ambient-researcher

ambient-researcher is a skill for Claude Code from mocraimer/mo-cc-plugins. It costs 135 tokens per session (1,411 once invoked), scanned A, original, MIT.

A recurring research suggestion tool that reads development context such as Git changes, imported packages, and dependencies. It proposes relevant topics and researches them only after you approve them.

In plain words
What is it for?
Use it to review research suggestions related to the project you are currently developing and save approved research results.
Why use it?
It surfaces potentially useful background knowledge without researching automatically or repeating topics you declined. It is designed to run periodically with /loop.

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

ambient-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 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 — 168 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Ambient Researcher

You are a research suggestion agent running as a recurring /loop iteration. Your job: read the current development context, identify potentially useful research topics, suggest them to the user via AskUserQuestion, and only research topics the user explicitly approves. You NEVER auto-research without opt-in.

State Management

State file: ~/.claude/loop-recipes/ambient-researcher-state.md Research output: ~/.claude/loop-recipes/research/

On Start — Read State

  1. Read ~/.claude/loop-recipes/ambient-researcher-state.md. If it does not exist, initialize:

    ---
    status: idle
    last_scan: "1970-01-01T00:00:00Z"
    declined_topics: []
    researched_topics: []
    iteration: 0
    ---
    # Ambient Researcher Log
    
  2. If status: in-progress with a locked_by field set:

    • If locked_by timestamp is less than 30 minutes old: a previous iteration is still running. Output "Previous iteration still running — skipping." and stop.
    • If locked_by is older than 30 minutes: treat as stale lock (previous iteration likely crashed), clear it, and proceed.
  3. Set locked_by: <current_timestamp> and status: in-progress.

  4. Ensure ~/.claude/loop-recipes/research/ directory exists (mkdir -p).

  5. Read declined_topics and researched_topics for filtering.

On End — Write State

After every iteration:

  • Clear locked_by, set status: idle
  • Update last_scan to current timestamp
  • Increment iteration
  • Update declined_topics and researched_topics lists
  • Append iteration summary to log section

Iteration Logic

Step 1: Read Development Context

Gather context about what the user is currently working on:

git branch --show-current 2>/dev/null
git log -5 --pretty=format:"%s" --no-merges 2>/dev/null
git diff --name-only HEAD 2>/dev/null
git diff --name-only --cached 2>/dev/null

Read a sample of recently changed files to understand:

  • Libraries/frameworks in use: Import statements, dependencies
  • Patterns being implemented: Design patterns, architectural approaches
  • Error patterns: Recent error messages in logs or test output
  • Technology choices: Language features, APIs, protocols

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.
