**Call this IMMEDIATELY** when user says phrases like: "Let's use...", "From now on...", "Always do...", "Never do...", "I prefer...", "The standard is...", "We should always...", or confirms ANY technical approach. Also call when: (1) A design pattern is established, (2) An architectural choice is made, (3) Coding standards are discussed, (4) UI/UX conventions are agreed, (5) Technology stack decisions happen. Capture decisions DURING the conversation, not after. Focus on WHY, not just WHAT.

Permanently delete a decision and its embedding. Supports global: prefix. Consider deprecating instead if the user might want it back.

Get full details of a specific decision by ID. Use this after search_decisions returns relevant results to get complete context including rationale and constraints.

View the activity log of recent decision changes — adds, edits, deletes, and syncs.

Get a project overview: total decisions, active count, and last activity.

List all recorded decisions for the project. Use this when you need a complete overview of project conventions, or when starting work on a new feature area to understand existing patterns.
