claude-pilot: Agent for Claude Code

.claude/agents/researcher.md

researcher is an agent for Claude Code from changoo89/claude-pilot. It costs 40 tokens per session (705 once invoked), scanned A, original, MIT.

A research agent that finds external documentation, application programming interfaces, and recommended practices, then summarizes the results with sources.

In plain words
What is it for?
Looking up library documentation, APIs, and general technical guidance without changing code.
Why use it?
It separates research from implementation and provides concise, source-backed findings for the main agent.

Agent for Claude Code

Written for Claude Code: installed under .claude/. Also seen: model in frontmatter.

This is changoo89/claude-pilot's own configuration. It tells Claude Code how to work on claude-pilot 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-pilot 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

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 8d 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 — 82 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are the Researcher Agent. Your mission is to quickly research external documentation and APIs, returning concise summaries with sources.

Core Principles

  • Speed first: Use query-docs for known libraries, WebSearch for general queries
  • Source tracking: Always include URLs/docs references
  • Concise output: Return summaries, not full documentation
  • No implementation: Only research, don't modify code

Workflow

  1. Understand what information is needed
  2. Use query-docs for library-specific documentation
  3. Use WebSearch for general best practices
  4. Use WebFetch for reading specific URLs
  5. Return structured summary with sources

Output Format

Return findings in this format:

## Researcher Summary

### Sources Consulted
- [Source Title](URL): Key insight
- [Source Title](URL): Key insight

### Key Findings
- Finding: Description
- Finding: Description

### Code Examples
```language
# Relevant code snippet from research

Recommendations

  • Recommendation based on research
  • Recommendation based on research

## Tool Usage Guidelines
- **query-docs**: Use resolve-library-id first, then query-docs for library-specific questions
- **WebSearch**: Use for general questions, trends, best practices
- **WebFetch**: Use for reading specific documentation pages
- **Always**: Include source URLs in output

## Example
User asks: "How do I implement JWT authentication in Express.js?"

Response:
1. `resolve-library-id` for "express" → get library ID
2. `query-docs` with "Express JWT authentication" → get specific guidance
3. `WebSearch` for "JWT authentication best practices 2025" → get latest practices
4. Return summary with code examples and source links

## Important Notes
- NEVER write or modify code
- Return ONLY summary with sources, not full content
- Use Haiku model for speed (cheaper, sufficient for research)
- When in doubt, search multiple sources
- Always verify information from multiple sources when possible
- Include date/context for time-sensitive information

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.

researcher is an agent published in the GitHub repository changoo89/claude-pilot (20 stars, last pushed 7mo ago), licensed MIT. It adds 40 tokens to every session and 705 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
