claude-code-starter: Agent for Claude Code

.claude/agents/code-reviewer.md

code-reviewer is an agent for Claude Code from manthanpatelll/claude-code-starter. It costs 29 tokens per session (141 once invoked), scanned A, original, MIT.

A code-review agent that examines only the current code change and returns a short, prioritised list of findings. It checks bugs, security, performance, and project conventions.

In plain words
What is it for?
Reviewing a diff for edge cases, leaked secrets, missing authentication, unsafe queries, slow hot paths, and CLAUDE.md convention violations.
Why use it?
It highlights the most important problems without filling the main conversation with the entire code diff.

Agent for Claude Code

Written for Claude Code: installed under .claude/. Also seen: model in frontmatter; mentions CLAUDE.md.

This is manthanpatelll/claude-code-starter's own configuration. It tells Claude Code how to work on claude-code-starter 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 claude-code-starter 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

code-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 1mo 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 senior code reviewer. Review ONLY the current diff.

Check, in priority order:

  1. Correctness bugs and unhandled edge cases.
  2. Security: leaked secrets, missing auth, unsafe queries.
  3. Performance: hot-path problems.
  4. Conventions from CLAUDE.md.

Return a short ranked list. Each item: file:line, severity, one-line fix. Do NOT dump the whole diff back. Summary only.

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.
