+# Skills Code Review Agent
+
+This example implements Issue #92: a skills-based automatic code review agent with sandbox execution, SQLite persistence, Filter governance, redaction, deduplication and audit reports.
+
+## Quick Start
+
+This example follows the same layout as `examples/quickstart`: keep the runnable
+entrypoint at the example root and put agent construction, prompts, config and
+tools under `agent/`.

+└── schema.sql
+```
+
+Run one public fixture in dry-run / fake-model mode:
+
+```bash
+python examples/skills_code_review_agent/run_agent.py --fixture security_issue --dry-run --output-dir tmp/code_review_security --db-path tmp/code_review_security/review.sqlite3
+```
+
+Run all public fixtures:
+
+```bash
+python -m pytest tests/examples/test_skills_code_review_agent.py
+```
+
+Query the database by task id:
+
+```bash
+python examples/skills_code_review_agent/run_agent.py --db-path tmp/code_review_security/review.sqlite3 --query-task-id <task_id>
+```
+
+The CLI accepts:
+
+- `--diff-file`: unified diff or PR patch.
+- `--repo-path`: local git worktree, reviewed via `git diff`.
+- `--path-list-file`: paths to review inside `--repo-path`.
+- `--fixture`: fixture name under `fixtures/`.
+
+Outputs are always:
+
+- `review_report.json`
+- `review_report.md`
+- SQLite rows for task, sandbox runs, filter intercepts, findings, metrics and report.
+
+The deterministic CLI executes the bundled `skills/code-review` scripts directly so it can run without a model key. `agent/tools.py` also exposes `create_review_skill_tool_set()` for wiring the same Skill into a regular `LlmAgent`.
+`agent/agent.py` provides that optional `LlmAgent` wrapper, and `agent/config.py` reads the same `TRPC_AGENT_API_KEY`, `TRPC_AGENT_BASE_URL` and `TRPC_AGENT_MODEL_NAME` environment variables used by the quickstart examples. `run_agent.py` remains the acceptance-test entrypoint because it is deterministic and does not need external model credentials.
+
+## Runtime Modes
+
+Production mode is `--runtime container`, which runs skill scripts in a Docker workspace with network disabled and the same `skills/`, `work/` and `out/` layout used by the framework workspace tools. `--dry-run` and `--fake-model` use a deterministic local workspace fallback so the parsing, sandbox, Filter and database chain can be tested without model credentials.
+
+Sandbox execution has a timeout, output byte limit, environment allowlist and secret redaction. Timeouts and failures are recorded as sandbox runs and manual-review items; they do not crash the review.
+
+## Public Fixtures
+
+- `no_issue`: benign change with tests.
+- `security_issue`: `shell=True` and `eval`.
+- `async_resource_leak`: unscoped `aiohttp.ClientSession` and unobserved background task.
+- `db_lifecycle_issue`: unscoped DB connection and string-built SQL.
+- `missing_tests`: production change without tests.
+- `duplicate_finding`: repeated secret finding used to verify deduplication.
+- `sandbox_failure`: used by tests to force script failure while keeping the task alive.
+- `secret_redaction`: API key, token, password and bearer credential redaction.
+
+## 300-500 字方案设计
+
+本示例以 `examples/skills_code_review_agent` 形式交付，避免改动核心 SDK。`code-review` Skill 包含 `SKILL.md`、规则文档和两个脚本：`parse_diff.py` 负责抽取文件、hunk 与增删行统计，`static_rules.py` 负责在沙箱中产出高信号静态检查结果。Agent 入口支持 `--diff-file`、`--repo-path`、`--path-list-file` 和 `--fixture`，先解析 unified diff 得到变更文件、候选行号和上下文，再合并沙箱脚本与内置规则结果。dry-run / fake-model 模式不依赖真实模型 API Key，保证公开样本和 CI 中的链路可重复。
+
+沙箱由 `SandboxRunner` 封装。生产默认使用 `--runtime container`，Docker 运行时禁用网络；dry-run 只作为开发 fallback，在临时 workspace 中执行同一套 Skill 脚本。每个沙箱请求都先经过 `ReviewExecutionFilter`：禁止敏感路径、路径穿越、非白名单网络访问、超时或输出超预算请求；对 curl 管道、包安装、破坏性命令和提权命令标记 `needs_human_review`，并直接写入报告和数据库，不能继续执行。
+
+SQLite 默认 schema 包含 `review_task`、`sandbox_run`、`finding`、`filter_intercept`、`review_metric` 和 `review_report`，可通过 task id 查询完整任务、执行摘要、拦截记录、监控指标、findings 与最终报告。存储实现集中在 `ReviewStore`，后续可替换为其他 SQL 后端。去重以 `(file, line, category)` 为键，保留置信度和严重级别更高的结果；低置信度或测试缺失等弱信号进入 warnings / needs_human_review。脱敏覆盖输入 diff、沙箱 stdout/stderr、产物、findings、Markdown/JSON 报告和数据库行，避免 API Key、token、password、私钥等明文落盘。最终报告包含 findings 摘要、严重级别统计、人工复核项、Filter 拦截摘要、监控指标、沙箱执行摘要和可执行修复建议。

+# Code Review Report: sample-security-review
+
+Input: `fixture:security_issue`
+
+## Summary
+
+- Conclusion: High-risk issues found; block merge until fixes are applied.
+- Findings: 2
+- Warnings: 0
+- Needs human review: 1
+- Severity distribution: `{'high': 2, 'low': 1}`
+
+## Findings
+
+### HIGH security: subprocess uses shell=True
+
+- Location: `app/search.py:5`
+- Evidence: `return subprocess.check_output(cmd, shell=True)`
+- Recommendation: Pass an argument list with shell=False and validate any user-controlled arguments.
+- Confidence: `0.88`
+- Source: `rule:shell-injection`
+
+### HIGH security: Dynamic code execution introduced
+
+- Location: `app/search.py:8`
+- Evidence: `return eval(expr)`
+- Recommendation: Avoid eval/exec on runtime data; use a constrained parser or explicit dispatch table.
+- Confidence: `0.9`
+- Source: `rule:dangerous-exec`
+
+
+## Warnings
+
+No warnings.
+
+## Needs Human Review
+
+### LOW testing: Production code changed without tests
+
+- Location: `app/search.py:4`
+- Evidence: `app/search.py changed, but no test file was included in the diff.`
+- Recommendation: Add or update tests that cover the changed behavior before merging.
+- Confidence: `0.62`
+- Source: `rule:test-coverage`
+
+
+## Filter Intercepts
+
+- `needs_human_review` `script.high_risk_command`: command contains network, package installation, privilege or destructive operations
+
+## Monitoring
+
+- total_duration_ms: `231`
+- sandbox_duration_ms: `143`
+- tool_call_count: `3`
+- intercept_count: `1`
+- finding_count: `2`
+- warning_count: `0`
+- needs_human_review_count: `1`
+- severity_distribution: `{'high': 2, 'low': 1}`
+- exception_type_distribution: `{'FilterIntercept': 1}`
+- redaction_count: `0`
+- changed_file_count: `1`
+- changed_line_count: `5`
+
+## Sandbox Runs
+
+- `parse-diff` runtime=`dry-run-local` status=`succeeded` duration_ms=`73` timed_out=`False`
+- `static-rules` runtime=`dry-run-local` status=`succeeded` duration_ms=`70` timed_out=`False`
+- `high-risk-script-probe` runtime=`dry-run-local` status=`filtered` duration_ms=`0` timed_out=`False`
+
+## Fix Recommendations
+
+- app/search.py:5 - Pass an argument list with shell=False and validate any user-controlled arguments.
+- app/search.py:8 - Avoid eval/exec on runtime data; use a constrained parser or explicit dispatch table.
+- app/search.py:4 - Add or update tests that cover the changed behavior before merging.

+name: code-review
+description: Structured code review skill with diff parsing, static checks, sandbox execution policy, redaction and report generation.
+---
+
+# Code Review Skill
+
+Use this skill to review unified diffs, PR patches or local git changes. The skill is designed for a sandboxed workspace:
+
+1. Load the diff into `work/inputs/input.diff`.
+2. Run `scripts/parse_diff.py work/inputs/input.diff out/diff_summary.json`.
+3. Run `scripts/static_rules.py work/inputs/input.diff out/static_findings.json`.
+4. Merge deterministic rule findings with model review findings only after redaction and deduplication.
+5. Persist task, sandbox runs, filter intercepts, metrics, findings and final report.
+
+Tools:
+- skill_run
+
+## Review Contract
+
+Every finding must include:
+
+- `severity`: critical, high, medium, low or info.
+- `category`: security, async_error, async_resource, resource_leak, testing, sensitive_info, db_lifecycle or sandbox.
+- `file` and `line`: changed file path and candidate new-line number.
+- `title`, `evidence`, `recommendation`, `confidence`, `source`.
+
+Low-confidence items must be emitted as warnings or `needs_human_review`, not as high-confidence findings.
+
+## Safety Rules
+
+Do not run network, package installation, destructive filesystem, privilege escalation, SSH, Docker or curl-pipe-shell commands without an explicit Filter allow decision. Denied or `needs_human_review` commands must be recorded in the report and database instead of being executed.
+
+Only pass whitelisted environment variables into the sandbox. Redact API keys, tokens, passwords, private keys and bearer credentials before writing logs, reports or database rows.
+

+# Code Review Rules
+
+This skill ships deterministic checks that are intentionally explainable and easy to audit.
+
+## Covered Categories
+
+- Security risks: dynamic `eval` or `exec`, `subprocess(..., shell=True)`, string-built SQL, unsafe YAML loading and pickle deserialization.
+- Asynchronous errors: unscoped `aiohttp.ClientSession` and unobserved `asyncio.create_task`.
+- Resource leaks: `open()` without a context manager and predictable temporary files.
+- Testing gaps: production Python changes without a corresponding test diff.
+- Sensitive information leakage: API keys, tokens, passwords, private keys, bearer credentials and common provider key formats.
+- Database lifecycle: raw DB connections or ORM sessions created without scoped close, commit or rollback.
+
+## Noise Control
+
+The agent deduplicates on `(file, line, category)`. Findings below confidence 0.8 become warnings or manual-review items. The test-gap rule is advisory because a hidden test suite or generated tests can exist outside the patch.
+
