Anno for DeepSeek Harness (native)

@philmingdao/anno-dsh-native is a native DeepSeek Harness plugin for Anno — a local-first HTML review, editing, and annotation workspace for coding agents.

Unlike @philmingdao/anno-dsh, which bridges the MCP server through the official DSH MCP client, this package runs Anno in-process: the local review HTTP server, the on-disk session store, and the six html_review_* model tools all live inside the Harness process. There is no MCP layer, no child npx process, and no separate server to launch.

What it provides

• A loopback-only HTTP review server (127.0.0.1, ephemeral port).

• Persistent review sessions under $ANNO_DATA_DIR (default ~/.anno/sessions); the source file is never overwritten and outputs are versioned (-reviewed.html, -reviewed-v2.html, …).

• Six model tools, registered with DSH's native tool registry:

  • html_review_start_session
  • html_review_get_session
  • html_review_claim_handoff
  • html_review_mark_handoff_sent
  • html_review_list_sessions
  • html_review_register_final

• A tool:anno system-prompt section that teaches the agent the start → review → claim → resolve workflow.

Requirements

• DeepSeek Harness >=0.1.0-rc.6 <0.2.0
• Node.js 22 or newer

Install

The package is a DSH profile bundle: dsh plugin add installs it and applies its cordis.patch.yml, which inserts the anno-native row into the profile (host) composition.

dsh plugin --profile web add @philmingdao/anno-dsh-native
# or from a source checkout:
dsh plugin --profile web add .

Then start Harness normally:

dsh web

The tools appear as html_review_* (no MCP namespace prefix). Because the row sits on the host plane, every agent on that profile shares one review server and one session store.

Source checkout

npm install
npm test
dsh plugin --profile web add "$(pwd)"

Use a temporary --dsh-home when testing without changing your normal profiles.

Use

Ask Harness to open or review an HTML file. It calls html_review_start_session with the absolute source path and opens the returned review_url for the user.

When the user clicks 提交给 Agent in the browser editor, the review server prepares the handoff and pushes it straight back into the originating agent conversation: the plugin captures the calling agent when the session is created and, on submission, queues an ordinary follow-up turn (agent.followup) carrying the full review — in-place text edits, format changes, element/area annotations, and page notes — so the agent claims the handoff immediately and resolves it into a verified standalone HTML file via html_review_register_final, without any manual polling.

The receiving turn's prompt instructs the agent to call html_review_claim_handoff first (durable receipt), then html_review_get_session to reload the full session and apply the edits and annotations against the draft HTML, then html_review_register_final. The in-process push is best-effort: if the originating agent is no longer live, the handoff is still persisted on disk and the agent can claim it through the ordinary html_review_* tools.

Architecture

DSH profile composition
  -> @philmingdao/anno-dsh-native  (cordis plugin + bundle patch)
    -> anno-core.js                (HTTP server + on-disk session/review/handoff store, node-only)
    -> index.js                    (registers html_review_* tools + tool:anno prompt section)

lib/anno-core.js is deliberately free of DSH imports and is unit-tested directly (npm test). It exposes an onHandoff hook (invoked by the HTTP generate endpoint with the full review payload) and a hasHostTarget predicate (reported as has_host_target on the session projection) so the host binding can deliver handoffs without the core depending on any host runtime.

lib/index.js is the thin Cordis binding that injects tools, systemPrompt, and agents, starts the server as a fiber-owned effect, and registers the tools using raw JSON-Schema definitions directly against the tools registry. It captures the calling agent on html_review_start_session and, through onHandoff, delivers the submission back as an agent.followup notice. It imports no @deepseek-ai/dsh-tools (or any other DSH package) — the follow-up user message is built from the same shape createUserMessage produces, using only node:crypto — so the package keeps zero external dependencies and loads from any location (including a link:-installed source checkout).

Configuration

The anno-native row accepts:

Field	Default	Meaning
host	dsh	Host kind stamped on session records.
dataDir	$ANNO_DATA_DIR or ~/.anno	Root for persisted review sessions.
assetsDir	package assets/	Directory holding editor.html / handoff.html.

Uninstall

dsh plugin --profile web remove @philmingdao/anno-dsh-native

Existing review sessions under the data directory are left in place.
