@deep-tui/plugin-compact

Adds /compact (alias /summarize) to Deep TUI.

/compact asks the configured model for a checkpoint and appends that checkpoint to the active conversation. The summarizer replays the selected conversation prefix with the same system prompt and tool schemas, then appends the compaction instruction as the final user message. This keeps DeepSeek's warm prefix eligible for reuse.

The session log remains append-only: original records are retained for audit and recovery, while the checkpoint shadows them on the model-facing surface. Recent records stay verbatim. Oversized tool results are first replaced on the surface by bounded head/omission/tail records; their originals also remain in the log.

Use /compact [focus] to tell the summarizer what the next conversation should care about:

/compact
/compact focus on the parser edge cases we still need to fix

The generated summary is stored in <compacted-summary> framing at the position of the replaced prefix. /compact stays in the current conversation.

Configure the summarizer model separately from the main agent:

{
  "use": "@deep-tui/plugin-compact",
  "config": {
    "provider": "deepseek",
    "model": "pro",
    "maxTranscriptChars": 40000,
    "maxRecordChars": 8000,
    "maxSummaryChars": 12000,
    "retainRecentRecords": 8
  }
}

provider and model default to the latest persisted request route, then the active conversation route. Keeping that route unchanged is required for cache reuse. maxTranscriptChars selects a whole-record prefix rather than truncating its contents; maxRecordChars controls model-free tool-result pruning.
