Prompt-writing guidance: task contracts, examples, structure, chaining, structured output, agent autonomy, tool descriptions, prompt-injection boundaries, and evaluation, with a prompt-reviewer stage. Use whenever an LLM prompt, system prompt, subagent instruction, or tool description is written, improved, or reviewed, including prompts embedded in application or bot code. Skill files use skill-master.

# Prompt Master

Treat a prompt as a clear task contract. Add information that changes the result; do not add a
technique merely because it is common in prompt-engineering guides.

## Prompt Essentials

A prompt should communicate the applicable parts of:

- the task and required result;
- context the model cannot infer but needs to perform the task correctly;
- real constraints and the reasons behind non-obvious requirements;
- criteria that distinguish an acceptable result;
- the response format when it matters to the user or a downstream system.
