The CLI cancels pending regeneration before session invalidation, reload, or shutdown. Running `/name` again cancels the previous request; late results cannot append metadata to the outgoing session. Manual names, including explicitly cleared names, take precedence over automatic naming. Metadata changes, session replacement, reload, and shutdown cancel pending automatic generation; stale responses cannot rename a replacement session. Failure retains the prompt fragment.

On the first nonempty prompt, it persists a sanitized prompt fragment via `pi.setSessionName()`, then a separate, nonblocking request to the active model generates a short task title in the user's language. Titles are limited to 30 terminal columns (15 CJK characters, about 30 Latin characters), keep only the first line, and drop quotes and trailing punctuation. The request uses the provider-neutral simple API without a reasoning level, the same thinking-off mode as selecting `off`; a model that cannot disable thinking applies its server default. It contains at most 2,000 prompt characters, no history or tools, a 256-token output limit, and a 15-second timeout. It is an additional provider request and may incur provider charges; its usage is not included in transcript totals. - -`/name` without an argument regenerates the title from the conversation on the current branch: the original request (at most 2,000 characters) plus the most recent user and assistant text, bounded to 8,000 characters in total, with the same request limits. The result is persisted as a normal `session_info` entry. If the name or session changes while the request runs, the result is discarded; failure keeps the current name. The CLI cancels pending regeneration before session invalidation, reload, or shutdown. Running `/name` again cancels the previous request; late results cannot append metadata to the outgoing session. - -Manual names, including explicitly cleared names, take precedence over automatic naming. Metadata changes, session replacement, reload, and shutdown cancel pending automatic generation; stale responses cannot rename a replacement session. Failure retains the prompt fragment. Named sessions are not renamed automatically on follow-ups or resume. Noninteractive modes do not generate titles. - The existing `session_info_changed` UI path updates the terminal title using OSC 0, with control characters removed from dynamic title text. Named sessions display only their name; unnamed sessions retain the product and directory fallback. This protocol is used by Apple Terminal, iTerm2, Ghostty, Otty, and other compatible terminals; visibility depends on the terminal's tab/window title settings. Per-tab busy state is a separate OSC 9;4 indicator controlled by `terminal.showTerminalProgress` (see [settings](settings.md)); no notification, bell, or completion status is added. ## Tree Structure diff --git a/packages/coding-agent/docs/sessions.md b/packages/coding-agent/docs/sessions.md index a6a96d4e..c4d30391 100644 --- a/packages/coding-agent/docs/sessions.md +++ b/packages/coding-agent/docs/sessions.md @@ -25,7 +25,7 @@ For the JSONL file format and SessionManager API, see [Session Format](session-f |---------|-------------| | `/resume` | Browse and select previous sessions | | `/new` | Start a new session | -| `/name ` | Set the current session display name; `/name` alone regenerates it | +| `/name ` | Set the current session display name | | `/session` | Show session info | | `/tree` | Navigate the current session tree | | `/fork` | Create a new session from a previous user message | @@ -57,8 +57,6 @@ Use `/name ` to set a human-readable session name: /name Refactor auth module ``` -An unnamed interactive session gets a short title from its first prompt.
