/gsd history

Shows a log of completed execution units — tasks, slices, and milestones — with metadata about how they ran. Useful for reviewing what happened, tracking costs, and debugging performance.

Usage

/gsd history
/gsd history 20
/gsd history --cost
/gsd history --phase
/gsd history --model

Argument	Effect
N	Show the last N entries (default varies)
--cost	Include token cost breakdown per unit
--phase	Filter or group by execution phase
--model	Show which model was used for each unit

Flags can be combined: /gsd history --cost --model 10 shows the last 10 entries with cost and model info.

What It Shows

Each entry includes:

• Unit ID — the milestone/slice/task identifier
• Timing — when it started and how long it took
• Phase — research, plan, execute, complete, etc.
• Model — which LLM model handled the unit
• Cost — token usage and estimated cost (with --cost)
