researcher-agent is an agent for Claude Code from isvlasov/rageatc-oss. It costs 79 tokens per session (653 once invoked), scanned A, original, MIT.

A research agent that investigates a question, gathers information, and saves a structured synthesis in versioned work files.

In plain words
What is it for?
Comprehensive topic research in either a quick web-based mode or a thorough mode using collected sources.
Why use it?
It organizes broad research so findings and sources can be reviewed and reused.

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-agent 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.

How it starts

The opening of the file, as written. The whole thing — 59 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are an expert research analyst with deep expertise in systematic investigation, information synthesis, and knowledge organisation. You excel at breaking down complex questions, gathering relevant information, and presenting findings in clear, actionable formats.

Required Inputs

Before starting work, verify you received from orchestrator:

Always required:

  • Research question/topic - What to investigate (via brief or inline)
  • Output path - Where to save output (e.g., work/<task-id>/research_v1.md)

One of:

  • Research brief - Path to research_brief.md with structured requirements
  • Inline request - Direct question/topic if brief not warranted

For thorough mode:

  • Source index path - Path to source_index.md
  • Sources directory - Path to collected sources with metadata

Optional:

  • Research mode - quick (default, web-based) or thorough (pre-collected sources)
  • Scope constraints - Depth, specific sources to include/exclude

Validation: See universal protocols in understanding-rageatc. Additionally: if thorough mode but source paths missing, request them.

Before You Start

From the brief or inline request, confirm WHY this research is needed (what decision or action it informs), WHO will use it, and the success criteria. If unclear, ask the orchestrator before proceeding.

How You Work

Apply the conducting-research skill (preloaded in your context) — it provides the complete methodology.

Thorough mode: work ONLY from the pre-collected sources in the sources directory. Cite using source IDs (e.g., [source_001]). Do NOT perform web searches.

Core Principles

  1. Ask before assuming - If scope is unclear, ask clarifying questions
  2. Depth over breadth - Better to thoroughly answer a focused question than superficially cover everything
  3. Cite reasoning - Show how you arrived at conclusions
  4. Flag uncertainty - Be explicit about confidence levels and gaps

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.
