<essential_principles>
Skills are modular, filesystem-based capabilities that provide domain expertise on demand. This skill teaches how to create effective skills.
All prompting best practices apply. Be clear, be direct, use XML structure. Assume Claude is smart - only add context Claude doesn't have.
When a skill is invoked, Claude reads SKILL.md. Use this guarantee:
skill-name/
├── SKILL.md # Router + principles
├── workflows/ # Step-by-step procedures (FOLLOW)
├── references/ # Domain knowledge (READ)
├── templates/ # Output structures (COPY + FILL)
└── scripts/ # Reusable code (EXECUTE)
SKILL.md asks "what do you want to do?" → routes to workflow → workflow specifies which references to read.
When to use each folder:
No markdown headings (#, ##, ###) in skill body. Use semantic XML tags:
...
...
...
Keep markdown formatting within content (bold, lists, code blocks).
SKILL.md under 500 lines. Split detailed content into reference files. Load only what's needed for the current workflow. </essential_principles>
Wait for response before proceeding.
Progressive disclosure for option 1 (create):
Progressive disclosure for option 3 (add component):
Intent-based routing (if user provides clear intent without selecting menu):
After reading the workflow, follow it exactly.

Simple skill (single file):
---
name: skill-name
description: What it does and when to use it.
---
<objective>What this skill does</objective>
<quick_start>Immediate actionable guidance</quick_start>
<process>Step-by-step procedure</process>
<success_criteria>How to know it worked</success_criteria>
Complex skill (router pattern):
SKILL.md:
<essential_principles> - Always applies
<intake> - Question to ask
<routing> - Maps answers to workflows
workflows/:
<required_reading> - Which refs to load
<process> - Steps
<success_criteria> - Done when...
references/:
Domain knowledge, patterns, examples
templates/:
Output structures Claude copies and fills
(plans, specs, configs, documents)
scripts/:
Executable code Claude runs as-is
(deploy, setup, API calls, data processing)

<success_criteria> A well-structured skill:
GitHub CLI operations for issues, PRs, reviews, CI, and Copilot workflows. Use when working with pull requests, issues, CI status, code review, GitHub Copilot, triage, or PR shipping.
Creates and navigates hierarchical code maps (L0/L1/L2/L3) for AI agent and human orientation. Use when bootstrapping codebase understanding, creating navigation documentation, exploring architecture, or validating map integrity.
Reusable development patterns and guides for AI-assisted workflows. Use when asking about CLI design for agents, CLI location, config discovery, vault, commenting standards, snapshot testing, credential storage, Python project architecture, semantic zoom, skill writing, Claude tools, agent teams, extracting deterministic work, plugin authoring and distribution, beads/dolt setup, or showboat/rodney/chartroom agent documentation.
