Meta-skill for improving and optimizing prompts using Anthropic's prompt engineering best practices. Provides the 4-step improvement workflow (example identification, initial draft, chain of thought refinement, example enhancement), keyword registries for documentation lookup, and decision trees for improvement strategies. Use when improving prompts, optimizing for accuracy, adding chain of thought reasoning, structuring with XML tags, enhancing examples, or iterating on prompt quality. Delegates to docs-management skill for official prompt engineering documentation.

Instructions

# Prompt Improvement

## MANDATORY: Query Official Documentation First

> **STOP - Before improving ANY prompt, you MUST invoke the docs-management skill.**
>
> This is NOT optional guidance - it is a required execution step.

### Required: Query Documentation via docs-management Skill

**Invoke the `claude-ecosystem:docs-management` skill BEFORE making any improvements:**

Search for relevant documentation using natural language:

- Primary query: "prompt engineering chain of thought XML tags"
- Read the top results returned by the skill

### Why Documentation Query is Required

- **Training data is stale** - Your knowledge may be outdated
- **Official docs are canonical** - Anthropic's current best practices
- **Prevents hallucination** - Ground improvements in real documentation
- **Ensures accuracy** - Latest Claude 4.x guidance

### Recommended Query Topics

Query at least ONE of these topics based on your improvement needs:

- **Chain of thought:** "chain of thought thinking tags reasoning"
- **XML structure:** "XML tags structure prompts formatting"
- **Examples/multishot:** "multishot prompting examples few-shot"
- **Claude 4.x best practices:** "Claude 4 prompting best practices"

### Verification Checkpoint

Before improving a prompt, verify:

- [ ] Did I invoke the docs-management skill? (not just read about it)
- [ ] Did I receive documentation from docs-management?
- [ ] Did I READ at least one official doc returned by the skill?
- [ ] Are my improvements based on what I read from official docs?

**If ANY checkbox is unchecked, STOP and invoke the docs-management skill first.**

## Overview

This meta-skill replicates Anthropic's Console/Workbench prompt improver functionality within Claude Code. It provides workflows, patterns, and keyword registries to transform basic prompts into high-performance structured templates.

**What this skill provides:**

- The 4-step improvement workflow (quick reference)
- Keyword registry for docs-management queries
- D
