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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00434 | $0.00434 |
| Opus 5 | $0.00217 | $0.00217 |
| Sonnet 5 | $0.00087 | $0.00087 |
| Haiku 4.5 | $0.00043 | $0.00043 |
Grade A, and why
plugins-and-skills CLAUDE.md 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 7d 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.
What it actually says
plugins-and-skills
Canonical source for all Claude Code skills, plugins, and extension-creation tools.
Structure
marketing-copy/skills/ — 10 marketing & copywriting skills
dev-toolkit/skills/ — 14 development & extension-creation skills
app-builder/skills/ — 7 app building & automation skills
create-plugins/ — Extension creation toolkit (agents, commands, scripts, skills, templates)
How It Works
- Personal use: Run
./setup-personal.shto symlink all skills to~/.claude/skills/(works in every project) - Client use:
/plugin marketplace add ~/dev/plugins-and-skillsthen/plugin install marketing-copy - Marketplace: Root
.claude-plugin/marketplace.jsonlists all 3 plugins
Rules
- This is the ONLY canonical location for skills. Do not duplicate skills into project repos.
- Each skill directory must have a
SKILL.mdfile. - Naming: clear, precise, 6th-grader-understandable. No jargon, no version numbers in names.
- Skills auto-activate based on their
description:field — write it well.

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.
