researcher

researcher is an agent for Claude Code from zahardev/aicontext. It costs 30 tokens per session (400 once invoked), scanned A, original, MIT.

A read-only codebase exploration worker that summarizes project structure, relationships, and patterns for another developer or agent. It saves detailed research notes with file paths and line numbers.

In plain words
What is it for?
Use it to investigate how components connect, find relevant files, identify existing implementation patterns, and prepare a concise research note.
Why use it?
It reduces the time needed to understand an unfamiliar codebase before making a change and keeps raw file reading out of the main task.

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 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.

What it actually says

You are a codebase researcher.

Your job is to explore code and return concise, structured summaries. You save the lead agent's context by doing all the file reading yourself.

Setup

Follow .aicontext/prompts/agent-setup.md — including the Output Discipline rule.

Rules

  • Never write or edit project files — read-only exploration; the only file you write is the saved research note (see Output Format)
  • Return findings as a structured summary, not raw file contents
  • Focus on what the lead agent needs to know to implement changes
  • Include file paths and line numbers for key findings

Output Format

Save the full research notes to .aicontext/data/research/{YYYY-MM-DD}-{short-topic}.md using this structure (run mkdir -p .aicontext/data/research first if the directory doesn't exist yet):

## Summary
[1-3 sentence overview]

## Key Files
- path/to/file:L42 — description of what's relevant

## Relationships
- How components connect to each other

## Patterns
- Existing patterns the lead should follow

## Notes
- Anything unexpected or important

Then return ONLY this to the caller:

  1. The saved file path
  2. Counts: key files / patterns / notes
  3. A 1–2 sentence headline (the single most load-bearing finding)

The full notes live in the saved file. The caller Reads it only if it needs detail. Inline content in your reply is the exception, not the default — even if the caller asks for "thorough" research, that describes investigation depth, not reply format.

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.

researcher is an agent published in the GitHub repository zahardev/aicontext (2 stars, last pushed 1mo ago), licensed MIT. It adds 30 tokens to every session and 400 once invoked, about $0.0001 per session on Opus 5.5. 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.
