Author a crit story with crit story

This is a sibling skill to the interactive Crit review loop — it does not run inside /crit. Invoke it deliberately only when the user explicitly asks for story generation; do not infer it from generic review, PR, or diff-review requests.

Primary path: author in-session with --guide / --prep / --story-file (do not run bare crit story, which spends agent_cmd tokens).

Step 1: Fetch the guide

crit story --guide

This prints the resolved authoring guide (the user's customized version if they have one — always invoke this at runtime rather than reusing this skill's own prose) followed by --- and the JSON schema for the fields you must emit. Read and follow that guide's principles and JSON shape exactly — it is the source of truth, not this file.

Step 2: Write the prep file

crit story --prep /tmp/crit-story-prep.txt

This writes the full, untrimmed diff (commit messages + every hunk with its (file_path, old_start) id) to the given path and prints the path. Read that file — the diff is never inlined into the guide prompt.

Step 3: Author the story JSON

Following the guide from Step 1, cluster hunks by theme (not by file) and write a JSON object with only prologue, chapters, and support to a temp file, e.g. /tmp/crit-story.json. Do not include version, generated_at, agent, base_sha, head_sha, scope_fingerprint, or coverage — crit fills those in.

Step 4: Ingest

crit story --story-file /tmp/crit-story.json

Exit 0 means the story was saved (crit opens the browser to show it). Exit 1 means it was rejected — the coverage report (missing/duplicated hunks) is printed to stdout as JSON on every attempt, success or failure. If rejected:

• duplicated non-empty: a hunk is claimed by two chapters (or a chapter and support). Decide where it belongs and re-ingest.
• missing non-empty with auto_repaired: true on exit 0: crit already back-filled the omissions into support[]. Optionally re-author to place them deliberately.
• A drift error ("diff changed since prep"): re-run crit story --prep and re-author from the fresh prep file.

What this skill does NOT do

• It does not call crit comment, crit push, or crit share — those are separate flows.
• It does not produce review-level human comments.
• It does not run as part of the generic Crit review loop.
• It does not run bare crit story (LLM via agent_cmd) unless the user explicitly asks for that path.
