01What can it help you accomplish?
Capture and search long-term memory across DeepSeek Harness sessions
Searchable local memory of completed main-agent turns plus a Memory UI under DSH Settings → StrataGate-AgentMemory
DeepSeek Harness (dsh) users running long-lived agents who need persistent, source-traced cross-session memory
02How to install into DeepSeek Harness
Prerequisites
- DeepSeek Harness (dsh) must already be installed
Installation steps
- 01
$ dsh plugin --profile web add stratagate-dsh
- 02
Restart that profile, then keep using DSH normally.
Verify the integration
- StrataGate exposes its Memory UI under DSH Settings → StrataGate-AgentMemory
03DSH integration and capability boundaries
Installed as a native DeepSeek Harness (dsh) plugin — `dsh plugin --profile <name> add stratagate-dsh`
Automatic local-first capture
completed main-agent conversations and tool results→local SQLite database (no separate memory server)
Layered / compact memory
recent and older history→detailed recent history plus a compact index that expands on demand
Event cards with source & time
lasting memory records→records origin and separates when something was mentioned from when it happened
Hybrid BM25 + structured search
memory graph / events→compact facts via searchEvents() / searchGraphNodes() with reciprocal-rank fusion
Evidence-gated recall
retrieved context→a sufficiency check (evidence refs) before the agent relies on memory
External memory import
structured memory exported by another AI→traceable Events while the imported source text remains preserved
04Who is it for? When not to use it?
Good for
- DeepSeek Harness (dsh) users running long-lived agents who need persistent, source-traced cross-session memory
Not for
- The current version still has 31 majority-wrong questions on its evaluation set, so recalled answers are not guaranteed correct — verify important recalls against the cited source.
05Compatibility, maintenance and safety notes
- The current version still has 31 majority-wrong questions on its evaluation set, so recalled answers are not guaranteed correct — verify important recalls against the cited source.
- StrataGate supplies state, constraints and validation, but the integrating application still controls model calls, tool iteration and the maximum retrieval budget.

06Frequently asked questions
How do I install StrataGate AgentMemory in DeepSeek Harness?
If DeepSeek Harness is already installed, add it to your profile with `dsh plugin --profile web add stratagate-dsh`, then restart that profile. StrataGate then captures completed main-agent turns and shows its Memory UI under DSH Settings → StrataGate-AgentMemory.
Where is my memory stored?
By default the database is at `DSH_HOME/stratagate/memory.db` in a local SQLite file. There is no separate memory server, and removing the plugin does not delete the database.
How does StrataGate avoid answering from weak evidence?
Between retrieval and answering it inserts a fixed protocol that judges sufficiency from evidence refs; if evidence is incomplete it changes strategy, expands an event, or inspects the source before answering.
Can I import memory from another AI tool?
Yes. Structured memory exported by another AI can become traceable Events while the imported source text remains preserved, so provenance is kept.
Is it safe to rely on the recalled answers?
Not guaranteed. The current version still has 31 majority-wrong questions on its evaluation set, so verify important recalls against the cited source before trusting them.
