Both agents use Strix's existing +agent loop, native filesystem and shell tools, and saved conversations. They share +one persistent sandbox. The assignments live in `strix/agents/prompts/fix_repair.jinja` and +`fix_review.jinja`, with shared workspace instructions in `fix_workspace.jinja`. + +Repair receives the finding, evidence, affected locations, suggested remediation, +and available reproduction details. It makes a minimal fix, adds a regression test +using the repository's framework, and hands the test location and commands to review. +Review receives the finding, patch, repair summary, and command history. It runs +the customer's relevant existing unit tests and the regression test, then judges +whether the change addresses the issue without obvious regressions. It can make +small corrections and rerun affected tests. Optional improvements are follow-ups. + +## Completion and handoffs + +Agents finish through Strix's `agent_finish` tool: + +- Repair: `done` starts review; `blocked` stops and preserves work. +- Review: `approved` finishes; `changes_requested` resumes repair with feedback; + `blocked` stops and explains the missing prerequisite or failed required tests. + +Each agent retains its own conversation across handoffs. Test selection and +interpretation belong to the reviewer. Code checks source identity, requires a +nonempty patch, and ensures delivery matches the final workspace approved by review. +Reviewer corrections are included in that workspace. Changes after approval block +delivery; they do not automatically start another repair. + +## Files and evidence + +- `strix/fix/prepare.py`: routes repair and review decisions. +- `strix/fix/runtime.py`: supplies assignments to native Strix agents, routes outcomes, + and records tool results and usage. +- `strix/fix/workspace.py`: stages source and sanitized Git metadata in the sandbox, + then exports changes to the host's artifact mirror. + +The public `strix.fix.runtime.run_isolated_fix_preparation()` entry point takes a +request and a clean Git checkout. It creates a job-owned clone and artifact mirror; +the supplied checkout is never edited. It uses the configured native sandbox +backend (Docker in OSS; registered cloud backends work for hosted callers). + +The agents execute customer code only inside the sandbox. The host mirror is used +for artifact construction. Changes are saved when an agent completes or is +interrupted. Interrupted runs retain useful work without claiming approval. + +The artifact contains the patch, changed files, `execution.json`, +`agent-sessions.json`, and `tool-results.jsonl`. Logs stay outside repository source. +Command records retain the output returned by native tools, including their output +limits. Agents can redirect lengthy test output to a sandbox file and inspect it +with the native tools. Command exit codes are evidence for review, not proof of +security or coverage by themselves. + +## Budgets and delivery + +`max_agent_turns` defaults to Strix's normal 500 turns per agent, counted across +continuations. The configurable job deadline defaults to 7,200 seconds. An optional +`max_budget_usd` applies across both agents using SDK usage estimates. The legacy +request field `max_repair_attempts` is accepted but does not control this loop. + +New results use `validation_mode: agent_review`. They contain the review decision, +summary, final patch identity, and command history. The app delivers approved +results as draft PRs and includes the review and testing limitations. Historical +`native_tests` and `paired` records remain readable by the app's compatibility code; +new runs do not produce those proof structures. + +## Run from the OSS CLI + +Use the same configured model and Docker environment as a normal Strix scan: + +```bash +strix fix --repo ./repo --finding strix_runs/my-scan/vulnerabilities.json \ + --finding-id vuln-0001 --output ./fix-result/result.json +``` + +A file containing one finding or a `FixCandidateV1` also works. Findings need their +recorded `fix_candidate.source_identity`; the command does not guess which revision +an old finding described. The checkout must be clean and at that recorded commit. +This first CLI version supports Git sources, not restoration of uploaded archives. + +Automation and benchmarks can pass the existing request format: + +```bash +strix fix --repo ./repo --request request.json --output ./fix-result/result.json +``` + +`--workspace` is an alias for `--repo`. `--artifact` overrides the archive path; +`--max-agent-turns`, `--timeout`, and `--max-budget` override request budgets. +Outputs are result JSON, a readable Markdown review, a patch, and the full ZIP +artifact. Without `--output`, they go in a new `strix_runs/fix-…` directory. Use an +output directory outside the source checkout to keep it clean for the next run. +Exit codes: 0 approved, 2 incomplete/blocked/stale, 1 startup or input failure, +130 interrupted. Interruptions save any checkpointed work in the ZIP archive. +Partial patches and their limitations are retained when review cannot approve. +The CLI does not push changes or publish PRs. + +## Hosted integration and credentials + +The hosted runner in `strix-pro` restores authorized source, calls this exact OSS +entry point, and sends the result to the app. The app owns account permissions and +publishing through the connected Git provider. Neither supplies a separate repair +or review implementation. + +Fix requests cannot select environment variables from the runner. The removed +credential forwarding option accepts legacy empty lists only; nonempty lists fail +validation. No host credential names or prefix blocklists are needed. Customer test +credentials are not injected by this feature; tests needing them must report the +missing setup accurately. + +## Local checks + +`make test-fix-reliability` exercises the actual Strix loop and native SDK tools +with scripted model responses and local fixture tests. It covers handoffs, reviewer +corrections, blocked or interrupted work, and artifact integrity. It does not make +live model calls or evaluate patch quality; the benchmark covers those questions. diff --git a/strix/agents/prompt.py b/strix/agents/prompt.py index 09e4733b0..69ae1e502 100644 --- a/strix/agents/prompt.py +++ b/strix/agents/prompt.py @@ -3,7 +3,7 @@ from __future__ import annotations import logging -from typing import Any +from typing import Any, cast from jinja2 import Environment, FileSystemLoader, select_autoescape @@ -17,6 +17,16 @@ logger = logging.getLogger(__name__) _PROMPT_DIRNAME = "prompts" +def render_fix_prompt(*, review: bool, workspace_root: str) -> str: + """Render a fix assignment without loading scan-only skills.""" + env = Environment( + loader=FileSystemLoader(get_strix_resource_path("agents", _PROMPT_DIRNAME)), + autoescape=select_autoescape(enabled_extensions=(), default_for_string=False), + ) + template = "fix_review.jinja" if review else "fix_repair.jinja" + return str(env.get_template(template).render(workspace_root=workspace_root)) + + def _resolve_skills( *, requested: list[str] | None, @@ -101,7 +111,11 @@ def render_system_prompt( is_diff_scoped=is_diff_scoped, ) skill_content = load_skills(skills_to_load) - env.globals["get_skill"] = lambda name: skill_content.get(name, "") + + def get_skill(name: str) -> str: + return skill_content.get(name, "") + + cast("dict[str, Any]", env.globals)["get_skill"] = get_skill rendered = env.get_template("system_prompt.jinja").render( loaded_skill_names=list(skill_content.keys()), diff --git a/strix/agents/prompts/fix_repair.jinja b/strix/agents/prompts/fix_repair.jinja new file mode 100644 index 000000000..8830191eb --- /dev/null +++ b/strix/agents/prompts/fix_repair.jinja @@ -0,0 +1,12 @@ +Fix the supplied vulnerability with a concise, minimal change that follows +repository conventions and preserves normal behavior.
