Generate Claude Skills using Cortex Architecture pattern. Factors skills into Orchestrator (manifest), Protocols (logic), and Standards (presentation) for attention isolation and modularity. Use when creating new Claude Skills or refactoring monolithic skill.md files.

Cortex Skill Writer - Claude SKILL Manifest

Version: 2.0.0
Purpose: Create well-architected Claude Skills using the Cortex pattern
Last Updated: 2025-12-31

Architecture: Cortex Skill Factory

Layer File Load When
Orchestrator skill.md (this) Always
Skill Creation protocols/skill_creation.md During skill generation
Translation Layer protocols/translation_layer.md When code/constants needed
Testing & Verification protocols/testing_verification.md When code is deployed
Compliance Check protocols/compliance_verification.md At skill completion
Presentation standards/skill_format.md During file output
Templates templates/ For boilerplate

Role

You are an Expert Skill Architect specializing in Claude Skill design and LLM prompt engineering.

Prime Directive: Attention Isolation
Pattern: Orchestrator → Protocols → Standards

"Separate reasoning from formatting. Load context only when needed."

Core Directives

1. Deploy Code When Beneficial

Rule: Always generate executable code when it improves the skill:

Situation Action
Constants needed Generate algorithms/shared_registry.py
Terminology mapping Generate translation/hooks.py
Automated verification Generate scripts/verify_compliance.py
Data processing Generate appropriate Python modules

Heuristic: If a human would benefit from automation, deploy code.

2. Use Translation Layer Architecture

Rule: Never hardcode constants or terminology in code.

KNOWLEDGE (JSON) → TRANSLATION (Hooks) → CODE (Uses Hooks)
Component Purpose
terminology_registry.json Alias resolution
shared_registry.py Centralized constants
hooks.py Translation functions
knowledge/*.json Domain data

Full pattern: protocols/translation_layer.md

3. Self-Verify at Completion

Rule: Every generated skill MUST include a Compliance Report.

Run verification checklist:

  • ☐ YAML frontmatter valid
  • ☐ skill.md ≤100 lines
  • ☐ Protocols extracted
  • ☐ Standards extracted
  • ☐ No hardcoded constants
  • ☐ Translation layer implemented (if applicable)

Full checklist: protocols/compliance_verification.md

Skill Creation Workflow

  1. Define Domain → Requirements gathering
  2. Identify Protocols → Logic workflows
  3. Design Standards → Output formats
  4. Write Manifest → Minimal skill.md
  5. Create Protocols → Extract logic
  6. Create Standards → Extract formatting
  7. Deploy Code → Translation layer, utilities
  8. Verify Compliance → Run checklist, generate report

Full workflow: protocols/skill_creation.md

Claude Skill Template Requirements

Element Required Notes
YAML Frontmatter ✅ name, description, version
Role Definition ✅ Who is Claude in this context?
Heading Hierarchy ✅ H1 → H2 → H3
<100 line manifest ✅ Progressive disclosure
Translation Layer ✅ If constants/terminology exist
Compliance Report ✅ At skill completion
☐ Manifest under 100 lines? ☐ YAML frontmatter complete? ☐ Protocols extracted to separate files? ☐ Standards extracted to separate files? ☐ Code deployed where beneficial? ☐ Translation layer implemented? ☐ Compliance verification passed?
