dsh-memories
Dual-ledger cross-session memory for DeepSeek Harness.
Inspired by the memory pipeline of OpenAI's open-source Codex agent, dsh-memories gives every new session in a project two living ledgers:
| Ledger | File | Answers |
|---|---|---|
| Long-term facts | .dsh/memories/MEMORY.md |
"What are this project's conventions, the user's preferences, past pitfalls?" |
| Project progress | .dsh/memories/PROGRESS.md |
"Where are we? What's done? What's in progress? What's next?" |
Both are maintained automatically and recalled into the system context of every new conversation — no re-briefing required.
Features
- Automatic extraction — on each new session (throttled to once per 30 minutes), recent sessions from the same workspace (last 14 days, up to 2 per run) are summarized by an LLM into:
- stable facts in four fixed categories: preference / project / environment / lesson
- progress movements: completed / doing / next
- Strict no-op gate — one-off task details, code dumps, and secrets are never recorded; sessions with nothing worth keeping produce nothing.
- LLM consolidation — drafts are merged and rewritten into clean, deduplicated, sectioned ledgers (with automatic
.bakbackups). - Recall injection — ledger contents ride along in the system prompt of every new session (inline when small, with a file pointer when large).
- Decay — consolidation drops stale entries (30 days unconfirmed) unless marked
pinned. - Model tools & slash commands —
remember/update_progresstools let the agent write proactively;/remember,/progress,/memoriesgive humans direct control. - Failure-safe — LLM failures leave no trace in state; affected sessions are retried automatically next round.
Requirements
A DeepSeek Harness deployment that provides the standard host-plane services:
fs · llm · sessionQuery · systemPrompt · tools · commands · sandboxPolicy
(all ship with the default dsh-base bundle; tested on dsh 0.1.0-rc.9)
Install
Option 0 — one line via dsh plugin add (recommended)
dsh plugin --profile web add dsh-memories
The plugin manager reads this repo's bundled `cordis.patch.yml) and wires everything for you. Needs a release that ships the bundle manifest -- the current npm 0.1.2 predates it, so until the next publish, use Option A.
Option A — npm package into your profile
cd ~/.dsh/profiles/web # or whichever profile you run
npm install <git-url-or-tarball> # places dsh-memories into ./node_modules
Then append a row to ~/.dsh/profiles/web/cordis.patch.yml. Reference the entry file by relative path — the proven pattern in pnpm-managed profiles (bare package names in patch rows are not reliably resolved):
- insert:
- id: dsh-memories
name: './node_modules/dsh-memories/lib/index.js'
Alternatively, register it npm-natively: add "dsh-memories": "*" to the profile package.json dependencies, add "dsh-memories" to dsh.profile.bundles, run pnpm install, and skip the patch row entirely.
Option B — copy the folder
Copy this repository folder into ~/.dsh/profiles/web/node_modules/dsh-memories, then add the same patch row as above.
Restart DSH once. Done — the plugin loads at boot and works silently afterwards.
If you previously ran this capability as a dynamic plugin (
cordis_define/mem-*), remove it before restart to avoid duplicate tool registrations.
Usage
You normally do nothing. For direct control:
| Command / Tool | Effect |
|---|---|
/remember <fact> |
Append a fact to the current project's ledger and trigger consolidation |
/memories |
Status: processed count, draft files, ledger previews, last error |
/memories rescan |
Force a fresh extraction pass now |
/memories reset |
Clear the "processed" registry so recent sessions get re-read |
/progress |
Show PROGRESS.md |
/progress <note> |
Append a progress note manually |
model tool remember(fact, category?, pinned?) |
The agent saves a durable fact mid-conversation |
model tool update_progress(completed?, doing?, next?) |
The agent updates the progress ledger at milestones |

How it works
new session ──▶ scan (same-workspace sessions, ≤14 days, ≤2/run)
│
▼
extract (one LLM call per session)
├─ facts[] → raw/<session>.md
└─ progress{} → raw/_progress.md
│
▼
consolidate (one LLM call per ledger)
├─ MEMORY.md ← merge + dedupe + decay(30d) + sections
└─ PROGRESS.md ← 已完成 / 进行中 / 下一步 + dates
│
▼
next session ◀── recall section injected into system prompt
The extraction prompt enforces a strict schema (JSON array / NONE), caps entry length, forbids secrets, and skips trivial transcripts (<400 chars). Consolidation prompts enforce section formats and size budgets (≤100 lines for facts, ≤60 for progress).
Limitations & roadmap
- Project-scoped — each workspace keeps its own ledgers. A global user-level ledger (like Codex's
~/.codex/memories) is planned via aglobalDirsetting. - Extraction reads only message text (no tool payloads).
- Progress consolidation is instructed — not guaranteed — to respect the 60-line budget.
- Chinese-oriented prompts today; English variants welcome via PR.
