skill-recipes

skill-recipes is a skill for Claude Code, Codex from JNZader/repoforge. It costs 53 tokens per session (461 once invoked), scanned A, original, MIT.

A recipe format for skills that need setup instructions. An optional INSTALL.md lists prerequisites, installation and removal commands, checks, and safety rules.

In plain words
What is it for?
Use it when creating or installing skills that require packages, MCP servers, or configuration.
Why use it?
It gives an agent a repeatable way to set up a skill while limiting unsafe changes and stopping when a step fails.

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

skill-recipes 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.

What it actually says

Purpose

Define a pattern where skills are self-installing: an INSTALL.md contains executable setup instructions that an agent follows to configure dependencies, MCP servers, or config.


Recipe Format

own/skills/my-skill/
  SKILL.md         <- the skill itself
  INSTALL.md       <- optional setup recipe

INSTALL.md Structure

# Install: {skill-name}

## Prerequisites
- [ ] Node.js >= 20

## Steps
### 1. Install dependencies
\`\`\`bash
pnpm add -D playwright
\`\`\`

### 2. Verify
\`\`\`bash
npx playwright --version
\`\`\`

## Uninstall
\`\`\`bash
pnpm remove playwright
\`\`\`

Agent Execution Protocol

  1. Read INSTALL.md completely before executing
  2. Check Prerequisites — verify each is met, stop if not
  3. Execute Steps sequentially (Bash for commands, Write for files)
  4. Run Verify step to confirm success
  5. Report results

Safety Rules

  1. NEVER modify files outside project directory without confirmation
  2. NEVER install global packages without confirmation
  3. If a step fails, STOP — do not continue
  4. Show commands to user BEFORE executing

Critical Rules

  1. INSTALL.md is OPTIONAL — skills work without it
  2. Recipes MUST be idempotent — running twice must not break anything
  3. Every recipe MUST have a Verify step
  4. Recipes MUST NOT contain secrets or API keys
  5. Agents MUST show what will execute before running
Changes

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.
