Claude Command Converter

Convert Claude Code commands to standard Agent Skills format for portability across AI coding assistants.

When to Use

• Migrating existing .claude/commands/*.md files to skills/*/SKILL.md format.
• Creating portable skills from Claude Code-specific commands.
• Standardizing command definitions for use with Claude Code, Codex CLI, GitHub Copilot, and other runtimes.

Inputs

• Source command file path (e.g., .claude/commands/my-command.md).
• Optional: target skill name (defaults to command filename without extension).

If input is missing, ask for the source command file path.

## When to Use

- Scenario 1

## Inputs

- Required input 1
- Optional input 2

## Workflow

## Outputs

- Output file 1
- Output file 2

Conversion Workflow

1. Read the source command from .claude/commands/.
2. Extract metadata:

- description from YAML frontmatter. - handoffs for related skills/next steps. - $ARGUMENTS handling for inputs.

1. Determine skill name:

- Convert command.name.md → command-name (replace dots with hyphens). - Use kebab-case for multi-word names.

1. Create skill directory: skills/<skill-name>/
2. Transform content to SKILL.md format:

- Frontmatter: Keep name and description only. - Enhance description: Expand to include when to use the skill. - Convert $ARGUMENTS: Document as Inputs section. - Structure workflow: Extract steps into numbered Workflow section. - Add "When to Use": Derive from command context and description. - Add "Outputs": List generated files/artifacts. - Convert handoffs: Add "Next Steps" section referencing related skills.

1. Remove runtime-specific content:

- Remove ## User Input section with $ARGUMENTS block. - Remove handoffs from frontmatter (move to prose). - Remove /command.name references (use skill names instead).

1. Validate skill structure:

- Frontmatter has name and description only. - Body has clear sections (When to Use, Inputs, Workflow, Outputs). - No TODO placeholders remain. - No runtime-specific variables like $ARGUMENTS.

1. Report conversion result:

- Source command path. - Generated skill path. - Key transformations applied. - Manual review recommendations.

Transformation Rules

Example Conversion

Input: .claude/commands/speckit.specify.md

---
description: Create feature specification from natural language.
handoffs:
  - label: Build Technical Plan
    agent: speckit.plan
---
## User Input

\`\`\`text
$ARGUMENTS
\`\`\`

The text the user typed after `/speckit.specify`...

Output: skills/speckit-specify/SKILL.md

---
name: speckit-specify
description: Create or update a feature specification from a natural language feature description.
---

# Spec Kit Specify Skill

## When to Use

- The user wants a new or updated feature spec from a natural language description.

## Inputs

- Feature description from the user.
- Repo context with `.specify/` scripts and templates.

If the description is missing or unclear, ask a targeted question before continuing.

## Workflow

...

## Outputs

- `specs/<feature>/spec.md`
- `specs/<feature>/checklists/requirements.md`

## Next Steps

After generating spec.md:

- **Plan** technical implementation with speckit-plan.
- **Clarify** specification requirements with speckit-clarify.

Key Rules

• Preserve all workflow logic and instructions.
• Remove runtime-specific constructs ($ARGUMENTS, handoffs, /slash-commands).
• Expand terse descriptions to include usage triggers.
• Use imperative voice in workflow steps.
• Keep skills self-contained and portable.
• Don't add extraneous documentation files (README, CHANGELOG, etc.).

Next Steps

After conversion:

• Review generated SKILL.md for completeness.
• Delete unused example files in scripts/, references/, assets/.
• Update AGENTS.md/CLAUDE.md skill inventory if applicable.
• Create symlinks for runtime integration if needed.
