Configuration

- id: tool-rewind
  name: '@dpskh/tool-rewind'
  config:
    toolName: rewind                # model-facing tool name (default rewind)
    maxTokens: 1024                 # summarization output budget
    maxSummarizationRetries: 2      # empty-completion retries before failing
    summarizationProvider: deepseek # optional override of the routed provider
    summarizationModel: deepseek-chat
    reportLanguage: en              # en | zh (report instruction language)

Provider/model resolution order for the report call: configured overrides, then the session's last routed request/header config, then the agent's options. Missing all three fails loud.

The report call runs with thinking disabled when the route exposes an off reasoning effort — condensing an exploration is mechanical, and a reasoning model's thinking tokens otherwise compete with the report text under maxTokens (thinking can exhaust the budget before any text starts, leaving an empty completion). Empty completions retry up to maxSummarizationRetries; an exhausted budget rejects with a message carrying the finish reason and token usage, which the rejection message preserves.
