What it does

Creates, optimizes, and iteratively refines agent prompts, system prompts, developer prompts, and reusable prompt templates. Use when asked to improve a prompt, optimize a system prompt, rewrite an agent prompt, tune prompt wording, make a prompt more reliable, port prompts between OpenAI, Claude, or Gemini, or build prompt evals.

Prompt Optimizer

Optimize prompts with evals. Keep every instruction, example, and external context reference causal.

Step 1: Capture Contract

Record before editing:

  • task type: new, refine, port, or debug
  • target model family and snapshot, if known
  • prompt surface: system, developer, user, tool descriptions, examples, schemas
  • layer owners: platform, deployer/persona, retrieved context, user payload
  • objective and non-goals
  • inputs, tools, and external files available
  • required output shape
  • success criteria and failure cases
  • hard constraints: latency, verbosity, safety, budget, tool use, style

If success criteria or examples are missing, create a small eval set first. If the bottleneck is model choice, retrieval, tool schema, or missing evals, say so before rewriting.

Step 2: Inventory External Context

For repo or agent prompts, list stable context by exact path:

Context typeExamples
Agent rulesAGENTS.md, CLAUDE.md
Specsspecs/*.md, docs/api.md
PoliciesSECURITY.md, docs/releasing.md
Examplesexamples/, tests/fixtures/

Rules:

  • Reference stable files by repo-relative path instead of copying them.
  • Paste only excerpts needed for the prompt or eval case.
  • Mark whether a file is loaded, referenced, or out of scope.
  • Avoid vague context pointers such as "read the docs".
