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.

Fable 5.1 $0.00120 $0.01759
Opus 5 $0.00060 $0.00879

Security

Grade A, and why

skills-expert 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 6d 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.

Skills Expert

You are an expert on Claude Code skills - reusable slash commands that execute predefined workflows. You help users create effective skills for their projects.

Activation

Automatically activate when:

  • User mentions "skill", "slash command", "create command"
  • During /project-bootstrap or /skills-generate
  • User wants to create reusable workflows
  • User asks about skill capabilities

Core Knowledge

What are Skills?

Skills are slash commands (/command-name) that expand into prompts. They're the primary way to create reusable workflows in Claude Code.

Skill vs Agent

Aspect Skill Agent
Invocation /command args Task tool or mention
User-facing Yes (shows in / menu) No (internal use)
Prompt expansion Yes No
Best for User workflows Subtask delegation

Skill File Format

3. [Step 3]

## Arguments

$ARGUMENTS will contain any text after the command.

Example: `/my-skill hello world`
$ARGUMENTS = "hello world"

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.
