AI Skills
Reusable AI agent skills maintained in this repository. The work is shaped by<br>Sebastian Wessel's article<br>Spec-Driven Development,<br>which explains this repository's spec-first approach for keeping autonomous AI<br>agents aligned from business intent through implementation and review. Each<br>skill lives in its own subdirectory under skills/ and follows Anthropic's<br>Agent Skills best practices.

Skill<br>Description<br>Human docs
spec-architect<br>Use when specs need creation, review, repair, or approval before autonomous or parallel AI implementation without ambiguity, invention, interface mismatch, drift, or gaps.<br>docs
spec-implementation-planner<br>Use when approved specs need end-to-end waves, AFK tickets, parallel-agent plans, dependencies, status tracking, or readiness checks.<br>docs
spec-implementation-review<br>Use when a completed or partial spec implementation wave, plan, or cross-ticket solution needs review before acceptance, merge, release, or handoff.<br>docs
spec-ticket-implementation<br>Use when implementing one approved spec plan ticket with strict read/write scope, acceptance verification, dependency checks, and no implementation-time decisions.<br>docs
Spec-Driven Development
Read<br>Spec-Driven Development<br>for the rationale behind this repository. The article describes how clear specs,<br>implementation plans, ticket execution, and review gates work together so AI<br>agents can build production-ready systems without drifting from the intended<br>business outcome.
Installation
Install this skill package with the open skills ecosystem CLI:
npx skills add sebastianwessel/skills
See Vercel's announcement of<br>skills<br>and skills.sh for the package ecosystem.
Repository Layout
└── SKILL.md">skills/<br>└── /<br>└── SKILL.md
Optional per-skill directories include references/, scripts/, assets/,<br>and agents/.
Human-facing skill documentation lives outside the executable skill package:
.md">docs/<br>└── skills/<br>└── .md
Documentation Pattern
Each skill should have a concise human docs page with the same structure:
What the skill is for.
Installation.
What it does.
How it works.
Workflow or modes.
Included files.
Validation and safety notes.
Adding a Skill
Create skills//SKILL.md.
Use concise YAML frontmatter with name and description.
Keep detailed reference material in files linked directly from SKILL.md.
Add docs/skills/.md for human-facing documentation.

Maintainer Notes
Repository instructions for agents are in AGENTS.md. Claude reads<br>CLAUDE.md, which points back to the same shared guidance.
