dsh-task-checklist

A local task checklist plugin for DeepSeek Harness. It lets an Agent create tasks, filter them by state or tag, mark work complete, and export a clean Markdown checklist.

All task data stays in the current working directory under .dsh/task-checklist/tasks.json. The plugin does not send task data over the network.

Quick install

Requirements

You need Node.js 22 or newer, pnpm, and a DeepSeek Harness installation that supports JavaScript or TypeScript plugins.

Step 1: Download and build

Copy and run:

git clone https://github.com/fff122/dsh-task-checklist.git
cd dsh-task-checklist
pnpm install
pnpm build

Step 2: Create the plugin configuration

Run this command from the repository root:

cat > task-checklist.patch.yml <<EOF
- insert:
    - id: dsh-task-checklist
      name: '$PWD/dist/src/index.js'
EOF

The plugin path is absolute because the Harness patch loader requires an absolute path.

Step 3: Start Harness with the plugin

If Harness is installed as a command:

dsh web --patch "$PWD/task-checklist.patch.yml"

Otherwise, run:

npx @deepseek-ai/dsh web --patch "$PWD/task-checklist.patch.yml"

Verify the installation

Ask the Agent:

创建一个任务：准备周五的项目演示。标签用 work 和 demo，优先级为 high。

If the plugin is loaded, the Agent can use task_create. You can then ask it to list unfinished tasks, complete a task by id, or export a Markdown checklist.

Data and behavior

Each Harness working directory has its own checklist at .dsh/task-checklist/tasks.json. Writes are atomic, so an interrupted write cannot leave a partially written data file. Task identifiers are returned by task_create and task_list; use them with task_complete.

The tag filter is an all tags filter. For example, filtering by work and demo returns only tasks that have both tags.

Updating the plugin

From the cloned repository:

git pull
pnpm install
pnpm build

Restart Harness with the same patch command after rebuilding.

Development

Run the complete package quality gate from the repository root:

pnpm run format:check
pnpm run typecheck
pnpm run test
pnpm run build

The implementation is deliberately separated into small modules:

src/
  index.ts        # Harness entry point and tool registration
  task-schema.ts  # Task types and input normalization
  task-store.ts   # Local persistence, filtering, completion, and export

test/
  index.test.ts
  mount.test.ts
  task-schema.test.ts
  task-store.test.ts
