Use when the user asks \"what did we do last time\", \"session history\", \"past sessions\", or wants an overview of previous work.\nuser-invocable: true\n---\n\nThe user wants an overview of recent sessions on this project.\n\n## Quick start\n\n```json\nmemory_sessions { \"limit\": 20 }\n```\n\nExpected output:\n\n```text\n7f3a9c2 · app · 2026-06-07 09:00 · completed · 14 obs\n  - decision: Rotate refresh tokens on every use\nb21d004 · app · 2026-06-05 14:00 · completed · 9 obs\n  - code: limit.ts counts per-IP\n```\n\n## Why\n\nOnly show sessions and observations the tool returned. An empty history is a\nreal answer, never a cue to invent past work.\n\n## Workflow\n\n1. Call `memory_sessions` with `limit: 20` for a meaningful window.\n2. Present in reverse chronological order: session id (first 8), project, start\n   time, status.\n3. For sessions with observations, show the key highlights (type plus title).\n4. Note the total observation count per session.\n5. When a session summary exists, surface its title and the key decisions.\n\n## Anti-patterns\n\nWRONG: the tool returns two sessions, you describe \"several sessions of steady\nprogress\" and add ones you remember from the conversation.\n\nRIGHT: show exactly the two sessions returned, each with its real id, status, and\nobservation count.\n\n## Checklist\n\n- Every session shown came from the tool response.\n- Order is reverse-chronological.\n- Per-session observation counts match the response.\n- No session or highlight was invented or merged.\n\n## See also\n\n- `recap`: same data grouped by date with highlights.\n- `handoff`: jump straight into the most recent session.\n- `recall`: search across all sessions by topic.\n\n## Troubleshooting\n\nSee ../_shared/TROUBLESHOOTING.md if `memory_sessions` is not available.\n"
