What problem does it solve? Devbook repositories accumulate broken metadata references, malformed meta blocks, and stale _meta indexes that fail CI checks, and this Skill diagnoses each reported problem and repairs it in the source chapters. ## Core Features & Use Cases - Schema Checking: Runs node .devbook/_tools/devbook-meta/build.mjs --check to parse every chapter and report unresolved references and schema violations with exit codes. - Guided Repair: Maps each reported symptom — dangling references, missing meta blocks, duplicate numbers, bad status or type values, malformed annotations — to the correct fix in the authored Markdown. - CI Triage: Explains why CI can fail when local checks pass, such as references breaking only in the merge result of two clean branches. - Use Case: When a pull request fails the devbook-meta check, run this Skill to identify the broken related reference, repoint it at the renamed chapter, and re-run the check until it exits 0. ## Quick Start Run devbook validate on this repository and fix every broken reference and malformed meta block the check reports.
