speckit-agent-skills

Agent skills and generated runtime entry points for Spec Kit.

Overview

This repository tracks the current Spec Kit output together with a small set of repository-specific skills.

• Shared Agent Skills - skills/ contains the shared speckit-* skills plus repository-specific skills. Claude Code uses them through .claude/skills, while Codex CLI uses them through .agents/skills.
• Cursor Agent - Spec Kit-generated skills live in .cursor/skills/.
• GitHub Copilot CLI - Spec Kit-generated agents and prompt wrappers live in .github/agents/ and .github/prompts/.
• OpenCode - Spec Kit-generated commands live in .opencode/commands/.
• Gemini CLI - .gemini/commands/ remains checked in, but Gemini is not part of the current CI regeneration set.
• Spec Kit infrastructure - .specify/ contains integration state, manifests, scripts, and templates used by the generated skills and commands.

The tracked Spec Kit version is recorded in VERSION.md. CI checks the latest Spec Kit release and regenerates outputs only when that version changes.

Current integration model

The repository CI currently runs specify init --integration for:

• codex
• agy
• cursor-agent
• copilot
• opencode
• claude

The generated files are therefore not all stored in the same layout:

Legacy layouts such as .claude/commands/, .codex/prompts/, and .opencode/command/ are intentionally not maintained.

Quickstart

1. Clone this repository.

   git clone https://github.com/dceoy/speckit-agent-skills.git
   cd speckit-agent-skills
   

2. Install Spec Kit.

3. Initialize a target project with the Spec Kit integration appropriate for your agent.

   specify init --here --integration <integration>
   

4. If the target runtime consumes Agent Skills directly, copy the required skills from skills/ into that project’s skills directory when needed.

   cp -a skills/* /path/to/project/skills/
   

5. Invoke the relevant speckit-* skill or runtime command from your agent.

Spec Kit workflow

The main Spec-Driven Development flow in this repository is:

1. Constitution - Define project principles.
2. Specify - Capture requirements for new work.
   • Or Baseline - Derive a specification from an existing codebase.
3. Clarify (optional) - Resolve material ambiguities.
4. Plan - Produce the implementation strategy.
5. Tasks - Generate ordered work items.
6. Analyze (optional) - Check consistency across the specification, plan, and tasks.
7. Converge (optional) - Compare an existing implementation with the spec/plan/tasks and append remaining work to tasks.md.
8. Implement - Execute the tasks.

Additional utilities include Checklist for requirements-quality checks and Tasks to Issues for converting generated tasks into GitHub issues.

Skills

Spec Kit skills

The current shared speckit-* set includes:

• speckit-analyze
• speckit-baseline
• speckit-checklist
• speckit-clarify
• speckit-constitution
• speckit-converge
• speckit-implement
• speckit-plan
• speckit-specify
• speckit-tasks
• speckit-taskstoissues

Most Spec Kit-managed skills are tracked by the manifests in .specify/integrations/. speckit-baseline is a repository-specific skill for deriving specifications from existing code.

Utility skills

• claude-command-converter - Repository-specific utility for converting Claude command content into Agent Skill format.

Regeneration

.github/workflows/ci.yml calls .github/workflows/speckit-init.yml. The workflow:

1. resolves the latest Spec Kit release,
2. records specify --version in VERSION.md,
3. skips regeneration when VERSION.md is unchanged,
4. runs specify init --force --here --ignore-agent-tools --script sh --integration for the configured integrations,
5. formats generated Markdown and JSON, and
6. opens or updates a pull request when the tracked Spec Kit version changes.

Treat manifest-managed runtime files as generated output. Prefer changing the integration configuration or repository-specific skills instead of manually maintaining generated copies.

Prerequisites

Install and authenticate only the runtime tools you intend to use, plus Spec Kit itself.

• Claude Code - Uses .claude/skills.
• OpenAI Codex CLI - Uses .agents/skills.
• Cursor Agent - Uses .cursor/skills/.
• GitHub Copilot CLI - Uses .github/agents/ and .github/prompts/.
• OpenCode - Uses .opencode/commands/.
• Gemini CLI - Can use the checked-in .gemini/commands/, but those files are outside the current regeneration set.
• Spec Kit - Install from github.com/github/spec-kit.

Usage notes

• Skills do not always auto-run; use the runtime’s skill invocation flow or request the skill explicitly.
• If a skill fails, inspect its SKILL.md and verify the required Spec Kit project structure and prerequisites.
• Run Spec Kit helper scripts from the repository root and prefer their structured output modes such as --json when available.
• Do not restore legacy runtime layouts unless a currently supported Spec Kit integration starts generating them again.
