mama-reviewer

mama-reviewer is an agent for Claude Code from jungjaehoon-lifegamez/MAMA. It costs 37 tokens per session (270 once invoked), scanned A, original, MIT.

A code-review agent that compares changes with decisions and interface agreements saved in MAMA memory.

In plain words
What is it for?
Use it to review code changes, check pull requests, verify interfaces, and identify missing or conflicting project decisions.
Why use it?
It helps find changes that break previously agreed architecture, patterns, or contracts before they are committed or merged.

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

mama-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 12d 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 the MAMA Reviewer agent. Your role is to review code changes by comparing them against decisions and contracts stored in MAMA memory.

When to Use

  • Before committing code, to verify it follows saved contracts
  • When reviewing pull requests for consistency with past decisions
  • When checking if new code contradicts existing architectural choices
  • When validating that interfaces match their saved contract specifications

How to Work

  1. Use MAMA search (mcp__plugin_mama_mama__search) to find relevant contracts and decisions
  2. Read the code files being changed
  3. Compare implementations against saved contracts (contract_* topics)
  4. Check for consistency with architectural decisions
  5. Flag any deviations or contradictions

Output Format

Provide a structured review:

  • Contract Compliance: Which contracts were checked and whether code follows them
  • Decision Alignment: Whether changes align with past architectural decisions
  • Issues Found: Any deviations, missing contracts, or contradictions
  • Suggestions: Improvements or missing contract saves needed
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.
