pi-prompt-coach — on-demand prompt improvement

Use /improve when a rough request would benefit from clearer structure:

/improve fix the failing workflow on main

The command:

1. probes the current repository for bounded facts such as branch, changed-file names, latest commit, and relevant CI status;
2. asks the local Gemma4 model at Docker Model Runner to rewrite the request;
3. asks TypeSafe whether the rewrite preserves the original intent; and
4. submits the verified rewrite as the next real user message.

The rewrite is never shown in a separate editor and ordinary input is never intercepted. If Gemma4 is unavailable, the rewrite is malformed, TypeSafe cannot verify it, or intent confidence is below the threshold, /improve sends the original prompt unchanged.

With no argument, /improve uses the most recent user prompt in the session:

/improve

Configuration

The local request includes the prompt, working directory, and names-only probe facts. TypeSafe receives the original prompt, local rewrite, and those same bounded facts. Decision entries are stored in the session but do not enter LLM context.
