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-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 8d 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 Researcher

A comprehensive research workflow skill that guides Claude through systematic, multi-layered research on any topic.

When to use this skill

Use this skill when the user:

  • Asks for "deep research" or "comprehensive research" on a topic
  • Needs thorough investigation or due diligence
  • Requests market research or competitive analysis
  • Wants technical deep-dives or architecture reviews
  • Needs literature reviews or trend analysis
  • Asks for detailed reports with multiple perspectives

Research Workflow

Step 1: Define Research Scope and Objectives

Start by clearly establishing research parameters:

  1. Identify the main research question - What is the primary question to investigate?
  2. Define scope boundaries - What aspects should be included or excluded?
  3. Determine depth requirements - How detailed should the research be?
  4. Clarify expected deliverables - What format and structure for output?
  5. List key areas of focus - What specific subtopics to explore?

Document these parameters before proceeding.

Step 2: Conduct Initial Exploratory Research

Begin with broad reconnaissance to map the landscape:

  1. Search for overview information - Find general information, definitions, and context
  2. Identify key sources - Look for authoritative sources, recent publications, expert opinions
  3. Note initial findings - Create preliminary list of important concepts, terms, themes
  4. Discover related topics - Identify adjacent areas that may be relevant
  5. Assess information gaps - Note what's available vs. what needs deeper investigation

Create an initial research map with main themes and subtopics.

Step 3: Deep Dive into Key Areas

For each identified key area, conduct detailed investigation:

  1. Targeted searches - Use specific queries for each subtopic
  2. Multiple perspectives - Seek diverse viewpoints and approaches
  3. Technical details - Gather specific data, statistics, methodologies
  4. Historical context - Understand evolution and background
  5. Current state - Identify latest developments and trends
  6. Future outlook - Look for predictions, projections, emerging patterns

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.
