Summary

  • Keep team knowledge files in a compact list with inline previews and a side-by-side conversation using the shared chat composer. Each new Ask starts a distinct knowledge task; reopening an existing task still restores its conversation.
  • Show retrieved source evidence, support validated drag-and-drop uploads, and use file-type icons across the knowledge list.
  • Start loading the PDF viewer alongside the authenticated download and pass downloaded bytes directly to PDF.js. Copy the byte buffer for each PDF.js load so an effect restart remains safe.
  • Address review feedback on spreadsheet column counting, stable source navigation callbacks, and upload documentation.
  • Keep new Knowledge draft agent, permission, model, and effort settings separate from any previously selected task.

Verification

  • corepack pnpm run ts-check — passed.
  • corepack pnpm run lint — passed.
  • corepack pnpm run format — the literal command found formatting issues only in two pre-existing, untracked reports excluded from this PR. The repository check excluding those two files passed for 1,215 files: pnpm exec oxfmt --check . '!reports/knowledge-base-execution-plan-2026-09-24.md' '!reports/knowledge-base-product-analysis-2026-09-24.md'.
  • Full test suite — pnpm exec vitest run --testTimeout 15000: 3,395 passed, 4 skipped. The default 5-second timeout was exceeded by two unrelated tests under machine load; both passed in isolation.
  • corepack pnpm run build — pnpm run build:app passed, including i18n and type checks.
  • Runtime/UI verification — not completed against a live authenticated knowledge service in this PR update.

Safety and Compatibility

  • Local BYOK and signed-in OOMOL modes were considered separately. The knowledge route is available only in signed-in OOMOL mode; the shared PDF viewer remains available to both modes.
  • No credential was exposed to the renderer, logs, fixtures, screenshots, or committed files. Knowledge requests continue through the existing HttpOnly cookie transport with the current team header.
  • Agent tools, permissions, and system prompts remain aligned. This change reuses the existing guarded knowledge retrieval context and does not alter tool or permission policy.
  • Migration, packaging, endpoint, and update implications were considered. The optional knowledgeMode session metadata is backward compatible; the PDF viewer retains URL loading for existing callers. Knowledge file preview uses the existing authenticated content endpoint. No new package or update mechanism is introduced.
  • Relevant documentation and tests were updated, including PDF effect restart coverage and knowledge workspace behavior.

Summary by CodeRabbit

  • New Features
    • Added a team Knowledge workspace for browsing, previewing, and managing files, with pagination and multi-file uploads by picker or drag-and-drop. Uploads support files up to 150 MiB and validate each file before processing.
    • Ask questions about team knowledge from the workspace, with analysis alongside the file library.
    • Chat answers can show file-grouped source evidence that opens the matching file and highlights relevant content.
    • Added previews for supported text, PDF, document, spreadsheet, and image files, with clear states for unsupported, unavailable, or oversized content.
  • Bug Fixes
    • Improved cleanup and cancellation when previews or uploads are interrupted or the active file, route, account, or team changes.
  • Documentation
    • Updated guidance for the Knowledge workflow, chat sources, uploads, and validation.

Walkthrough

The Knowledge route now combines a file workspace, uploads, file previews, and an analysis conversation. Knowledge questions create team-scoped sessions with persisted knowledge mode. Chat retrieval results expose source evidence that can open the corresponding file in Knowledge. The changes also add localized interface text and documentation for these workflows.

2069-2075: 🚀 Performance & Scalability | 🔵 Trivial | 💤 Low value

Memoize onOpenKnowledgeSource.

This inline arrow creates a new function on every AppShell render. ChatArea passes that function as the KnowledgeNavigationContext.Provider value. Each new value re-renders every KnowledgeAnswerSources and KnowledgeSources consumer in all turns, even inside the memoized ChatTurnView. The new function also defeats the React.memo on ChatArea. AppShell re-renders often while a response streams.

Proposed refactor
const activeTeamIdForKnowledge = teamWorkspace.activeWorkspace.team?.id
const activeSessionKnowledgeMode = activeSession?.knowledgeMode === true
const handleOpenKnowledgeSource = React.useCallback(
  (hit: KnowledgeHit) => {
    if (!oomolLinkActive || !activeTeamIdForKnowledge) return
    setKnowledgeSelection({ hit, teamId: activeTeamIdForKnowledge })
    if (activeSessionKnowledgeMode) setKnowledgeAnalysisActive(true)
    setRoute("knowledge")
  },
  [activeSessionKnowledgeMode, activeTeamIdForKnowledge, oomolLinkActive],
)

Declare this callback above the early route returns so that the hook order stays stable. Then pass onOpenKnowledgeSource={handleOpenKnowledgeSource}.

Correct the description of batch drop behavior.

The docs say "a drop uploads the supported files in sequence". uploadFiles in src/routes/Knowledge/index.tsx (Lines 185-190) checks every file first. If any file fails knowledgeUploadError, it sets an error and uploads nothing. A drop that mixes supported and unsupported files therefore uploads no files. Either describe the all-or-nothing validation in the docs, or change uploadFiles to skip invalid files.
