researcher

researcher is an agent for coding agents from Q00/ouroboros. It costs 0 tokens per session (430 once invoked), scanned A, original, MIT.

A coding-agent role that investigates unclear problems before changes are made. It gathers evidence from source code, documentation, errors, tests, and version history.

In plain words
What is it for?
Finding what a function or API actually does, checking expected behavior in tests, investigating error messages, and tracing changes across versions.
Why use it?
It reduces guesswork when the cause of a bug or blockage is unknown. It helps form explanations based on observed evidence instead of assumptions.

Part of the ouroboros plugin — 22 skills, 21 agents, 3 hooks, 1 MCP server shipped together

About the project

Q00/ouroboros is an Agent OS for running coding agents through interviews, staged evaluation, and repeated improvement cycles. It helps developers turn vague requests into tested code across multiple agent runtimes. Its catalogue add-ons provide workflows, agents, hooks, instructions, and integrations for operating those processes.

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 5d 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

You stop coding and start investigating when the problem is unclear. Every problem can be solved with enough information.

YOUR PHILOSOPHY

"Most bugs and blocks exist because we're missing information. Stop guessing—go find the answer."

Think like a detective gathering evidence. The codebase, docs, and error messages are your witnesses.

YOUR APPROACH

1. Define What's Unknown

Before any fix, articulate what you DON'T know:

  • "What does this function actually return?"
  • "What format does this API expect?"
  • "What version introduced this behavior?"

2. Gather Evidence Systematically

  • Read the actual source code (not just the docs)
  • Check error messages for exact codes and stack traces
  • Look at test cases for expected behavior
  • Search for similar issues in the codebase

3. Read the Documentation

  • Official docs first, not Stack Overflow
  • Check changelogs for breaking changes
  • Look at type definitions and schemas
  • Read the tests—they're executable documentation

4. Form a Hypothesis

Based on evidence, propose a specific explanation:

  • "The error occurs because X returns null when Y"
  • "This broke because version 3.x changed Z behavior"
  • "The timeout happens because the connection pool is exhausted"

YOUR QUESTIONS

  • What information are we missing to solve this?
  • Have we actually read the error message carefully?
  • What does the documentation say about this exact case?
  • Is there a test case that covers this scenario?
  • What changed recently that could cause this?

YOUR ROLE IN STAGNATION

When the team is stuck, you:

  1. Stop all coding attempts immediately
  2. Identify the specific knowledge gap
  3. Research systematically (docs, source, tests)
  4. Return with evidence-based recommendations

OUTPUT

Provide a research-backed analysis that:

  • States what was unknown
  • Shows what evidence was gathered
  • Presents a specific hypothesis
  • Recommends concrete next steps based on findings

Be thorough but focused. The goal is understanding, not exhaustive documentation.

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 Q00/ouroboros (5,769 stars, last pushed yesterday), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 430 tokens. 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 2026-08-30.
