dsh-stalled-turn-continue

A DeepSeek Harness (DSH) host plugin that resumes a turn which ended successfully with reasoning only — no text part and no tool call.

The problem

A model sometimes emits a reasoning block and then its end-of-turn token. DSH records that turn as turn/end with reason.kind: "completed", so the agent stops mid-thought and waits for a hand-typed "continue". dsh-client-auto-continue does not cover this case: it reacts to error, interrupted, max-tokens and host/agent-error, and by design ignores a completed turn.

Measured on 123 local session logs: 40 of 498 completed turns (8 %) ended without visible output, across four models. The rate depends on the model (from about 1 % to over 50 %).

What it does

On turn/end with reason.kind completed or no-visible-output, the plugin checks the turn's last assistant message. If that message has neither a text part nor a tool call, it waits graceMs and sends one follow-up message through the agent registry.

• It ignores error, interrupted, max-tokens, aborted and blocked, so it runs alongside dsh-client-auto-continue without double resumes.
• no-visible-output is the kind a DSH build records when it classifies this turn itself; the plugin accepts both kinds, so such a DSH upgrade keeps it working.
• A turn with visible output resets the counter; a human message or a host turn/start cancels an armed resume.

Install

dsh plugin --profile web add dsh-stalled-turn-continue

Restart DSH. The host log then shows:

[stalled-turn-continue] watching; grace=3000ms cooldown=20000ms maxConsecutive=3

Config

Override the row by id in your profile's cordis.patch.yml. Do not add a second insert with the same id — that fails the load with duplicate loader entry id.

- id: stalled-turn-continue
  config:
    graceMs: 3000
    cooldownMs: 20000
    maxConsecutive: 3

| Key | Default | Meaning | |-----|---------|---------| | enabled | true | false mounts nothing | | graceMs | 3000 | Wait after turn/end before resuming; the host may start its own turn meanwhile | | cooldownMs | 20000 | Minimum time between two resumes in one session | | maxConsecutive | 3 | Resumes in a row without visible output before the plugin waits for a human | | continueText | see index.js | Text of the follow-up message |

A patch replaces the row's whole config, so restate every key you want to keep.

Test

npm test

Remove

dsh plugin --profile web remove dsh-stalled-turn-continue
