Writing Skills

Writing Skills

Create skills that integrate with EC and follow cogitation conventions.

Announce: "I'm using the writing-skills skill to create a new skill."

The Structure

Every skill needs a SKILL.md file in cogitation/skills/<skill-name>/:

---
name: skill-name
description: [Third person verb] what it does. Mentions EC integration. Use when [trigger conditions].
---

# Skill Title

Brief description.

**Announce:** "I'm using the skill-name skill to [action]."

## Step 0: Load Context

ec_search for relevant config/patterns/learnings.

## Instructions
[Clear, step-by-step guidance with EC integration]

## Store Learnings
[When and how to store memories]

## References
[Link to other skills with @notation]

Naming Conventions

• Gerund form preferred: debugging, verifying, writing-plans
• Lowercase with hyphens: requesting-review, not RequestingReview
• Max 64 characters
• No reserved words: anthropic, claude

Description Rules

1. Third person - "Provides...", "Creates...", "Handles..."
2. What + When - What it does AND when to use it
3. Mention EC - Note the EC integration
4. Include trigger words - Keywords users would naturally say
5. Max 1024 characters

Good:

description: Provides systematic debugging workflow that finds root cause before fixing. Searches EC for prior issues and stores learnings. Use when encountering bugs, test failures, or unexpected behavior.

Bad:

description: Use this for debugging

Content Guidelines

• Under 500 lines - Split into separate files if longer
• Concise - Claude is smart, don't over-explain
• Use @notation - Reference other skills: @tdd, @verifying
• Include announcement - "I'm using the X skill to..."
• Provide examples - Concrete, not abstract

EC Integration Requirements

Every cogitation skill MUST integrate with EC. Include:

Step 0: Load Context

## Step 0: Load Context

Get project config and relevant memories:

\`\`\`
ec_search:
  query: project config
  type: config

ec_search:
  query: [relevant area]
  type: pattern|learning|decision
\`\`\`

Store Learnings Section

## Store Learnings

If [condition worth storing]:

\`\`\`
ec_add:
  type: learning|pattern|decision
  area: [component]
  content: [What to remember]
  rationale: [Why it matters]
\`\`\`

Skill References

Use @skill-name to reference other skills:

• In headings: ## Phase 4: Fix @tdd
• In text: Use @verifying before claiming success
• In handoffs: If yes → **Use @finishing-branch**

Progressive Disclosure

For complex skills, use separate files:

my-skill/
├── SKILL.md          # Overview (< 500 lines)
├── reference.md      # Detailed docs (loaded when needed)
└── examples.md       # Usage examples

Reference in SKILL.md:

For detailed API reference, see [reference.md](reference.md)

After Creating

1. Test with a real task
2. Verify EC integration works
3. Check @references resolve
4. Iterate based on usage

Store New Skill Pattern

After creating a new skill:

ec_add:
  type: pattern
  area: cogitation
  content: Created skill [name] for [purpose]. Key pattern: [main workflow].
  rationale: Extends cogitation capabilities
