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 | $0.01010 | $0.01010 |
| Opus 5.5 | $0.00404 | $0.00404 |
| Sonnet 5.5 | $0.00202 | $0.00202 |
| Haiku 4.5 | $0.00101 | $0.00101 |
Grade A, and why
skillet 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 — 110 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.
Project Overview
Skillet is a CLI tool written in Go that executes Claude Agent Skills (from agentskills.io) and commands as shell scripts with formatted output. It parses SKILL.md and command.md files, extracts frontmatter configuration (allowed-tools, model, etc.), interpolates variables like {baseDir}, and invokes the Claude CLI with appropriate permissions in headless mode. Output is formatted using Charm libraries (glamour, lipgloss) for clean terminal rendering.
Always test, format and lint code before finishing
go test ./...
go fmt ./...
golangci-lint run
Architecture
Core Components
main.go (cmd/skillet/main.go): Entry point that orchestrates the execution flow:
- Parses CLI flags using custom flag separation logic to support flags anywhere in args
- Resolves skill/command name → file path via
resolverpackage - Builds executor config from merged CLI flags + frontmatter
- Runs executor and formatter concurrently using pipes
- Handles signals and context cancellation
parser (internal/parser/): Parses SKILL.md files with YAML frontmatter
- Extracts frontmatter (name, description, allowed-tools, model, etc.)
- Interpolates
{baseDir}variables in content - Validates skill structure and constraints (name format, field lengths)
command (internal/command/): Parses command .md files (similar to skills but simpler)
- Derives command name from filename
- Supports optional frontmatter (description can be auto-extracted from content)
- Handles variable interpolation like skills
executor (internal/executor/): Builds and runs claude CLI commands
- Constructs args from resolved config (model, allowed-tools, system-prompt, etc.)
- Executes in headless mode with
-p --verbose --output-format stream-json - Provides dry-run mode to show command without executing
formatter (internal/formatter/): Processes claude's stream-json output into readable markdown
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.

skillet AGENTS.md is an instructions file published in the GitHub repository martinemde/skillet (20 stars, last pushed 3mo ago), licensed MIT. It adds 1,010 tokens to every session, about $0.0040 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 2026-08-30.
