生命周期、事务处理和 SQL 插值。 +- `missing_tests`：源码变更缺少测试变更。 +- `duplicate_findings`：重复问题模式，用于去重测试。 +- `sandbox_failure`：沙箱失败被记录，任务不崩溃。 +- `secret_redaction`：报告和数据库中脱敏 secret。 +- `sandbox_timeout`：沙箱超时被记录，任务不崩溃。

reusable Skill, sandbox execution, Filter governance, SQLite persistence, structured findings, and monitoring audit output. + +## What It Covers + +- `skills/code-review/SKILL.md` with rule docs and sandbox scripts. +- Unified diff, PR patch, repo path, file-list, stdin, and fixture input parsing. +- CLI and `run_review()` default to the production `container` sandbox; explicit `--dry-run` or `--sandbox fake` uses the fake sandbox for CI and no-key development. +- Container/Cube-ready sandbox adapter boundary, with local mode only as explicit fallback. +- SQLite records for task, diff, sandbox run, filter decision, finding, monitoring summary, and final report. +- Secret redaction before report and database writes. +- Normal reviews do not execute SDK `skill_run` outside the sandbox policy; `--skill-smoke` verifies SDK `skill_load` / `skill_run` separately. +- Deduped findings plus warnings and `needs_human_review`. +- Review rules cover seven categories: security risks, async errors, resource leaks, test gaps, secret leaks, database transactions, and database connection lifecycle, with Python AST/taint assistance. +- Sandbox-side scanner aggregation runs offline bandit, ruff, and detect-secrets by default; network-backed semgrep auto scanning, URLs/domains in test commands, and implicit network commands such as pip/git/npm/ssh must pass Filter. +- Sandbox output uses a combined stdout/stderr byte budget; scanner materialization rejects path escapes. +- `rules.json` and `filter_policy.json` provide rule configuration, Filter policy-as-code, and workspace path allowlists. +- `# cr-agent: ignore=` suppresses a specific rule and records ignored counts. +- `agent/native_agent.py` exposes the complete review pipeline as a `FunctionTool` for `LlmAgent`. +- `agent/native_filter.py` exposes the same governance policy as a tRPC-Agent `BaseFilter` adapter. +- `ReviewStore.from_url()` supports `sqlite:///...` and keeps explicit Postgres/MySQL extension points. +- Reports include confidence thresholds, dedupe counts, Filter summaries, sandbox summaries, monitoring metrics, and actionable recommendations. + +## Run + +From the repository root: + +```bash +python3 examples/skills_code_review_agent/run_review.py --fixture security_issue --dry-run +``` + +Run all public fixtures: + +```bash +for f in clean security_issue async_resource_leak db_lifecycle missing_tests duplicate_findings sandbox_failure secret_redaction sandbox_timeout sandbox_large_output sandbox_secret_output; do + python3 examples/skills_code_review_agent/run_review.py --fixture "$f" --dry-run --output-dir /tmp/cr-agent-"$f" +done +``` + +Verify the SDK-native Skill path. This calls `skill_load(skill_name="code-review")` +and then runs `scripts/diff_summary.py` through `skill_run`.
