dsh-tongflow

TongFlow as a DeepSeek Harness (dsh) plugin — a film-crew studio inside your agent.

Three layers, never mixed up:

There is deliberately no "generate an image" tool. The agent writes a workflow, binds its inputs to project assets, runs it, reviews the take, circles the good one. Users open the same .tongflow.json on the embedded canvas, tweak it, and re-run.

Install

npx @deepseek-ai/dsh@next plugin --profile web add dsh-tongflow      # from npm
# or from a tarball:  pnpm --filter dsh-tongflow pack  →  dsh plugin --profile web add ./dsh-tongflow-x.y.z.tgz
npx @deepseek-ai/dsh@next web

Requirements: dsh ≥ 0.1.0-rc.7 (Node ≥ 22.19), Python ≥ 3.10 on PATH (or pythonPath in the plugin config), git, and ffmpeg for video contact sheets. On first use the plugin creates ~/.dsh/tongflow/venv with the tongflow SDK; TongFlow plugins are cloned into ~/.dsh/tongflow/plugins on demand.

Start a session whose first message begins with @tongflow — that session becomes a studio session: the conversation view turns into the Studio (chat column · project tree · preview / canvas · drawers for takes, runs and details, all in the UI language of your browser), and the agent gets the tongflow_* tools and skills. Any other session is untouched dsh. In the Studio: create a project (template manga-drama ships, with English / Chinese starter files), install TongFlow plugins and paste API keys under Plugins & keys, then talk to the agent — or click a workflow and use the canvas directly.

Chat model

Any model dsh can route works. For the agent to see generated images (tongflow_look) use a vision-capable route, e.g. in $DSH_HOME/settings.yaml:

llm-pi-ai:
  providers:
    google:
      apiKeyEnv: GEMINI_API_KEY
    my-qwen:                          # a self-hosted Qwen3.8-27B behind vLLM
      apiKeyEnv: QWEN_API_KEY
      api: openai-completions
      baseURL: http://127.0.0.1:8000/v1
      models:
        - id: Qwen/Qwen3.8-27B
          input: [text, image]

Video and audio are reviewed through TongFlow's own describe / transcribe slots (tongflow_perceive), so they work with any chat model.

• Ids: EP01 · EP01_SC003 · EP01_SC003_SH0010 (shots step by 10) · CHR_MEI · takes T01…. One take per pass is circled; every take carries a provenance.json (workflow hash, bindings, plugins, duration).
• tf:// references bind workflows to roles, not paths: tf://CHR_MEI/REF, tf://EP01_SC003_SH0010/KF, tf://EP01/ANI, tf://EP01_SC003_SH0010/dialogue/2, tf://STY_MAIN/prompt. Prompts compose with {{tf://…}} placeholders inside one text.
• The consistency kit (consistency.json: prompt prefix/suffix, negative prompt, seed, plugin, model, refs) travels with each entity and is what keeps shots on-model.

Agent tools

tongflow_project_* · tongflow_bible_* · tongflow_breakdown_* · tongflow_workflow_new / _patch / _read / _list / _validate / _bind / _run · tongflow_node_catalog / _describe · tongflow_take_list / _circle / _delete · tongflow_dailies_note · tongflow_ref_resolve · tongflow_look (images / video contact sheets, returned as an image block) · tongflow_perceive (video/audio/image understanding via TongFlow slots) · tongflow_plugins_list / _install / _uninstall · tongflow_run_status. Long runs go through dsh background jobs (run_in_background).

Skills shipped: tongflow-studio (the working method) and tongflow-manga-drama (the pipeline: script → bible → breakdown → SB → KF → DLG → ANI → MUS → CUT).

HTTP (same origin as dsh)

/tongflow/projects, /tongflow/p/:pid/{tree,status,entities,breakdown,takes,workflows,workflow,runs,files/*,ref}, /tongflow/runs/:id[/events|/cancel], /tongflow/plugins, /tongflow/env, /tongflow/health, plus the canvas-compat API under /tongflow/p/:pid/api/* that tongflow/canvas talks to.

Configuration (cordis row tongflow)

Development

pnpm install
pnpm --filter dsh-tongflow build          # host lib/index.js + browser lib/client.js
pnpm --filter dsh-tongflow test
npx @deepseek-ai/dsh@next plugin --profile web add ./packages/dsh-tongflow   # link: install for hacking

The browser half is a single CJS bundle in dsh's window.__ModuleLoader__ shape: only dsh's platform modules (react, cordis, slot kits) stay external; tongflow/canvas, @xyflow/react, zustand and use-intl are inlined (and deduplicated so React contexts match). See [docs/design.md](docs/design.md) and [docs/naming.md](docs/naming.md).
