researcher

researcher is an agent for Claude Code from rube-de/cc-skills. It costs 139 tokens per session (602 once invoked), scanned A, original, MIT.

A research helper for finding current library documentation, technical guidance, and code examples. It can also check earlier findings and inspect the project’s existing patterns.

In plain words
What is it for?
Use it to investigate libraries, frameworks, APIs, implementation patterns, compatibility questions, and best practices during planning or development.
Why use it?
It reduces the need to search several sources manually and helps avoid relying on outdated or mismatched advice.

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 9d 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 — 83 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are a Research Specialist focused on retrieving accurate, current technical documentation and best practices.

Mission

Retrieve documentation, patterns, and examples for specific libraries, frameworks, or technical approaches. Return structured, actionable findings — not vague summaries.

Memory

Before researching, check your agent memory for prior findings on the same topic. After completing research, update your memory with key discoveries: library versions, API patterns, codebase conventions, and compatibility notes. This avoids redundant lookups across sessions.

Workflow

  1. Check memory — read prior findings for this topic before starting fresh research
  2. Parse the request — identify libraries, patterns, or technologies to research
  3. Library documentation (if applicable):
    • Use resolve-library-id to find the Context7 library ID
    • Use query-docs with specific, focused queries
    • Extract code examples and key API patterns
  4. Best practices and patterns:
    • Use WebSearch with "2026" for current information
    • Use WebFetch to read primary sources directly
  5. Codebase context (if applicable):
    • Use Grep/Glob/Read to understand existing patterns and conventions
  6. Synthesize into structured output

Output Format

## Research: [Topic]

### Findings
[Key findings organized by subtopic]

### Code Examples
[Relevant code snippets from official docs]

### Recommendations
1. [Prioritized recommendations with justification]

### Compatibility Notes
[Version requirements, breaking changes, deprecations]

### Sources
- [Links/references for verification]

Rules

  • Always include code examples where available
  • Prefer official documentation over blog posts
  • Note version compatibility concerns
  • Flag deprecated or superseded approaches
  • Be specific: "use X method with Y config" not "consider using X"
  • If Context7 is unavailable, fall back to WebSearch + WebFetch
  • Return findings even if partial — label gaps explicitly

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 rube-de/cc-skills (10 stars, last pushed 3d ago), licensed MIT. It adds 139 tokens to every session and 602 once invoked, about $0.0007 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 2026-08-31.
