Meta-Prompter
Prompt evaluation and optimization using the meta-prompter-mcp CLI. Returns <OPTIMIZED_PROMPT> for the caller to execute.
Inputs
Raw arguments: $ARGUMENTS
Infer from the arguments:
- CONTEXT: the task context or prompt to optimize
- OUT_DIR: output directory, or
.implement-assets/meta-prompterif not provided
Session
- If starting fresh: create SESSION_ID =
sess-YYYYMMDD-HHMMSSand use it for all files.
Execution
See references/rules.md for CLI usage, environment variables (model configuration), and error handling.
Execute all steps A through E:
A) Evaluate
- If <prompt_eval> tag doesn't exist:
1. Run: npx meta-prompter-mcp "CONTEXT" via Bash, with --model flag per references/rules.md model resolution 2. Save the JSON output to <prompt_eval> and include: - "original_prompt": "CONTEXT"
- Otherwise, skip to Clarify.
B) Clarify
- If <clarification_answers> tag is missing or incomplete:
- Read the 3 questions from <prompt_eval> - Attempt to answer all questions based on context - If you don't have enough context to answer: - Use AskUserQuestion tool to ask each question - Save the questions and answers to <clarification_answers> tag as: {"answers": [{"q": "<question1>", "answer": "<user answer>"}, {"q": "<question2>", "answer": "<user answer>"}, {"q": "<question3>", "answer": "<user answer>"}]}
C) Build PROMPT
- Proceed only when all 3 answers are present and clear.
- Build PROMPT:
- Base on rewrite from evaluation result - Append a short Clarifications section from the 3 answers (concise bullet points).
D) Re-evaluate and gate
- Think the re-evaluation process carefully
- Re-run
npx meta-prompter-mcp "<built PROMPT>"via Bash (with--modelflag per references/rules.md model resolution)
- Overwrite <prompt_eval> with this latest evaluation JSON result (preserve "original_prompt" and, if present, "contextual_prompt"). - When global < 8: - STOP execution immediately. - Do NOT invent questions. Use the 3 questions returned by this re-evaluation. - Redo B) Clarify, redo C) Build PROMPT, and re-run this step (D).
- Repeat until
global >= 8, then proceed using the <OPTIMIZED_PROMPT>. - Max 3 iterations. If
global < 8after 3 attempts, use the best-scoring prompt as <OPTIMIZED_PROMPT> and note the score.
E) Return
- If OUT_DIR is provided:
1. Run mkdir -p OUT_DIR via Bash 2. Use the Write tool to save <OPTIMIZED_PROMPT> to OUT_DIR/soul.md
- Return <OPTIMIZED_PROMPT> to the caller for execution
