memtrace-episode-replay

## Overview Replay the graph diff for **one episode** (a single git commit or working-tree save). Shows which nodes/edges were added, modified, or removed in that episode — not a multi-episode time-range narrative. Use `get_evolution(mode: "recent")` to **find** episode IDs and timestamps, then drill into a specific episode with this tool. ## Episode selector — pick one | Approach | Parameters | |---|---| | Known episode UUID | `episode_id` | | Newest episode in repo | `repo_id` + `episode_index: 0` | | Nth newest | `repo_id` + `episode_index: N` | **There is no `from` / `to` / `include_working_tree` on this tool.** ## Optional filters (large commits) | Param | Purpose | |---|---| | `symbol` | Scope to one symbol name | | `file_path` | Substring filter on record paths | | `kind` | e.g. `"Function"`, `"CALLS"` | | `mode` | `"graph_summary"` for digest on huge commits | | `compress` | default `true` — collapse identical-hash modifications | | `limit` / `cursor` | Pagination per bucket (default limit 200) | Full parameter spec for every Memtrace tool: `references/mcp-parameters.md` (bundled at the memtrace-skills plugin root). ## Steps ### 1. Find the episode to inspect From `get_evolution`: ```json { "repo_id": "memdb", "from": "7d ago", "mode": "recent", "limit": 20 } ``` Each entry has `episode` metadata including `id` (use as `episode_id`) and `reference_time`. Or use `episode_index: 0` for the newest episode without knowing the UUID. ### 2. Call `get_episode_...
