Name the rule when you lean +on an inferred edge. + +### 4. Reproduce it before explaining it + +`orca_replay` re-runs the recording and reports what could not be reproduced — divergences, and +requests the recording could not serve. + +**What "offline" covers, and what it does not.** Every model response comes from the trace and the +proxy forwards nothing upstream, so no provider is contacted and no tokens are spent. An unmatched +request halts the replay rather than falling through to the network, unless `--loose` was asked for. + +That covers the model traffic. It does not cover the agent's own subprocesses: unless the recording +used `--tls-intercept` — in which case replay re-establishes interception for the hosts it recorded +— a `curl`, `npm install`, `git push` or database call inside a recorded shell command goes +straight out. Replay is not a sandbox; only a network-isolated container makes it one. + +**What a matching replay proves, and what it does not.** It shows the recorded decisions reproduce +against today's environment. It cannot show the failure is deterministic, because the model is not +being asked again — the same recorded responses are served back. If the user wants to know whether a +fresh run would fail the same way, say that replay cannot answer it; that needs real runs. + +**Replay re-executes the agent, not just its model traffic.** The recorded model responses are +served from the trace, but the agent process runs again for real — so every shell command it issued +runs again too. `worktree: true` isolates repository files and nothing else. Anything the run +touched outside the tree — `/tmp`, Docker, a local database, a package manager, another host — is +mutated a second time. + +**Hard gate before every replay.** Before calling `orca_replay`, the agent MUST use `orca_show_run` (or an equivalent trace view) to enumerate the complete shell-command list, including commands that may touch `/tmp`, Docker, databases, package managers, or remote hosts. It MUST show that list to the user and obtain explicit approval for the exact replay. If any command reaches outside the worktree, approval MUST name those external effects or the replay MUST run inside a genuinely isolated container. `worktree: true` protects repository files only; it does not authorize external side effects. Do not infer approval from silence, a previous approval, or the fact that the original run was recorded. A run that only read files and edited the repository is free and repeatable, but it still requires this preview-and-confirm gate. + +**Pass `worktree: true`.** It replays into a scratch copy and leaves the working tree alone. + +Without it, replay is destructive for as long as it runs: it restores the recorded filesystem over +the working tree and puts the tree back when the replay ends. Uncommitted work is absent in the +meantime, and stays absent if the replay is interrupted before it can restore. Run an in-place +replay only when the user has been told that and has agreed to it. "They do not appear to be +typing" is not consent. + +A replay reporting `reused=3/5` on an interactive recording is not a partial failure. Harnesses make +calls for themselves — a quota probe, a session-naming request — and a replay does not repeat them. + +### 5. Only then consider comparing models + +`orca_compare` forks one run onto several models from the same checkpoint: same files, same +conversation prefix, so the model is the only variable. Pick the fork point with `orca_checkpoints` +and pass it as `from`. + +Grade with `verify` — a shell command whose exit code is the verdict. Use something the repository +already declares (`"npm test"`, `"npm run typecheck"`) or an explicitly local binary +(`"./node_modules/.bin/tsc --noEmit"`), not `npx `: with no local install, npx runs whatever +the registry has under that name, and `npx tsc` resolves a package deprecated in 2016 that is not +TypeScript. + +**`orca_compare` uploads the recording to other people's models, and spends real money doing it.** +Each model named receives the same files and conversation prefix the original run had — so whatever +that run touched (source, prompts, configuration, anything a credential was pasted into) is sent to +every provider behind those model ids. + +**And each fork is a live agent, not a replay.** From the fork point onward the model is really +being asked, and whatever it decides to do, it does — its shell commands execute for real, and so +does the `verify` command you pass. Each fork gets its own worktree, so repository files are +isolated per model; nothing outside the tree is. A fork can also take actions the original run never +took, because it is a different model making fresh decisions. + +So the approval has three parts, and they are not the same question: + +1. **Disclosure** — what context is uploaded, and to which providers. Approving a bill is not + approving a disclosure, and the two need separate answers when the recording is from a private + codebase. `orca scrub` is for when the comparison is worth running but the trace is not safe to + send as-is. +2. **Side effects** — what the recorded run did outside its worktree, since each fork may repeat it + and may go further. Same check as step 4, `orca_show_run`, and the same answer if it reached + Docker, a database, a deployment or another host: get approval for that specifically, or run the + comparison in an isolated environment. +3. **Cost** — how many models times how many forks. + +Never run it to satisfy curiosity the user did not express. + +## If there is no recording yet + +Say so plainly rather than falling back to guessing, and offer to start one. + +If `orca` is already installed: + +```console +orca record claude # or codex, opencode, openclaw, grok +``` + +If it is not installed, stop and ask the user to install it separately. Do not install packages, change global state, or use a package-manager command as part of this Skill. + +`orca record ` runs the agent unmodified behind a local proxy. Nothing about the agent +changes; two environment variables get set. Recording a session now is what makes the next "why did +it do that" answerable. + +For a run started with a prompt in argv — `orca record claude -- -p "…"` — the replay is exact. A +session someone typed into replays approximately, because the prompts were never on the wire and +are recovered from the harness's own transcript; `orca replay` says which is which rather than +papering over it. + +## Sharing a run with someone else + +`orca export last -o run.html` writes one self-contained file. A trace holds whatever the run held, +so run `orca scrub` before sending one anywhere. + +Scrubbing is best-effort, not a guarantee. It matches known key shapes and high-entropy strings; it +cannot know that a particular internal hostname, customer name, or unreleased feature is +confidential to this user. So scrub, then have the user look at what is actually going out, and get +their agreement — do not describe a scrubbed trace as safe on the strength of the scrubber alone. + +## Limitations + +- **It only sees what was recorded.** Runs started without `orca record` leave no trace, and + nothing here recovers them. The answer to "why did it do that" in an unrecorded session is + honestly "there is no recording", not a reconstruction. +- **A typed session replays approximately, not exactly.** Prompts entered at a terminal were never + on the wire; orca recovers them from the harness's own transcript. Only a run started with the + prompt in argv (`orca record claude -- -p "…"`) replays byte-for-byte. +- **Some turns are not repeated.** A harness makes calls for itself — a quota probe, a + session-naming request — and a replay steps over them. Tools that need a person + (`AskUserQuestion`, plan mode) are absent when the same agent runs without one, which can make a + replayed request differ from the recorded one by enough to halt. +- **`inferred` edges are not evidence.** They are derived from a named rule at query time. Treat + them as a reading of the trace, never as something the recorder witnessed. +- **Not every harness is recordable.** Agents that read no base-URL variable and pin their own + origin need `--tls-intercept`, and some cannot be reached at all. A recording that came back + empty means the harness was not captured, not that nothing happened. +- **Replay is not a time machine, and not a sandbox.** It reproduces the agent's side of the run + against today's world. External state the run depended on — a database row, a remote branch, the + clock — is whatever it is now, and the run's own shell commands reach it for real. +- **A matching replay is not a determinism result.** The model is not re-asked; its recorded + responses are served back. Whether a fresh run would fail the same way is a different question + that replay cannot answer. + +## Tools + +| tool | arguments | notes | +|---|---|---| +| `orca_list_runs` | — | newest first, names the parent of each fork | +| `orca_show_run` | `run` | the full timeline | +| `orca_checkpoints` | `run` | where a fork can start | +| `orca_graph` | `run`, `to` | causal edges; `to` narrows to one chain | +| `orca_replay` | `run`, `worktree` | offline, free, repeatable | +| `orca_compare` | `run`, `models`*, `from`, `verify` | **spends real tokens** | + +`run` accepts a run id or `"last"`, and defaults to `"last"`.
