English | 中文

Optional ctx.sessionTitle provider that summarizes every eligible human message through ctx.llm. It registers the all-prompts cadence and starts a new revision after each new human prompt, using seeded history as well as child-session prompts. A newer revision aborts and supersedes older work; even a provider that ignores cancellation cannot commit stale output.

The plugin uses the complete required shared LLM configuration. Omit both provider and model to inherit the exact route from each current logged main request, or set both to route title generation independently. If the final framed aggregate prompt exceeds maxInputBytes, the request fails instead of truncating history; automatic use warns and keeps the prior title.

Model Experience

All-messages title request

What the model sees

The title model receives the shared title instruction and a JSON array of all eligible human messages through the current revision, in log order with exact seqs. Seeded history is included.

Token effect

One auxiliary request may follow every new eligible prompt, bounded per request by maxInputBytes and maxOutputTokens; explicit refreshes may add calls. The main agent request gains zero tokens.

KV Cache effect

No main-request invalidation. Auxiliary input grows or changes after each prompt, so provider-specific cache reuse ends at the first changed JSON token.

Known Limitations and Deferred Work

• Input overflow retains the prior title; this provider has no summarization-of-summaries or retention policy for very long sessions.
• It treats all eligible human messages equally and offers no weighting, filtering, or manual-title precedence.
