The panel stored notes, todos and plans inside one shared JSON file that
six unrelated domains also wrote to, synchronised itself through window
CustomEvents, and could only read plans. It is now Project knowledge:
server-owned storage with explicit routes, a store with rollback, a
section sidebar, plans that open and edit in place, and search across
all of it.
Notes and plans the user pins travel with every message sent in that
project. Pinning is project state, not an attachment to one message, so
it holds until unpinned and the work status panel names what is riding
along and can detach it.
Agent memory is added alongside, in two scopes: what is true about the
user, and what is true about this codebase. The split is not cosmetic —
a wrong project fact costs one project and is noticed, while a wrong
global fact quietly shapes every session everywhere and the user has no
code to check it against. It stays separate from notes so an agent
mistake cannot land in what the user wrote. Sessions receive an index of
titles only; bodies are read on demand, because an index carrying full
text grows until it crowds out the conversation.
Deciding what a session must be told, and whether it has been told, now
lives on the server. The client owned it before, which meant sessions
started without a UI — scheduled tasks, sessions the agent dispatches —
received nothing at all, and a tab's record of what it had sent outlived
the conversation: after compaction the agent no longer held the block
while the tab went on believing it did. What was delivered is recorded
in the session's own metadata, and compaction restores it through the
runtime that already restores pinned messages, in the same turn.
Agent memory ships dark behind OPENCHAMBER_MEMORY_ENABLE: unset, there
is no tool, no routes, no session index, no settings row and no panel
tab. Absent rather than switched off, so nothing invites turning on a
feature that has not been announced. Pinned notes and plans are
unaffected and ship as normal.
The preview panel worked by proxying a dev server through OpenChamber's own
origin and rewriting the HTML that came back. Anything the rewriter did not
anticipate broke, and pages that refuse to be embedded never loaded at all.
This deletes the proxy (-1604 lines and its tests) and merges the preview and
browser panels into one surface backed by a real Chromium view.
What the panel is now
- A `<webview>` in its own session partition: logins and cookies persist, hot
reload works because nothing is rewritten, DevTools are one click away.
- Annotation: pick one element, drag a region, or draw freehand, write a note,
and it reaches chat with a screenshot of the visible page with the marks on it.
- Toolbar: hard reload, page zoom, device sizes, a light/dark switch that
applies to the page rather than the app, and cookie/cache clearing scoped to
the panel alone.
- Several pages at once, each tab showing the page's own favicon, and an address
bar that suggests pages already visited in this project.
- Dev servers are listed from what is actually listening on the machine, checked
against what a project announced, so a server is offered no matter how it was
started. One that is still starting is waited for instead of failing.
Remote dev servers
The desktop app binds a local port and pipes raw bytes to the OpenChamber host
over the existing authenticated connection, so the page keeps its own origin at
the root of its own host. The reachable set is exactly what discovery reports
and is re-checked per connection, so an authenticated client cannot dial
arbitrary local services on the host. Links and redirects to another loopback
port stay on the machine that served the page. A tunnel that cannot be opened is
reported; it is never replaced by the plain loopback URL, which would answer
from the user's own machine under a remote address.
Agent control
Browser actions are a separate `openchamber_web` tool: open, snapshot, click,
type, scroll, inspect computed styles, resize between mobile/tablet/desktop, and
capture a screenshot into `.openchamber/screenshots/` in the project. The
existing `openchamber` tool keeps sessions, worktrees and scheduled tasks. Each
has its own setting in the new Settings -> General -> OpenChamber Tools section,
and the plugin is not injected at all when both are off.
Capability belongs to the connected client, not to configuration: a client
declares on its event stream that it can drive a page, which only a Chromium
host does. Exactly one client performs each request — it claims the request
before acting, and the first claim wins — because deciding by whose result
arrives first would be too late for a click that already happened. No client
listening is answered immediately with an explanation rather than a timeout.
Runtime boundaries
Web tabs get a plain iframe that can display a page but not inspect one. The
VS Code extension no longer offers the surface at all, since nothing that makes
the panel worth having works there. Mobile is unaffected.
Native boundary
Camera, microphone, location and device-picker requests from panel pages are
denied — Electron grants them by default when no handler is set, and the panel
loads whatever address the user types. Page capture, appearance emulation and
storage clearing verify that their target belongs to the panel's own session
instead of trusting a web-contents id from the renderer.
Persisted state
Stored `preview` tabs migrate to `browser` (v13 -> v14). Context panel tab
limits are now per surface, so filling one surface no longer evicts another's
tabs. Address history is stored per project and per runtime.
Documentation
`preview.mdx` and `desktop-browser.mdx` rewritten across all locales, the agent
tool settings path corrected, new `DOCUMENTATION.md` for the browser-control
broker and the dev tunnel, and the `ui-api-decoupling` skill updated where it
still described the deleted proxy.
Guard FilesView autosave until the selected file has finished loading,
refuse binary/PDF/office/archive text saves, and add a persisted global
autoSaveEnabled setting (default true) under Settings → General.

Add a shared OpenChamber control service with two thin adapters — a native
`openchamber` tool injected into managed OpenCode, and new CLI commands — so
users can manage parallel sessions, worktrees, and scheduled tasks
conversationally through agents or from the terminal.
Control plane:
- New openchamber-control service owning a fixed action contract:
projects.list, models.list, session list/create/send/fork/status/messages,
and schedule list/create/run/delete/toggle. Session and worktree deletion
and project registration are deliberately not exposed.
- New openchamber-sessions module owning create/worktree/prompt orchestration,
Goal Mode dispatch, wait semantics (initial idle never counts as completion;
timeout and cancellation are failures), and explicit partial-failure results.
- Scheduled-task logic extracted into a service shared by routes, CLI, and the
agent tool.
Agent tool:
- Managed OpenCode gets a materialized plugin registering one typed tool with
a loopback-only callback, per-child ephemeral bearer (timing-safe, never
persisted or logged), and abort propagation into the service.
- The ~1.5k-token schema applies progressive disclosure: short descriptions,
server-side validation returning actionable usage errors, and intent
guardrails — created sessions/tasks are user-facing work (not age
self-delegation); worktree/goal/agent/variant/wait are omit-by-default;
dispatches produce no completion notification, and later result r
to session.messages, which now returns the authoritative sessionStatus.
- session.create without a user-named model picks from favorites/re
send/fork omit the selection and the service reuses the target session's
last user-message model, agent, and variant before falling back t
- An "Agent control tool" setting (default on, Save + Reload to apply)
disables plugin injection entirely.
CLI:
- New `openchamber session`, `schedule`, `projects`, and `models` commands
with automatic instance targeting, --wait/--timeout/--last-assist
worktree flags, and Goal Mode, preserving interactive, non-TTY, --quiet,
and --json contracts. The control HTTP timeout derives from the w
instead of the 4-second default.
UI:
- New built-in "Schedule a Task" starter (/schedule-task) running a
dialogue that defines a task and offers to create it via the tool after
explicit confirmation; Craft a Goal and Feature Planning gain the
handoff offer, and guided starters reserve the question tool for concrete
option choices. Localized in all 10 locales, migrated into custom
starter lists, hidden on VS Code.
- Sidebar shows CLI/agent-created sessions live via the control eve
- openchamber tool calls render with per-action titles and metadata.
* feat: add draw.io diagram editor integration
Embed draw.io editor via react-drawio (MIT, zero deps) for inline
editing of .drawio files. Changes auto-save to disk. Includes
inline editor in FilesView with Visual/Source toggle, dark mode
support, template picker for new files, and chat file attachment
integration.
* fix: debounce diagram autosave to prevent reload loop
* fix: ignore watcher-triggered xml prop changes to prevent reload loop
* fix: remove auto-save-to-disk, add manual save button for diagrams
Autosave writes triggered file watcher cascade that reloaded the
draw.io iframe and reset zoom. Replaced with explicit Save button
in the toolbar (floppy disk icon). Editor XML is stable on mount
and ignores watcher-triggered prop changes.
* fix: remove auto-save write from DiagramView, add save button
* fix: hide draw.io save/exit buttons in editor
* fix: also hide save-and-exit button
* fix: brighten save button styling, add saved confirmation
* fix: remove autoSaveStatus toggle on diagram save to prevent toolbar collapse
* fix: add local save confirmation state for diagram button
* fix: remount drawio iframe on theme change, persisting XML across mounts
* fix: clear persisted xml on mount to prevent leaking between files
* fix: initialize dark mode synchronously, preserve edits across theme remount
* fix: auto-focus drawio iframe on mount/theme-change for keyboard shortcuts
* fix: add diagram i18n keys to Traditional Chinese locale
* fix: restore upstream HMR host and LAN address support
* fix: load sub-agent sessions on bootstrap for sidebar visibility
Two-phase session load: first fetch root sessions (for accurate
sessionTotal), then fetch all sessions and include child sessions
(sub-agent delegations). This ensures sub-agent sessions appear
in the sidebar immediately instead of relying on the async global
session store.
* remove opencode-drawio from PR branch
* fix: atomic file writes to prevent concurrent read/write truncation
Three-layer defense against the O_TRUNC race:
1. Write side (server): replace direct writeFile with write-to-temp-
then-rename. fs.rename is atomic on POSIX.
2. Read side (server): retry up to 3 times with 50ms backoff when
readFile returns empty but stat reported non-zero size.
3. FilesView client: refuse to save empty draftContent when the
original fileContent was non-empty.
* fix(dev): clean up orphaned OpenCode processes on Ctrl+C
* fix: allow empty file saves, log warning instead of blocking
Replaces the hard block on saving empty content with a console.warn.
The atomic write + read retry on the server side handle the O_TRUNC
race properly. The previous guard caused a UX regression by silently
preventing users from clearing a file and saving.
* fix: remove time window from sub-agent fallback for live tasks
While a task tool is active, the fallback now matches any session
with the correct parentID regardless of creation time. This allows
late-appearing child sessions to be found when the OpenCode server
is slow or the SSE event pipeline is delayed. The time window is
still applied once the task tool has completed, as a final sanity
check.
* fix: three diagram editor bugs from Greptile review
1. stableXmlRef now resets when xml prop changes — switching
between .drawio files renders the correct content.
2. Focus effect only runs on mount, not on isDark changes —
theme toggle no longer steals keyboard focus 600ms later.
3. saveDiagram updates xml state after writing — dirty-check
guard works correctly for subsequent saves.
* fix: route session.created SSE events to correct directory
Three-layer fix for sub-agent sessions not appearing in sidebar and
inline chat:
1. protocol.js: parseSseEventEnvelope now extracts directory from
properties.info.directory (where session.created/updated events
carry it) in addition to properties.directory. WS frames relayed
to the browser now carry the real directory instead of 'global',
so child sessions routed to the correct directory store.
2. event-pipeline.ts: same fallback in resolveEventDirectory for
defense-in-depth when SSE events bypass the WS relay.
3. resolveFallbackTaskSessionId.ts: time window lower bound now
allows 2s grace before taskStartTime to accommodate server timing
jitter (child session creation timestamps consistently precede the
tool's recorded start by ~6-9ms), fixing the 'Open subtask'
button not rendering in OpenChamber's inline chat.
* fix: sub-agent sidebar visibility, file zeroing guard, inline badge fallback
- Sync watchdog: periodic child session discovery poll (every 15s) detects
sessions created by other OpenCode instances, triggers parent materialization
- protocol.js: parseSseEventEnvelope extracts directory from
properties.info.directory for session.created/updated events
- event-pipeline.ts: same fallback in resolveEventDirectory for defense-in-depth
- resolveFallbackTaskSessionId: don't require taskStartTime (cross-OpenCode);
pick most recent child when multiple idle candidates exist
- readTaskSessionIdFromOutput: parse <task id="ses_xxx"> format from output
- FilesView: reinstate empty-draft guard (block save when draftContent='' but
fileContent had content) to prevent file zeroing on tab switch
* Fix diagram autosave reload loop
* Highlight drawio files as XML
* Use diff-compatible highlighting for drawio files
* Restore drawio file icon mapping
* Stabilize drawio source preview toggle
