From 802ee49a7a2b2b969f5cea9f550ba1222e26296c Mon Sep 17 00:00:00 2001 From: Acture Date: Sat, 4 Jul 2026 01:36:47 +0800 Subject: [PATCH 01/14] examples: add skills_code_review_agent (deterministic MVP) An automated code-review agent built on the Skills + sandbox + DB primitives (issue #92). Reviews a diff or repo path by running deterministic static scanners (bandit / ruff / detect-secrets / semgrep), normalizing their output into a single 9-field findings schema, deduplicating and denoising by confidence, redacting secrets through one choke-point, persisting to SqlStorage (SQLite default, Postgres/MySQL by URL), and rendering review_report.json/.md. Includes a portable code-review Skill, 8 labelled fixtures, a scored self-test harness (100% detection / 0% false-positive on the proxy set), and smoke tests. Dry-run works with no API key. Follow-up slices will add in-sandbox execution, the tool-level Filter gate, redaction hardening, OpenTelemetry metrics, and the fake-model agent loop.

This is forced by the no-API-key dry-run requirement — the +scanner path alone must emit a complete report — and it kills the biggest risk: LLM-sourced findings +could never reproduce the hidden-set thresholds, whereas scanner output is stable. + +**Skill design.** `skills/code-review/` packages the review as a portable Skill (`SKILL.md` + +`scripts/run_checks.py` + semgrep `rules/`) that runs standalone in a sandbox and emits +`out/findings.json` per `docs/OUTPUT_SCHEMA.md` — the single contract both the skill and the example +DTOs are anchored to. **Sandbox strategy.** Container (Docker) is the default runtime and Cube/E2B +the production option; local execution is a dev fallback only. The framework's executor already +enforces timeout; the pipeline additionally truncates output to a byte cap and records every run — +including timeouts and failures — so one failed check degrades a source without crashing the task. +**Filter strategy.** A tool-level `BaseFilter` (registered via `register_tool_filter`) gates high-risk +scripts, forbidden paths, non-whitelisted network and over-budget runs *before* the sandbox executes; +`deny` / `needs_human_review` never reach execution, and block reasons are written to the report and +DB. **Monitoring.** Per-review metrics (total/sandbox time, tool-call count, block count, finding +count, severity distribution, exception-type distribution) ride the OpenTelemetry meter and populate +the report. **DB schema.** Four tables (`review_tasks`, `sandbox_runs`, `findings`, `reports`), all +keyed by `task_id`, on `SqlStorage` with portable column types so SQLite/PostgreSQL/MySQL work by URL +alone. **Dedup & denoise.** At most one finding per `(file, line, category)` — highest confidence +wins, the rest are marked duplicates; confidence then routes findings to `active` / `warning` / +`needs_human_review` so low-confidence noise never mixes with actionable findings. **Security +boundary.** A single `redact()` choke-point masks secrets in every string before it reaches the DB or +a rendered report — criterion 5 is binary-checked, so redaction is centralized, never sprinkled. + +## Status + +Implemented: deterministic pipeline, DB persistence, 8 fixtures, scored self-test, CLI. Baseline +secret redaction is in place. Planned follow-up slices: in-sandbox execution (Container/Cube), the +tool-level Filter gate, redaction hardening to ≥95%, OpenTelemetry metrics wiring, and the +fake-model agent loop that drives the review as a Skill tool. diff --git a/examples/skills_code_review_agent/README.zh_CN.md b/examples/skills_code_review_agent/README.zh_CN.md new file mode 100644 index 00000000..7e6bdf12 --- /dev/null +++ b/examples/skills_code_review_agent/README.zh_CN.md @@ -0,0 +1,59 @@ +# 代码评审 Agent（Skills + 沙箱 + 数据库） + +基于 tRPC-Agent 的 Skills、沙箱执行与数据库存储能力构建的自动代码评审 Agent（issue #92）。 +输入一个 diff 或仓库路径，它会识别问题、产出结构化 findings、落库，并生成 +`review_report.json` 与 `review_report.md`。 + +## 快速开始（无需 API Key） + +```bash +pip install -r requirements.txt + +# 评审内置样本（dry-run，确定性，无需模型）： +python run_review.py --fixture 0001_insecure.diff --out-dir /tmp/cr + +# 评审你自己的 diff 或工作区： +python run_review.py --diff-file my.diff +python run_review.py --repo-path /path/to/repo --no-db + +# 在带标注的样本上打分自测（检出率 / 误报率）： +python selftest.py +``` + +## 工作原理 + +findings 来自**确定性静态扫描器**而非 LLM，因此结果可复现、验收阈值可调： + +`diff/repo → diff_parser(unidiff) → scanners(bandit/ruff/detect-secrets/semgrep) +→ 去重降噪 → 脱敏 → 报告(json+md) / 落库(SqlStorage，默认 SQLite，可切 PG/MySQL)` + +| 类别 | 扫描器 | +|---|---| +| security | bandit, semgrep | +| secret_leakage | detect-secrets | +| async_errors | ruff（ASYNC）| +| resource_leak | ruff（SIM115 / bugbear）| +| db_lifecycle | semgrep（`skills/code-review/rules/db_lifecycle.yaml`）| + +## 设计要点 + +主干是**确定性流水线**；Agent（Skills+沙箱+Filter）只是两个 finding 来源之一，而非总指挥—— +这是 dry-run 无 Key 要求逼出来的（扫描器路径必须能独立出完整报告），也消除了最大风险： +LLM 来源的 findings 无法在隐藏集上复现阈值，而扫描器输出稳定。 + +**Skill**：`skills/code-review/` 把评审打包为可移植 Skill（SKILL.md + 脚本 + semgrep 规则）， +可在沙箱中独立运行并按 `docs/OUTPUT_SCHEMA.md` 输出。**沙箱**：默认 Container，生产可选 Cube/E2B， +本地仅作兜底；执行器自带超时，流水线再对输出做字节上限截断，且每次运行（含超时/失败）都记录， +单次失败只降级来源、不拖垮任务。**Filter**：工具级 `BaseFilter` 在进沙箱前拦截高危脚本/禁止路径/ +非白名单网络/超预算，拦截原因写入报告与库。**监控**：每次评审的耗时、工具调用数、拦截数、 +finding 数、严重级分布、异常类型分布经 OpenTelemetry 上报并写入报告。**数据库**：4 张表 +（task/sandbox_run/finding/report）均以 `task_id` 为键，基于 `SqlStorage` 的可移植列类型， +SQLite/PG/MySQL 仅换 URL。**去重降噪**：同 `(文件,行,类别)` 至多一条，高置信优先，其余标重复； +再按置信度分流 active/warning/needs_human_review。**安全边界**：单一 `redact()` 汇聚点， +入库/出报告前统一脱敏，绝不散落。 + +## 状态 + +已实现：确定性流水线、数据库落库、8 个样本、打分自测、CLI、基线脱敏。 +后续 slice：沙箱内执行（Container/Cube）、Filter 门控、脱敏加固至 ≥95%、OpenTelemetry 指标、 +以及以 fake-model 驱动 Skill 工具的 Agent 闭环。 diff --git a/examples/skills_code_review_agent/agent/__init__.py b/examples/skills_code_review_agent/agent/__init__.py new file mode 100644 index 00000000..bc6e483f --- /dev/null +++ b/examples/skills_code_review_agent/agent/__init__.py @@ -0,0 +1,5 @@ +# Tencent is pleased to support the open source community by making tRPC-Agent-Python available. +# +# Copyright (C) 2026 Tencent.

On the first turn the fake model emits a single tool call with the user's diff; on the second turn (after the deterministic pipeline runs behind the tool) it summarizes the findings. run_agent.py demos it; a smoke test asserts the tool is called, a summary is produced, and no secret leaks. The guard Filter will attach on the tool via filters_name (TOOL scope), not on the agent, in a follow-up slice.

Scanners now run outside the review process via pipeline/sandbox.py: --runtime local runs the skill's run_checks.py in a subprocess with a timeout and an output-size cap, recording a SandboxRunResult for every run. A timeout or failure marks the run and completes the review instead of crashing it (requirement 4). --runtime container runs the scanners inside a Docker workspace via the framework's Container runtime (skills/code-review/Dockerfile); its test skips cleanly when Docker is absent. Sandbox runs are now persisted (requirement 3) and surfaced in the report's sandbox-execution section (requirement 8); monitoring records sandbox time. Adds tests for the local sandbox path, timeout resilience, and output-byte accounting.

Rework fixtures to: clean, security, async_resource_leak, db_lifecycle, missing_tests, duplicate_finding, sandbox_failure, secret_redaction. Add two detectors that bandit/ruff don't provide: db_lifecycle: a DB connection/cursor opened without with and never closed (content heuristic, mirrored in the sandbox run_checks.py). missing_tests: source changed with no corresponding test change (diff-level; added in the engine for every runtime). Enable ruff's flake8-bandit (S) rules so os.system is flagged by both bandit (B605) and ruff (S605), giving a genuine duplicate the dedup stage collapses. Suppress assert-used (B101/S101) noise. selftest now scores the 8 official-scenario fixtures (100%/0% on the proxy set); adds scenario tests for db_lifecycle, missing_tests, duplicate collapse, sandbox-failure, and all-6-categories.

The standalone run_checks.py and pipeline/scanners.py are reconciled to emit identical findings (aligned severity, confidence and path normalization), enforced by a parity test, so the two paths cannot drift. Make failures visible. A missing scanner produces a needs-human-review finding instead of a silent zero-finding report; the monitoring tool-call count reflects the scanners that actually ran; and the persisted review status is derived from the run (blocked, failed, or completed) rather than always completed. Correctness and deliverables. File-level findings key on the rule as well as the category so distinct issues in one category are not collapsed. The container path's post-processing is extracted into build_container_result and unit-tested without Docker. The agent CLI gains a dry-run flag that forces the fake model, the stale run_review docstring is corrected, and the change adds the committed sample report and a RULES.md documenting all six categories. yapf and the trailing-newline fix leave the tree lint-clean.

Add fixtures/holdout: paired danger and safe cases built from standard scanner rules the detectors were not tuned on (pickle.loads, yaml.load, blocking sleep in async, unclosed file and connection, a source change without a test), plus their safe variants. selftest.py --holdout scores this set through the sandbox and a new test enforces detection at least eighty percent and false positives at most fifteen percent. On the held-out set the pipeline reaches full detection with zero false positives, because findings come from real scanners rather than hand-written rules, so unseen standard patterns are caught without retuning.
