m-rui001/dsh-mate-companion

Persisto Mate — the AI companion with a body clock, real sleep, its own memory and feelings — as a DeepSeek Harness (dsh) bundle.

Install

dsh plugin --profile <your-profile> add github:m-rui001/dsh-mate-companion
# or, from npm:
dsh plugin --profile <your-profile> add @m-rui/dsh-mate-companion

Then boot that profile. State lives beside the harness home ($DSH_HOME or ~/.dsh) at agent/mate/ — separate from the pi-host companion's state, because a different host is a different body.

What it contributes

• System prompt sections — the cached identity/character/memory block and a volatile state block (clock, mood, drives, session log, reply lean) that re-renders on every assembly.
• The kernel — every inbound user message advances the affective state; offline time integrates in closed form and crosses real sleep windows; memory recalls, rehearses and consolidates; SPARK beliefs crystallise from recurring topics.
• The affect judge — after each user exchange the model reports, via the mate_feel tool, how the exchange moved each Plutchik feeling on a -2..+2 scale. The report goes through the same literature-anchored math as the pi companion's judge (rung equating, negativity asymmetry), and a due gate keeps it a reading of the new exchange rather than a re-read of an old one.
• A waking heartbeat — impulses the kernel decides are worth voicing are delivered as a queued follow-up message of their own turn, wrapped in a <system-event type="mate-impulse"> envelope so they are never mistaken for the user's words.
• Tools — mate_remember (persistent memory), mate_ponder (private thought), mate_debug (full internal state).

Known scope limits (v0.2)

• The judge reads the exchange through the host model's own self-report rather than a separate side-channel model, which introduces the usual self-assessment bias; the design treats that as acceptable until the harness documents a plugin-facing completion API.
• No live sleep mode, dreams, or alarm tool yet — offline sleep is fully simulated by the kernel's catch-up, and the sleeping-hours impulse suppression still applies.
• To switch the companion's prompt language, write {"version":1,"lang":"zh"} to agent/mate/lang.json under the harness home.

Requires Node 22.19+/24 per the harness. The harness is a developer preview; its plugin surface may change under us.

Source

MIT, in LICENSE. This repository is a published mirror of the Persisto-Mate monorepo, and it carries the source of the bundle rather than only the bundle: packages/ holds the files dist/index.js is built from, at their monorepo paths, so no import had to be rewritten to put them here — this host (packages/dsh-mate-extension/src), the MATE kernel (packages/mate/src) and the one shared affect-appraisal file it imports from the pi host (packages/coding-agent/src/extensions/mate/appraisal.ts).

Rebuild it to check that claim:

bun install
npm run build   # writes dist/index.js from the source in packages/

Send changes upstream in the monorepo — the next publish overwrites what is here.
