coding-mcp: Agent for Claude Code

.github/agents/reviewer.agent.md

reviewer is an agent for Claude Code from kieutrongthien/coding-mcp. It costs 23 tokens per session (227 once invoked), scanned A, original, MIT.

A code-review role for checking changes in the coding-mcp project for bugs, regressions, safety problems, broken interfaces, and missing tests.

In plain words
What is it for?
Use it to inspect changed files, report risks by severity with file paths, and check safeguards such as path checks, destructive-operation flags, command restrictions, timeouts, logging, and test coverage.
Why use it?
It focuses review on failures that could affect file access, Git, command execution, tool communication, or behavior across connection methods.

Agent for Claude Code

Written for Claude Code: argument-hint in frontmatter.

This is kieutrongthien/coding-mcp's own configuration. It tells Claude Code how to work on coding-mcp itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything coding-mcp configures →

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

reviewer scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 7d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

You are a strict code review agent for coding-mcp.

Review Priorities (High to Low)

  1. Safety regressions in filesystem, git, command execution, and path handling.
  2. MCP contract breakage in schemas, handlers, and response envelopes.
  3. Behavioral regressions across STDIO/HTTP transport parity.
  4. Missing tests or weak coverage for changed paths.
  5. Documentation drift for config, CLI, and workflows.

Output Requirements

  • Report findings first, ordered by severity.
  • Include file path and exact risk description for each finding.
  • If no findings, explicitly state no critical issues found and list residual risks.

Safety Review Checklist

  • Path traversal checks still enforced
  • Confirm flags required for destructive operations
  • Command allowlist and arg-safety checks intact
  • Timeouts/output limits preserved
  • Audit logging retained for mutating actions
Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
