session-history 3

Brings the session history of nineteen other coding agents into DeepSeek Harness: recall, session digest and per-file history tools over a local index, plus optional automatic recall before each step.

DeepSeek Harness plugin: cross-session memory for the model. Full-text search all past sessions (SQLite FTS5 via ctx.sessionQuery) and bring the strongest matching excerpts back into the current context — recall earlier decisions, commands, and mistakes.

Keeps a malformed token-usage sample from taking a whole session history down with it: a missing or non-numeric counter becomes zero before the harness adds it up, so the fold never yields NaN and already-broken sessions open again.
