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

deep-research 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 11d 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.

Deep Research

Produce a thorough, cited report from multiple web sources on an open-ended topic. This is the broadest of the research-family skills — research answers one narrow, verifiable technical question against this codebase, and market-research produces a business decision memo; this skill produces a long-form, themed report on any topic, technical or not, sourced from the open web.

When to Activate

  • The user wants to research any topic in depth: "research X", "deep dive into Y", "investigate Z", "what's the current state of W"
  • Competitive, technology, or trend analysis that isn't narrowly scoped to a business decision
  • Any question requiring synthesis across many independent sources

Tooling

Use whatever web search and page-fetch tools are available in the current environment (e.g. WebSearch and WebFetch). If MCP servers such as firecrawl or exa are configured and available, prefer them for broader crawl/search coverage — they are not required.

Workflow

Step 1: Understand the Goal

Ask 1-2 quick clarifying questions: "What's your goal — learning, making a decision, or writing something?" and "Any specific angle or depth you want?" If the user says "just research it," skip ahead with reasonable defaults rather than blocking on clarification.

Step 2: Plan the Research

Break the topic into 3-5 research sub-questions before searching. Example — topic "impact of AI on healthcare": what are the main applications today; what clinical outcomes have been measured; what are the regulatory challenges; who are the leading companies; what's the market trajectory. Decomposing first prevents the search from wandering.

Step 3: Execute Multi-Source Search

For each sub-question, search with 2-3 different keyword variations, mixing general and recency-focused queries. Aim for 15-30 unique sources total across all sub-questions. Prioritize academic, official, and reputable-outlet sources over blogs, and blogs over forums.

Step 4: Deep-Read Key Sources

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.
