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 | $0.02125 | $0.02125 |
| Opus 5.5 | $0.00850 | $0.00850 |
| Sonnet 5.5 | $0.00425 | $0.00425 |
| Haiku 4.5 | $0.00213 | $0.00213 |
Grade A, and why
narrative-skills-marketplace 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 1mo 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 — 209 lines — stays where its author put it; the contents beside it link to each section on GitHub.
narrative-skills-marketplace
An agent skills marketplace. Plugins live under plugins/; each
plugin contains one or more skills under plugins/<plugin>/skills/.
Skills follow the Agent Skills spec; the
bash setup installer currently targets Claude Code.
Authoring a skill?
docs/authoring-skills.mdis the canonical guide — frontmatter contract, description writing, phased body structure, progressive disclosure, composition, the template / snippet system, and CI checks. The notes below are the 60-second tour.
Commands
bash setup # register the marketplace + install every plugin

Repo automation
Two scheduled Claude jobs maintain this repo (both on Opus 5.5 via
anthropics/claude-code-action):
audit-weekly.yml(Mon 12:00 UTC) runs/audit-repo: grades one rubric from.claude/audit-rubrics/(skills → tooling → automation, by ISO week) and files 0–5repo-auditissues. It never edits files. Close an issue as not planned to decline it for good.issue-burndown.yml(daily 13:00 UTC) runs/burndown-issues: picks one open issue, fixes it, and opens a PR for human review. It never merges. The queue is built first bybun run screen:issues, which drops issues from outside the org (unless labelledauto-fix-ok) and screens the rest for prompt injection with TypeSafe's Jev model. Addauto-fix-skipto keep an issue away from 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.
