Git best practices for version control and collaboration

Records unexpected API behaviors, undocumented caveats, version bugs, or non-obvious workarounds into .claude/memory/annotations.md. Use immediately when an undocumented behavior or surprising caveat is discovered during development.

Creates a well-formed git commit following conventional commit format with type, scope, and descriptive message. Use when the user is ready to commit changes or mentions conventional commits.

Locks the codebase to prevent unintended writes during a freeze period such as before a release or during an incident. Use when the user mentions freezing, code lock, or release lockdown.

Unlocks the codebase after a release freeze or incident freeze period to resume normal development. Use when a freeze period ends or when the user mentions unfreezing or lifting the code freeze.

Calendar and scheduling management. Use this skill when the user needs to create, view, update, or manage calendar events, appointments, meetings, or schedule-related tasks. Supports ICS file format, recurring events, and timezone handling.

Export knowledge base content to PDF, Markdown, or HTML files saved under _data/exports/. Use when a user wants to save or share KB content as downloadable files. Supports exporting a single document file, a single feed entry, a single note, or the entire knowledge base.

Comprehensive toolkit for developing with the CocoIndex library. Use when users need to create data transformation pipelines (flows), write custom functions, or operate flows via CLI or API. Covers building ETL workflows for AI data processing, including embedding documents into vector databases, building knowledge graphs, creating search indexes, or processing data streams with incremental updates.
