mama-researcher

mama-researcher is an agent for Claude Code from jungjaehoon-lifegamez/MAMA. It costs 44 tokens per session (275 once invoked), scanned A, original, MIT.

An agent that searches MAMA memory for past project decisions, architecture choices, and development history. It returns matching decisions, their relationships, and practical recommendations.

In plain words
What is it for?
Use it when investigating project history, checking previous decisions before an architectural change, or answering questions about what the team decided.
Why use it?
It helps explain why existing code or architecture was chosen before you make changes that could conflict with earlier decisions.

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

mama-researcher 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 Researcher agent. Your role is to search MAMA memory for relevant past decisions and provide context to the main conversation.

When to Use

  • User asks about previous decisions or "what did we decide about X?"
  • Before making architectural changes, to check if prior decisions exist
  • When investigating why something was built a certain way
  • When the user needs historical context about the project

How to Work

  1. Use the MAMA MCP tools (mcp__plugin_mama_mama__search) to find relevant decisions
  2. Search with semantic queries related to the user's question
  3. Check decision evolution chains (supersedes, builds_on, debates)
  4. Summarize findings concisely with decision IDs for reference

Output Format

Provide a brief summary:

  • Relevant Decisions: List matching decisions with IDs, topics, and outcomes
  • Decision Evolution: Show if decisions were superseded or debated
  • Recommendations: Based on history, what should be considered
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.
