Claude /context output can fill a thread with long tables. Show the latest recognized report above the composer, in the same banner area as usage limits, on web and desktop. Mobile gets the same docked report.

The card shows token usage, a stacked bar, and expandable tool, skill, agent, and memory sections. Each report remains available through a collapsed timeline row after dismissal or when a newer report arrives. Unknown report formats keep the existing Markdown view.

Verified: 153 focused parser, card, Markdown, timeline, and mobile-label tests; shared/web/mobile typechecks; focused lint; CI. Live Browser checks confirmed placement above the composer and access to the full report from the timeline. The fixture follows real Claude Code 2.1.261 output.

Native mobile UI was not exercised on a device. Future Claude report formats may use the Markdown fallback.

Addresses #12074.

Implemented with Claude Fable 5.1 in Claude Code via T3 Code. Reviewed and integrated with GPT-6-Astra in the native Codex harness.

🟡 Minor · Include the token and row count in the section's accessible name. · ComposerClaudeContext.tsx:21-26

apps/mobile/src/features/threads/ComposerClaudeContext.tsx:21-26
🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Include the token and row count in the section's accessible name.

accessibilityLabel={section.title} replaces the row's entire accessible name. React Native does not fall back to the row's visible child text when accessibilityLabel is set. A screen reader announces only the section title. It does not announce the token count or row count that a sighted user sees in the same row.

Include the token/row-count summary in the label so screen reader users get the same information as sighted users.

🛡️ Proposed fix to restore the visible summary in the accessible name
       <Pressable
         accessibilityRole="button"
         accessibilityState={{ expanded: open }}
-        accessibilityLabel={section.title}
+        accessibilityLabel={`${section.title}${
+          section.totalTokens !== null ? `, ${formatClaudeContextTokens(section.totalTokens)}` : ""
+        }, ${section.rows.length} ${section.rows.length === 1 ? "item" : "items"}`}
         onPress={() => setOpen((value) => !value)}
         className="min-h-11 flex-row items-center gap-2"
       >

Based on learnings: reviewers should flag interactive elements that lack ARIA/accessibility attributes conveying information available to sighted users.

The arrow points to the original /context message in the timeline. It stays as a collapsed row so the report remains available after the composer card is dismissed or a newer report replaces it. The composer card shows the latest report.

I cannot provide a native mobile screenshot from this host: the T3 Device panel has no available simulator or emulator (iOS needs macOS; Android SDK is absent). The mobile component test, typecheck, and focused lint pass. I also pushed 814dac8 to make the mobile section labels announce their token and item counts.

Claude Code answers `/context` with several stacked markdown tables, often
hundreds of rows, which pushes the conversation out of view on desktop and
means dozens of screens on mobile. Parse that report on the client and show
a collapsible card instead: model, used/max tokens, a stacked usage bar, the
category breakdown, and each long table folded to one row with its total
and count.

The parser is strict about the shape it accepts and returns null on any
unconsumed or malformed content, so unknown CLI output keeps rendering as
plain markdown. Web wires it through a `contextReportCard` flag on
ChatMarkdown so only assistant timeline messages opt in; mobile renders the
same shared report in a native card.

Model: Claude Fable 5.1. Harness: Claude Code via T3 Code.
The user asked for the /context card to sit where the usage limits result
does, above the composer, rather than inside the timeline. The newest
settled `/context` report in the thread now feeds a dismissable composer
banner on web and a docked card on mobile, both reusing the shared parser.
The timeline message collapses to a one-line pointer so the report is not
shown twice. Unrecognised report shapes still render as markdown.

Model: Claude Fable 5.1. Harness: Claude Code via T3 Code.
The timeline row for a recognised report pointed at the composer even for
older reports and after the composer card was dismissed, which hid that
data. Each report message is now a collapsed disclosure row, matching the
thinking rows, that expands to the full card inline. The composer card
still shows the latest report. Leading whitespace before the heading is
accepted again.

Model: Claude Fable 5.1. Harness: Claude Code via T3 Code.
The composer card kept showing the last /context report for the rest of the
thread, so after later turns it displayed outdated token usage above the
composer. The card now shows only a report that answers the latest user
message; older reports remain in the timeline.

Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
The same /context report rendered twice: as a disclosure in the timeline and
as a card above the composer. Keep the timeline row, which persists across
reloads and devices and lets earlier reports be compared, and drop the
composer card with its per-session dismissal state.

main now rejects arbitrary Tailwind values, so `stroke-[1.8]` failed lint.
Match the other timeline disclosure icons, which use `stroke-2`.

🟡 Medium chat/MessagesTimeline.tsx:2378

Context-report messages no longer resolve saved assistant citations: opening a citation falls back to the generic changed-quote view instead of highlighting the quoted report text. The contextReport branch replaces ChatMarkdown inside AssistantCitationSource, and ClaudeContextDisclosure omits the collapsed table rows from the citation DOM; preserve the report’s source text in the citation DOM while using the disclosure for display.

This comment is posted by Julius' dot

Closing under the verification rule. The web screenshots and focused parser/component checks are useful, but the new native context-report UI is still unverified. Julius requested mobile evidence, and the reply and current description confirm none was captured. Please add native before/after screenshots and a short recording showing report expansion and scrolling through its long sections, then request reconsideration.

Apply the final net changes from PR pingdotgg#13062 onto current main. Keep the original report parser, cards, Markdown fallback, and timeline-only placement. Adapt disclosure expansion to the V2 work-row state and retain the original native report row layout.

Source: 57d87f6

Verified 160 focused tests, shared/web/mobile typechecks, and focused lint. Native mobile evidence is pending root capture.

Restore the original composer integration from PR pingdotgg#13062 before its timeline-only change. Web and desktop read the V2 conversation projection; mobile reuses the original selected-feed report lookup and docked card.

Keep per-thread dismissal, replacement by newer reports, hiding after the next user message, collapsed timeline access, and unknown-format Markdown fallback.

Verified 35 shared report tests, 2 composer banner tests, shared/web/mobile typechecks, and focused lint. Native mobile capture remains with root.
