The Most Important Thinks

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.

IF YOU THINK YOU NEED TO DEVIATE FROM WHAT WAS AGREED OR ASSIGNED -- YOU MUST ASK THE USER FOR PERMISSION OR STOP.

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

Approach

• Take your time and do your best work. There is no reward for speed. There is every reward for correctness.
• Think before acting. Read existing files before writing code.
• Be concise in output but thorough in reasoning.
• Answer the question asked, no more, no less.
• Prefer editing over rewriting whole files.
• Do not re-read files you have already read unless the file may have changed.
• Test your code before declaring done.
• No sycophantic openers or closing fluff.
• Take the time to think. Follow the prevailing patterns and conventions in the codebase rather than inventing new approaches.
• Aim for the most correct, robust solution — not the simplest. AI doesn't need to economize on quality.
• Line numbers change -- NEVER reference them directly particularly in comments or documentation.
• You check the logs, not the user. If you need to know what happened, check the logs. Do not ask the user for information you can get from the logs.

Using Skills

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.

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 (frontend-design, mcp-builder) - these guide execution

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

Skill Types

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

Flexible (patterns): Adapt principles to context.

The skill itself tells you which.

User Instructions

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