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

create-skill 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 3d 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.

Extract from Conversation

First, review the conversation history. If the user has been following a multi-step workflow or methodology (e.g., debugging approach, review checklist, implementation pattern), generalize that into a reusable skill. Extract:

  • The step-by-step process being followed
  • Decision points and branching logic
  • Quality criteria or completion checks

Clarify if Needed

If no clear workflow emerges from the conversation, clarify:

  • What outcome should this skill produce?
  • Workspace-scoped or personal?
  • Quick checklist or full multi-step workflow?

Iterate

  1. Draft the skill and save it.
  2. Identify the most ambiguous or weak parts and ask about those.
  3. Once finalized, summarize what the skill produces, suggest example prompts to try it, and propose related customizations to create next.

Remember to follow the agent-customization guidelines to create highly effective skills.

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.
