prompt-improver skillA
prompt-improver is agent-read markdown (skill) from owenob1/prompt-improver: 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 spec.
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns 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" ``` …
