Meta-Prompter

Prompt evaluation and optimization using the meta-prompter-mcp CLI. Returns <OPTIMIZED_PROMPT> for the caller to execute.

Arguments

• $ARGUMENTS[0] — The prompt to evaluate and optimize
• $ARGUMENTS[1] — OUT_DIR (optional). If provided, the OPTIMIZED_PROMPT is persisted to OUT_DIR/output.md.

Session

• If starting fresh: create SESSION_ID = sess-YYYYMMDD-HHMMSS and 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 "$ARGUMENTS" via Bash, with --model flag per references/rules.md model resolution
  2. Save the JSON output to <prompt_eval> and include:
     • “original_prompt”: “$ARGUMENTS”
• 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 --model flag 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 < 8 after 3 attempts, use the best-scoring prompt as <OPTIMIZED_PROMPT> and note the score.

E) Return

• If $ARGUMENTS[1] (OUT_DIR) is provided:
  1. Run mkdir -p $ARGUMENTS[1] via Bash
  2. Use the Write tool to save <OPTIMIZED_PROMPT> to $ARGUMENTS[1]/output.md
• Return <OPTIMIZED_PROMPT> to the caller for execution
