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 | $0.01853 | $0.01853 |
| Opus 5.5 | $0.00741 | $0.00741 |
| Sonnet 5.5 | $0.00371 | $0.00371 |
| Haiku 4.5 | $0.00185 | $0.00185 |
Grade A, and why
skills AGENTS.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 15d 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.
How it starts
The opening of the file, as written. The whole thing — 145 lines — stays where its author put it; the contents beside it link to each section on GitHub.
AGENTS.md
Kelly's App-in-Skill workspace: 78 skills under skills/, most pairing an agent operating
procedure with a Busabase-backed local browser UI for human review and approval. A few are
UI-less helpers (agent-rules, publish-skills, the *-community forum CLIs).
Skill taxonomy
Every skill declares its own classification in SKILL.md frontmatter. That frontmatter is the
single source of truth — the site sections, the site filters, the README tables, and the
marketplace tags are all derived from it. Nothing is maintained in a second list.

tags:

Put this under metadata:, not as top-level category: / tags: keys. gh skill publish
validates frontmatter against the agentskills.io spec and one bad skill blocks the whole release;
metadata is the spec's free-form field (--fix only strips metadata.github-* install
metadata, leaving other subkeys alone). Top-level custom keys have no such guarantee.

One of these thirteen. They are mutually exclusive and decide which section a skill appears in.

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.
