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 | $0.01083 | $0.01083 |
| Opus 5.5 | $0.00433 | $0.00433 |
| Sonnet 5.5 | $0.00217 | $0.00217 |
| Haiku 4.5 | $0.00108 | $0.00108 |
Grade B, and why
agent-skills AGENTS.md scanned grade B with 1 finding 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 22d 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.
Enumerates other installed skillsmediumAgent snooping
Other skills' SKILL.md files reveal prompts, capabilities and secrets that should be invisible to peers.

The opening of the file, as written. The whole thing — 92 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Repository Guidelines
Project Structure & Module Organization
skills/holds each skill in its own folder (kebab-case). Each skill has aSKILL.mdfile with YAML frontmatter (name,description) and Markdown guidance.- Some skills include reference files alongside the
SKILL.md(e.g.skills/agents-md/references/). - Top-level files:
README.md(overview and install docs).
Install / Development Commands
Primary install (recommended)
npx skills add mblode/agent-skills -g
Installs all skills at user level via the skills CLI (see the deploy chain below). Without -g the CLI installs into the current project instead. Works with Claude Code, Codex, Cursor, and OpenCode.
Install a single skill:
npx skills add mblode/agent-skills -g --skill tidy -y
Local dev: symlink hot-swap
For editing skills in place without reinstalling:
# One-time: symlink the repo's skills folder into the deploy target
ln -s /path/to/agent-skills/skills/<name> ~/.claude/skills/<name>
Changes to the repo files take effect immediately, with no re-install needed. Unlink with unlink ~/.claude/skills/<name> when done.
The deploy chain: skills add writes the content once to ~/.agents/skills/<name>/. Agents that read that canonical path directly, which is every agent whose skillsDir is .agents/skills (Codex, Cursor, and most others), need nothing further; the CLI calls them universal and installs there rather than into ~/.codex/skills or ~/.cursor/skills. Claude Code reads .claude/skills, so it alone gets a relative symlink, ~/.claude/skills/<name> -> ../../.agents/skills/<name>. Editing this repo changes none of them until you reinstall or symlink the folder directly.
Smoke-test
Confirm files landed correctly after install:
ls ~/.claude/skills/tidy/
# Expected: SKILL.md (plus any references/ folder)
For a full install smoke-check:
ls ~/.claude/skills/ | sort
Other repositories may contribute installed skills. Compare each owned folder recursively with its source; a directory listing alone does not establish parity.
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.

agent-skills AGENTS.md is an instructions file published in the GitHub repository mblode/agent-skills (151 stars, last pushed 3d ago), licensed MIT. It adds 1,083 tokens to every session, about $0.0043 per session on Opus 5.5. A static security scan graded it B with 1 finding (enumerates other installed skills). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
