showbook

Use after opening a PR whose diff touches UI. Captures targeted Playwright screenshots for web changes AND for mobile changes (Expo Web bundle), embeds inline before/after for every touched surface into the PR body, and additionally triggers the label-gated native Maestro workflow for mobile diffs. Invoked by the creating-prs skill.

Use after committing changes that need to ship. Pushes the branch, opens the PR via the GitHub MCP tools, subscribes to PR activity so CI failures stream back, and (when the diff touches UI) hands off to the pr-screenshots skill so the PR description gets visual review material inline.

Use when investigating production issues in the showbook stack — errors in prod, failed pg-boss jobs, regressions only seen in prod, missing daily digest, "is X working in prod", or "prod is broken" reports. Covers Axiom log queries via APL, the read-only `/api/admin/sql` endpoint for prod DB introspection, and the docker logs fallback.

Use when fixing a bug in the showbook codebase. Verifies locally without running E2E (which is slow/flaky in the sandbox), then opens a PR and subscribes to CI activity so E2E failures from GitHub Actions can be triaged and patched in-loop.
