prompt-optimizer is an ECC agent skill that rewrites vague or weak prompts into precise, ECC-aware instructions for developers who need Claude Code or Cursor agents to execute tasks reliably on the first attempt.
About
prompt-optimizer is an ECC (Everything Claude Code) skill that turns vague or weak prompts into precise, ECC-aware instructions Claude Code or Cursor can execute reliably. It targets developers who struggle with ambiguous agent requests that produce inconsistent edits, missed constraints, or partial implementations. The skill aligns phrasing with ECC conventions so downstream agents inherit clear scope, constraints, and success criteria. Reach for prompt-optimizer before kicking off complex multi-file changes, refactors, or workflow automations where prompt quality directly affects output. The repository notes a Japanese translation is in progress; the English ECC origin skill defines the authoritative behavior.
- Analyzes raw prompts for intent, gaps, and clarity
- Matches prompts to ECC skills, commands, agents, and hooks
- Outputs a ready-to-paste optimized prompt
- Advisory role only — never executes the requested task
- Supports both English and Chinese trigger phrases

How do you write reliable prompts for Claude Code agents?
Turn vague or weak prompts into precise, ECC-aware instructions that Claude Code or Cursor can execute reliably.
Who is it for?
Developers using Claude Code or Cursor who repeatedly get inconsistent agent output from underspecified or ambiguous prompts.
Skip if: Developers who already maintain detailed PRDs, structured issue templates, or automated test-driven agent workflows with fixed schemas.
When should I use this skill?
A user's agent prompt is vague, underspecified, or failing to produce reliable Claude Code or Cursor execution.
What you get
Refined ECC-aware prompt text with explicit scope, constraints, and execution-ready instructions.
- Optimized ECC-aware prompt text
