skill-creator: Instructions file for Codex

AGENTS.md

skill-creator AGENTS.md is an instructions file for Codex, OpenCode from sandiiarov/skill-creator. It costs 412 tokens per session, scanned A, original, MIT.

A repository guide containing the project overview, directory layout, commands, runtime requirements, and coding conventions for a TypeScript command-line tool. A command-line tool is a program operated from a terminal.

In plain words
What is it for?
Use it when working on the skill-creator package, especially its CLI, runtime utilities, OpenAPI support, GraphQL support, tests, and build process.
Why use it?
It gives coding agents the project-specific context needed to install, build, test, type-check, lint, and edit the right files. It also helps prevent changes that conflict with the repository's structure or style.

Written for Codex and OpenCode: the file is AGENTS.md. Also seen: mentions AGENTS.md.

This is sandiiarov/skill-creator's own configuration. It tells Codex and OpenCode how to work on skill-creator itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything skill-creator configures →

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-creator 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.

Guidance for coding agents working in this repository.

Project overview

  • Package: @asnd/skill-creator (CLI binary: skill-creator)
  • Purpose: TypeScript CLI that turns MCP servers, OpenAPI specs, and GraphQL endpoints into runtime CLIs without code generation.
  • Runtime: Node.js >= 26, ESM modules.
  • Package manager: pnpm.

Useful commands

  • Install dependencies: pnpm install
  • Run CLI in development: pnpm dev -- <args>
  • Build: pnpm build
  • Test: pnpm test
  • Typecheck: pnpm typecheck
  • Lint: pnpm lint
  • Format check: pnpm fmt:check
  • Format: pnpm fmt

Repository layout

  • src/cli/ - CLI entrypoint and argument parsing.
  • src/core/ - shared runtime utilities, types, output, filtering, caching, and secret handling.
  • src/openapi/ - OpenAPI loading, reference resolution, parameter handling, extraction, and execution.
  • src/**/*.test.ts - Vitest tests colocated next to the source they cover.
  • src/test-fixtures/ - shared test fixtures.
  • dist/ - build output; do not edit manually.

Coding guidelines

  • Prefer small, focused TypeScript modules with explicit types.
  • Keep code ESM-compatible and avoid CommonJS patterns.
  • Validate external inputs with existing Zod/type utilities where practical.
  • Add or update Vitest coverage for behavior changes.
  • Do not hand-edit generated build artifacts in dist/.
  • Use existing formatter/linter settings (oxfmt, oxlint) rather than introducing new style conventions.

Before finishing changes

Run the relevant checks for the change size:

  1. pnpm typecheck
  2. pnpm test

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.
