A guide for creating and improving Claude Code Skills. Skills are folders of instructions that give an AI agent specialised knowledge when needed.

In plain words
What is it for?
Use it to write SKILL.md files, organise workflows and reference material, create templates, and refine existing skills.
Why use it?
It helps keep skill instructions clear, reusable, and organised so agents can follow the right guidance for each task.

About the project

TÂCHES Claude Code Resources is a collection of custom commands, skills, and agents that structure Claude Code workflows such as planning, debugging, automation, and subagent creation. It is intended for developers who use Claude Code for real software projects. The catalogue entries are examples of the resources included in the collection.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

create-agent-skills scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How Skills Work

Skills are modular, filesystem-based capabilities that provide domain expertise on demand. This skill teaches how to create effective skills.

1. Skills Are Prompts

All prompting best practices apply. Be clear, be direct, use XML structure. Assume Claude is smart - only add context Claude doesn't have.

2. SKILL.md Is Always Loaded

When a skill is invoked, Claude reads SKILL.md. Use this guarantee:

  • Essential principles go in SKILL.md (can't be skipped)
  • Workflow-specific content goes in workflows/
  • Reusable knowledge goes in references/

3. Router Pattern for Complex Skills

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:

  • workflows/ - Multi-step procedures Claude follows
  • references/ - Domain knowledge Claude reads for context
  • templates/ - Consistent output structures Claude copies and fills (plans, specs, configs)
  • scripts/ - Executable code Claude runs as-is (deploy, setup, API calls)

4. Pure XML Structure

No markdown headings (#, ##, ###) in skill body. Use semantic XML tags:

<objective>...</objective>
<process>...</process>
<success_criteria>...</success_criteria>

Keep markdown formatting within content (bold, lists, code blocks).

5. Progressive Disclosure

SKILL.md under 500 lines. Split detailed content into reference files. Load only what's needed for the current workflow. </essential_principles>

  1. Create new skill
  2. Audit/modify existing skill
  3. Add component (workflow/reference/template/script)
  4. Get guidance

Wait for response before proceeding.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

create-agent-skills is a skill published in the GitHub repository glittercowboy/taches-cc-resources (1,977 stars, last pushed 5mo ago), licensed MIT. It adds 46 tokens to every session and 1,545 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
