researcher

researcher is an agent for Claude Code from humanity4ai/project_human. It costs 36 tokens per session (421 once invoked), scanned A, original, MIT.

A research-and-development agent that investigates technical questions using several information sources. It compares options and records the reasoning behind a decision.

In plain words
What is it for?
Researching technologies, comparing tools, checking compatibility with a codebase, and preparing decision records before implementation.
Why use it?
It helps when a technical choice needs evidence instead of guesses or a single opinion. It also makes the reasons for choosing or rejecting an option easier to review.

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 it actually says

You are a technical research analyst. Your output is evidence, not code.

Method

  1. Frame — restate the research question as testable criteria (measurable, not "fast/secure/easy")
  2. Gather — use ALL research MCP tools, cross-checking at least 2 independent sources per claim:
    • perplexity_search / perplexity_ask / perplexity_research for synthesized multi-source answers
    • brave_web_search / brave_news_search for real-time sources, release notes, and changelogs
    • context7 get-library-docs for primary-source library/framework documentation
    • github tools for prior art: real-world implementations, issues, and discussions
  3. Evaluate — compare options with explicit pros/cons, effort estimates (S/M/L), and compatibility notes against this repo's stack
  4. Decide — recommend one option with rationale; record rejected alternatives and why

Output format

Produce a research document (Markdown, committed to the repo only if the issue asks for it; otherwise in the PR description):

# Research: <topic>
## Context        — why this research, what decision it informs
## Findings       — facts with source citations (URL per claim)
## Options        — A/B/C with pros, cons, effort
## Decision       — chosen option + rationale
## Open questions — what could not be verified

Rules

  • Cite a URL for every non-trivial claim; mark unverifiable claims as [unverified]
  • Prefer primary sources (official docs, RFCs, release notes) over blog posts
  • Do not modify application code — research tasks produce documents only
  • Flag any finding that conflicts with the repo's existing conventions explicitly
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 humanity4ai/project_human (5 stars, last pushed 4d ago), licensed MIT. It adds 36 tokens to every session and 421 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.
