Problem

Images returned by MCP tools and OpenCode tools, including the HTML preview screenshot, did not appear in expanded tool details. JSON tool arguments and results also lacked syntax highlighting.

Change

Preserve image content alongside structured MCP results and extract inline images from OpenCode tool attachments. Render those images in web tool details. Add JSON highlighting for valid JSON tool arguments and results across web, desktop, and mobile, and HTML highlighting for preview input.

The CI Test job also escapes non-ASCII console output to work around repeated runner crashes while validating this PR. The runner failed with EncoderFallbackException on multiple workers and published no test log. Escaping the output allowed CI to publish its test failures, which exposed two Pi assertions affected by the new formatting behavior. The same tests run, and pipefail preserves their exit status.

Scope and approval

Requested directly by a maintainer in T3 Code, including provider compatibility, syntax highlighting, verification, and squash merge after CI and review. This fixes missing output from existing tool calls and formatting in their details. The CI logging workaround is included because repeated runner failures blocked validation of this change.

Verification

Focused tests cover MCP and OpenCode image outputs and JSON detection, including multiple JSON documents and invalid JSON. Pi coverage also verifies that native file text remains readable when its result includes metadata, while screenshots display structured JSON beside their images. The iOS client check confirmed that the HTML preview details show its screenshot and formatted JSON. All 729 affected tests and changed-file checks passed.

vp run check:changed passed formatting, lint, Knip, GraphQL validation, affected-package typechecks, 10 focused test files with 729 passing tests, and the React compiler checks. Earlier counts of 619 and 623 came before subsequent fixes and the main-branch update. Local probes of the CI log pipeline verified exit codes 0 and 7, stderr forwarding, and emoji escaping.

Approvability

Verdict: Approved at 81a30ee

Macroscope's review found this PR approvable — Tool images from MCP and OpenCode are preserved for display, with improved structured-output highlighting. Existing image-type, count, and serving-size safeguards limit exposure; the CI change only sanitizes test output.

Walkthrough

MCP adapters now preserve image content in tool results. OpenCode passes file attachments through live and backfilled tool output. Mobile and web inspectors render output images separately and highlight recognized JSON and HTML, alongside TypeScript highlighting for JavaScript REPL code.

Changes: Tool output preservation and inspection

Layer / File(s)	Summary
MCP result normalization `packages/shared/src/toolOutput.ts`, `packages/shared/src/toolOutput.test.ts`, `apps/server/src/orchestration-v2/Adapters/ClaudeAdapterV2.ts`, `apps/server/src/orchestration-v2/Adapters/ClaudeAdapterV2.test.ts`, `apps/server/src/orchestration-v2/Adapters/CodexAdapterV2.ts`, `packages/provider-acp/src/server/adapter.ts`, `packages/provider-cursor/src/server/adapter.ts`, `packages/provider-cursor/src/server/adapter.test.ts`, `apps/server/src/orchestration-v2/Adapters/OpenCode2AdapterV2.test.ts`	A shared helper selects MCP result output and retains content with images when structured content is present. Claude, Codex, and ACP use the helper. Cursor projects successful MCP text and image parts into completed tool output. Tests cover image output and dynamic-tool lifecycle updates.
OpenCode file attachments in tool output `packages/provider-opencode/src/server/toolItems.ts`, `packages/provider-opencode/src/server/toolItems.test.ts`, `packages/provider-opencode/src/server/adapter.ts`, `packages/provider-opencode/src/server/adapter.test.ts`, `packages/provider-opencode/src/server/v2/adapter.ts`	OpenCode converts supported image data-URI attachments into tool output. Live and backfilled completed tools pass file parts through the output path. Tests cover accepted and rejected image inputs.
Tool text detection and highlighting `packages/client-runtime/src/work-log/itemDetail.ts`, `packages/client-runtime/src/work-log/itemDetail.test.ts`, `apps/web/src/components/chat/V2ItemInspector.tsx`, `apps/mobile/src/features/threads/thread-work-log.tsx`	A shared helper recognizes JSON documents. The inspectors use it to highlight recognized JSON, render HTML arguments with HTML highlighting, and keep JavaScript REPL code highlighted as TypeScript. Tool output images render separately from text.

Full details: Title check

Explanation

The title "fix(tools): show images from MCP and OpenCode outputs" matches the main change. The PR preserves image content in MCP results, extracts inline images from OpenCode tool attachments, and renders those images in web tool details. It follows the conventional commit format. The title does not mention the JSON and HTML syntax highlighting work, which is a secondary part of the changeset. That omission is acceptable because the title does not need to cover every detail.

Full details: Description check

Explanation

The description includes all required sections. It clearly explains the problem, the changes across components, the scope and maintainer approval, and focused verification results. It also reports limitations and CI logging details. The description does not include a direct approval link or embedded UI screenshots, but these are minor omissions and the overall description is complete.

Render tool output images after the tool call input.

When a tool returns images, ToolCallBody shows those images before the command and arguments. Move ToolOutputImages below the argument rendering so the input appears before its result. (raw.githubusercontent.com)

The maintainer explicitly requested the preview image before the HTML source. This ordering is intentional and matches mobile tool details. Keeping the image first.

@Yash-Singh1 Understood. The image-first ordering is intentional. My comment treated an input-first preference as a correctness issue. I withdraw the recommendation; no change is needed.

Bound the persisted marker count without changing image indexes.

The persistence and wire paths do not retain the unbounded encoded payload. However, persistence preserves a marker for every image beyond the first eight, so many attachments can still create an unnecessarily large stored output.

Any count bound must preserve the first MAX_TOOL_OUTPUT_IMAGES indexed markers, including oversized markers. Do not remove an oversized marker before shared image selection, or AssetAccess can resolve later images at the wrong index.

✅ Confirmed as addressed by @Yash-Singh1

YYash-Singh110d ago

Note

Generated by GPT 6.1 Sol

Confirmed and fixed in the OpenCode converter: stop after the first MAX_TOOL_OUTPUT_IMAGES supported raster images. Oversized images still occupy their original indexed position and remain subject to the existing persistence and asset-serving byte limits. The regression test first failed with 10 markers instead of 8 and now passes, including an oversized first image followed by a normal image.

CcoderabbitaiBot10d ago

@Yash-Singh1 Thanks for confirming the fix. The reported cap addresses the marker-count concern while preserving oversized-image indexes. The regression test covers both the count limit and index preservation.

5	Learning: In packages/shared/src/toolOutput.ts, toolOutputImageBlocks and toolOutputImages preserve image positions and the MAX_TOOL_OUTPUT_IMAGES cap, including oversized image blocks. Do not filter oversized blocks from this selection, because clients and AssetAccess use these positions as asset indexes. In apps/server/src/orchestration-v2/toolOutputImageBytes.ts, the stripper determines whether selected blocks are served by checking MAX_TOOL_OUTPUT_IMAGE_BASE64_LENGTH, shared with apps/server/src/assets/AssetAccess.ts.

Keep structured MCP details visible when preserving images.
codexMcpToolOutput now preserves both fields so images remain available, but turnItemOutputText formats that envelope from content only. This changes the base behavior and can hide structured details such as temp: 21 in both inspectors. Keep content for image extraction, but add a display path for the normalized envelope that formats structuredContent instead of discarding it.

Preserve external MCP tools as dynamic tools.
For an external MCP name such as mcp__acme__edit_document, resolveT3McpToolId returns null because it recognizes only T3 server aliases. The edit check then selects file_change, which drops result.files. The web work-log and asset consumers only read images from dynamic_tool items, so the inline image is absent from the expanded tool details.
Carry the MCP classification into openCodeToolTurnItem, or recognize the generic OpenCode MCP namespace before the edit check. Keep native OpenCode edit tools on the file_change branch.

Verified both findings in the latest CodeRabbit review and fixed them within the existing tool-output scope.

Structured MCP metadata now remains the displayed result when image content accompanies it. Regression cases cover image-only content, a prose summary, and duplicate JSON content while preserving the image resource.
Explicit mcp__… names now stay dynamic tools before OpenCode's native edit-name heuristic. The OpenCode 2 replay covers mcp__acme__edit_document with an inline image. Native edit classification is unchanged.

Both regressions failed before the fixes and now pass. All 623 affected tests pass.

Keep markers for images beyond the display limit.

When a result has structured content and more than eight images, this return suppresses the [image] markers for the remaining images. The image accessor exposes only the first eight, so users cannot tell that images are missing. Preserve overflow markers alongside the structured text. (raw.githubusercontent.com)

Confirmed with a failing regression. The structured-result path now reuses the existing image-block marker formatter and appends the unserved image markers to the structured text. The existing overflow test now covers an envelope with structured metadata, including the unchanged eight-image resource limit.

CcoderabbitaiBot10d ago

@Yash-Singh1 Thanks for confirming the fix and regression coverage. Preserving the overflow [image] markers alongside structured text addresses this finding while keeping the eight-image resource limit unchanged.

Do not filter oversized blocks from this selection, because clients and AssetAccess use these positions as asset indexes. In apps/server/src/orchestration-v2/toolOutputImageBytes.ts, the stripper determines whether selected blocks are served by checking MAX_TOOL_OUTPUT_IMAGE_BASE64_LENGTH, shared with apps/server/src/assets/AssetAccess.ts.

Serialize structured content as data.

mcpToolResultOutput keeps structuredContent as structured data beside image-bearing content. The inspector must not pass that value through the content-block parser. For {type: "text", text: "Sunny", temp: 21}, the current path displays only "Sunny" and hides temp.

Use a JSON-only formatting path for structuredContent, while preserving the existing null and empty-value fallback behavior.

Confirmed with a failing regression. Structured metadata now uses JSON serialization directly, so fields such as type, text, and content remain data and cannot be mistaken for MCP content blocks. Null and empty metadata still fall back to the textual content. Extended the existing cases to cover both block-shaped metadata examples.

CcoderabbitaiBot10d ago

@Yash-Singh1 Thanks for the update. The reported fix addresses this finding: JSON serialization preserves block-shaped metadata as data, while null and empty metadata retain the textual fallback. The regression cases cover the reported field-loss issue.

Holding the merge because the Test job has crashed in GitHub Runner on three attempts of the current commit, including two reruns on different Blacksmith workers. The repeated annotation is System.Text.EncoderFallbackException: Unable to translate Unicode character \\uD83D at index 500 to specified code page, with stack frames in GitHub.Runner.Common.HostTraceListener and GitHub.Runner.Worker.Program. The job reaches the Test step but never records its completion; this does not establish that the suite passed or that an application assertion failed.

Latest failed attempt: https://github.com/pingdotgg/t3code/actions/runs/41729261310/job/126247395354

All 624 affected local tests and changed-file checks pass. Macroscope approved the current commit, CodeRabbit reports minimal risk with no actionable merge blocker, and all four review threads are resolved. The product diff remains within the requested scope. No CI bypass or unrelated runner/workflow change was made. The runner failure needs to be resolved and Test/Check must pass before squash-merging.
