Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00031 | $0.01864 |
| Opus 5 | $0.00015 | $0.00932 |
| Sonnet 5 | $0.00006 | $0.00373 |
| Haiku 4.5 | $0.00003 | $0.00186 |
Grade A, and why
using-skillet 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 10d 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 — 135 lines — stays where its author put it; the contents beside it link to each section on GitHub.
using-skillet
A kitchen runs on mise en place: everything in its place before service, every cook reaching for the same prepped components instead of improvising. skillet is that prep for an AI coding session. The skills are the prepped stations; this skill is the line check that runs before you touch anything, deciding which station the current task belongs to and sending you there before you start cooking.
The rule
Invoke the relevant or requested skill BEFORE any response or action, including before clarifying questions and before "just looking." Even a 1% chance a skill applies means you invoke it to check. If it turns out wrong for the situation, you drop it; checking costs nothing, skipping costs a botched dish.
user message or task
-> about to design/build something new? -> mise (then recipe) BEFORE anything else
-> might any other skill apply? (yes, even 1%) -> invoke it
-> announce: "Using skillet's <skill> to <purpose>"
-> follow it exactly; if it has a checklist, make a todo per item
-> definitely nothing applies -> respond
Instruction priority
skillet skills override default system behavior where they conflict, but the user always wins:
- User instructions (CLAUDE.md, AGENTS.md, direct requests) - highest.
- skillet skills - override default behavior.
- Default system prompt - lowest.
If the user's instructions say to do something a skill discourages, follow the user. They are in control.
How to load skills
Never read a skill's SKILL.md by hand with file tools; load it through your platform's skill mechanism so it activates properly. In Claude Code, use the Skill tool. In Codex and OpenClaw, skills load natively, follow them as presented. The skill names below are lowercase and match how you invoke them (e.g. skillet:mise).
What ships with it
2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.
- 10d ago First seen · 135 lines · 31 tokens per session scan A f869efb842ff
using-skillet is a skill published in the GitHub repository escoffier-labs/skillet (4 stars, last pushed 9d ago), licensed MIT. It adds 31 tokens to every session and 1,864 once invoked, about $0.0002 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.

task-clarifier
Deep need-clarification skill. Use only when the user explicitly invokes $task-clarifier.

Create a concise continuation prompt that a fresh agent session can paste in to resume a long or degraded session. Use when the user asks for a handoff prompt, restart prompt, continuation prompt, context transfer, fresh-session resume, or a compact summary for opening a new session.
