Claude's explanatory and learning styles wrap teaching notes in ★ Insight box-drawing fences that wrap through chat text. Render those fences as titled callouts in assistant messages on web and desktop, without changing stored messages.

The remark transform keeps each message in one markdown document, preserving references, footnotes, heading anchors, code positions, and streaming. Code examples, user messages, and plans stay literal. Thread find indexes the visible insight body without hidden fences. Merged current main and preserved its streaming renderer and shared renderer cache for ordinary messages.

Evidence

before: insight fence wraps through the message

after: insight renders as a titled callout

current head: real codex response preserves callout, references, and literal code

thread find matches visible text and literal examples without phantom insight fences

Verification

Blacksmith vp run check:changed c6ef3b46ebed34fbefa1706674fe5748254cee18: format, lint, knip, 33 affected package typechecks, 43 scoped tests, and React compiler checks passed.
The added assertion in existing thread-find coverage failed before the fix and passes afterward; user messages, plans, and code remain literal.
Current merge: real Codex Luna turn through the server and web client with Playwright and /usr/bin/google-chrome; one callout, reference targets, code-copy action, reload persistence, and narrow rendering passed. Earlier takeover evidence covers find navigation and dark mode.
Two independent read-only reviews approve 9553f8c10745107f05a621b40a92cf3b3087fb11.

Native mobile still renders fences as markdown. Electron shell, Claude's own explanatory-style emission, remote relay/tunnel connections, and other operating systems were not exercised. Fences inside lists, blockquotes, or multiline inline code stay literal. Closing rules require at least three U+2500 characters at the opening indent.

Fixes #10711

Original implementation: Grok 4.7 in Cursor. Takeover: gpt-6.1-sol in the Codex harness.

Walkthrough

The client runtime adds a parser that splits assistant text into Markdown and Insight segments. The assistant timeline renders Insight segments as titled notes and regular segments as Markdown, with streaming state applied to the final segment.

Changes: Assistant Insight Rendering

Layer / File(s)	Summary
Insight parsing and public export `packages/client-runtime/src/assistantInsights.ts`, `packages/client-runtime/src/assistantInsights.test.ts`, `packages/client-runtime/package.json`	Adds and exports `splitAssistantInsights`. It recognizes Insight boundaries while preserving Markdown, code, and reference definitions. Tests cover delimiters, indentation, unfinished blocks, and line endings.
Timeline rendering `apps/web/src/components/chat/TimelineAssistantRows.tsx`	Adds segmented assistant-message rendering. Insight segments appear as titled notes, regular segments retain Markdown rendering and line breaks, and only the final segment receives streaming state.

Estimated code review effort: 3 (Moderate) | ~25 minutes

Merge Risk: External image Minimal · previous review 5c2b8

No merge-blocking issue is established; the change is ready for normal checks.

Security architecture risk: External image Minimal · up to 5c2b8

The change affects presentation without adding access, privileges, or persistent state. Insight content continues through the existing Markdown renderer with the same action context and controls.

Retained concerns No architecture-level concerns identified.

Security review details

Security Blast Radius

inferred — The inspected change affects interpretation and presentation of assistant-controlled message text in the client timeline. It does not grant that content a new service identity or a broader action context than the former whole-message renderer.

Trust Boundaries and Controls

observed — Segmentation does not introduce an alternate HTML, URL, or execution sink. Each content segment retains ChatMarkdown's URL transformation, HTML-plugin selection, and renderer-level action gating. These are preserved controls, not a claim that every pre-existing renderer behavior has been independently verified.

Resilience and Maintainability Implications

inferred — Parser progress is not shared across calls, so repeated, interrupted, or concurrent rendering does not depend on recovery of a previous parse. Partial streamed input is reparsed from the current string rather than advancing persistent transition state.

Full details: Linked Issues check

Explanation

Issue [#10711] requires Claude Explanatory Output Style Insight blocks to render as a separate UI element in apps/web. AssistantMessageBody calls splitAssistantInsights and renders insight segments as titled role="note" callouts. The parser preserves the markdown body and the focused tests cover completed, streaming, fenced-code, indentation, and line-ending cases. This implements the linked coding requirement.

Full details: Out of Scope Changes check

Explanation

The changes stay within [#10711]. The client-runtime parser, its package export, web assistant-message integration, and focused tests directly support Insight callout rendering. No unrelated product change is shown in the reviewed changes.

Full details: Description check

Explanation

The description explains the problem, change, verification, screenshots, and known limitations. It links issue #10711, but it does not show that the issue was triaged or provide a maintainer comment approving the direction and scope. The PR describes a rendering change across web and desktop, so it does not explain why the change qualifies for an approval exemption.

Resolution

Add evidence that issue #10711 was triaged and include the maintainer comment approving the direction and scope. If the change qualifies as a focused fix of an obvious bug, explain why it needs no prior issue or discussion.

Written by gpt-6.1-sol on behalf of Maria

thanks @macodev00. i kept your commits and the insight callout behavior, then merged main and simplified the implementation to use the existing markdown alert renderer.

the message now stays in one markdown document. that preserves multiline reference links, footnotes, heading anchors, and code positions while streaming. code examples stay literal. the separate client-runtime parser and export are gone; coverage moved into existing markdown and browser test files. this also addresses the original reviews about reference links, indented code, and surrounding line breaks.

passed: blacksmith vp run check:changed dd5b5401e1f240f4314af29edf431369d182f386, including format, lint, knip, affected typechecks, and 29 scoped tests.
passed: live codex responses using claude's plain and backtick-wrapped insight syntax, including a new streamed callout, surrounding links and headings, and literal code. inspected light/dark rendering and a narrower web viewport. uploaded video playback and seeking passed.
ci: all 27 checks are green.
two independent code reviews approve baf51b5b6bfee1a088c2df5809bab7939821d53c.
unverified: live claude output, since this dev instance only exposes codex; electron itself. native mobile rendering remains outside this web fix.

Verified in a real dev environment

verified unchanged head baf51b5b6bfee1a088c2df5809bab7939821d53c on this linux boat vm.

installed and ran github/main (4c9c7d0bb6) in a separate worktree first. created the project and thread through the web app and sent a real codex gpt-6.1-sol turn. main rendered the insight fences as ordinary markdown, with no callout.
stopped main, installed the exact pr head, and ran its dev server. used repo playwright with /usr/bin/google-chrome to create a fresh project/thread and send the same prompt through the composer. the assistant response renders one titled insight callout; the matching user message stays literal.
a second real codex turn verified backtick-wrapped insight fences while streaming, code and lists inside the callout, multiline reference definitions, footnote content, distinct duplicate heading anchors, and an ordinary github note outside the insight. reference links resolve before, inside, and after the callout. the code-copy button copies the exact code including its trailing newline.
verified reload persistence and inspected light, dark, and narrower web rendering. no mocks, fixtures, replay provider, or database writes.
blacksmith: vp test run packages/shared/src/markdownPipeline.test.ts apps/web/src/components/ChatMarkdown.browser.test.tsx passed all 24 existing tests after installing the worker's missing chromium dependency. current ci has 27 successful checks, none pending or failing.
inspected the captures, checked uploaded bytes, and played and sought through the uploaded 6.5-second video in t3's browser player. the comment uses an animated copy of that recording because github does not render the external mp4 inline. no code changes or pushes were needed.

before on main: real codex response leaves insight rules as markdown

after on the pr: matching real codex response renders an insight callout and preserves links and literal code

live codex response streams a backtick-wrapped insight with code, links, and a neighboring github note

narrow dark web view preserves the insight callout and literal code

Not verified

native ios/android, electron shell, macos/windows, remote relay/tunnel connections, and claude's own explanatory-style emission were not exercised on this linux vm. codex emitted the real insight syntax through the normal provider/server/web path.

footnote content and reference targets render, but mouse navigation was not verified: playwright reports a zero-height box for the footnote reference link. no claim is made about that interaction.

fix(web): exclude hidden insight fences from thread findb590bb9

Mmaria12d ago

Note

Written by gpt-6.1-sol on behalf of Maria

merged current main without rebasing and preserved the insight callout implementation. fixed the search mismatch found during review: hidden fences no longer produce phantom thread-find hits; user messages, plans, and code examples remain literal.

b590bb942b671328d854b80dee76bf18de7298d5 has 28 successful check contexts, none pending or failing, and no conflicts. github reports CLEAN. one earlier fingerprint run was superseded and cancelled; its replacement passed.

blacksmith check:changed passed format, lint, knip, 33 affected typechecks, 42 scoped tests, and react compiler checks. the search regression assertion failed before the fix and passes afterward. two independent code reviews approve this head. real codex/web verification covered callouts, reference targets, literal code, and find navigation. current evidence and surface limitations are in the pr body.

ready for maria's review and merge. no merge was performed.

Evidence

Evidence: real Chromium web client, 1280×800, light theme, fresh isolated state on each commit. Replay supplied identical synthetic explanatory and learning notes. Open the response, search body text, then search its box-drawing rule.

The scenario failed on base and passed on head. Body search returned 1/1 on both; fence search returned four matches on base and zero on head.
