Devkit Create Skill

Create AIWG Skill

Create a new skill that can be triggered by natural language patterns.

Understanding Skills

Skills differ from commands:

• Commands: Triggered by explicit /command-name invocation
• Skills: Triggered by natural language patterns (e.g., "apply voice", "validate writing")

Skills are ideal for:

• Capabilities users invoke conversationally
• Features that should "just work" without explicit commands
• Cross-cutting concerns that apply in many contexts

Process

1. Validate Parameters

Verify $ARGUMENTS contains:

• Skill name (kebab-case)
• --to target (addon or framework, NOT extension)

Note: Skills cannot be added to extensions because skills need standalone functionality.

Check target exists:

bashCopy code
ls ~/.local/share/ai-writing-guide/agentic/code/addons/<target>/
# or
ls ~/.local/share/ai-writing-guide/agentic/code/frameworks/<target>/

2. Interactive Design (if --interactive)

Guide the user through skill design:

Skill Purpose:

What does this skill do? (e.g., "applies voice profiles to content", "validates code quality")

Trigger Phrases:

What natural language phrases should activate this skill? Examples:

• "apply voice", "use voice", "write in voice"
• "validate code", "check quality", "review code"
• "format document", "clean up", "prettify"

Input Requirements:

What input does this skill need?

• Content to process
• Configuration parameters
• File paths

Output Format:

What does this skill produce?

• Transformed content
• Validation report
• Recommendations

Reference Materials:

Does this skill need supporting documentation?

• Style guides
• Validation rules
• Example outputs

3. Execute Scaffolding

Run the CLI scaffolding tool:

bashCopy code
node ~/.local/share/ai-writing-guide/tools/scaffolding/add-skill.mjs \
  <name> \
  --to <target>

4. Generated Structure

Copy code
<target>/skills/<name>/
├── SKILL.md           # Main skill definition
└── references/        # Supporting documentation

5. Customize SKILL.md

The generated SKILL.md needs customization.

REQUIRED frontmatter fields:

• name: — skill slug (kebab-case)
• description: — Mandatory. Used by Claude Code for NL matching and required by Codex (Codex rejects any SKILL.md without a non-empty description). Never leave this blank.
• version: — semver string (e.g., 1.0.0)
• priority: — Mandatory. Importance level: critical, high, medium, or low. Used by corpus gap reports and backlog tooling to surface work items. Never omit.

yamlCopy code
---
name: <skill-name>
description: <what this skill does — REQUIRED, non-empty>
version: 1.0.0
priority: medium
---

# <Skill Name>

## Trigger Phrases

Activate this skill when the user says:
- "<phrase 1>"
- "<phrase 2>"
- "<phrase 3>"

## Input

This skill expects:
- <input requirement 1>
- <input requirement 2>

## Execution Process

1. <Step 1>
2. <Step 2>
3. <Step 3>

## Output

This skill produces:
- <output 1>
- <output 2>

## Examples

### Example 1: <scenario>
**User**: "<example trigger>"
**Result**: <what happens>

### Example 2: <scenario>
**User**: "<example trigger>"
**Result**: <what happens>

6. Add Reference Materials

If the skill needs supporting documentation:

bashCopy code
# Create reference files
touch <target>/skills/<name>/references/style-guide.md
touch <target>/skills/<name>/references/validation-rules.md

7. Update Manifest

The CLI tool automatically updates the manifest. Verify:

jsonCopy code
{
  "skills": ["existing-skill", "<new-skill>"]
}

Output Format

Copy code
Skill Created: <name>
─────────────────────

Location: <target>/skills/<name>/

Created:
  ✓ SKILL.md
  ✓ references/

Manifest updated: <target>/manifest.json

Next Steps:
  1. Edit SKILL.md to define trigger phrases
  2. Add execution process details
  3. Create reference materials (if needed)
  4. Test with natural language triggers

Examples

bashCopy code
# Create skill in addon
/devkit-create-skill code-formatter --to aiwg-utils

# Create skill with interactive guidance
/devkit-create-skill voice-apply --to voice-framework --interactive

# Create skill in framework
/devkit-create-skill requirement-tracer --to sdlc-complete

Best Practices

1. Clear trigger phrases: Use natural, conversational language
2. Multiple triggers: Provide several ways to invoke the skill
3. Specific execution: Document exactly what happens when triggered
4. Good examples: Show realistic usage scenarios
5. Reference materials: Include supporting docs when needed
