researcher is an agent for Claude Code from ariaxhan/kernel-claude. It costs 39 tokens per session (1,626 once invoked), scanned A, original, MIT.

A research agent that investigates existing solutions, software packages, common problems, and recommended practices before implementation begins.

In plain words
What is it for?
Use it to research unfamiliar technologies, compare packages or integrations, find documented pitfalls, and record findings before coding.
Why use it?
It helps avoid choosing unsuitable tools, repeating known mistakes, or building something that already exists.

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 1mo 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 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 ariaxhan/kernel-claude (14 stars, last pushed 2d ago), licensed MIT. It adds 39 tokens to every session and 1,626 once invoked, about $0.0002 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 2026-08-30.
