace add abhigyanpatwari/GitNexus
# then inside Codex: /plugins → install "GitNexus"
Codex notes: SessionStart is intentionally not registered — Codex reads AGENTS.md natively, which already carries the GitNexus context block. Newly installed hooks need a one-time approval in Codex via
/hooksbefore they run. Pick one install route (gitnexus setup -c codexor the plugin): plugin hooks load alongside~/.codex/hooks.json, so installing both can fire duplicate hooks per tool call.
Cursor (~/.cursor/mcp.json — global, works for all projects):
{
"mcpServers": {
"gitnexus": {
"command": "npx",
"args": ["-y", "gitnexus@latest", "mcp"]
}
}
}
Antigravity (Google) — ~/.gemini/antigravity/mcp_config.json:
{
"mcpServers": {
"gitnexus": {
"command": "npx",
"args": ["-y", "gitnexus@latest", "mcp"]
}
}
}
gitnexus setupalso merges anAfterToolentry into~/.gemini/settings.json(under the canonical Gemini CLI hooks schema) and installs skills to~/.gemini/antigravity/skills/. Existing user hooks are preserved. The hook adapter's path is rewritten at install time, so rungitnexus setuprather than hand-editing.
OpenCode (~/.config/opencode/config.json):
{
"mcp": {
"gitnexus": {
"type": "local",
"command": ["gitnexus", "mcp"]
}
}
}
CodeBuddy (Tencent) — priority chain, edit the first non-empty file that exists: ~/.codebuddy/.mcp.json (recommended) → ~/.codebuddy/mcp.json (deprecated) → ~/.codebuddy.json (legacy). CodeBuddy reads only the first existing file, so adding servers to a higher-priority file than the one currently in use would hide the servers below it. Create ~/.codebuddy/.mcp.json only if none exist:
{
"mcpServers": {
"gitnexus": {
"command": "npx",
"args": ["-y", "gitnexus@latest", "mcp"]
}
}
}
Qoder (Alibaba) — ~/.qoder.json:
{
"mcpServers": {
"gitnexus": {
"command": "npx",
"args": ["-y", "gitnexus@latest", "mcp"]
}
}
}
MCP read-only mode
Set GITNEXUS_MCP_READ_ONLY=1 before starting the MCP server to expose only the proven single-repository read surface. Raw cypher, rename and group tools, group routing, and group resources are omitted from discovery and rejected before backend dispatch. Tool descriptions and generated setup/context resources are scrubbed so they do not recommend unavailable routes.
The default is unchanged when the variable is unset or 0. Any other value fails server startup rather than silently weakening the policy.
MCP repository policy
Set GITNEXUS_MCP_ALLOWED_REPOS to a comma-separated list of canonical registry names or absolute indexed paths. Entries are trimmed, resolved against the registry, and deduplicated at startup. When exactly one repository is allowed it becomes the implicit default; when several are allowed, callers must select one unless GITNEXUS_MCP_DEFAULT_REPO is also set.
The default repository must resolve to an allowed repository. Invalid, ambiguous, blank, or mismatched configuration fails startup before stdio or HTTP begins serving. The allowlist applies to tools, aliases, discovery, resources, templates, implicit resolution, and embedded HTTP; hidden repository details are not included in selection errors. Setting only GITNEXUS_MCP_DEFAULT_REPO chooses a default without restricting explicit repository selections. An allowed repository whose name is duplicated in the registry must be configured by path, and its context resource is only served for the unique name form.
MCP response budgets
The query, context, and impact tools accept an optional positive-integer maxTokens argument. It bounds the complete formatted MCP response, including hints and error text, using a deterministic four-UTF-8-bytes-per-token estimate. When truncation is required, the response ends with … and remains valid UTF-8.
Set GITNEXUS_MCP_DEFAULT_MAX_TOKENS to apply the same guardrail when callers do not send maxTokens. An explicit tool argument takes precedence. Leaving both unset preserves the existing response byte-for-byte; this is a transport guardrail, not semantic pagination or an exact model-specific tokenizer limit.
CLI Reference
Everyday commands:
gitnexus setup # Configure MCP for detected editors (one-time; -c to select)
gitnexus analyze [path] # Index a repository (or update a stale index)
gitnexus mcp # Start MCP server (stdio) — serves all indexed repos
gitnexus serve # Start local HTTP server (multi-repo) for web UI connection
gitnexus eval-server # Start lightweight evaluation HTTP tools (loopback by default)
gitnexus list # List all indexed repositories
gitnexus status # Show index status for current repo
gitnexus clean # Delete index for current repo
gitnexus wiki [path] # Generate repository wiki from knowledge graph
gitnexus uninstall # Preview removal of GitNexus MCP/skills/hooks (--force to apply)
You can also query the graph directly from the terminal — gitnexus query, context, impact, trace, cypher, detect-changes, and check mirror the MCP tools of the same names, and gitnexus doctor prints runtime platform capabilities.
Authenticated eval-server binding
gitnexus eval-server binds to 127.0.0.1 by default. Loopback bindings do not require authentication. Any non-loopback bind, including 0.0.0.0, a LAN address, or a hostname that resolves to a LAN IPv4 address, requires GITNEXUS_AUTH_TOKEN. Every endpoint then requires an exact Authorization: Bearer <token> header.
GITNEXUS_AUTH_TOKEN='replace-me' gitnexus eval-server --host 0.0.0.0
The token may be set in the shell, .env.local, or .env in the working directory. Precedence is shell > .env.local > .env. Only GITNEXUS_AUTH_TOKEN is read from those files; their other values are not added to the process environment. Keep token files uncommitted.
All analyze flags
gitnexus analyze --force # Full rebuild: re-parse + graph rebuild + FTS rebuild
gitnexus analyze --repair-fts # Fast path: rebuild/verify only FTS indexes on existing index data
gitnexus analyze --skills # Generate repo-specific skill files from detected communities
gitnexus analyze --skip-embeddings # Skip embedding generation (faster)
gitnexus analyze --embeddings [limit] # Enable embedding generation (slower, better search)
gitnexus analyze --skip-agents-md # Preserve custom AGENTS.md/CLAUDE.md gitnexus section edits
gitnexus analyze --skip-skills # Skip installing standard skill files under .claude/skills/ and .agents/skills/
gitnexus analyze --skip-git # Index folders that are not Git repositories
gitnexus analyze --default-branch develop # Branch used in the generated regression-compare example (base_ref)
gitnexus analyze --verbose # Log skipped files when parsers are unavailable
gitnexus analyze --worker-timeout 60 # Increase worker idle timeout for slow parses
gitnexus analyze --workers <n> # Parse worker pool size (>=1; default: cores-1, capped at 16,
# auto-sized to the repo). 0 is rejected — there is no sequential mode.
gitnexus analyze --wal-checkpoint-threshold 67108864 # LadybugDB WAL auto-checkpoint threshold in bytes
# (default 67108864 = 64 MiB; -1 keeps Ladybug stock ~16 MiB)
If analyze reports a worker parse timeout on a large or unusual repository, it keeps running and falls back safely. To give slow worker jobs more time, use --worker-timeout 60 or set GITNEXUS_WORKER_SUB_BATCH_TIMEOUT_MS=60000. For very large files, GITNEXUS_WORKER_SUB_BATCH_MAX_BYTES controls the worker job byte budget.
Embeddings node limit — gitnexus analyze --embeddings generates semantic search vectors with a default 50,000-node safety cap to protect memory on large repositories:
gitnexus analyze --embeddings # default 50,000 node safety cap
gitnexus analyze --embeddings 0 # disable the cap entirely
gitnexus analyze --embeddings 100000 # custom cap
If embeddings are skipped on a large repository, the indexed graph likely exceeds the default cap — re-run with --embeddings 0 or a higher limit.
Repository groups (multi-repo / monorepo service tracking)
gitnexus group create <name> # Create a repository group
gitnexus group add <group> <groupPath> <registryName> # Add a repo. <groupPath> is a hierarchy path
# (e.g. hr/hiring/backend); <registryName> is the
# repo's name from the registry (see `gitnexus list`)
gitnexus group remove <group> <groupPath> # Remove a repo by its hierarchy path
gitnexus group list [name] # List groups, or show one group's config
gitnexus group sync <name> # Extract contracts and match across repos/services
gitnexus group contracts <name> # Inspect extracted contracts and cross-links
gitnexus group query <name> <q> # Search execution flows across all repos in a group
gitnexus group status <name> # Check staleness of repos in a group
gitnexus group impact <name> --target <symbol> --repo <groupPath> # Cross-repo blast radius
Project config (.gitnexusrc)
Commit a .gitnexusrc JSON file at the repo root to preconfigure recurring analyze options per project, instead of re-passing the same flags every run. It is read from the resolved repo root (not .gitnexus/, which is gitignored index storage). CLI flags always override .gitnexusrc.
{
// Default branch used in the generated regression-compare example (base_ref).
// Use this so a project on `develop`/`master` doesn't get "main" rewritten
// over its fix on every analyze. (Alias: "branch".)
"defaultBranch": "develop",
"skipContextFiles": true, // alias of skipAgentsMd: keep your own AGENTS.md/CLAUDE.md
"skipSkills": true, // don't install standard skill files under .claude/skills/ and .agents/skills/
"embeddings": true, // generate embeddings by default
"workerTimeout": 60,
}
A nested analyze block is also accepted (and overrides flat keys for the same option):
{ "analyze": { "defaultBranch": "develop", "skipSkills": true } }
Notes:
- The default branch is resolved as:
--default-branch>.gitnexusrcdefaultBranch/branch> auto-detectedorigin/HEAD>main. skipContextFiles/skipAiContextare aliases forskipAgentsMd— they skip theAGENTS.md/CLAUDE.mdblock only. They do not implyskipSkills.indexOnlyis the stronger option that skips all file injection.- Supported keys:
defaultBranch(branch),skipAgentsMd(skipContextFiles,skipAiContext),skipSkills,indexOnly,stats/noStats,embeddings,dropEmbeddings,name,allowDuplicateName,maxFileSize,workerTimeout,walCheckpointThreshold,workers,embeddingThreads,embeddingBatchSize,embeddingSubBatchSize,embeddingDevice. - The file is JSON only. Unknown keys and invalid values fail fast with an actionable error before analysis starts.
Environment variables
Most analyze knobs are also CLI flags (--workers, --worker-timeout, --max-file-size, --verbose). Use the env-var form when you'd otherwise repeat the same flag every run, or when invoking GitNexus from a long-running host (MCP server, eval-server, CI shell) that already manages its own environment. CLI flags take precedence over env vars; env vars take precedence over built-in defaults.
| Variable | Default | Effect | Tune when… |
|---|---|---|---|
GITNEXUS_WORKER_POOL_SIZE |
cores - 1, capped at 16 |
Parse worker pool size (must be ≥ 1). Equivalent to --workers <n>. The worker pool is the sole parse path — there is no sequential parser, so 0 is rejected with an actionable error (the pool self-heals via quarantine + respawn). |
Constrained containers (cgroup CPU limits) or CI runners with explicit quotas. To narrow down a worker crash set 1 for a single-worker pool — not 0. |
GITNEXUS_PARSE_CHUNK_CONCURRENCY |
2 |
Number of chunks whose file contents may be read into memory in parallel while the pool dispatches the current chunk. Worker dispatch itself stays serial. | Repos large enough to chunk (multi-MB total source) where disk I/O is a measurable fraction of analyze wall-clock. |
GITNEXUS_VERBOSE |
unset | When 1, enables verbose ingestion logs (skipped-file warnings, per-chunk throughput, parse-cache stats). Equivalent to --verbose. |
Debugging an analyze that "completed" but seems to have missed files; tuning --workers / chunk concurrency against observable throughput. |
GITNEXUS_AUTH_TOKEN |
unset | Bearer token required when eval-server binds beyond loopback. May also be read from .env.local or .env; shell values take precedence. |
Exposing the evaluation HTTP tools to a container, VM, or LAN. |
GITNEXUS_PROFILE_DEFERRED |
unset | When 1, emits [deferred-profile] timing/progress logs for the post-chunk deferred resolution band (imports → heritage → buildHeritageMap → legacy call resolution). Implied by GITNEXUS_VERBOSE. |
Diagnosing analyze stalls in "Resolving calls (all chunks)" on large Java/Kotlin repos (issue #1741) without the full verbose ingestion noise. |
GITNEXUS_PROFILE_DEFERRED_SLOW_MS |
3000 (verbose) / 5000 |
Per-file threshold in ms above which processCallsFromExtracted emits a slow file … log line. Parsed via Number(): accepts integers (5000), scientific notation (2.5e3), decimals (.5), and hex (0x10). Non-finite or non-positive values fall back to the default. |
Hunting a few outlier files dominating the deferred call-resolution stage; lower to surface more, raise to focus only on the worst. |
PROF_LBUG_LOAD |
unset | When 1, emits one [lbug-load prof] summary line per loadGraphToLbug call breaking the graph-DB persistence wall into stages (csv-emit / copy-nodes / copy-rels / fallback / total) plus node & edge counts. Zero-cost when unset. |
Attributing large-repo analyze wall time across CSV generation vs. LadybugDB COPY (issue #2203) — the analyze "emit" timing is the scope-resolution bucket, not this DB-write path. |
GITNEXUS_MAX_FILE_SIZE |
512 (KB) |
Walker skip threshold in KB. Hard cap is 32768 (tree-sitter buffer ceiling). Equivalent to --max-file-size <kb>. |
Indexing repos with intentionally-large source files (generated parsers, vendored bundles) that should still be parsed. |
GITNEXUS_WORKER_SUB_BATCH_TIMEOUT_MS |
30000 |
Worker idle timeout in milliseconds before retry/fallback. Equivalent to --worker-timeout <seconds> × 1000. |
Slow-parsing files (large minified JS, deeply-nested TS types) that legitimately need more than 30s. |
GITNEXUS_WORKER_READY_TIMEOUT_MS |
5000 |
Startup budget in milliseconds for a parse worker to load its grammar bindings and report {type:'ready'}. Slots that miss it are treated as startup crashes. |
Slow or heavily loaded hosts where a full pool cold-starting concurrently needs more than 5s, and analyze aborts with "did not report ready within 5000ms". |
GITNEXUS_FTS_STEMMER |
porter |
Stemmer used when rebuilding BM25/FTS indexes. Use none for CJK-heavy repositories, or a language stemmer such as german, french, or spanish for matching repository comments. Re-run gitnexus analyze --repair-fts after changing it. |
Keyword search quality is poor for non-English comments or identifiers under English stemming. |
GITNEXUS_WAL_CHECKPOINT_THRESHOLD |
67108864 (64 MiB) |
LadybugDB WAL auto-checkpoint threshold in bytes. Equivalent to --wal-checkpoint-threshold <bytes>. -1 keeps LadybugDB's stock threshold (~16 MiB). Larger thresholds reduce checkpoint frequency but increase the WAL size at rotation time — choose a smaller value on disk-constrained environments. |
You need a larger or smaller WAL auto-checkpoint threshold for your analyze workload. |
GITNEXUS_LBUG_BUFFER_POOL_SIZE |
min(2 GiB, 80% RAM) | LadybugDB buffer-pool ceiling in bytes for every GitNexus database (analyze, MCP server, serve, group bridges). 0 restores LadybugDB's native unbounded default of 80% of system RAM; invalid values warn and fall back to the default (#2557). During analyze the pool is right-sized to the graph, scaled on non-4 KiB-page hosts by the page-size granule ratio up to min(2 GiB × pageSize/4 KiB, 80% RAM) (#2631); this env var overrides all of that as an absolute value. |
A long-lived gitnexus mcp or a big incremental analyze uses too much memory, or a huge repo's working set genuinely needs a pool larger than 2 GiB. |
GITNEXUS_LBUG_MAX_DB_SIZE |
17179869184 (16 GiB) |
Maximum size in bytes of a single LadybugDB database file — an mmap/disk-address-space ceiling, not a memory limit (it does not constrain the buffer pool). Invalid values silently fall back to the default. | Indexing a genuinely huge monorepo whose on-disk graph index approaches 16 GiB. |
GITNEXUS_WORKER_SUB_BATCH_MAX_BYTES |
8388608 (8 MB) |
Per-job byte budget the pool will send to a worker in one postMessage. |
Very large individual files; mostly diagnostic — bumping past 8 MB risks structured-clone memory pressure. |
GITNEXUS_WORKER_MAX_RESPAWNS_PER_SLOT |
3 |
Max replacement spawns per worker slot before the slot is dropped from the active rotation. Bounds respawn loops on a chronically-crashing slot. | Hosts where a flaky worker should retry more (raise) or fail-fast (lower) before the slot is dropped. |
GITNEXUS_WORKER_MAX_CUMULATIVE_TIMEOUT_MS |
5 × subBatchTimeoutMs |
Total retry wall-time budget per job before quarantining. Combined with timeoutBackoffFactor, prevents exponentially-growing retries from stalling for hours. |
Slow files that legitimately need long total retry windows; lower to fail-fast on stalls. |
GITNEXUS_WORKER_CONSECUTIVE_FAILURE_THRESHOLD |
max(3, poolSize) |
Per-slot consecutive deaths before the pool's circuit breaker trips. After tripping, every subsequent dispatch rejects until a fresh pool is created. | Hosts where a SIGSEGV-prone native grammar should trip the breaker sooner; CI runners that should fail loudly. |
GITNEXUS_WORKER_SHUTDOWN_DRAIN_MS |
30000 |
Max wait at pool shutdown for a retired worker still inside native code. The worker is terminated at its next JS-safe point instead of mid-native-call (which aborts the whole process with Napi::Error, #2432); on expiry it is left running, unref'd, and terminated when it surfaces. |
Shutdown latency matters more than draining a wedged worker (lower), or a legitimately-slow native grammar needs longer to surface (raise). |
GITNEXUS_CPP_CAPTURE_BUDGET_MS |
20000 |
Per-file wall-clock budget for C++ capture extraction. On breach the file keeps the captures accumulated so far and logs a warning — the worker returns to JS instead of stalling in native-heavy loops (#2432). 0 expires immediately. |
Pathological generated C++ that still exceeds the budget after the indexed lookups; raise for completeness, lower to fail-fast. |
GITNEXUS_CHUNK_BYTE_BUDGET |
2097152 (2 MB) |
Chunk boundary used for cache-key composition and dispatch. Smaller = finer-grained cache hits but more dispatch overhead. | Tuning incremental-analyze cache behavior on monorepos. |
GITNEXUS_NO_GITIGNORE |
unset | When set, skips .gitignore parsing. .gitnexusignore is still honored. |
Indexing a repo whose .gitignore excludes files you actually want indexed (e.g., generated code committed for cross-repo lookup). |
GITNEXUS_SKIP_OPTIONAL_GRAMMARS |
unset | When =1 strictly, skips the vendored grammar materialize for tree-sitter-dart, tree-sitter-proto, tree-sitter-swift, and tree-sitter-kotlin at install time (and the Dart/Proto source builds). Those four won't be parsed; the install still succeeds. |
Installing on a host without a C++ toolchain or where the vendored prebuilds don't match; willing to skip Dart/Proto/Swift/Kotlin parsing. |
GITNEXUS_MCP_READ_ONLY |
unset | Set to 1 to expose only proven single-repository read tools and resources; 0 disables the policy and any other value fails startup. |
The MCP server runs in an environment where graph mutation, raw Cypher, and cross-repository group routing must be unavailable. |
GITNEXUS_MCP_ALLOWED_REPOS |
unset | Comma-separated allowlist of canonical indexed repository names or absolute paths. Invalid, ambiguous, or blank entries fail startup. | One MCP process must expose only a bounded subset of the repositories in the global registry. |
GITNEXUS_MCP_DEFAULT_REPO |
unset | Canonical indexed repository name or absolute path used when a tool or resource omits its repository. Must belong to the allowlist when one is set. | Several repositories are available but unqualified MCP calls should resolve deterministically. |
GITNEXUS_MCP_DEFAULT_MAX_TOKENS |
unset | Default positive-integer response budget for MCP query, context, and impact, estimated at four UTF-8 bytes per token. Explicit maxTokens wins. |
Long MCP responses consume too much model context and callers cannot reliably add a per-request budget. |
GITNEXUS_PUBLIC_ORIGIN |
unset | The single browser origin serve is reached through, added to the CORS allowlist and to the write-route origin guard. A wildcard bind (0.0.0.0) has no host identity, so without this the server's own UI is refused. Setting it currently refuses to start: serve has no authentication, requests carrying no Origin header already reach POST /api/analyze and DELETE /api/repo, and this is the setting that would admit browser writes on top of that. Matching rules for when the gate lifts: the hostname must match exactly, and so must the scheme. A value with no scheme (app.example.com) means https, since a bare host comes from platform service discovery and those terminate TLS; spell out http://app.example.com for plain HTTP. An explicit port must match; with no port, any port on that hostname is accepted. Anything that is not one reachable host (a list, *, a bare port number, a :0 port, a trailing dot) warns at startup and allows nothing. |
gitnexus serve runs behind a reverse proxy or on a wildcard bind, and the UI's index/delete requests return origin_not_allowed. |
GITNEXUS_TRUST_PROXY |
loopback, linklocal, uniquelocal |
Express trust proxy value — which upstream hops may set X-Forwarded-*, and so what the per-IP rate limiter reads as the client IP. Set it to the exact number of proxies you control. Every hop past that is one more entry of the chain the caller gets to write. false/no/off (and a 0 hop count) trust no hop; a proxy list Express can compile (loopback, 10.0.0.0/8, 127.0.0.1) names them instead. true/yes/on is rejected: it reads the client-controlled leftmost X-Forwarded-For entry, so a spoofed chain earns a fresh rate-limit key per request, and express-rate-limit rejects it too (ERR_ERL_PERMISSIVE_TRUST_PROXY). Counts above 16 are rejected as well, as a sanity ceiling rather than a safety boundary. Any invalid value warns and falls back to the default. Bind non-loopback with this unset and serve warns: a load balancer outside the private ranges is untrusted, so every request keys to the balancer and the per-IP limit becomes one shared limit. |
serve sits behind a load balancer outside the private ranges (AWS ALB, Cloudflare, CGNAT), where every request otherwise collapses to the proxy hop and rate limiting goes global. |
gitnexus uninstall
gitnexus uninstall reverses gitnexus setup — it removes the GitNexus MCP entries, hooks, and skill directories it added to each detected editor. Skill directories are identified by bundled gitnexus skill name (e.g. gitnexus-cli/), so if you customized files inside an installed skill directory, back them up first. It is a dry-run preview by default and prints the exact paths it would remove; pass --force to apply. Per-repo indexes (gitnexus clean --all) and the global npm package (npm uninstall -g gitnexus) are left for you to remove.
Publishing to understand-quickly (opt-in)
looptech-ai/understand-quickly is a public registry of code-knowledge graphs that lists gitnexus@1 as a first-class format. After registering your repo once (npx @understand-quickly/cli add or the wizard), gitnexus publish fires a single repository_dispatch event so the registry resyncs your entry on demand instead of waiting for the nightly job.
It is opt-in and a no-op without UNDERSTAND_QUICKLY_TOKEN — a fine-grained GitHub PAT with Repository dispatches: write on the registry repo. Nothing else happens; no graph file is uploaded. See the protocol spec for the full contract.
How It Works
GitNexus builds a complete knowledge graph of your codebase through a multi-phase indexing pipeline:
- Structure — walks the file tree and maps folder/file relationships
- Parsing — extracts functions, classes, methods, and interfaces using Tree-sitter ASTs
- Resolution — resolves imports, function calls, heritage, constructor inference, and
self/thisreceiver types across files with language-aware logic - Clustering — groups related symbols into functional communities
- Processes — traces execution flows from entry points through call chains
- Search — builds hybrid search indexes for fast retrieval

Multi-Repo Architecture
GitNexus uses a global registry so one MCP server can serve multiple indexed repos. No per-project MCP config needed — set it up once and it works everywhere.
Each gitnexus analyze stores the index in .gitnexus/ inside the repo (portable, gitignored) and registers a pointer in ~/.gitnexus/registry.json. When an AI agent starts, the MCP server reads the registry and can serve any indexed repo. LadybugDB connections are opened lazily on first query and evicted after 5 minutes of inactivity (max 5 concurrent). If only one repo is indexed, the repo parameter is optional on all tools — agents don't need to change anything.

Impact Analysis
impact({target: "UserService", direction: "upstream", minConfidence: 0.8})
TARGET: Class UserService (src/services/user.ts)
UPSTREAM (what depends on this):
Depth 1 (WILL BREAK):
handleLogin [CALLS 90%] -> src/api/auth.ts:45
handleRegister [CALLS 90%] -> src/api/auth.ts:78
UserController [CALLS 85%] -> src/controllers/user.ts:12
Depth 2 (LIKELY AFFECTED):
authRouter [IMPORTS] -> src/routes/auth.ts
Options: maxDepth, minConfidence, relationTypes (CALLS, IMPORTS, EXTENDS, IMPLEMENTS), includeTests, limit (max symbols per depth, default 100), offset (pagination start per depth), summaryOnly (counts and risk only, omits symbol list)
Disambiguation — when several symbols share the target name, impact returns a ranked ambiguous candidate list instead of guessing. Narrow it with target_uid (exact, zero-ambiguity), file_path, or kind (Function, Class, Method, …). From the CLI these are --uid, --file, and --kind, matching gitnexus context:
gitnexus impact get_embeddings # → ambiguous: lists ranked candidates
gitnexus impact get_embeddings --file src/embed.py # → resolves to the one in that file
gitnexus impact get_embeddings --uid "Function:src/embed.py:get_embeddings" # exact

Wiki Generation
Generate LLM-powered documentation from your knowledge graph:
# Requires an LLM API key (OPENAI_API_KEY, etc.)
gitnexus wiki
# Use a custom model or provider (default model: minimax/minimax-m2.5)
gitnexus wiki --model gpt-4o
gitnexus wiki --base-url https://api.anthropic.com/v1
# Force full regeneration
gitnexus wiki --force
# Increase the timeout or retries for large codebases or slow LLM providers
gitnexus wiki --timeout <seconds> # LLM request timeout in seconds (default: disabled)
gitnexus wiki --retries <n> # Max LLM retry attempts per request (default: 3)
# Allow a specific LAN/self-hosted HTTP LLM host (HTTPS is preferred for remote endpoints)
gitnexus wiki --base-url http://llama-box.local:8080/v1 --allow-insecure-connection llama-box.local
# Or set a comma-separated host allowlist:
GITNEXUS_ALLOW_INSECURE_CONNECTION=llama-box.local,192.168.1.23
# Change the output language
gitnexus wiki --lang <lang> # e.g. english, chinese, spanish, japanese
For safety, http:// LLM base URLs are allowed by default only for loopback hosts (localhost, 127.0.0.1, ::1). --allow-insecure-connection and GITNEXUS_ALLOW_INSECURE_CONNECTION accept exact hostnames or IP addresses only; do not include schemes, ports, paths, credentials, or wildcards.
The wiki generator reads the indexed graph structure, groups files into modules via LLM, generates per-module documentation pages, and creates an overview page — all with cross-references to the knowledge graph.
Web UI (browser-based)
A client-side graph explorer and AI chat — your code never leaves your machine.
Try it now: gitnexus.vercel.app — run npx gitnexus@latest serve locally and the page auto-connects to your local backend.
The web UI uses the same indexing pipeline as the CLI but runs entirely in WebAssembly (Tree-sitter WASM, LadybugDB WASM, in-browser embeddings). It's great for quick exploration but limited by browser memory for larger repos.
Local Backend Mode: run gitnexus serve and open the web UI — it auto-detects the server and shows all your indexed repos, with full AI chat support. No re-upload, no re-index. The agent's tools (Cypher queries, search, code navigation) route through the backend HTTP API automatically.
Run the frontend locally
git clone https://github.com/abhigyanpatwari/gitnexus.git
cd gitnexus/gitnexus-shared && npm install && npm run build
cd ../gitnexus-web && npm install
npm run dev
# Then in another terminal, start the backend the frontend connects to:
npx gitnexus@latest serve
Docker
docker compose up -d
This starts the server on http://localhost:4747 and the web UI on http://localhost:4173. The UI auto-detects the server because the browser runs on the host and reaches the container via the mapped port.
The official setup ships two signed images, published identically to GitHub Container Registry (GHCR) and Docker Hub — same build, same digest, same Cosign signature:
| Purpose | GHCR (default in docker-compose.yaml) |
Docker Hub mirror |
|---|---|---|
CLI / gitnexus serve backend (HTTP API on port 4747, MCP, indexer) |
ghcr.io/abhigyanpatwari/gitnexus:latest |
akonlabs/gitnexus:latest |
Static web UI (port 4173) |
ghcr.io/abhigyanpatwari/gitnexus-web:latest |
akonlabs/gitnexus-web:latest |
A named volume (gitnexus-data) persists the global registry, indexes, and cloned repos at /data/gitnexus inside the server container. To make repos on your host machine indexable, set WORKSPACE_DIR before bringing the stack up:
WORKSPACE_DIR=$HOME/code docker compose up -d
# Inside the server container the directory is mounted read-only at /workspace.
docker compose exec gitnexus-server gitnexus index /workspace/my-repo
Heads-up — image rename. Earlier releases published the web UI under
ghcr.io/abhigyanpatwari/gitnexus. That slug now hosts the CLI/server image and the UI moved toghcr.io/abhigyanpatwari/gitnexus-web. Previous tags remain pullable, but new versions are only published under the new slugs — update yourdocker run/ compose files (or just adopt the bundled compose).
Direct docker run & env file
# Server
docker run --rm -d \
--name gitnexus-server \
-p 4747:4747 \
-v gitnexus-data:/data/gitnexus \
ghcr.io/abhigyanpatwari/gitnexus:latest
# Web UI
docker run --rm -d \
--name gitnexus-web \
-p 4173:4173 \
ghcr.io/abhigyanpatwari/gitnexus-web:latest
Optional env file (override image tags, container names, ports, workspace dir):
cp .env.example .env
docker compose --env-file .env up -d
Files:
- Dockerfile.web — builds
gitnexus-sharedandgitnexus-web, then serves the production frontend. - Dockerfile.cli — builds the CLI/server (with its native deps) and runs
gitnexus serve --host 0.0.0.0. - docker-compose.yaml — starts both signed images side by side.
- .env.example — overrides for image names, container names, ports, and the workspace mount.
Versioning & supply-chain protection (Cosign signatures, provenance, Kubernetes admission policy)
The Docker images are version-locked to the npm package:
- Stable images are only published from
vX.Y.Zgit tags (viadocker.ymltriggered directly by the tag push), and the workflow refuses to build unless the tag exactly matchesgitnexus/package.json's version. Soghcr.io/abhigyanpatwari/gitnexus:1.6.2(and its Docker Hub mirrorakonlabs/gitnexus:1.6.2) is byte-for-byte the same release asnpm install gitnexus@1.6.2— no drift, no floating builds frommain. Both registries receive the same digest from a single build step, so you can pull from either and the signature verifies identically. - Release-candidate images (e.g.
:1.7.0-rc.1) are published alongside each RC npm release. They are built bypublish.ymlcallingdocker.ymlas a reusable workflow after the RC tag is created and pushed. :latestis auto-promoted only from non-prerelease tags by the Docker metadata action, so it always points at a real, npm-published version.
Both images are signed with Cosign keyless signing using the workflow's GitHub OIDC identity, and shipped with build provenance and SBOM attestations. This is your protection against supply-chain attacks: even if an attacker republishes a same-named image elsewhere (or somehow pushes to a typo-squatted registry), they cannot forge a Cosign signature tied to abhigyanpatwari/GitNexus's docker.yml. Always verify before pulling into sensitive environments.
Stable releases — signed from the v* tag ref:
cosign verify ghcr.io/abhigyanpatwari/gitnexus:1.6.2 \
--certificate-identity-regexp '^https://github\.com/abhigyanpatwari/GitNexus/\.github/workflows/docker\.yml@refs/tags/v[0-9]+\.[0-9]+\.[0-9]+(-[a-zA-Z0-9.]+)?$' \
--certificate-oidc-issuer https://token.actions.githubusercontent.com
# Same signature verifies the Docker Hub mirror (identical digest):
cosign verify docker.io/akonlabs/gitnexus:1.6.2 \
--certificate-identity-regexp '^https://github\.com/abhigyanpatwari/GitNexus/\.github/workflows/docker\.yml@refs/tags/v[0-9]+\.[0-9]+\.[0-9]+(-[a-zA-Z0-9.]+)?$' \
--certificate-oidc-issuer https://token.actions.githubusercontent.com
The regex pins the certificate identity to this repo's docker.yml workflow run from a v* tag — rejecting unsigned images, images signed by other workflows, and images signed from unprotected refs. It is identical for both registries because both sets of tags were signed at the same digest in one workflow run.
Release candidates — signed from refs/heads/main (the caller's ref when publish.yml invokes docker.yml as a reusable workflow):
cosign verify ghcr.io/abhigyanpatwari/gitnexus:1.7.0-rc.1 \
--certificate-identity 'https://github.com/abhigyanpatwari/GitNexus/.github/workflows/docker.yml@refs/heads/main' \
--certificate-oidc-issuer https://token.actions.githubusercontent.com
You can also inspect the build provenance and SBOM:
cosign download attestation ghcr.io/abhigyanpatwari/gitnexus:1.6.2 \
--predicate-type https://slsa.dev/provenance/v1
Kubernetes: enforce signatures at admission. Ship the bundled ClusterImagePolicy so the Sigstore policy-controller rejects any GitNexus pod whose image is not signed by this repo's docker.yml running from a vX.Y.Z tag — the same identity the cosign verify snippet above pins.
# 1. Install the controller (one-time, cluster-wide)
helm repo add sigstore https://sigstore.github.io/helm-charts && helm repo update
helm install policy-controller -n cosign-system --create-namespace \
sigstore/policy-controller
# 2. Opt your namespace in
kubectl label namespace <your-ns> policy.sigstore.dev/include=true
# 3. Apply the policy
kubectl apply -f deploy/kubernetes/cluster-image-policy.yaml
After this, attempting to deploy an unsigned image — or one signed by anything other than abhigyanpatwari/GitNexus's docker.yml at a v* tag — fails the admission webhook before a pod is ever created. This turns the verifiable signature into an enforced policy, which is the supply-chain control most clusters actually need.
