/timeline

Generate a chronological timeline for a project or topic using sub-agents.

Usage

/timeline <project or topic>
/timeline MyDataIntegration
/timeline NewProductLine
/timeline SAP migration

Instructions

Phase 1: Planning

1. Identify the project/topic
2. Load .claude/context/projects.md for context
3. Plan to gather events from:
   • Project file (key dates, milestones)
   • Meetings (by date)
   • ADRs (decision dates)
   • Tasks (created, completed dates)
   • Daily notes (mentions)

Phase 2: Parallel Gathering (use sub-agents)

Launch sub-agents in parallel using model: "haiku" for efficiency:

Agent 1: Project Milestones (Haiku)

• Read project file
• Extract: start date, key milestones, status changes
• Return: date, event type, description

Agent 2: Meeting Timeline (Haiku)

• Search +Meetings/ for all meetings linked to project
• Extract: date, meeting title, key outcomes
• Return: chronological list

Agent 3: Decision Timeline (Haiku)

• Find ADRs related to project
• Extract: created date, status change dates, decision
• Return: decision events

Agent 4: Task Timeline (Haiku)

• Find tasks linked to project
• Extract: created date, due date, completed date
• Return: task lifecycle events

Phase 3: Compile Timeline
