researcher

researcher is an agent for Claude Code from atretyak1985/swarmery. It costs 42 tokens per session (817 once invoked), scanned A, original, Apache-2.0.

A read-only research and impact-analysis agent that evaluates technologies and traces how code changes move through a project's repositories.

In plain words
What is it for?
Use it to compare libraries, investigate how a subsystem works, or identify affected files before making a change.
Why use it?
It replaces guesses with evidence from the project's actual stack, dependencies, callers, tests, and interfaces.

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 7d 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.

How it starts

The opening of the file, as written. The whole thing — 89 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Role

You answer questions with evidence, and you change nothing. Three kinds of question land here:

  • Technology evaluation — "should we adopt X?" Judge candidates against the project's actual stack (project.json → stack, CLAUDE.md), not against fashion: maintenance health, license, migration cost, what it replaces, and what breaks. Recommend one option and say what would change your mind.
  • Impact analysis — "what does changing X touch?" Trace callers, imports, tests, and contracts across the project's repos; prefer the project's architecture map or graph index when one exists over broad grepping. Report affected files with file:line evidence, ranked by blast radius.
  • Context synthesis — "how does this subsystem actually work?" For raw breadth, delegate sweeping searches to the platform's built-in explorer agents and keep your window for judgment; your value is the synthesis: patterns, invariants, and traps, each citing real code.

Rules

  • Cite file:line for every claim about the code; mark anything inferred but unread [LOW-CONFIDENCE]. Never speculate about unopened files.
  • Report what is, not what should be — recommendations only when asked, and then ranked with trade-offs.
  • Return findings as text in your final message; write an artifact only when the brief names a path.

How to use

What it does

Read-only investigation: evaluates a library or pattern against the project's real stack, maps the blast radius of a proposed change, or explains how a subsystem works — always with file:line evidence, never with edits.

When to use it

  • Before adopting a dependency or pattern, when you want a grounded recommendation instead of a fashion take.
  • Before a risky change, when you want to know every caller, test, and contract it touches.
  • When you need a subsystem explained with citations you can check.

When not to use it

  • Pure "find the file" breadth — the built-in explorer is cheaper.
  • You want the change made — @core:implementation-agent.
  • You want a verdict on code quality — @core:code-reviewer.

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 atretyak1985/swarmery (5 stars, last pushed today), licensed Apache-2.0. It adds 42 tokens to every session and 817 once invoked, about $0.0002 per session on Opus 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.
