The release collects the post-v0.1.8 desktop workspace manager work, provider compatibility fixes, WebSearch fallback support, and desktop lifecycle hardening into a tagged GitHub Actions release.
Constraint: GitHub Release body is sourced from release-notes/v0.1.9.md in the tagged commit
Constraint: The release script owns version bumps for desktop/package.json, Tauri config, Cargo.toml, and Cargo.lock
Rejected: Push the script-generated generic release commit | it would violate the repository Lore commit protocol
Confidence: high
Scope-risk: narrow
Directive: Do not move v0.1.9 without rerunning the release preflight and verifying the tag commit contains release-notes/v0.1.9.md
Tested: bun run scripts/release.ts 0.1.9 --dry
Tested: bun run scripts/release.ts 0.1.9
Tested: cd desktop/src-tauri && cargo check
Not-tested: GitHub Actions release workflow before tag push
The chat timeline lost per-turn changed file cards when the visible user message ids did not match persisted transcript ids, and sessions without SDK file-history snapshots had no fallback source for turn changes. Match live cards by stable user-message index when needed and derive checkpoint previews from transcript tool calls when snapshots are absent.
Constraint: Right-side workspace changes already derive from transcript tool calls, so chat checkpoint data must remain consistent with that source.
Rejected: Force a history reload after every turn | would hide the id mismatch but add churn and still not cover transcript-only sessions.
Confidence: high
Scope-risk: moderate
Directive: Keep snapshot checkpoints as the preferred source, and use transcript extraction only as the compatibility fallback.
Tested: bun test src/server/__tests__/sessions.test.ts

Not-tested: Browser E2E against a live model session.
The desktop workspace panel and chat transcript were mixing project-level file state with per-turn session history, which made rewind, file attachment, and changed-file previews brittle across multi-turn and historical sessions. This keeps turn checkpoints durable in the transcript, makes workspace refreshes happen at the right lifecycle points, and hardens long file previews without blocking the UI.
Constraint: Right-side workspace changes are project working-tree state, while chat turn cards are session checkpoint state.
Rejected: Treat every changed-file panel entry as session-local | new sessions must still reveal existing dirty project files.
Confidence: high
Scope-risk: moderate
Directive: Do not couple global workspace status to session checkpoint cards without preserving both product meanings.

Not-tested: Packaged Tauri runtime smoke test
The WebSearch settings footer placed explanatory copy and the save action in one flex row. On narrower dark-mode layouts, the long localized hint could squeeze the button enough for Chinese text to wrap vertically.
Move the action onto its own right-aligned row and give the button a stable minimum width so the layout remains readable across localized settings screens.
Constraint: Settings screen must support Chinese dark-mode copy without vertical button text.
Rejected: Only widening the button in the same flex row | the hint text can still consume the row and compress the action.
Confidence: high
Scope-risk: narrow
Directive: Keep localized action buttons out of compressible text rows unless the container has explicit width guarantees.
Tested: cd desktop && bun run lint
Tested: agent-browser visual check in light and dark settings pages
The desktop start screen can already collect a project directory before the first chat turn, but workspace management is intentionally session-scoped. Creating a draft session immediately after project selection keeps the file manager, changed-file view, runtime selection, and terminal toolbar on the same path users see after sending the first message.
Constraint: Workspace file management state is keyed by session id.
Rejected: Add a separate non-session workspace mode | it would duplicate panel state and create a second lifecycle to maintain.
Confidence: high
Scope-risk: narrow
Directive: Keep workspace management session-scoped; create or reuse a session before exposing the workspace panel.

Not-tested: Native Tauri folder dialog manual smoke test.
Native Anthropic web search is only reliable for Claude-family model names,
while many configured providers either do not implement the server tool schema
or reject it through proxy layers. This routes WebSearch through a single
resolver, adds Tavily and Brave fallbacks, and exposes provider key setup in
the desktop settings page.
Constraint: Third-party Anthropic-compatible endpoints may reject web_search_20250305 even when the model name is Claude-like
Constraint: Non-Claude models still need a usable WebSearch path when users configure an external search provider
Rejected: Gate native WebSearch by base URL | third-party Claude proxies can support it and official-looking URLs are not the real capability boundary
Rejected: Always expose Anthropic native WebSearch | unsupported providers loop on schema or tool errors
Confidence: high
Scope-risk: moderate
Directive: Keep WebSearch capability resolution centralized in WebSearchTool/backend.ts before adding more search providers
Tested: bun test src/tools/WebSearchTool/backend.test.ts
Tested: cd desktop && bun run test -- generalSettings.test.tsx
Tested: cd desktop && bun run lint

Tested: agent-browser Settings E2E for Tavily/Brave links and settings persistence
Tested: live Tavily and Brave fallback searches returned results using transient keys
Not-tested: automatic LLM decision to invoke WebSearch end-to-end against a paid model session
Desktop users can now disable thinking for new sessions, and Anthropic-compatible providers that opt in receive explicit disabled-thinking requests across main turns, side queries, and AI title generation.
Constraint: DeepSeek/Kimi/GLM Anthropic-compatible endpoints need a non-thinking path without scattering provider-specific logic through the CLI.
Rejected: Per-model if/else branches | centralized provider preset env keeps the native CLI surface smaller and easier to audit.
Confidence: high
Scope-risk: moderate
Tested: bun test src/utils/__tests__/thinking.test.ts src/server/__tests__/title-service.test.ts src/server/__tests__/provider-presets.test.ts src/server/__tests__/conversations.test.ts

Tested: agent-browser DeepSeek desktop E2E with transparent proxy captured main and title requests with thinking.type=disabled
Desktop sessions can carry persisted runtime provider selections long after the provider index changes. The server now validates those session-level and active provider ids before launching the CLI, falls back to a valid default path, and includes non-secret launch diagnostics in startup failure messages so future issue reports expose the server-side context.
Constraint: Desktop users often report only the visible chat error, not sidecar console logs
Rejected: Frontend-only cleanup of stale localStorage selections | does not protect API or reconnect paths and loses server-side evidence
Confidence: high
Scope-risk: narrow
Directive: Do not pass session-scoped provider ids into CLI startup without validating they still exist in providers.json

The macOS icon rendered smaller than neighboring Dock icons because the
source artwork left a 120px margin on the 1024px canvas. Scale the macOS
source to the expected 96px margin and regenerate the Tauri icon set so
bundled app assets stay in sync.
Constraint: macOS source artwork should fit a 1024px canvas with 96px icon spacing
Rejected: Adjust only the Dock screenshot or public preview asset | packaged icon.icns would remain undersized
Confidence: high
Scope-risk: narrow
Directive: Regenerate desktop/src-tauri/icons when changing app-icon-macos.svg
Tested: cd desktop && bun run lint
Tested: icon.icns expanded 1024px image reports 96px margins on all sides
Not-tested: Full macOS app rebuild
Windows users reported that the desktop window lost its size and position after restarting, and hidden windows could behave inconsistently when restored from taskbar/tray interactions. The Tauri shell now records the main window bounds in the app config directory, restores them on startup, and skips stale off-screen states when monitor layouts change.
Constraint: Avoid new dependencies for window state persistence
Constraint: Preserve existing hide-to-tray behavior for the main window
Rejected: Add tauri-plugin-window-state | larger dependency surface for one small main-window state file
Confidence: medium
Scope-risk: moderate
Directive: Keep monitor visibility checks when changing restore behavior so external-display removal does not strand the window off-screen
Tested: cargo test
Tested: cd desktop && bun run lint
Tested: cd desktop && bun run build
Not-tested: Windows taskbar manual reproduction; current machine is macOS
Not-tested: cd desktop && bun run test fails in existing frontend locale assertions unrelated to this Tauri change
The workspace panel now treats an empty changed-files status as a browsing case, so opening the panel shows the project tree instead of an empty changed-files view. The panel header controls were also reduced to keep the right workspace rail visually proportional in compact layouts.
Constraint: Users still need to manually inspect the empty changed-files view when they explicitly choose it.
Rejected: Always render the empty changed-files state | it makes the opened workspace feel broken when no files changed.
Confidence: high
Scope-risk: narrow
Directive: Do not auto-switch the workspace view after a user has explicitly selected a workspace view.
Tested: cd desktop && bun run test -- src/components/workspace/WorkspacePanel.test.tsx src/stores/workspacePanelStore.test.ts
Tested: cd desktop && bun run lint
Tested: cd desktop && bun run build
Not-tested: Browser E2E visual screenshot pass was not rerun for this small header sizing change.
The chat surface now relies on the current-turn changes card for file rollback, so the older per-message hover rewind affordance was removed to avoid two competing rollback models.
Constraint: Current-turn undo still depends on the existing checkpoint rewind API.
Rejected: Keep both rewind entry points | duplicate rollback affordances make the product harder to explain and test.
Confidence: high
Scope-risk: moderate
Directive: Prefer adding rollback behavior through the current-turn change card instead of restoring per-message hover rewind.
Tested: bun test src/server/__tests__/sessions.test.ts
Tested: cd desktop && bun run test
Tested: cd desktop && bun run lint
Tested: cd desktop && bun run build
Not-tested: Browser E2E scripts were updated but not executed in this commit.
The session workspace and current-turn undo surfaces now have regression coverage for multi-turn rollback semantics, stale current-turn cards, and dark theme workspace token usage.
Constraint: Workspace rollback must behave consistently for git and non-git session review flows.
Rejected: Rely on manual browser-only checks | they do not guard future regressions.
Confidence: high
Scope-risk: narrow
Directive: Keep rollback tests focused on target user message identity, not only visible index position.

Not-tested: Full live multi-turn assistant generation E2E across a fresh temporary project.
Workspace inspection now shares the same diff renderer between chat change cards and panel previews, supports scoped preview-tab closing, confirms checkpoint undo, resolves rewind checkpoints from the prompt cwd, and removes light-only workspace chrome so dark theme remains coherent.
Constraint: Workspace review must keep working for existing transcript sessions and non-git session-derived changes.
Rejected: Keep a separate chat diff preview | it drifted from panel rendering and dark theme behavior.
Confidence: high
Scope-risk: moderate
Directive: Keep chat and workspace diff rendering shared so theme and truncation behavior do not diverge again.

Not-tested: macOS packaged app build
Workspace file preview is a local desktop surface, so image files should not be blocked by the text preview byte cap. Large text files now return a bounded preview instead of an unusable too-large state, while binary files remain explicitly unsupported.
Constraint: Avoid unbounded text payloads that can freeze the desktop renderer
Rejected: Remove all read limits | large generated files can still overload JSON transport and syntax rendering
Confidence: high
Scope-risk: moderate
Directive: Keep image preview detection before text-size limiting so local images remain renderable
Tested: bun test src/server/__tests__/workspace-service.test.ts

Not-tested: Full packaged macOS smoke after this commit
Workspace inspection was visible only as a side panel, while file restore still lived behind the older per-message rewind affordance. This adds a chat-flow change card for the completed turn, keeps undo routed through checkpoint rewind, and tightens the workspace split layout so narrow and fullscreen windows keep both chat and file preview usable.
Constraint: Current session file changes must work for non-Git directories when transcript tool edits are available
Constraint: Workspace preview must remain right-docked without horizontal overflow across narrow and wide desktop viewports
Rejected: Keep only hover rewind | users could not clearly see what the current turn changed before undoing it
Rejected: Use Git as the only changed-file source | many desktop sessions run in temporary or non-Git directories
Confidence: high
Scope-risk: moderate
Directive: Keep checkpoint rewind as the source of truth for undo semantics; workspace diffs are a preview surface, not the restore authority
Tested: bun test src/server/__tests__/sessions.test.ts src/server/__tests__/workspace-service.test.ts

Expose a workspace inspector for desktop sessions so users can browse the active project, preview files, inspect session-derived changes, and review diffs even when the work directory is not a git repository.
Constraint: The workspace view must work for temporary and non-git project directories.
Rejected: Rely only on git status | non-git sessions would lose the changed-files surface.
Confidence: medium
Scope-risk: moderate
Directive: Keep undo semantics separate from workspace browsing; checkpoint-backed rewind should remain the source of truth for rollback.

Add a bottom README callout that makes the GitHub star ask visible while embedding the live Star History chart in both Chinese and English docs.
Constraint: Keep bilingual README footer sections aligned.
Confidence: high
Scope-risk: narrow
Tested: Verified Star History SVG endpoint returns 200 image/svg+xml.
Not-tested: Full docs site build; README-only content change.
Most reports now come from desktop users, so the templates need to collect the operating system, desktop version, reproduction path, configuration screenshots, and logs before maintainers can diagnose failures.
Constraint: Desktop releases are the dominant support surface for external users
Rejected: Keep CLI-first fields at the top | it delays collecting the information needed for Windows and macOS desktop failures
Confidence: high
Scope-risk: narrow
Directive: Keep desktop OS and app version fields near the top of future issue template edits
Tested: git diff --check -- .github/ISSUE_TEMPLATE/bug_report.md .github/ISSUE_TEMPLATE/question.md
Not-tested: GitHub issue form rendering in browser
Closing the desktop window should not tear down the local server when users expect the app to keep serving background work. The Tauri layer now owns that lifecycle: close hides the main window, tray actions restore or quit, and true quit paths still stop sidecars.
Constraint: Issue #213 asks for Windows close-to-background behavior, and macOS should follow the same desktop lifecycle.
Rejected: Frontend-only close handling | native window close events and OS menu actions need one Tauri-owned path.
Confidence: high
Scope-risk: moderate
Directive: Do not remove the explicit quit marker unless all updater, tray, and app-exit paths are rechecked.
Tested: cargo fmt --manifest-path desktop/src-tauri/Cargo.toml --check

The release note is now the GitHub Release source of truth, and the desktop version files have been moved together so the tag-triggered workflow can package the same version consistently.
Constraint: release-desktop.yml reads release-notes/v0.1.8.md from the tagged commit
Rejected: Push tag without a release commit | workflow requires version files and notes in the tag
Confidence: high
Scope-risk: narrow
Reversibility: clean
Directive: Keep the release notes filename aligned with the tag before pushing future releases
Tested: bun run scripts/release.ts 0.1.8 --dry
Tested: bun run scripts/release.ts 0.1.8
Not-tested: Remote GitHub Actions build before pushing the tag
The session inspector now asks the resumed CLI for a fast structural context estimate instead of forcing the full token-counting API path. This preserves live CLI state for system prompt, tools, MCP tools, skills, and messages while avoiding the 20s timeout that made historical sessions appear stuck or fall back to transcript-only estimates.
Constraint: Inspector requests must return quickly for third-party providers and historical resumed sessions.
Rejected: Increase the server timeout | the slow path can still block on provider token counting and keeps the UI feeling broken.
Confidence: high
Scope-risk: narrow
Directive: Keep interactive inspector context on the estimateOnly control path unless the UI explicitly supports a slow precise refresh.
Tested: bun test src/server/__tests__/conversations.test.ts -t 'structured session inspection|Sonnet 4.6 transcript usage'
Tested: cd desktop && bun run test -- --run src/i18n/index.test.tsx
Tested: cd desktop && bun run build
Tested: direct /api/sessions/:id/inspection?includeContext=1 returned live context in 0.046867s with System prompt, System tools, MCP tools, Messages
Tested: agent-browser automation verified no loading/error and visible System prompt/System tools/MCP tools/Messages
Not-tested: bare root tsc --noEmit, because current tsconfig scans existing desktop/src-tauri/target generated binary assets unrelated to this change
Session inspection was coupling quick status and usage rendering to live context control requests, so a slow get_context_usage path could leave the desktop inspector stuck on a loading state. The desktop panel now loads basic inspection data first, renders a transcript-based context estimate immediately, and only asks for live context details as a background refinement.
The translation hook now returns a stable function per locale so effects that depend on translation do not reset and re-fetch after every render.
Constraint: Third-party provider sessions may not expose reliable live context capabilities through the control request path.
Rejected: Keep waiting on live get_context_usage for the context tab | it recreates the user-visible loading stall.
Rejected: Hardcode provider-specific context windows | provider capabilities are not always known from the desktop session record.
Confidence: high
Scope-risk: moderate
Directive: Do not make the inspector first render depend on live CLI control requests without a transcript or cached fallback.
Tested: bun test src/server/__tests__/conversations.test.ts -t "structured session inspection|Sonnet 4.6 transcript usage"
Tested: cd desktop && bun run test -- --run src/i18n/index.test.tsx
Tested: cd desktop && bun run build
Tested: git diff --check
Tested: agent-browser verified /context renders transcript estimate without Loading context data
Not-tested: Provider-specific true context-window discovery for every third-party vendor
Default desktop sessions with an active third-party provider were only passing the selected model into the CLI startup path. That allowed the child CLI to fall back to stale cc-haha settings env instead of the provider index, so the UI-selected provider could diverge from the key and endpoint used by the subprocess.
Route default sessions through the active provider id and make third-party Sonnet capability overrides explicit with a non-empty sentinel. This keeps provider runtime env sourced from providers.json and avoids treating third-party Sonnet models as first-party thinking-capable models.
Constraint: Third-party provider behavior is the product baseline for desktop users.
Rejected: Rely on synced cc-haha/settings.json env | it can be stale and caused provider/key routing mismatches.
Confidence: high
Scope-risk: narrow
Directive: Third-party desktop sessions must carry providerId into ConversationService; do not depend on global settings env for active providers.
Tested: bun test src/server/__tests__/conversations.test.ts src/server/__tests__/conversation-service.test.ts src/server/__tests__/provider-presets.test.ts src/utils/__tests__/thinking.test.ts
Tested: git diff --check
Third-party Anthropic-compatible providers can expose Claude model names without supporting every first-party runtime capability. Desktop sessions now preserve provider-specific capability overrides, keep selected provider runtime state across reconnects and restarts, and keep the provider dialog behavior aligned with the updated presets.
Constraint: Custom ANTHROPIC_BASE_URL endpoints must not be treated as first-party Anthropic for adaptive thinking support.
Rejected: Rename provider default Sonnet models | that would hide the compatibility issue instead of fixing runtime capability detection.
Confidence: high
Scope-risk: moderate
Directive: Do not enable Claude first-party capability defaults for custom Anthropic-compatible base URLs without provider verification.

Provider setup now keeps API keys hidden by default while still allowing an explicit reveal, and the About page links users directly to release notes and issue feedback. Provider preset copy was also adjusted so promotional text stays intentional and current.

Confidence: high
Scope-risk: moderate
Reversibility: clean
Tested: cd desktop && bun run test -- generalSettings.test.tsx
Not-tested: Full desktop lint and production build
The README footer now separates community references from sponsors and donation content, so readers can see which upstream projects informed the UI stack and provider configuration approach.
Constraint: Keep acknowledgement placement near the footer without mixing references into sponsorship copy
Confidence: high
Scope-risk: narrow
Reversibility: clean
Tested: Reviewed README.md and README.en.md diff
Not-tested: Markdown site build
Provider setup now carries the metadata needed for sponsored and local Anthropic-compatible providers, while keeping provider URLs and API keys editable in the desktop form. The desktop UI also exposes API-key links, optional sponsor copy, full key visibility, and local no-key presets that can be activated into runtime settings.
Constraint: Local LM Studio and Ollama integrations require Anthropic-compatible root URLs rather than OpenAI /v1 URLs
Rejected: Keep local providers at the top of the preset list | user requested them immediately before Custom
Confidence: high
Scope-risk: moderate
Directive: Do not change local provider base URLs to /v1 without rechecking Anthropic compatibility docs

Tested: Web UI provider creation plus real sessions for LM Studio, Ollama, JiekouAI, and Shengsuanyun
Not-tested: Production packaged Tauri build
The sponsor section now reflects the active partners only, with
clickable referral copy and local logo assets so GitHub renders the
same layout in both Chinese and English READMEs.
Constraint: Chinese and English README sponsor sections must stay synchronized
Rejected: Keep LegionProxy as a lower-priority sponsor | user requested removing it
Confidence: high
Scope-risk: narrow
Tested: git diff --cached --check
Not-tested: GitHub rendered README preview
Kimi Code documents a separate Anthropic-compatible coding endpoint from the Moonshot open platform, so the built-in Kimi preset should point Claude-compatible traffic at the coding endpoint instead of the retired Moonshot anthropic path.
Constraint: Kimi Code Anthropic-compatible base URL is https://api.kimi.com/coding/ and this app appends /v1/messages at runtime.
Rejected: Use https://api.moonshot.cn/coding | official Kimi docs distinguish Kimi Code from the Moonshot open platform URLs.
Confidence: high
Scope-risk: narrow
Directive: Do not switch Kimi back to api.moonshot.cn/anthropic without rechecking current Kimi Code docs.
Tested: bun test src/server/__tests__/provider-presets.test.ts
Not-tested: Live Kimi API call with a real user key
The desktop terminal already supported independent PTY sessions, but it only lived inside settings. This change promotes it to a first-class tab workflow so users can open multiple host terminals without leaving the chat-oriented desktop layout.
Constraint: Tauri terminal sessions are process-backed and must stay mounted while switching tabs.
Rejected: Reuse the settings terminal as a navigated page only | it cannot support multiple independent terminal tabs.
Rejected: Hide inactive xterm panes with display none | xterm lost visible output after tab switches during E2E.
Confidence: high
Scope-risk: moderate
Directive: Keep inactive terminal panes mounted and avoid display none unless xterm repaint behavior is reverified.

Not-tested: Intel macOS package
Subagent transcripts are stored in sidecar JSONL files, so the desktop history loader now links completed Agent results back to their sidecar tool activity and namespaces child tool ids before rendering. The chat renderer then keeps parented tool calls and orphaned child results out of the root session stream, while the Agent result preview strips runtime metadata from the user-facing answer.
Constraint: Subagent tool activity may live under ~/.claude/projects/{project}/{session}/subagents instead of the main session JSONL
Rejected: Rely only on adjacent message ordering | interleaved messages can split parent and child tool activity
Rejected: Show final Agent output inside the expanded card | expanded cards should show process activity while the modal shows the final answer
Confidence: high
Scope-risk: moderate
Directive: Do not remove child tool id namespacing without proving multiple subagents cannot emit colliding tool ids
Tested: bun test src/server/__tests__/sessions.test.ts

Not-tested: Live streaming of sidecar subagent tool activity before the sidecar file is persisted
The model selector reused the light-theme primary fixed surface for selected rows, which made dark mode render a pale block with poor text contrast. This gives the selector its own selected-row tokens so dark mode can keep a low-luminance surface while light mode preserves the existing look.
Constraint: Keep the fix scoped to desktop theme tokens and the existing selector component
Rejected: Change primary-fixed globally | too broad because other components rely on that token semantics
Confidence: high
Scope-risk: narrow

The context tab needs both absolute token counts and percent-of-window values to stay scannable. Category rows now show the percent next to each token count, and the free-space summary card also reports remaining percent.
Constraint: Keep the compact terminal-inspired layout while restoring the numeric detail users rely on.
Confidence: high
Scope-risk: narrow

Desktop slash commands now separate local UI panels from CLI turn execution. The session inspector exposes status, usage, and context data from the active session, including transcript and context fallbacks, so /status, /cost, and /context can render structured desktop UI instead of raw terminal text. The inspector and help surfaces now use the existing desktop i18n catalogs for English and Chinese labels.
Constraint: Desktop read-only slash commands must not spawn duplicate CLI processes or depend on submitting a normal user turn.
Rejected: Render raw CLI command text in chat | it keeps terminal-specific layout constraints and does not fit the desktop panel UX.
Confidence: high
Scope-risk: moderate
Directive: Keep /status, /cost, and /context routed through the local inspector unless the CLI exposes a structured interactive command protocol.

Desktop rewind previously used the visible user-message index as the primary selector. That can drift from the persisted active chain when hidden or non-rendered user messages exist, so the API now prefers a stable user message id and checks the selected prompt text before mutating transcript or files.
Constraint: Desktop UI can hide transcript entries that still exist in the persisted session chain
Rejected: Keep index-only rewind | can target an earlier user message after UI/server chain drift
Confidence: high

The local Apple Silicon packaging script produced app bundles that could
fail strict bundle validation because the outer .app had no sealed
resources. The fix shallow-signs only the copied canonical app bundle and
checks that the claude-sidecar code-signature hash stays unchanged.
Constraint: GitHub Actions release packaging must remain on the existing tauri-action path
Constraint: macOS Keychain ACLs are sensitive to sidecar code-signature hashes
Rejected: Set macOS signingIdentity in release CI | Tauri re-signs nested sidecars and can change Keychain caller identity

The repository uses product-oriented branch prefixes rather than Codex-specific names, so the workspace guidance now records that convention for future local branch creation.
Constraint: Repository guidance should stay compact and only capture durable workflow rules.
Confidence: high
Scope-risk: narrow
Tested: not run; documentation-only change
A desktop session can pass the startup grace window and then lose its CLI subprocess before a result arrives. Previously that path only deleted the active process record, leaving the WebSocket client in an active turn with no terminal message. The process-exit handler now emits a synthetic CLI error result through the existing translation path so the UI receives both an error and message_complete. The mock SDK fixture can reproduce post-startup exits, and the integration test locks the terminal event behavior.
Constraint: The frontend already relies on result is_error translation to emit error plus message_complete.
Rejected: Add a separate WebSocket process-exit message type | it would duplicate existing result-error handling and require another frontend state path.
Confidence: high
Scope-risk: narrow
Directive: Keep process-exit failures on the same result-error path unless the client protocol gains a dedicated terminal error event.
Tested: bun test src/server/__tests__/conversations.test.ts
Tested: cd desktop && bun run lint
Tested: agent-browser against http://127.0.0.1:1421 with mock CLI late exit; page showed CLI process exited unexpectedly and composer became editable again
Desktop slash command handling needed a few follow-up guards after adding
CLI parity. Bare /clear remains a local desktop reset, but /clear with
arguments is rejected instead of silently discarding user text. Clear also
resets cached slash commands, compact boundaries preserve CLI-provided text,
and the help panel now discloses when the More section is truncated.
Constraint: Preserve the desktop /clear fast path without accepting accidental arguments
Rejected: Let /clear arguments fall through to the CLI | the CLI command still clears context and would keep the footgun
Confidence: high
Scope-risk: narrow
Directive: Keep desktop-local slash command guards in sync with CLI command argument semantics
Tested: cd desktop && bun run test src/stores/chatStore.test.ts src/__tests__/pages.test.tsx --run -t "clears local desktop chat state|ActiveSession routes /help"
Tested: bun test src/server/__tests__/conversations.test.ts
Tested: cd desktop && bun run lint
Tested: git diff --check
Not-tested: Full pages.test.tsx because unrelated locale-sensitive assertions are already present in that file
Desktop had no reliable handling for common local slash commands, so
commands like /clear, /help, /context, /cost, and /compact either looked
unresponsive or lost their CLI-specific side effects. This routes desktop
commands by behavior: local panels stay local, stateful clear resets the
session transcript, and CLI-local outputs are rendered in chat.
Constraint: Preserve existing CLI semantics for prompt, local, local-jsx, and compact slash commands
Rejected: Send every slash command through the normal chat path | local commands need desktop UI or session state side effects
Confidence: high
Scope-risk: moderate
Directive: Keep hidden aliases such as /plugins out of the visible command list unless they become canonical CLI commands
Tested: cd desktop && bun run test src/components/chat/composerUtils.test.ts src/stores/chatStore.test.ts --run
Tested: cd desktop && bun run test src/__tests__/pages.test.tsx --run -t "ActiveSession routes /plugin|ActiveSession routes /help|EmptySession slash picker includes dynamic skills"
Tested: bun test src/server/__tests__/conversations.test.ts
Tested: cd desktop && bun run lint
Tested: agent-browser E2E for /help, /plugin, /plugins, /cost, /clear, /context, /compact, /mcp, and normal text input
Not-tested: Root tsc project because it currently includes generated Tauri target assets and extracted native files
