原型，目标是展示如何把 +Skill、输入解析、治理策略、沙箱适配、结构化 findings、SQLite 持久化和报告输出 +组合成一个可验证闭环。它不修改 `trpc_agent_sdk/`，不新增 SDK 公共 API，也不把 +代码评审能力抽象成框架级模块。所有实现都位于 `examples/skills_code_review_agent/` +内，便于独立运行、测试和后续演进。 + +默认执行路径是 dry-run，不依赖真实模型 API Key、Docker、Cube 或外部服务。 +`container` 和 `cube` runtime 作为可选真实执行后端：环境可用时通过 SDK workspace runtime +执行规则脚本，环境不可用或未配置时记录为需要人工复核。 +`local-dev` 没有隔离能力，因此必须显式传入 `--allow-local` 才能执行。 + +## 总体数据流 + +一次 review 从 CLI 开始： + +```text +run_review.py + -> input_parser + -> skill_loader + -> sandbox.run_rule_script + -> review_rules + -> governance decision + -> report routing and dedupe + -> SQLite store + -> JSON / Markdown report +``` + +CLI 只负责参数解析、基本校验和打印结果；核心编排在 `agent/pipeline.py` 中完成。 +pipeline 会把 `--diff-file`、`--repo-path` 或 `--fixture` 统一解析为 +`InputSummary`，加载本地 `code-review` Skill manifest，执行规则脚本，收集 +`FilterEvent` 与 `SandboxRun`，再生成 `ReviewReport` 并保存到 SQLite。 + +## Skill 设计 + +### 目录结构 + +`skills/code-review/` 是一个完整的本地 Skill 包： + +```text +skills/code-review/ + SKILL.md + README.md + rules/ + security.md + async-resource.md + testing-db.md + runtime.md + scripts/ + rule_runner.py +``` + +`SKILL.md` 描述输入、输出、规则文档、脚本入口和安全边界。`skill_loader.py` +负责读取 front matter、校验规则和脚本路径、计算 digest，并输出 example-local +`SkillManifest`。这里没有调用 SDK 的 `SkillToolSet`，原因是当前示例要在无模型、 +无真实 Agent session 的环境中稳定测试；但目录组织和 Skill 概念仍与 SDK Skill +体系保持一致。 + +### 规则脚本 + +`scripts/rule_runner.py` 是沙箱或 dry-run 中执行的命令入口。它接收规范化后的 +`InputSummary` JSON 和 Skill manifest JSON，验证 schema 必要字段，然后调用 +`agent.review_rules.run_review_rules()` 生成 deterministic findings。脚本支持直接执行 +时的 import fallback，确保从示例目录运行 CLI 不需要安装额外包。 + +## 输入解析设计 + +`agent/input_parser.py` 把三类输入统一转换成 `InputSummary`： + +- `--diff-file`：读取 UTF-8 unified diff。 +- `--repo-path`：执行 `git diff`，并把 untracked 文本文件转换为 added-file diff。 +- `--fixture`：读取 `fixtures/.diff` 或显式 fixture 路径。 + +解析结果保留 file、old_path、status、hunk、context line、added/deleted line、 +candidate line 和 binary marker。解析器对 malformed hunk 和 binary patch 采取 +容错策略：记录 diagnostics，不让整个 review 崩溃。后续规则只扫描 added lines， +因此 candidate line 是 finding 定位的主要来源。 + +## Finding 与规则设计 + +核心输出模型是 `Finding`，字段覆盖： + +- `severity` +- `category` +- `file` +- `line` +- `title` +- `evidence` +- `recommendation` +- `confidence` +- `source` +- `fingerprint` + +规则引擎当前覆盖 hard-coded secret、`eval` / `exec` / `shell=True`、async client +生命周期、文件句柄生命周期、数据库连接生命周期和测试缺失。规则优先分析新增行， +避免对未改动上下文产生过多噪声。secret 规则支持已脱敏输入中的 +`[REDACTED]` assignment 形态，这保证“落盘前脱敏”和“规则仍可检出 secret 类型” +两个安全目标不会互相冲突。 + +fingerprint 使用 category、file、line、title 和 redacted evidence 生成，供报告层和 +SQLite 去重使用。低置信度 finding 不进入主 findings，而是进入 warnings。 + +## Governance 与 Sandbox 设计 + +`agent/governance.py` 实现 example-local 执行治理模型。它不是 SDK Filter 扩展， +而是把 Filter 概念落成可测试的 `FilterEvent`： + +- `dry-run` 普通规则脚本允许执行。 +- `local-dev` 未显式 `--allow-local` 时拒绝。 +- `container` / `cube` 可用时进入 SDK workspace runtime；不可用或未配置时记录为 + `needs_human_review`。 +- 高风险命令、网络命令、禁止路径、timeout 超预算、output limit 超预算会被拒绝或 + 进入人工复核。 + +`agent/sandbox.py` 是统一执行入口，负责治理后的 runtime 分发、dry-run、本地 fallback 和 +结果落盘。`agent/sandbox_workspace.py` 承接可选 SDK workspace runtime 适配，负责 +container/cube 的 lazy 探测、最小 bundle 上传、远端 `rule_runner.py` 执行和 output spec +收集。任何 sandbox 失败都会转换成 `SandboxRun` 和诊断结果，不抛到 CLI 顶层导致整次 +review 崩溃。 + +Container 默认使用 `python:3-slim` 并关闭网络；Cube 只从环境变量读取 +`CUBE_TEMPLATE_ID`、`E2B_API_URL` 和 `E2B_API_KEY`，避免把凭证放进 CLI 参数、报告或 +数据库。两类远端后端都只 stage `models.py`、`review_rules.py`、`sanitizer.py`、 +`rule_runner.py`、脱敏后的输入和 manifest，不上传完整仓库。 + +## 安全边界 + +安全边界分为四层： + +1. 输入解析只保存 summary 和 diff hash，不把完整原始 diff 写入 SQLite。 +2. 治理层在执行前检查 runtime、路径、命令、网络、环境变量白名单和预算。 +3. sandbox 层执行 timeout 控制、stdout/stderr 捕获和 output size 截断。 +4. sanitizer 在 findings、filter events、sandbox output、report 和 store 写入前脱敏。 + +脱敏覆盖 Bearer token、API key、secret/token/password assignment、private key block +和常见连接串密码。需要注意，静态治理和脱敏不是完整 sandbox；真正的生产隔离仍应由 +Container、Cube 或等价受控 runtime 提供。 + +## SQLite 持久化设计 + +`agent/store.py` 使用标准库 `sqlite3`，避免给 example 引入 ORM 复杂度。它同时暴露最小 +store protocol 和 factory 注入点；SQLite 是默认实现，pipeline 可注入其他 SQL 后端而不改变 +CLI 或报告契约。最小 schema 包括： + +- `review_task` +- `input_diff` +- `finding` +- `filter_event` +- `sandbox_run` +- `report` +- `review_metrics` + +数据库保存 `InputSummary` JSON 和 diff SHA-256，而不是完整 raw diff。`review_metrics` +独立保存已有 `ReviewMetrics` 的计数和分布字段，便于不解析 report JSON 也能查询监控摘要。finding 表按 +`task_id + fingerprint + route` 去重，route 区分主 findings、warnings 和 +needs human review。查询 helper 支持按 task id 读取 task、input summary、finding、 +filter event、sandbox run 和 report。 + +## 报告与降噪设计 + +`agent/report.py` 负责去重、路由和渲染： + +- `dedupe_findings()` 基于 fingerprint 去重。 +- `route_findings()` 将低置信度问题放入 warnings。 +- governance 或 sandbox 不确定性会合成 `GOVERNANCE` 或 `SANDBOX` 类型的人工复核项。 +- `build_review_report()` 汇总 metrics、severity/category 分布、异常分布和结论。 +- `write_review_report()` 输出 JSON 和 Markdown。 + +报告结论根据高危 finding、人工复核项、warning 数量决定。Markdown 保持简单可读， +不引入模板引擎。 + +## 监控与审计字段 + +`ReviewMetrics` 记录： + +- 总耗时 +- sandbox 耗时 +- tool call 数 +- interception 数 +- finding / warning / human-review 数 +- severity 分布 +- category 分布 +- exception 分布 + +这些字段用于展示每次 review 的风险和执行状态，也为后续 Evaluation、回放或优化闭环 +保留基础数据。 + +## 测试策略 + +测试只关注业务代码行为，不验证 README 或 sample output。8 条公开 fixture 位于 +`fixtures/`，由端到端业务测试驱动，覆盖： + +- clean diff +- security issue +- async leak +- DB lifecycle +- missing tests +- duplicate finding +- sandbox failure +- secret redaction + +其余测试覆盖 parser、Skill loader、rule runner contract、governance、sandbox、 +pipeline、store、report 和 sanitizer。质量门禁测试用公开 deterministic corpus 固定高危召回、 +高置信误报和脱敏率代理指标。所有测试默认不依赖真实模型、Docker 或 Cube；真实 runtime 成功路径 +通过 fake workspace runtime 覆盖。 + +## 已知边界 + +- 当前没有真实 LLM planner/executor 调用。 +- 当前没有 SDK Filter 注册或 SDK CodeExecutor 扩展。 +- `container` / `cube` 真实后端依赖本机 Docker 或 Cube/E2B 配置；默认测试环境使用 fake 或 + unavailable 分支，不要求外部服务。 +- 规则是启发式 deterministic 检查，目标是可测试原型，不是完整静态分析器。 +- SQLite schema 是 example-local v1，当前不提供 migration 机制。 diff --git a/examples/skills_code_review_agent/README.md b/examples/skills_code_review_agent/README.md new
