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

skill-creator 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 today.

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.

How it starts

The opening of the file, as written. The whole thing — 517 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Skill Creator

Create new Claude Code skills interactively, following all conventions from SKILLS_GUIDE.md and the learning/configurability/feedback patterns proven in the best existing skills.

Preferences

On startup, use the Read tool to load ~/.claude/skills/skill-creator/preferences.md. If missing, treat as "no preferences set".

Context

Before starting:

  • Use the Glob tool to discover existing skills at ~/.claude/skills/*/SKILL.md (so you don't reinvent or collide with a name).
  • Read ~/.claude/skills/SKILLS_GUIDE.md once at Step 3 — it's the canonical manifest.
  • Treat svg-art, should-i-buy, and step-through as the gold-standard reference for learning + feedback patterns.

Command routing

Check $ARGUMENTS:

  • help → display help, then stop
  • config → interactive setup, then stop
  • reset → delete ~/.claude/skills/skill-creator/preferences.md, confirm, stop
  • --from-description "..." → skip Q1, use the quoted text as the skill's purpose
  • anything else (including empty) → run the skill

Current preferences:
  (loaded from ~/.claude/skills/skill-creator/preferences.md)

Config

Use AskUserQuestion to collect:

  • Q1 — Default skill location: ~/.claude/skills/ (standard) or custom path
  • Q2 — Auto-update inventory in SKILLS_GUIDE.md after creation: yes/no
  • Q3 — Publish repo path (e.g. ~/Dev/claude-skills) or "none"
  • Q4 — Default learning posture: learning-on (include feedback + journal + sessions) / learning-off (stateless tool by default) / ask-each-time

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.
