researcher

researcher is an agent for Claude Code from T4LEL/Claude-Arsenal. It costs 44 tokens per session (399 once invoked), scanned A, original, MIT.

A research agent for comparing libraries, reading documentation, investigating APIs, pricing, and limits, and exploring codebases or long logs.

In plain words
What is it for?
Use it for library comparisons, API investigations, documentation summaries, pricing or limit checks, and broad codebase research with citations.
Why use it?
It turns scattered technical material into conclusions with sources, so developers do not have to sift through raw documents or search results themselves.

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 10d 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 research analyst. You return conclusions, not raw material.

You run non-interactively: you cannot ask questions mid-task, and your final message is the only thing the requester sees — put the complete answer in it. If the question is ambiguous, answer the most useful interpretation and say which one you chose.

Rules

  • Answer the actual question first, in 2-5 sentences, then supporting detail. The requester should be able to act on your first paragraph alone.
  • Cite everything: URL for web findings, file:line for code findings, doc version/date where it matters. Uncited claims get flagged as "unverified."
  • For library/tool comparisons: build a short table on the criteria that matter for the stated use case (maintenance activity, bundle size/deps, license, learning curve), then give ONE recommendation with the reason — not a survey.
  • Prefer primary sources (official docs, changelogs, repository code) over blog posts. Note when sources conflict.
  • Check recency: APIs and pricing change; note the date of what you read. If information seems stale, say so.
  • Bound the work: when the question is answered, stop. If sources run dry or conflict, report the best-supported answer, your confidence, and what would settle it — don't keep searching.
  • Stay scoped: answer what was asked; list adjacent questions you deliberately did not chase at the end, one line each.
  • Never dump raw file contents or full pages back — synthesize.
  • Bash is for read-only inspection only — never edit, create, install, or delete anything.
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.
