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 | $0.01595 | $0.01595 |
| Opus 5.5 | $0.00638 | $0.00638 |
| Sonnet 5.5 | $0.00319 | $0.00319 |
| Haiku 4.5 | $0.00160 | $0.00160 |
Grade A, and why
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 today.
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 — 105 lines — stays where its author put it; the contents beside it link to each section on GitHub.
CLAUDE.md
This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
What this repo is
A collection of Claude Code skills (branded ANK Skills). Plugin name: ank.
Most of them form one pipeline — /third-degree (interview) → /spec (SPEC.md) → /tasks (TASKS.md + GitHub issues) → /visualise-plan (pre-code HTML plan) → /review-board (post-feature HTML walkthrough) — with /handoff for dumping context when a window fills up. /review-board is the reference implementation and the most opinionated about output.
/no-yap sits outside that pipeline. It's a response-style skill: it makes Claude answer in ASD-STE100 Simplified Technical English (numbered clauses, one idea per sentence) instead of prose. It produces no file and is not tied to a codebase — it's for any expert domain, not just software.
There was an original build_plan.md that scaffolded the repo; it has been removed. This file is now the source of truth for layout, constraints, and decisions.
Install paths (both supported)
- Claude Code plugin —
.claude-plugin/marketplace.jsonis the catalog (marketplace name:ank-skills);.claude-plugin/plugin.jsondescribes the plugin itself (plugin name:ank) and explicitly lists each skill's path. Install:/plugin marketplace add ananthanandanan/skillsthen/plugin install ank@ank-skills. Skills end up namespaced as/ank:<skill>. - Vercel Labs installer —
npx skills@latest add ananthanandanan/skillsreads theskills/<category>/<name>/SKILL.mdlayout directly and ignores both JSON files.
When adding a new skill, update .claude-plugin/plugin.json's skills array so the plugin install path picks it up. Skills must be listed explicitly because they're nested under skills/<category>/<name>/ rather than directly under skills/<name>/, and Claude Code's auto-discovery only walks one level.

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.

skills CLAUDE.md is an instructions file published in the GitHub repository ananthanandanan/skills (4 stars, last pushed today), licensed MIT. It adds 1,595 tokens to every session, about $0.0064 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 2026-08-31.
