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:

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

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.
