dsh-plugin-cli-session

The headless runner shipped with DeepSeek Harness is one-shot: it answers once and is discarded, with no way to continue the previous conversation. In practice, many teams end up maintaining two hand-copied profile runners (a conversational one and a claude -p-style one) whose core logic drifts into near-duplicates over time. dsh-plugin-cli-session merges them into a single plugin: one shared implementation for session resolution, the drive loop, summarisation, and exit handling, with the only differences expressed as configuration.

It gives the CLI real session lifecycle management: --resume, --list, and --session scope history by profile directory and sessionTag so two profiles in the same folder never see each other; -o json and -o stream-json emit structured envelopes (type, result, session_id, usage, etc.) on a clean stdout for pipe-friendly parsing; --workdir creates and enters a directory before the session starts. At boot the plugin validates its configuration (blank sessionTag, negative exitGraceMs, missing request) and refuses to silently create an empty session that would waste a model call.

It is built for developers who drive DeepSeek from the terminal in scripted workflows, engineers who need structured JSON responses inside CI or automation pipelines, and teams that currently maintain two profile runners and want to consolidate duplicated code under unified session management.
