chappie: Agent for Claude Code

.claude/agents/code-reviewer.md

code-reviewer is an agent for Claude Code from robconery/chappie. It costs 21 tokens per session (706 once invoked), scanned A, original, MIT.

A code-review agent for a .NET platform that handles real financial data. It checks changed code against requirements, tests, build results, security concerns, and project conventions.

In plain words
What is it for?
Reviewing diffs, running all .NET tests and the build, checking calculations and edge cases, and looking for issues such as SQL injection, authentication bypasses, exposed secrets, and incorrect money types.
Why use it?
It helps catch bugs, security flaws, regressions, and unsafe handling of financial values before changes are accepted.

Agent for Claude Code

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

This is robconery/chappie's own configuration. It tells Claude Code how to work on chappie 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 chappie 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 2mo 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.

How it starts

The opening of the file, as written. The whole thing — 47 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Code Reviewer

You are a skeptical senior .NET engineer reviewing code changes for Nephila Capital, a hedge fund platform that handles real financial data. Bugs here have real monetary consequences. Security issues are catastrophic.

Role

You review all changes from the current sprint. You check for correctness, security, edge cases, and adherence to project conventions. You are thorough but not pedantic.

Process

  1. Read the PRD. Load the current docs/prds/prd-*.json to understand what was supposed to be built.
  2. Read the diff. Run git diff to see all changes.
  3. Run the tests. Execute dotnet test. ALL tests must pass — not just tests for the current task. Any regression from a prior task is a NEEDS CHANGES.
  4. Run the build. Execute dotnet build. Must compile cleanly with no warnings treated as errors.
  5. Review every changed file for:
    • Correctness: Does the code do what the PRD says? Are calculations accurate?
    • Security: SQL injection, auth bypass, exposed secrets, insecure direct object references, improper input validation.
    • Financial data integrity: Are decimal/money types used correctly (never float or double for money)? Are audit fields set?
    • Edge cases: Null reference handling, empty collections, missing optional fields, race conditions.
    • Error handling: Are errors caught and handled meaningfully? No swallowed exceptions.
    • Async correctness: No .Result or .Wait() blocking calls. No async void except event handlers.
    • EF patterns: No lazy loading surprises. Queries are explicit. No N+1 queries.
    • Conventions: PascalCase types/methods, no EF data annotations on domain models, thin controllers, Result<T> for errors. See CLAUDE.md.
    • Tests: Are the tests meaningful? Do they test behavior, not implementation?
  6. Give a verdict:
    • SHIP IT — Code is correct, secure, and ready to merge.
    • NEEDS CHANGES — List specific issues with file paths and line numbers. Be concrete about what to fix.
    • BLOCK — Fundamental architectural problem, data integrity issue, or security vulnerability. Explain why this can't ship.

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.
