Transform vague prompts into precise, verifiable structured XML prompts that coding agents execute reliably. Modes: execute (default — generate then run) and plan (generate XML for review first). Use when the user says improve prompt, make this work better, prompt engineer, structure a request, plan a complex change before coding, or when a rough request needs verification criteria before execution. Do not use when the input is already a well-structured XML prompt or detailed implementation…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# prompt-improver Turn rough user intent into high-quality, executable XML specifications via a **headless generator** (improvement-only), then execute or review that result in the host agent. ## Modes and per-prompt flags Leading tokens (like `plan`) are stripped before treating the rest as the raw request. Order does not matter; both may appear. | Token | Effect | |-------|--------| | *(none)* | **Execute** — headless-generate, brief plan, host executes | | `plan` | **Plan** — headless-generate, show XML, wait for decision | | `model:<id>` or `model=<id>` | Override generator model **for this run only** | Examples: ```text /prompt-improver "Fix the flaky auth tests" /prompt-improver plan "Fix the flaky auth tests" /prompt-improver model:fable "Fix the flaky auth tests" /prompt-improver plan model:gpt-6-sol "Refactor payments" ``` …

How to install
mdr add owenob1/prompt-improver/prompt-improver@sha256:72b7008fdb7a2e6fThe line at the top of this page pins the label v1.1.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
