What problem does it solve? Documentation drifts out of sync with code after every commit, ADR, or schema change, and stale docs silently mislead readers. This Skill enforces a disciplined update workflow where every factual claim about the running system carries a verifiable evidence citation, corrections are recorded as amendments, and each change is logged in a project ledger. ## Core Features & Use Cases - Diátaxis placement gates: Decides exactly where new or changed text belongs (tutorial, how-to, reference, explanation, work record, or ADR) using ordered falsification gates. - Evidence-backed claims: Requires every statement about the running system to carry an evidence=<path>:<line> marker that is re-opened and verified before completion. - Trust and amendment system: Resolves untrusted spans in edited blocks (capped at 2 per task) and records corrections in an amendment table naming what was false. - Ledger recording: Appends each change to a documentation ledger and regenerates projections such as changelog, index, and frontmatter version fields. - Use Case: After a PR changes an API's behavior, run this Skill to locate the affected reference page, rewrite the stale claims with verified evidence lines, add an amendment row, and record the update in the ledger. ## Quick Start Update the documentation to reflect the changes in my latest commit, placing the text correctly and citing evidence for every claim.
