Creating Prompts

Process

Step 1: Plan the Prompt

Before creating, answer:

1. What specific task does this prompt accomplish?
2. Will this task be repeated by multiple people?
3. Does it need scripts/assets, or is it instruction-based?
4. What is the clearest kebab-case name? (e.g., migrate-stencil-to-lit, generate-vitest-tests)

Decision:

• Needs scripts/assets → Create a skill instead
• Fully autonomous → Create an agent instead
• User-invoked workflow → Create a prompt

Step 2: Initialize

node .github/skills/creating-prompts/scripts/init_prompt.mjs {name}

Creates: .github/prompts/{name}.prompt.md with template structure.

Step 3: Complete the Prompt

Fill in the generated file:

1. Set agent (usually 'agent' for ui-kit)
2. Set tools (common: ['codebase', 'editFiles', 'search'])
3. Write role definition (specific expertise)
4. Add task description with {{placeholders}}
5. List numbered requirements (specific, actionable)
6. Include validation checklist

For format details, see SPECIFICATION.md. For writing guidance, see best-practices.md. For examples, see ui-kit-templates.md.

Step 4: Validate

node .github/skills/creating-prompts/scripts/validate_prompt.mjs .github/prompts/{name}.prompt.md

Step 5: Test with Real Use Case

1. Invoke the prompt in VS Code Copilot
2. Provide test input with real values for placeholders
3. Review output quality against requirements
4. Refine prompt based on gaps or errors

Modifying Existing Prompts

Extending:

1. Read existing prompt to understand scope
2. Add new requirements or validation checks
3. Run validation, test with use cases

Renaming:

1. Create new file with new name
2. Copy content, update internal references
3. Search for references: grep -r "{old-name}" .github/
4. Update references, delete old file

Deprecating:

1. Add to description: "(Deprecated: use replacement-prompt instead)"
2. Keep functional until dependents migrate
3. Delete after confirming no references
