Two stages, both off the critical path: 1. **Instant** — a deterministic title derived from the first user message, written before the model is even called. Costs nothing, cannot fail, and means a session is named the moment it starts instead of after the first turn finishes (which measured p50 151s / p90 1212s on real sessions). 2. **Upgrade** — one small-model call that replaces the derived title with a proper one. Runs on a cheap/fast tier, with thinking disabled and the response constrained to a JSON object, so there is no reasoning preamble to strip and nothing to parse out of prose. Provenance (``derived`` < ``llm`` < ``user``) is enforced by the storage layer, so stage 2 can only ever replace stage 1, and neither can replace a name the user typed. That ordering is the industry-standard one — Codex CLI encodes the same ``custom > ai > fallback`` precedence in its session importer. N)AnyCallableOptional)call_llm)LEGACY_SUMMARY_PREFIX)flatten_message_texti0 aYou name chat sessions. Given the user's opening message, write a title that lets them find this conversation again in a list. Rules: - 3 to 7 words, sentence case (capitalize only the first word and proper nouns). - Name what the user wants DONE, not that they asked a question. - Keep technical terms, filenames, numbers, and error codes exact. - Drop filler words: the, this, my, a, an. - No trailing punctuation, no quotes, no tool names, no 'Title:' prefix. - Never answer the message. Name it. - Always produce something, even for a bare greeting. __LANGUAGE_RULE__ Good: {"title": "Fix login button on mobile"} Good: {"title": "Postgres connection pool exhaustion"} Good: {"title": "Friendly greeting"} Too vague: {"title": "Code changes"} Too long: {"title": "Investigate and fix the issue where the login button does not respond on mobile devices"} Reply with JSON only: {"title": "..."}z=- Write the title in the same language as the user's message.z - Write the title in {language}. json_schema session_titleTobjecttitletypestringF)r propertiesrequiredadditionalProperties)namestrictschema)rr ) )zz)zz)zz)zz)zz)zz)zz)zz)zz)zzz[CONTEXT COMPACTIONz[Runtime note:z [System note:z[SYSTEM]z7[System: The active model for this chat has changed to returnc ddlm}t|pidpididdS#t $rYdSwxYw)zDReturn configured title language, or empty string to match the user.rload_config_readonly auxiliarytitle_generationlanguage)hermes_cli.configrstrgetstrip Exceptionrs 9/home/agent/.hermes/hermes-agent/agent/title_generator.py_title_languager%s ::::::""$$* / / < < B S#R ( ( SR    %''   rrsA-A00 A>=A>c" ddlm}ddlm}|}|dpidpi}||ddS#t $r t d d YdSwxYw) z=Return whether automatic session title generation is enabled.rr)is_truthy_valuerrenabledT)defaultz'Failed to read title_generation.enabledexc_info)rrutilsr'r!r#loggerdebug)rr'config title_configs r$_auto_title_enabledr1s  ;:::::))))))%%'' ;//52::;MNNTRT |// ::DIIII  > NNNttsA!A$$&B Btextc|sdS|}tttdzD]}|}tD]\}}||s-||}|dkr*|t|d}nk|t||}||t|zd}|p|}||krn|}|S)a]Remove leading machine-authored control wrappers, including nested ones.

No model, never fails. This is what the user sees within milliseconds of sending their first message. It is intentionally dumb — first meaningful line, trimmed to a word boundary — because its job is to beat the model to the screen, not to beat it on quality. The model's title replaces it moments later.

The write goes through ``set_auto_title`` (precedence check + write in one transaction) so a manual ``/title`` set while generation was in flight is never overwritten. ``ValueError`` means the name is taken by an unrelated session (the unique-title index); rather than leave the session untitled (#50537), append a ``#N`` suffix via ``get_next_title_in_lineage``. ``dedupe=False`` re-raises that collision instead. The derived title is the one write on the turn's critical path, and it is also the one that collides constantly — it is a slice of the user's own words, and people open sessions with "hi" and "help me debug this". Scanning the lineage for the next free "hi #N" is a widening scan, run inline, for a name the model replaces a second later. The background stage picks the collision back up, so nothing is lost by declining it here.

Hermes persists a lot of machinery under ``role="user"`` — compaction handoffs, model-switch markers, background-process notices — because strict OpenAI-compatible providers reject a system message that isn't first. Counting those as turns is what made a session that merely *opened* with one look like it was already past the point where titling applies. A multimodal turn is judged on its text, so "here's a screenshot, fix the login" counts as the real question it is. rrFrg)rMrvr!rRr r)rrgs r$_is_real_user_turnrss gt $ $ F(;(;v(E(Eukk)$$G $gs++N1Eg1N1N  rEct|dd}t|sdS t||pd S#t$r!t d|dYdSwxYw)uWhether the session still carries no title of any provenance. Titling normally reads the opening message and nothing else, but an opener isn't always titleable: an image with no caption, a compaction handoff, a bare slash command. Those sessions stayed nameless for life — the same guard that stops us re-titling on every turn also stopped us ever trying again. This reopens the question on later turns, and only while the answer is still missing, so a named session asks nothing and pays nothing. Answers False when it can't tell: an unreadable title is not a reason to start spending a model call per turn. rNFrzUntitled check failed for %sTr*)rcallabler r"r#r-r.)rrgetters r$_session_is_untitledrsZ!4d ; ;F F  uvvj))/R00668888  3Z$ OOOuus,A'A<;A<conversation_historyc |r|r|sdStd|pgD}|dkrt||sdSt|sdStstddSt ||||tjt|||f||||ddd} | dS) aTitle a session from its opening message: instant, then upgraded. Call this at the START of a turn, before the model is invoked. The derived title is written inline (sub-millisecond) and the model upgrade is forked onto a daemon thread, so nothing here is on the critical path. Only acts on the session's opening exchange, and only when the message carries real user intent (machine-authored compaction handoffs are skipped).
