session-history

name: session-history description: Show what happened in recent past sessions on this project as a clean timeline. Use when the user asks "what did we do last time", "session history", "past sessions", or wants an overview of previous work. user-invocable: true

The user wants an overview of recent sessions on this project.

Quick start

memory_sessions { "limit": 20 }

Expected output:

7f3a9c2 · app · 2026-06-07 09:00 · completed · 14 obs
  - decision: Rotate refresh tokens on every use
b21d004 · app · 2026-06-05 14:00 · completed · 9 obs
  - code: limit.ts counts per-IP

Why

Only show sessions and observations the tool returned. An empty history is a real answer, never a cue to invent past work.

Workflow

Call memory_sessions with limit: 20 for a meaningful window.
Present in reverse chronological order: session id (first 8), project, start time, status.
For sessions with observations, show the key highlights (type plus title).
Note the total observation count per session.
When a session summary exists, surface its title and the key decisions.

Anti-patterns

WRONG: the tool returns two sessions, you describe "several sessions of steady progress" and add ones you remember from the conversation.

RIGHT: show exactly the two sessions returned, each with its real id, status, and observation count.

Checklist

Every session shown came from the tool response.
Order is reverse-chronological.
Per-session observation counts match the response.
No session or highlight was invented or merged.

Troubleshooting

See ../_shared/TROUBLESHOOTING.md if memory_sessions is not available.
