# @dsh-external/dsh-compaction-current-model

DSH host bundle that fixes a manual-compaction model-selection bug for
DeepSeek Harness `0.1.0-rc.7`:

- Before the fix, `/compact`（手动压缩）summarization could use the session's
  last routed model even after the frontend model picker changed.
- This plugin tracks the durable manual-compaction span
  (`compaction/start` with `turn: null`) and rewrites the summarization
  `llm/stream` to `agentDefaultModel.currentSelection()` — the model the
  frontend currently shows.

Automatic compaction, ordinary chat requests, and frozen LLM requests are
never rewritten.

## Install

```powershell
dsh plugin --profile web add github:JK-LIL/dsh-compaction-current-model
```

or from a local tarball:

```powershell
dsh plugin --profile web add ./dsh-compaction-current-model-0.1.0.tgz
```

then restart the web profile and run `/compact` after switching models.

## Compatibility

- Built against DeepSeek Harness `0.1.0-rc.7` (source mode or installed build).
- Runtime-import-free: the plugin only calls the Cordis context and standard
  session/LLM events, so it has no package dependencies of its own.
- If a future DSH version changes the `compaction/start` owner marker,
  `llm/stream` request shape, or `agentDefaultModel`, review this plugin before
  upgrading.

## Uninstall

```powershell
dsh plugin --profile web remove @dsh-external/dsh-compaction-current-model
```

## Verification

From the plugin package:

```powershell
npm run typecheck
npm run build
```

Runtime acceptance: start DSH web, switch the model picker to a model different
from the last routed request, then run `/compact` and confirm the recorded
`compaction/summary` provider/model matches the frontend selection.
