What's inside
- Skill name
prompt-engineering- Description
- Write strong prompts for LLMs — direct model calls, single tool-using agents, and multi-agent systems. Covers the core stance (specificity and completeness over brevity), prompt anatomy and ordering, the high-leverage techniques (be specific, give context and the why, positive instructions, multishot examples, let the model think, XML tags, system/role prompts, output formats and structured outputs, prompt chaining, guardrails), how prompting changes across execution modes (direct call vs single agent vs orchestrator vs worker), and iterating empirically with evals. Use when authoring, reviewing, or debugging a prompt or system prompt for any LLM feature or agent.
