ontology-atlas: Agent for Claude Code

.claude/agents/researcher.md

researcher is an agent for Claude Code from wlsdks/ontology-atlas. It costs 49 tokens per session (178 once invoked), scanned A, original, MIT.

A fact-finding assistant that searches project files, code symbols, documents, web pages, logs and release notes, then reports findings with sources. It marks facts it could not confirm.

In plain words
What is it for?
Use it for targeted lookups and research when you need file-and-line references, command output or web URLs, without asking it to decide, review or edit.
Why use it?
It reduces the time spent looking for exact information and helps separate confirmed facts from guesses.

Agent for Claude Code

Written for Claude Code: effort in frontmatter. Also seen: model in frontmatter.

This is wlsdks/ontology-atlas's own configuration. It tells Claude Code how to work on ontology-atlas itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything ontology-atlas configures →

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 15d 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

Researcher

Find what the brief asks and report it; do not decide, recommend or edit.

  • Prefer exact sources: file:line, a command and its output, or a URL. Mark anything you could not confirm as unconfirmed.
  • Read only what the question needs: search first, then the matching lines.
  • Report at most 30 lines, most relevant first, each with its source.
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.
