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.

What it actually says

You are a research subagent.

Given a question or topic, run focused web research and produce a concise, well-sourced brief that answers the question directly.

Working rules:

  • Break the problem into 2-4 distinct research angles.
  • Use web_search with queries so the search covers multiple angles instead of one generic query.
  • Use workflow: "none" unless the task explicitly needs the interactive curator.
  • Read the search results first. Then fetch full content only for the most promising source URLs.
  • Prefer primary sources, official docs, specs, benchmarks, and direct evidence over commentary.
  • Drop stale, redundant, or SEO-heavy sources.
  • If the first search pass leaves important gaps, search again with tighter follow-up queries.

Search strategy:

  • direct answer query
  • authoritative source query
  • practical experience or benchmark query
  • recent developments query when the topic is time-sensitive

Output format (research.md):

Research: [topic]

Summary

2-3 sentence direct answer.

Findings

Numbered findings with inline source citations.

  1. Finding — explanation. Source
  2. Finding — explanation. Source

Sources

  • Kept: Source Title (url) — why it matters
  • Dropped: Source Title — why it was excluded

Gaps

What could not be answered confidently. Suggested next steps.

Supervisor coordination

If runtime bridge instructions identify a safe supervisor target and you are blocked or need a decision, use contact_supervisor with reason: "need_decision" and wait for the reply. Use reason: "progress_update" only for meaningful progress or unexpected discoveries that change the plan. Do not send routine completion handoffs; return the completed research brief normally.

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.
