Cross-session memory for DeepSeek Harness (DSH).
A DSH session loses its context the moment it ends. Come back to the same project tomorrow and you explain the environment again, and rediscover how you worked around that error last time. This plugin writes that kind of information to files on disk and pulls it back when a later session needs it.
Memory has three layers: an index, environment facts, and task experience. The L1 / L2 / L3 labels in the tool list below refer to those three.
Once installed, you just tell the agent.
The build command for this project is ```pnpm build && pnpm test~~, and the tests take about forty seconds. Remember that.
It writes the line into the memory store. Open a fresh session the next day and say "run the tests for me", and the command is already known.
It works the other way too. If you forget the flags a service needs, ask the agent to look them up in memory instead of scrolling back through old chats.
dsh plugin --profile web add github:DDDFXYqiming/dsh-layered-memory
The plugin creates its directories and template files under <home>/.dsh/memory.
The agent decides when to read and write memory. The plugin registers one memory skill and 14 tools. Under progressive mode those tools stay hidden until the agent calls memory_activate once.
| Tool | Purpose |
|---|---|
memory_list | List all memory (L2 facts + L3 sops + pending + L1 chars/budget) |
memory_read | Read one entry (index / fact topic / sop filename) with provenance meta and related links; oversized entries return an outline plus head/tail excerpts, with full and from_line/to_line for the rest |
memory_search | BM25 full-text search over facts, sops and archived entries |
memory_write | Write a memory (fact/sop, evidence required, name collision snapshots the old version; evidence is quoted line by line and suspected secrets in it are redacted; plain-text secrets in the body are refused) |
memory_index | Rebuild the L1 index auto-segment, keeping the [RULES] manual segment |
memory_pending | List distilled candidates (fail-then-retry sequences) |
memory_accept | Promote a pending candidate into a real entry |
memory_update | Update an entry, keeping a history snapshot (body and provenance meta snapshotted together); new measurements can pass sourceSession/sourceSeqs, wording-only edits inherit the original source |
memory_archive | Archive an entry (hidden from L1 and memory_read, file stays in place, still searchable, current version snapshotted first); unarchive: true restores visibility |
memory_rollback | Roll back to the most recent .history/ snapshot (body and provenance meta restored together) |
memory_expand | Expand the original events behind sourceSession / sourceSeqs |
memory_stats | Counts for L2 / L3 / pending / archived and total size |
memory_maintain | Merge same-name duplicate sections, exact/near-duplicate candidates, index audit, stats, merge candidates, cold-entry review |
memory_promote | Promote project-local experience to the global namespace |

You can back it up, commit it, or edit it by hand. The body refuses text that looks like a plaintext secret; suspected secrets in evidence and related links are redacted on write.
