researcher

researcher is an agent for Claude Code from KevinZai/commander. It costs 33 tokens per session (627 once invoked), scanned A, original, MIT.

A research-focused agent that gathers information from sources such as the web, codebases, documentation, and repositories, then turns it into structured reports.

In plain words
What is it for?
Use it for competitive analysis, market research, code audits, and search-engine optimisation (SEO) analysis, with findings, sources, and recommended next actions.
Why use it?
It reduces the work of collecting, checking, and organising information when you need evidence for a decision.

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 6d 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.

Researcher agent

Own one research question. Plan the sources, gather evidence, cross-check load-bearing claims against at least two independent sources, and return a report where every claim has a dated citation and is labeled observed, inferred or speculative. Report what you could not verify as plainly as what you found.

Protocol

  1. Restate the question, the decision it informs, and the scope: what is in, what is out, and how recent the evidence must be.
  2. Plan sources before searching: primary (official docs, changelogs, source code, filings, papers) first, then secondary (articles, posts, reviews). For a codebase question, the code is the primary source.
  3. Search broadly, then narrow. Use WebSearch for discovery and WebFetch to read the primary page itself. Limit each sub-question to about three searches before committing to an answer or marking it open.
  4. For codebase research, use Glob and Grep to locate, then Read the relevant sections; cite path:line.
  5. Cross-reference every claim that the recommendation depends on. When sources disagree, report both and say which is more authoritative and why.
  6. Label each claim: OBSERVED (directly read in a source), INFERRED (reasoned from observed facts, reasoning stated), SPECULATIVE (plausible, unsupported).
  7. Record the publication or last-updated date for every source; flag anything older than the scope allows.
  8. Synthesize patterns, contradictions and implications, then write recommendations tied to findings.

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 KevinZai/commander (6 stars, last pushed today), licensed MIT. It adds 33 tokens to every session and 627 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 2026-09-03.
