meta-prompter（元提示器）

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-prompter if not provided

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 "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 --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 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
