Turtle c7c1b97501 fix(agent-loop): address second-round review — disposal discard, injection validation, frozen payloads
Address the review bot's five genuinely-new findings on the current code:
- disposal now discards any still-pending inbox items before the loop
  exits, so every enqueued id gets a terminal lifecycle event.
- injection (next-step/no-wakeup) validates its payload up front, before
  opening the idle one-shot turn, honoring 'invalid input throws before
  any append'; and rejects attached contexts (which belong only to inbox
  messages) rather than silently dropping them.
- agentMessage() freezes the agent/inbox/* payload so a listener cannot
  mutate the shared correlation object mid-dispatch.
- refresh the package READMEs (compact, goal, guard, hook-protocol,
  plan-mode, time-context, workspace-context) that still referenced the
  removed context/message event, with the source-based user/message
  distinction.

The up-front injection validation makes two finally branches unreachable
(v8-ignored as the turn-enclosure backstop). Adds regression tests for
disposal discard, context rejection, up-front validation, and the frozen
payload; per-file coverage stays 100%.

DeepSeek Harness

English | 中文

DeepSeek Harness (dsh) is an open-source coding agent built on the DeepSeek Harness SDK.

It uses an architecture where everything is a plugin.

Install

Install dsh with one command:

curl -fsSL https://raw.githubusercontent.com/deepseek-harness/deepseek-harness/master/scripts/install.sh | sh

The installer requires git and Node ^22.19 || >=24, offers to install pnpm when it is missing, and prompts for a DeepSeek API key.

The installer clones DeepSeek Harness to ~/.dsh/source, links dsh into ~/.local/bin, and launches it. Re-running the command updates the checkout. See scripts/install.sh for alternate install locations and other options.

Use DeepSeek Harness

Web UI

For the recommended local interface, build the frontend after installation and after each update, then start the Web UI:

pnpm --dir ~/.dsh/source run build && pnpm --dir ~/.dsh/source run build:web
dsh web

The Web UI is served at http://127.0.0.1:3080 by default.

TUI

Start the full-screen terminal interface:

dsh

Headless

Run one task, print the final answer, and exit:

dsh -p "summarize this workspace"

Why DeepSeek Harness

Built-in capabilities cover file reading, editing, and search; shell execution; reusable skills; task tracking; subagents and workflows; persistent sessions; and context compaction. The TUI also includes Plan Mode.

  • Everything is a plugin. Models, tools, policies, storage, context management, and interfaces are composable Cordis plugins, so deployments can extend or replace behavior without forking the agent loop. See the architecture for the underlying design.
  • Code Mode (opt-in). It exposes a run_code tool and a generated TypeScript SDK; only program output re-enters model context. See Code Mode.
  • Self-referential Cordis tools are opt-in. They let the agent inspect its live runtime and mount or unmount plugins while it runs. See the Cordis tools.
