Install

Works with every agent the skills CLI supports.

npx skills add https://github.com/heyvhuang/ship-faster --skill skill-creator
  1. 01

    Install

    Run the command in your project. The CLI asks which agents to install for.

  2. 02

    Describe the task

    Ask your agent for something this skill covers. It loads skill-creator automatically when relevant.

  3. 03

    Review the result

    The agent follows the SKILL.md steps, scripts and references bundled with the skill.

SKILL.md

The instructions your agent reads when the skill is triggered.

Skill Creator

Build skills that behave like “mini senior engineers”: trigger correctly, run deterministically, and leave resumable artifacts on disk.

What good looks like (Ship Faster standard)

  • SKILL.md: short and triggerable (routing + safety + I/O + output contract). Avoid long tutorials here.
  • references/: deep docs loaded only when needed (progressive disclosure). Link directly from SKILL.md.
  • scripts/: deterministic helpers for repetitive/fragile work (prefer this over re-writing code in chat).
  • assets/: templates or files to copy (not meant to be loaded into context).

Deep guidance:

  • Progressive disclosure + authoring principles: references/skill-design-principles.md
  • Workflow structure patterns: workflows.md
  • Output templates/patterns: output-patterns.md

Creation flow (recommended)

  1. Collect trigger examples (real user phrases that should activate the skill).
  2. Define the I/O contract (paths only) + required artifacts:
    • What files does the skill read?
    • What files must it write (plans, evidence, summaries)?
  3. Implement reusable resources first:
    • add scripts/ for deterministic steps
    • add references/ for heavy documentation
    • add assets/ for templates / boilerplate
  4. Write SKILL.md last:
    • frontmatter description should include trigger phrases
    • body should be short and link out to the resources above
  5. Validate + package (optional) using the scripts below.

Scripts

All scripts live in scripts/ in this skill folder.

Initialize a new skill folder

python scripts/init_skill.py <skill-name> --path <output-directory>

Validate a skill (frontmatter + basic conventions)

python scripts/quick_validate.py /path/to/<skill-name>

Sync catalogs/assets (manifest, skills-map, docs catalog)

python scripts/sync_catalog.py

Lint skills (compat + quality gates)

python scripts/skill_lint.py --check-generated

Package a skill into a distributable .skill zip (optional)

python scripts/package_skill.py /path/to/<skill-name> [output-directory]

Notes for Ship Faster contributors

  • Prefer prefix naming: workflow-, tool-, review-, mcp-, skill-, publish-.
  • Keep side effects gated: write a plan first, ask for explicit confirmation, then execute, then verify.
  • If you add/remove a skill, update the catalog: skills/manifest.json.

Claude Code: Slash Commands merged into Skills

Claude Code now treats custom slash commands and skills as the same concept:

  • .claude/commands/<name>.md and .claude/skills/<name>/SKILL.md both create /<name>
  • Existing .claude/commands/ files keep working (no migration required)
  • Prefer creating skills going forward so you can bundle references/, scripts/, and use subagents

Useful frontmatter knobs (Claude Code):

  • disable-model-invocation: true - only user can invoke (good for side-effect workflows)
  • user-invocable: false - hide from users; Claude-only background knowledge
  • context: fork + agent: Explore|Plan|... - run skill in a subagent (good for research)
  • allowed-tools - restrict tool surface when this skill is active

FAQ

What does the skill-creator skill do?

Create or refactor Ship Faster-style skills (SKILL.md + references/ + scripts/). Use when adding a new skill, tightening trigger descriptions, splitting long docs into references, defining artifact-first I/O contracts, or packaging/validating a skill.

How do I install skill-creator?

Run npx skills add https://github.com/heyvhuang/ship-faster --skill skill-creator in your project. The skills CLI detects the agents you use and copies the skill into the right folder. For Claude Code you can also place the skill folder at ~/.claude/skills/skill-creator/ (personal) or .claude/skills/skill-creator/ (project).

Which AI agents can use skill-creator?

Any agent that supports the open Agent Skills format (a folder with a SKILL.md file), including Claude Code, Codex, Cursor, GitHub Copilot, Gemini CLI, Windsurf, Cline, OpenCode and more.

Is skill-creator safe to install?

No partner security audit is available yet. Skills can run commands and scripts, so read the SKILL.md and any bundled files before installing.

codex-pet

prime-skills/runcomfy-agent-skills

Codex Pet generator on RunComfy. Build a Codex-compatible Codex Pet spritesheet.webp + pet.json from a single reference image, drop it into ${CODEXHOME:-$HOME/.codex}/pets/ / and Codex picks it up as a custom Codex Pet next to the 8 built-ins. This skill produces the exact Codex Pet atlas Codex expects (1536x1872 PNG/WebP, 8 cols x 9 rows, 192x208 cells, 9 animation states — idle, running-right, running-left, waving, jumping, failed, waiting, running, review). Calls OpenAI GPT Image 2 edit ONCE via the local RunComfy CLI as runcomfy run openai/gpt-image-2/edit to produce a canonical Codex Pet pose, then assembles all 9 animation rows programmatically with ImageMagick micro-transforms — no Codex Pro, no $imagegen, no OPENAIAPIKEY required, only RUNCOMFYTOKEN. Triggers on "codex pet", "create codex pet", "make codex pet", "hatch codex pet", "/hatch image", "desktop pet codex", "codex pets", "spritesheet.webp", or any explicit ask to build a custom pet for OpenAI Codex.
