調査の方向性

Start with core/session/title.go, especially titleRules, firstLine, quickRank, and the comments around TestScreenedRules_CoversEveryHighRankingTag. Compare core/observe/claude/harvest.go's stripWrapperTag and pasted_content allowlist, then add coverage for the four cases listed in the issue. Done means pasted tags no longer become titles, other wrapper output and prose mentioning the tag remain intact, and the screened title ranking stays sound.

bug

What happens

A Claude Code session whose opening message is a paste gets the session title <pasted_content id="8f8e">: the paste's opening tag, not anything the user wrote. Titles are first-wins, so it keeps that title for the rest of the session.

Seen on a live laptop proxy on 2026-10-21. GET /v1/sessions served:

{"id": "7aa5f31e-…", "title": "<pasted_content id=\"8f8e\">", "agent": "claude-code", "eventCount": 492}

agentop shows the served title whenever its transcript harvest can't name a session. It couldn't name this one: the session ran under a second Claude Code config directory that the harvest doesn't read (a separate gap). So the tag is what the user saw in the TITLE column.

Why

The title came from Claude Code's own title-generation request rather than from a conversation turn. That request wraps the user's opening message in <session>…</session> and asks the model to write a title:

<session>
<pasted_content id="8f8e">
The list screener is showing
ONS_057: 1 run(s) | UNPLACED 1 -- nothing outstanding
MuPDF error: library error: FT_New_Memory_Face(*Tahoma-Bold-12379): unknown file format
</pasted_content id="8f8e">
</session>

Write the title in the predominant language of the session — …

core/session/title.go has a <session> rule (titleRules, the takeFirstLine row) that takes the first non-blank line inside the wrapper (firstLine). Here that line is <pasted_content id="8f8e">. No rule in core/session recognises <pasted_content>, so the tag is returned as the title. sanitizeTitle only folds whitespace and control runes, and foldsBlank passes it because it isn't blank.

A bare pasted opening message, with no <session> wrapper, probably goes wrong the same way through the generic prose rule. It opens with the tag, nothing anchors on it, and its first line is the tag. I haven't confirmed that path.

The harvester already handles this

core/observe/claude/harvest.go solved the same problem for transcript titles, in #1101. stripWrapperTag unwraps a leading content-bearing wrapper to its body. contentBearingWrappers is an allowlist whose only entry is pasted_content, and the result is re-tested so that an empty body, a nested wrapper or leftover markup still can't become a title. Its comments explain why it's an allowlist: unwrapping anything tag-shaped once put <bash-stdout> output in a title.

The proxy keeps its own copy of the title logic and doesn't import the harvester. A comment in title.go says that is deliberate. So the fix belongs in core/session, applying the same rule there rather than calling the harvester.

Expected

For the event above, The list screener is showing. That is the first line of what the user pasted, which is also what the harvester would choose. Claude Code's own title for the session was "MuPDF FT_New_Memory_Face error", but the proxy takes a line from the user's text rather than summarising, so matching that isn't the goal.

Suggested fix

  • In core/session/title.go, unwrap a leading <pasted_content …> (with or without attributes) before a line is chosen, both inside a <session> / <conversation> / <bash-input> body (before firstLine) and at the start of a plain user message.
  • Allowlist only pasted_content, for the reasons the harvester gives. A wrapper that holds harness output must still fall through to the next candidate.
  • Re-test the result so leftover markup names nothing (rank none) instead of becoming the title. The empty-body and nested-wrapper cases the harvester covers apply here too.
  • The close tag carries the id as well (</pasted_content id="8f8e">), so a match that expects a bare </pasted_content> would miss it.
  • Keep quickRank's guess sound: the unwrapped result must not rank above what the screen guessed. See the comments on quickRank and TestScreenedRules_CoversEveryHighRankingTag.
  • Tests:
    • the <session>-wrapped paste above
    • a bare pasted opening message
    • a paste with an empty body
    • prose that only mentions <pasted_content> partway through, which must keep its own words

Not this issue

agentop's harvest reads one Claude Code config directory (CLAUDE_CONFIG_DIR, else ~/.claude), so sessions run under another profile such as ~/.claude-pro are never named from their transcripts, even when Claude Code wrote a good ai-title for them. That is why the served title was visible at all here, and it needs its own fix.
