dsh-memory

Durable cross-session memory for DeepSeek Harness.

The harness ships no memory plugin. Its extension-cookbook names the mechanism — a prompt section plus tools — but nothing implements it, so every session starts blank. This package fills that gap with one local SQLite file: no embedding service, no API key, no sidecar process.

Install

dsh plugin --profile web add dsh-memory

The shipped bundle row stores memories at $DSH_HOME/memory/memory.db, shared by every profile on the machine.

What it gives the model

Tool	Purpose
memory_write	Store one self-contained durable fact, optionally tagged and pinned
memory_search	Keyword search over memory text and tags
memory_forget	Delete a memory that is now wrong or obsolete

Plus a memory:recall prompt section that renders pinned memories first, then the most recently updated, under a character budget. Recall therefore does not depend on the model remembering to search — what it stored is already in front of it, and search is for anything older than the budget allows.

The memory_write description steers the model away from the common failure modes: transient task state (that is what the todo list is for), secrets, and facts the repository already records.

Configuration

- id: memory
  name: dsh-memory
  config:
    path: !!js dshHomePath('memory/memory.db')
    promptRecentCount: 10
    promptMaxChars: 2000
    maxTextChars: 2000
    searchLimitDefault: 10
    searchLimitMax: 50
    promptOrder: 50

Field	Default	Meaning
path	— (required)	SQLite file, or :memory: for an ephemeral store
promptRecentCount	10	Unpinned recent memories offered to the prompt section
promptMaxChars	2000	Budget for the rendered section; overflow is reported as a count, and pinned memories are emitted first so they survive a tight budget
