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 | $0.03535 | $0.03535 |
| Opus 5 | $0.01767 | $0.01767 |
| Sonnet 5 | $0.00707 | $0.00707 |
| Haiku 4.5 | $0.00353 | $0.00353 |
Grade A, and why
agentic-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 9d 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.
CLAUDE.md
This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
What this repo is
A personal library of Claude / Cursor-compatible agent skills. Each skill is a self-contained folder of Markdown (a SKILL.md plus optional supporting docs) — there is no build system, no test runner, and no application code. "Working on the code" here means authoring and refining skill definitions and their specs.
Public, and forkable. Treat everything here as published: it ships to the plugin marketplace and is documented at https://agentic-skills.vidhunnan.design.
Layout & conventions
- One folder per skill under
skills/, kebab-case, where the folder name must match thenamefield in that skill'sSKILL.mdfrontmatter. - Each skill's entry point is
skills/<name>/SKILL.md. Its frontmatter (name,description,allowed-tools,disable-model-invocation, plus optionallyargument-hint) is the contract that drives how and when the skill triggers — thedescriptiondoubles as the auto-trigger matcher, so it must enumerate the natural-language phrases and the/<name>slash form that should fire it. - Skill folder = plugin. Each
skills/<name>/doubles as an installable plugin by carrying its own.claude-plugin/plugin.jsonnext toSKILL.md. This is the reusable pattern for every future skill: it keeps the "one folder per skill underskills/" convention and the standalone-copy install (cp -r skills/<name> ~/.claude/skills/) working, with no separateplugins/tree. - PRDs for non-trivial skills live in
docs/prds/<name>.md. When aSKILL.mdis still a stub, the PRD is the source of truth for the output template, trigger rules, and per-surface behavior — read it before implementing. Keep the PRD in sync when the skill's scope changes. - The repo-root
.claude-plugin/marketplace.jsonlists every skill as a plugin, eachsourcepointing at itsskills/<name>folder. Add an entry here whenever you add a skill. - Nothing referencing internal/employer-specific systems or unreleased work belongs in this repo (it's headed for public release).
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.

agentic-skills CLAUDE.md is an instructions file published in the GitHub repository vidhunnan/agentic-skills (2 stars, last pushed 3d ago), licensed MIT. It adds 3,535 tokens to every session, about $0.0177 per session on Opus 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.
