What problem does it solve? User-facing changes to the PolyKybd firmware or host software (new HID commands, polyctl subcommands, settings, keyboard features, languages) silently drift out of sync with the public documentation site, leaving pages wrong or new capabilities undocumented. ## Core Features & Use Cases - Feature-to-page mapping: Routes each change type (HID protocol, polyctl CLI, host settings, keyboard features, languages) to the exact docs page that must be updated, including sidebar registration in astro.config.mjs. - Cross-repo PR workflow: Guides creating a separate branch and PR in the polykybd-docs repo, keeping docs changes out of firmware/host PRs. - Verification pipeline: Provides link-integrity checks and an Astro build procedure, including a fallback for sharp install failures and rules for image handling. - Use Case: After bumping PROTOCOL_VERSION and adding a HID command in the firmware, use this Skill to update the command table and version history in reference/hid-protocol.mdx, verify the build, and open a companion docs PR. ## Quick Start Update the PolyKybd docs site to cover the new polyctl subcommand I just added and open a PR in the polykybd-docs repo.
