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 | $0.00457 | $0.00457 |
| Opus 5 | $0.00229 | $0.00229 |
| Sonnet 5 | $0.00091 | $0.00091 |
| Haiku 4.5 | $0.00046 | $0.00046 |
Grade A, and why
claude-marketplace 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 4d 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
This repository is a Claude Code plugin marketplace. The catalog is .claude-plugin/marketplace.json. Each plugin lives in plugins/<name>/ with its own .claude-plugin/plugin.json and optional skills/, commands/, and README.md.
Plugins: nuxt, video-to-article, dev-azdo (Azure DevOps), cc (Claude Code authoring), aiwork (.aiwork/ protocol and the triage, spec, tickets, implement, review skills), browser (playwright-cli-based browser automation: playwright-cli, showme, page-bridge, pick).
Deprecated plugins live in _archived/ and are not listed in marketplace.json. Do not re-add them unless explicitly asked. _archived/dev-flow/ (manifest name df) was split into dev-azdo and aiwork. Only its manifest and README remain.
Rules
- Versioning and releases are handled by the
/releasecommand. Don't bump plugin versions in feature or fix commits. - Always update README.md when adding plugins or making significant changes.
- Never state exact counts of steps or items in docs. They drift as things change.
- Never give a custom command and a skill the same name. It confuses Claude Code.
- When working on plugins or skills here, proactively load the
plugin-creatorandskill-creatorskills.
Useful facts from the docs
- Paths: use
${CLAUDE_SKILL_DIR}for files in the skill's own directory and${CLAUDE_PLUGIN_ROOT}for other plugin files. Never use relative paths, they don't resolve. - Command naming:
commands/foo/bar.mdbecomes/plugin-name:foo:bar. Aname:frontmatter field is ignored in command files. In plugin skills it replaces the last segment of the command, soskills/review/SKILL.mdwithname: fancybecomes/plugin-name:fancy. - Reference docs under https://code.claude.com/docs/en/:
plugins.md,plugins-reference.md,plugin-marketplaces.md,skills.md,slash-commands.md.
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.
