From 2bf3f067ab3a81e73d587030600ad32046ea2c1b Mon Sep 17 00:00:00 2001 From: xiyue1753 Date: Thu, 30 Jul 2026 20:53:01 +0800 Subject: [PATCH 1/3] examples: add skills-based code review agent example (#92) Add a skills_code_review_agent example under examples/ that composes Skill loading, deterministic rule engine (10 rules covering security, resource leaks, error handling, and testing), Docker container/local subprocess sandbox with timeout/output limits, three-level Filter governance (deny/ask/needs_human_review), SQLite persistence (6 tables), and JSON/Markdown dual-format structured reports. Supports --diff-file, --repo-path, and --files input modes. Agent mode via LlmAgent + SkillToolSet with FakeModel (no API key required) or real LLM (OpenAI-compatible). Includes 40 unit tests and 8 diff fixtures covering clean code, security issues, resource leaks, DB lifecycle, missing tests, deduplication, sandbox failure, and sensitive info. Fixes #92 RELEASE NOTES: New code review agent example integrates Skills, sandbox execution, SQLite persistence, and three-level Filter governance for automated Python diff review.

Review Agent + +## Architecture + +The agent follows a pipeline architecture with five stages: + +``` +Input(diff) -> Parser -> Rules -> Dedup+Redact -> Storage+Report +``` + +**Skill Design**: The code-review skill provides 4 rule categories (security, resource leaks, error handling, testing) and two sandbox scripts for independent execution. The ten deterministic regex rules guarantee baseline detection rates without LLM dependency, enabling dry-run mode that completes in under one second. Rules are confidence-weighted: critical findings default to 0.95 confidence while testing rules at 0.80 route to human-review warnings. + +**Sandbox Isolation**: Script execution uses local subprocess executor with timeout control (30s default) and output size limits (100KB). Container executor interface is reserved for production deployment where network isolation and read-only mounts are required. Execution failures are captured as partial results without aborting the review pipeline. + +**Filter Strategy**: Three-level pre-execution governance classifies commands into deny (system destruction like rm -rf, mkfs, fork bombs — blocked from sandbox entirely), ask (privilege escalation like sudo, chown — requires user confirmation), and needs_human_review (dependency installs like pip install, network calls like curl — flagged for human judgment). Denied findings are recorded in filter_decision table and excluded from the report. Review-flagged items remain present but with filter_action metadata for auditor visibility. + +**Database Schema**: Six SQLite tables connected by task_id foreign keys form a complete audit trail: review_task for job metadata, finding for structured issues, sandbox_run for execution records, filter_decision for governance decisions, monitoring for performance metrics with JSON severity distribution, and report for generated outputs. The get_task_details method aggregates all records for a single task. + +**Dedup and Noise Reduction**: Findings are deduplicated using (file, line, category) triplets as composite keys. Items with confidence below 0.85 are routed to warnings for human review rather than mixed with high-confidence findings. Testing violations and other inherently uncertain categories automatically fall into the warning bucket. + +**Security Boundaries**: Sensitive data including API keys, access tokens, bearer credentials, JWT tokens, and passwords is redacted at multiple boundaries: finding evidence before database writes, sandbox stdout/stderr before persistence, and report content before output. Redaction combines seven regex pattern families with Shannon entropy detection for identifying unknown high-entropy credential strings. diff --git a/examples/skills_code_review_agent/README.md b/examples/skills_code_review_agent/README.md new file mode 100644 index 000000000..679bedc05 --- /dev/null +++ b/examples/skills_code_review_agent/README.md @@ -0,0 +1,69 @@ +# Skills Code Review Agent + +Automated code review agent for Python projects using Skills, deterministic rules, sandbox execution, and SQLite persistence. + +## Quick Start + +```bash +cd examples/skills_code_review_agent + +# Sync mode: review a diff file or git repo +python run_review.py --diff-file fixtures/security.diff +python run_review.py --repo-path /path/to/your/repo + +# Agent mode: LlmAgent + SkillToolSet + FakeModel (no API key) +python run_review.py --diff-file fixtures/security.diff --agent + +# Agent mode with real LLM enhancement +export TRPC_AGENT_API_KEY=your_key +export TRPC_AGENT_BASE_URL=https://api.openai.com/v1 +export TRPC_AGENT_MODEL_NAME=gpt-4o-mini +python run_review.py --diff-file fixtures/security.diff --agent --model gpt-4o-mini + +# Run all tests +python -m pytest test_code_review_agent.py -v +``` + +## Modes + +| Mode | Flag | Driver | Skill Loading | Sandbox | Filter | +|------|------|--------|---------------|---------|--------| +| Sync (default) | `--diff-file` | `main()` function pipeline | not used | `SandboxRunner.run_script()` | `check_dangerous()` | +| Agent | `--agent` | `LlmAgent` + `Runner.run_async()` | `skill_load`/`skill_run` | `SkillRunTool` + `LocalWorkspaceRuntime` | `CodeReviewSafetyFilter(BaseFilter)` | + +## Review Categories + +| Category | Severity | Examples | +|----------|----------|----------| +| Security | critical | Hardcoded secrets, shell=True, eval(), pickle.loads | +| Resource Leak | high | open() without with, unclosed HTTP sessions, DB connections | +| Error Handling | high | Swallowed exceptions, bare except clauses | +| Testing | medium | New functions/classes without test coverage | + +## Test Fixtures + +| Fixture | Description | Expected | +|---------|-------------|----------| +| clean.diff | Trivial helper function | 0 findings | +| security.diff | Hardcoded secrets, eval, pickle, shell=True | >=3 security findings | +| resource_leak.diff | open() without with, unclosed DB connection | >=2 resource findings | +| db_lifecycle.diff | pymysql.connect without context manager | >=1 DB lifecycle finding | +| missing_test.diff | New functions without test file | >=1 testing warning | +| duplicate.diff | Multiple issues on same file | Proper dedup | +| sandbox_fail.diff | Long-running script | No crash, partial results | +| sensitive_info.diff | API keys, tokens, passwords | All secrets redacted | + +## Output + +- `output//review_report.json` — JSON structured report +- `output//review_report.md` — Markdown human-readable report + +## Architecture + +See [DESIGN.md](DESIGN.md) for architecture details. + +## Requirements + +- Python 3.10+ +- trpc-agent-py >= 1.1.0 +- pytest (for tests only) 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 000000000..e69de29bb diff --git a/examples/skills_code_review_agent/agent/dedup.py b/examples/skills_code_review_agent/agent/dedup.py new file mode 100644 index 000000000..550f6633c --- /dev/null +++ b/examples/skills_code_review_agent/agent/dedup.py @@ -0,0 +1,37 @@ +# Tencent is pleased to support the open source community by making trpc-agent-python available. +# Copyright (C) 2025 Tencent.

The get_task_details method aggregates all records for a single task. **Dedup and Noise Reduction**: Findings are deduplicated using (file, line, category) triplets as composite keys. Items with confidence below 0.85 are routed to warnings for human review rather than mixed with high-confidence findings. Testing violations and other inherently uncertain categories automatically fall into the warning bucket. diff --git a/examples/skills_code_review_agent/README.md b/examples/skills_code_review_agent/README.md index 679bedc05..56f5a7780 100644 --- a/examples/skills_code_review_agent/README.md +++ b/examples/skills_code_review_agent/README.md @@ -31,6 +31,18 @@ python -m pytest test_code_review_agent.py -v | Sync (default) | `--diff-file` | `main()` function pipeline | not used | `SandboxRunner.run_script()` | `check_dangerous()` | | Agent | `--agent` | `LlmAgent` + `Runner.run_async()` | `skill_load`/`skill_run` | `SkillRunTool` + `LocalWorkspaceRuntime` | `CodeReviewSafetyFilter(BaseFilter)` | +## Filter Governance (three-level semantics) + +Commands found in tool calls / finding evidence are classified into three levels: + +| Level | Examples | Behavior | +|-------|----------|----------| +| `deny` | `rm -rf /`, `mkfs`, fork bomb | Hard-blocked (`is_continue=False`), never executed, decision recorded | +| `ask` | `sudo`, `iptables`, `chown` | Interactive confirmation prompt (`y/N`); approved → executes and recorded as `approved`, rejected → blocked and recorded as `denied (no human confirmation)`.
