Duc01226 Easyplatform Skill Create

[IMPORTANT] Use TaskCreate to break ALL work into small tasks BEFORE starting.

Shared Protocol Duplication Policy — Inline protocol content in skills (wrapped in <!-- SYNC:tag -->) is INTENTIONAL duplication. Do NOT extract, deduplicate, or replace with file references. AI compliance drops significantly when protocols are behind file-read indirection. To update: edit .claude/skills/shared/sync-inline-versions.md first, then grep SYNC:protocol-name and update all occurrences.

Output Quality — Token efficiency without sacrificing quality.

1. No inventories/counts — AI can grep | wc -l. Counts go stale instantly
2. No directory trees — AI can glob/ls. Use 1-line path conventions
3. No TOCs — AI reads linearly. TOC wastes tokens
4. No examples that repeat what rules say — one example only if non-obvious
5. Lead with answer, not reasoning. Skip filler words and preamble
6. Sacrifice grammar for concision in reports
7. Unresolved questions at end, if any

Quick Summary

Goal: Create new Claude Code skills with proper structure or scan/fix invalid skill headers across the catalog.

Workflow:

1. Clarify — Gather purpose, trigger keywords, tools needed via AskUserQuestion
2. Check Existing — Glob for similar skills, avoid duplication
3. Scaffold — Create directory + SKILL.md with frontmatter + Quick Summary
4. Add SYNC blocks — Include relevant protocol checklists from sync-inline-versions.md
5. Validate — Run frontmatter + header validation
6. Enhance — Call /prompt-enhance on the new SKILL.md for attention anchoring quality

Key Rules:

• Every SKILL.md MUST ATTENTION include ## Quick Summary (Goal/Workflow/Key Rules) within first 30 lines
• Single-line description with [Category] prefix and trigger keywords
• SKILL.md under 500 lines; use references/ for detail
• Shared protocols MUST ATTENTION be inlined via <!-- SYNC:tag --> blocks, NEVER file references
• MUST ATTENTION call /prompt-enhance on new/updated skills as final quality pass

Modes

SKILL.md Schema Reference

Frontmatter Fields (all optional)

---
name: my-skill # Lowercase, hyphens. Max 64 chars. Default: directory name.
description: '[Category] What it does. Triggers on: keyword1, keyword2.' # MUST ATTENTION be single-line
argument-hint: '[issue-number]' # Autocomplete hint for arguments
disable-model-invocation: false # true = user-only (/name), Claude cannot auto-invoke
user-invocable: true # false = hidden from / menu, Claude-only auto-invoke
context: inline # inline (default) or fork (isolated subagent)
agent: general-purpose # Subagent type when context: fork
model: opus-4-5 # Model override. Default: session model
allowed-tools: 'Read, Grep, Glob' # Comma-separated tool restrictions
version: 1.0.0 # Project convention (non-official)

Invocation Control Matrix

Variable Substitution

Key Rules

• Single-line description (multi-line YAML breaks catalog parsing)
• Include trigger keywords in description for auto-activation
• Use [Category] prefix (e.g., [Frontend], [Planning], [AI & Tools])
• SKILL.md under 500 lines; use references/ for detail
• Descriptions loaded at 2% of context window (~16,000 chars)
• Include "ultrathink" in skill content to enable extended thinking mode

Mode 1: Create Skill

Workflow

1. Clarify — If requirements unclear, use AskUserQuestion for: purpose, auto vs user-invoked, trigger keywords, tools needed
2. Check Existing — Glob .claude/skills/*/SKILL.md for similar skills. Avoid duplication.
3. Create Directory — .claude/skills/{skill-name}/SKILL.md
4. Write Frontmatter — Follow schema from ## SKILL.md Schema Reference section above
5. Write Instructions — Concise, actionable, progressive disclosure
6. Add SYNC Blocks — Identify which shared protocols apply to this skill. Read .claude/skills/shared/sync-inline-versions.md and copy relevant <!-- SYNC:tag --> blocks inline. Common protocols: understand-code-first, evidence-based-reasoning, output-quality-principles
7. Add Closing Reminders — Echo top rules at bottom with :reminder SYNC blocks for recency anchoring
8. Add References — Move detailed docs to references/ directory if content >200 lines
9. Add Scripts — Create scripts/ for executable helpers if needed
10. Validate — Run frontmatter validation (see Mode 2 single-file check)
11. Enhance — Call /prompt-enhance on the finished SKILL.md for AI attention anchoring quality

Frontmatter Template

---
name: { kebab-case-name }
description: '[Category] What it does. Triggers on: keyword1, keyword2.'

Skill Attention Structure (MUST ATTENTION follow)

[Frontmatter]
[SYNC protocol blocks — top attention zone]
[## Quick Summary — Goal/Workflow/Key Rules]
[Detailed instructions — middle zone]
[## Closing Reminders — bottom attention zone with :reminder SYNC blocks]

Why: AI attention is strongest at TOP and BOTTOM (primacy-recency effect). Place critical rules in both zones. See /prompt-enhance for research-backed principles.

SYNC Tag Protocol for New Skills

1. Read .claude/skills/shared/sync-inline-versions.md — canonical source for all protocol checklists
2. Identify which protocols the skill needs (e.g., investigation skills need understand-code-first + evidence-based-reasoning)
3. Copy the checklist content between <!-- SYNC:tag --> open/close tags at the TOP of the skill
4. Add 1-line :reminder versions at the BOTTOM inside Closing Reminders
5. NEVER use MUST ATTENTION READ shared/ file references — always inline

Rules

• SKILL.md is instructions, not documentation. Teach Claude HOW to do the task.
• Single-line description (multi-line YAML breaks catalog parsing)
• Description must include trigger keywords for auto-activation
• Use [Category] prefix in description (e.g., [Frontend], [Planning], [AI & Tools])
• Keep SKILL.md under 500 lines; use references/ for detail
• Progressive disclosure: frontmatter → SKILL.md summary → reference files
• Token efficiency: every line must earn its place

Mode 2: Scan & Fix Invalid Skills

What It Validates

Scan Workflow

1. Discover — Glob .claude/skills/*/SKILL.md for all skills
2. Parse — Read first 20 lines of each file, extract frontmatter
3. Validate — Check each rule above
4. Report — List issues grouped by severity (Error > Warning > Info)
5. Fix — If user confirms, fix Error-level issues automatically

Validate Script

node .claude/skills/skill-create/scripts/validate-skills.cjs          # Report only
node .claude/skills/skill-create/scripts/validate-skills.cjs --fix    # Report + auto-fix

Requirements
