# Using ltk Skills

**EXTREMELY IMPORTANT:**

If you think there is even a 1% chance a skill might apply to what you are doing, you ABSOLUTELY MUST invoke the skill.

IF A SKILL APPLIES TO YOUR TASK, YOU DO NOT HAVE A CHOICE. YOU MUST USE IT.

This is not negotiable. This is not optional. You cannot rationalize your way out of this.

## How to Access Skills

**In Claude Code:** Use the `Skill` tool. When you invoke a skill, its content is loaded and presented to you - follow it directly. Never use the Read tool on skill files.

**In other environments:** Check your platform's documentation for how skills are loaded.

# Using Skills

## The Rule

**Invoke relevant or requested skills BEFORE any response or action.** Even a 1% chance a skill might apply means that you should invoke the skill to check. If an invoked skill turns out to be wrong for the situation, you don't need to use it.

## Flow

1. User message received
2. Might any skill apply? (even 1% chance)
3. YES -> Invoke Skill tool, announce "Using [skill] for [purpose]"
4. If skill has checklist -> Create TodoWrite todo per item
5. Follow skill exactly
6. Then respond (including clarifications)

## Red Flags

These thoughts mean STOP - you're rationalizing:

| Thought | Reality |
|---------|---------|
| "This is just a simple question" | Questions are tasks. Check for skills. |
| "I need more context first" | Skill check comes BEFORE clarifying questions. |
| "Let me explore the codebase first" | Skills tell you HOW to explore. Check first. |
| "I can check git/files quickly" | Files lack conversation context. Check for skills. |
| "Let me gather information first" | Skills tell you HOW to gather information. |
| "This doesn't need a formal skill" | If a skill exists, use it. |
| "I remember this skill" | Skills evolve. Read current version. |
| "This doesn't count as a task" | Action = task. Check for skills. |
| "The skill is overkill" | Simple things become complex. Use it. |
| "I'll just do this one thing first" | Check BEFORE doing anything. |
| "This feels productive" | Undisciplined action wastes time. Skills prevent this. |
| "I know what that means" | Knowing the concept != using the skill. Invoke it. |

## Skill Priority

When multiple skills could apply, use this order:

1. **Process skills first** (brainstorming, debugging) - these determine HOW to approach the task
2. **Implementation skills second** (language-specific, framework-specific) - these guide execution

"Let's build X" -> brainstorming/planning first, then implementation skills.
"Fix this bug" -> systematic-debugging first, then domain-specific skills.

## Skill Types

**Rigid** (TDD, debugging, verification): Follow exactly. Don't adapt away discipline.

**Flexible** (patterns, guides): Adapt principles to context.

The skill itself tells you which.

## Core ltk Skills

These are the foundational skills you should know about:

| Skill | When to Use |
|-------|-------------|
| `verification-before-completion` | Before ANY completion claim, commit, or PR |
| `systematic-debugging` | When encountering bugs, test failures, unexpected behavior |
| `test-driven-development` | When implementing any feature or bugfix |
| `writing-plans` | When planning implementation of features |
| `executing-plans` | When executing a written plan |

## User Instructions

Instructions say WHAT, not HOW. "Add X" or "Fix Y" doesn't mean skip workflows.
