Skills Marketplace: Public

A curated marketplace of reusable skills for Claude Code, Codex, and other assistants that follow the Agent Skills format.

This repo has two jobs:

• provide installable skills you can use immediately
• explain the design ideas behind the more opinionated skills so other builders can adapt them

Who This Is For

This repo is for:

• operators who want practical skills they can install into Claude Code or Codex
• builders who want a reference implementation for agent-team design
• teams that want portable skills rather than assistant-specific one-offs

Quick Start

Install Through Claude Code

Add the marketplace once:

/plugin marketplace add <marketplace-owner>/skills-public

Then open the plugin browser:

/plugin

Install a skill for user scope, then reload Claude Code if needed.

Manual Install

Clone the repo or copy an individual skill folder into your runtime skill directory:

• Claude Code: ~/.claude/skills/
• Codex: ~/.codex/skills/
• Gemini CLI: ~/.gemini/skills/
• GitHub Copilot: ~/.copilot/skills/

If you use both Claude and Codex, the intended runtime model is:

• install the runtime copy in ~/.claude/skills/<skill>
• point ~/.codex/skills/<skill> at that installed Claude copy

What You Get

Install Surface

The public install surface currently includes:

• implementation-brief for durable, decision-complete implementation handoffs
• prd-planner and prd-executor as explicit-only compatibility shims during the migration
• skill-manager for repo-canonical publishing, marketplace distribution, and runtime install management

Learning Surface

The docs in docs/README.md explain:

• why the starter-pack uses six core roles
• why the system stays serial by default
• why reusable skills were added instead of more global roles
• how repo refresh differs from machine install
• how research and artifact-heavy work changed the design

Available Skills

Skill	Description
implementation-brief	Create or audit a durable implementation brief for handoff across people, agents, sessions, or external systems.
prd-executor	Deprecated explicit-only compatibility shim. Approved plans now execute through native agent capabilities.
prd-planner	Deprecated explicit-only compatibility shim. Durable planning now routes to implementation-brief.
skill-manager	Manage repo-canonical skills across marketplaces and runtime installs. Publish released skills, install them into Claude, and mirror Codex to the Claude runtime copy.

Why It Is Designed This Way

The starter-pack follows a few non-default opinions:

• roles are capability boundaries, not personality labels
• durable artifacts matter more than chat memory
• validation closes work; execution alone does not
• repo-local managed files should be refreshed from canonical templates, not hand-forked
• parallelism is useful, but bounded sidecars are safer than broad swarms for most repo work

Start here for the reasoning:

• Design Principles
• Reference Docs
• Cowork Notes
• Cowork Implications
• Operating Instance Lessons
• Runtime Framework Breakdown

• docs/ is the educational surface

Public And Private Scope

This public repo intentionally publishes only generic implementation-handoff and skill-management workflows.

It does not include:

• private compatibility profiles
• private migration notes
• repo-specific validation paths
• brand-specific operating docs
• private starter-pack templates

That split is intentional. Private or machine-specific starter-pack templates live in the private marketplace.

Trust And Review

This is a curated marketplace, not an unrestricted prompt dump.

Skills added here should be:

• explicit about what they do
• safe about destructive operations
• structured so the runtime behavior can be reviewed
• portable across assistants when possible
