dsh-plugin-longgraph

English · 简体中文

Community DeepSeek Harness plugin that registers the longgraph authoring
skills on ctx.skills.

Community plugin. Not affiliated with or maintained by DeepSeek AI.

This package is DeepSeek Harness only. It does not install or launch
nodes on any other product.

longgraph is a prompt
library for long-horizon agent work: an executor node, a ledger, and a
clean-context supervisor connected by a one-way directives edge. Each
node owns one timer. There is no wake edge between them. This plugin
does not add an agent runtime — it exposes that library through the
Harness skill seam.

Skills

After the plugin loads, ctx.skills.list() / snapshot() advertise:

Name	Role
longgraph	Fit check, then hand off to loop-graph
loop-graph	Interview → compile .longgraph/<date-slug>/ → launch or print DSH prompts
loop-converge	Code-convergence preset, then the same compile

get / the model-facing skill({ name }) path returns the full instruction
body. resourceBase points at the packaged skill directory so templates
and references/deepseek-harness.md
resolve.

Install

DeepSeek Harness is in developer preview. This plugin pins
@deepseek-ai/dsh-skill >=0.1.0-rc.5 <0.2.0 and is tested against
the public 0.1.0-rc.6 line.

Profile bundle (recommended)

dsh plugin --profile web add github:levi-qiao/dsh-plugin-longgraph
dsh --profile web

Then invoke skill({ name: "longgraph" }) (or loop-graph /
loop-converge).

package.json declares dsh.bundle.patch. The shipped
cordis.patch.yml inserts one row named dsh-plugin-longgraph. Profile
composition applies that layer before the profile's own patch.

Pin a git commit when you want a frozen install:

dsh plugin --profile web add github:levi-qiao/dsh-plugin-longgraph#<commit>

Git installs fetch source, so prepare runs tsdown. With pnpm 10+, add
the package to the profile pnpm-workspace.yaml build allowlist if pnpm
blocks prepare, then retry.

Direct Cordis row

- id: longgraph-skills
  name: dsh-plugin-longgraph

The plugin injects skills and calls ctx.skills.registerProvider.
It has no runtime config.

Timers on DeepSeek Harness

Two independent root sessions, two schedule_create clocks:

• every_seconds floor is 300 (five minutes).
• Schedule is session-local — both sessions must stay live.
• A busy session waits until idle, then followup(). The timer does not
  interrupt a fire.
• Never followup() / inject() the other session. The executor reads
  new directives on its next fire.

See the host reference.

Compatibility

Peer	Range
@deepseek-ai/cordis	>=4.0.1 <5
@deepseek-ai/dsh-skill	>=0.1.0-rc.5 <0.2.0

Harness remains a developer preview. Compatibility-breaking changes will
require a new plugin version.

Development

pnpm install
pnpm typecheck
pnpm test
pnpm build
pnpm integration

pnpm test loads the shipped apply against a real @deepseek-ai/dsh-skill
SkillRegistry and reads the packaged SKILL.md files. pnpm integration
boots the same plugin through the public Cordis Loader.

What this is not

• Not a DeepSeek AI product and not an official Harness bundle.
• Not a replacement for dsh-agent-loop, Schedule, Jobs, or the Web UI.
• Not a multi-host skill pack. The sibling
  longgraph-skill repo
  remains the multi-host prompt library.
