pr-describerlisted

# PR describer Runs the bundled nanoodle workflow `workflows/pr-describe.noodle-graph.json` against the NanoGPT API — a three-stage text pipeline over one input (`Diff`): a drafter writes a conventional PR body (summary, `## Changes`, `## Test plan`), an auditor compares the draft against the raw diff and lists every breaking change, behavioral shift, or touched file the draft omits, and a reviser emits the final markdown (`Final PR body`) with every audit finding folded in (adding `## Breaking changes` when needed). Requires Node.js >= 20 and the `nanoodle` npm package (`npx nanoodle` fetches it). ## API key The run needs a NanoGPT API key. Use whichever is available: - `NANOGPT_API_KEY` already set in the environment — prefer this; no extra flags. - A `.env` file containing `NANOGPT_API_KEY=...` — pass `--env-file <path>` only when the key is not already in the environment. (With this CLI, `--env-file` overrides ambient `NANOGPT_API_KEY`.) Never print the key. ## Run From this skill's directory (or prefix paths if running from elsewhere). Write the branch diff to a `.txt` file first (`@path` reads `.txt`/`.md` files as text): ```sh npx nanoodle run workflows/pr-describe.noodle-graph.json \ --input "Diff=@/tmp/pr-diff.txt" ``` Producing the diff file is the usual one-liner, e.g. `git diff origin/main...HEAD > /tmp/pr-diff.txt`. The output is text, so no `--out` directory is needed. Pipe the body straight into GitHub: ```sh npx nanoodle run workflows/pr-descr
