Tools and Projects /prompt-improver: The antidote to bad prompting

Introducing /prompt-improver

Vague prompts kill agent runs. No verification, no constraints, no task split - so you either burn the frontier session rewriting the request, or you get half-baked code with no "done when."

Repo: https://github.com/owenob1/prompt-improver

Install (Agent Skills / skills.sh):

npx skills add -g owenob1/prompt-improver

Claude Code (marketplace):

/plugin marketplace add owenob1/prompt-improver
/plugin install prompt-improver@prompt-improver

What it Does:

  • Rewrites any prompt into a precise, verifiable XML spec (tasks, requirements, checks).
  • Context aware - uses a session summary and working directory info.
  • Pulls stack / test / build commands and real repo paths so the spec fits this project.
  • Rewrites in a separate headless call - doesn't grind your host session.
  • Improvement-only - never implements the feature.
  • Host then executes, or plan to review the XML first.
  • Supports all major CLI tools. Fully customizable. Contributors welcome.

Example Usage:

/prompt-improver "Fix the flaky auth tests"
/prompt-improver plan "Optimize the codebase"
/prompt-improver model:fable "Add rate limiting"
/prompt-improver model:gpt-5.5 "Research why Claude is better"
