Agent Skills

Curated collection of Claude Code skills for autonomous development workflows.

Skills

ask-first

Ask clarifying questions before executing tasks.

Turns Claude into a thoughtful collaborator that asks the right questions before jumping into work. Uses structured Q&A batches (2-4 questions per round with recommendations) to reach 95% confidence, then executes. Prevents assumptions, surfaces ambiguities, and respects your time by only asking what actually matters.

Trigger: /ask-first, "ask me questions first", "clarify before doing", prefix tasks with "ask:"

cli-spec-to-goal

Convert a Node.js CLI tool spec into a Codex /goal-ready bundle.

Turn a rough CLI tool idea (even a vague one) into the three files Codex /goal needs to drive autonomous implementation: GOAL.md, VERIFY.md, and PROGRESS.md. Bakes in six AI-agent-friendly patterns (--json, stdout/stderr separation, exit codes, structured errors, TTY detection, --dry-run) into every goal. Optionally scaffolds a complete CLI project (bin/, src/, package.json, AGENTS.md, CLAUDE.md).

Supports: JavaScript (default) and TypeScript, commander.js, Vitest, conditional SQLite and cosmiconfig.

Prerequisite: This skill generates goal bundles for the Codex /goal autonomous coding workflow. The generated GOAL.md, VERIFY.md, and PROGRESS.md files are designed to be consumed by an AI agent running Codex /goal commands to implement the CLI tool autonomously.

webg-spec-to-goal

Convert a web game idea into a complete Codex /goal-ready Phaser 3 project.

Turn a rough game idea (like "build a Raiden-type game" or "make a card game") into a runnable Phaser 3 scaffold plus every goal folder needed for autonomous implementation. Auto-detects genre (shoot-em-up, card game, platformer, tower defense, puzzle), decomposes into 5-7 goals following a universal build order, and bakes in state bridge verification (window.GAME_STATE + Playwright).

Supports: shoot-em-up, card-game, platformer, tower-defense, puzzle genres and their variants. Also supports extending existing games with new features.

Prerequisite: This skill generates goal bundles for the Codex /goal autonomous coding workflow. The generated scaffold and goal folders are designed to be consumed by an AI agent running sequential Codex /goal commands to build the game autonomously.

wp-spec-to-goal

Convert a WordPress plugin idea into a Codex /goal-ready bundle.

Turn a rough WordPress plugin or feature idea into the three files Codex /goal needs: GOAL.md, VERIFY.md, and PROGRESS.md with wp-env + Playwright + wp-eval verification baked in. Optionally scaffolds a missing plugin folder, .wp-env.json, package.json, and AGENTS.md.

Supports: New plugins and features for existing plugins, wp-env development environment, Playwright browser testing, wp-eval PHP verification.

Prerequisite: This skill generates goal bundles for the Codex /goal autonomous coding workflow. The generated goal trio is designed to be consumed by an AI agent running Codex /goal commands to implement the WordPress plugin autonomously.
