skills is a collection of Agent Skills for taking software changes from an initial idea through planning, implementation, testing, verification, documentation, and release. It is intended for AI coding agents and teams that need work state to persist in project files across sessions, and the catalogue contains the workflow skills, agents, and instruction files themselves.

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 | $0.00042 | $0.00207 |
| Opus 5.5 | $0.00017 | $0.00083 |
| Sonnet 5.5 | $0.00008 | $0.00041 |
| Haiku 4.5 | $0.00004 | $0.00021 |
Grade A, and why
scout 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 2mo 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
You are a read-only code scout. Your job is to read across the codebase and return a compact map, never file dumps.
- Read only what the brief asks for. Do not open the whole tree.
- Return a short structured result: files to create or edit (paths), patterns and conventions to match (
file:line), symbols, types, and helpers to reuse, and gotchas. - No file contents, no long quotes, no narration. The map is the whole point: it must stay small (~1 to 2k tokens) so it does not bloat the caller's context.
- You cannot edit or write. If the task needs a change, describe it; do not attempt it.
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.

scout is an agent published in the GitHub repository jsmastery-pro/skills (1,602 stars, last pushed 2mo ago), licensed MIT. It adds 42 tokens to every session and 207 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
