Documents the agent writes open in the workspace panel instead of another
application, and local images the agent mentions show up in the conversation.
Workspace preview
- PDF (pdf.js with its own layout and text layer), Word (docx-preview inside a
scripts-disabled sandboxed iframe) and Excel (SheetJS; .xlsx, .xlsm, .xls) open
in the side panel with zoom and fit, per-file scroll/zoom/sheet memory, and a
refresh when the agent rewrites the file. The engines load lazily.
- Bytes come from a new GET /api/sessions/:id/workspace/raw route, with an
extension allowlist, size caps, the workspace boundary and canonical-path
checks. The file endpoint returns metadata and a version for documents. The
client fetches with the bearer credential, so it works in Electron, LAN H5 and
remote access alike.
- Chat links, output cards and the change card open pdf/docx/xlsx in the
workspace; documents outside the workdir still go to the system application.
- Image viewer with fit, zoom and pan, and "open in system app".
Chat images
- Markdown images outside the workdir, at ~/, C:\ and file:// paths render, open
in the viewer, and offer "open original" (pictures only).
- Images returned by tools such as Read appear as thumbnails under the call.
Hardening found in review
- previewFsUrl escapes each path segment; a double-escaped %2e%2e used to leave
/preview-fs/<session>/.
- The CORS, API timing and remote-access header decorators set headers in place.
Rebuilding the response buffered whole files in memory and dropped
Content-Length.
- The engine owns the pdf.js worker, so closing one document no longer fails the
next open.
- Office archives are inflated in steps to check their real sizes, not the sizes
they declare.
- A viewer that fails to load stays in its panel instead of taking the window down.
Adds pdfjs-dist, docx-preview, xlsx (SheetJS 0.20.3 tarball) and fflate as
renderer dev dependencies; Vite bundles them.
Refs #1397
The site had drifted from the product. Every screenshot predated the
v0.5.0 UI redesign, the reading experience shipped no search and no
syntax highlighting, and a third of the pages were internal process
artefacts — migration task lists addressed to agentic workers, a
release runbook, a proposal marked "historical".
Reorganise around the only two people who read this: someone getting
the desktop app running for the first time, and someone reading the
source. Five sections replace nine — start / desktop / im / cli /
internals — and the pages that served neither reader are gone.
Site rewrite:
- Palette lifted from the desktop app's 「纸·墨·印」 themes, so the
site and the product read as one thing. Light mirrors 纯白, dark
mirrors 墨夜, and dark mode exists at all now.
- Fonts are self-hosted. The old @import from Google Fonts is
unreachable from mainland China, which left every heading in a
fallback serif; it also only requested weight 600 while the CSS
asked for 900, so Latin and CJK in the same heading disagreed.
- Docs were shipped as one 968KB manifest downloaded on every page
view. Split into a 32KB index plus one lazily imported chunk per
page; the entry bundle is now 101KB gzipped.
- Add search, syntax highlighting, per-route meta with canonical and
hreflang, a sitemap, and an error boundary. Replace the 44vh
mobile sidebar with a drawer.
- Image dimensions are read at build time and written into the tag,
so lazy images reserve their space instead of collapsing.
Screenshots are recaptured from a real v0.5.0 build against a clean
demo project, with tokens, QR codes and paired accounts redacted.
The previous set is deleted rather than kept alongside.
Routes follow file paths, so the restructure would have broken every
inbound link; 37 old paths redirect, in both languages. The PR policy
gate and CODEOWNERS also hardcoded docs/guide/contributing.md.
Verified: check:docs 78 pages / 323 links / 0 problems, check:policy
127 pass. Walked every route at 1440 and 390 in both themes for
overflow, contrast, keyboard reachability and focus management.
