The pure white appearance option needed to avoid warm-theme leakage while preserving the existing warm classic brand theme. This adds the white theme mode, keeps local browser startup from reusing stale H5 server URLs in dev, and moves visible legacy warm surfaces onto theme tokens.
Constraint: H5 server auth policy, CORS policy, SDK routes, adapter routes, and IM access paths must not change for a visual theme fix
Rejected: Rename the original light theme to pure white | the original theme is a warm classic palette, not a neutral white workspace
Confidence: high
Scope-risk: moderate
Directive: Keep structural white-theme borders neutral; reserve the warm brand color for selected states, primary actions, and small accents

Tested: Browser smoke at http://127.0.0.1:5173 with data-theme=white, no H5 token prompt, /status inspector visible, inspector border #DDE3EA
Not-tested: Full bun run verify gate
The session inspector reused a one-off light palette, so /status, /cost,
and /context could render bright panels inside the dark desktop shell.
This moves the inspector and MCP switch control onto theme-scoped tokens
while preserving the existing light-theme look.
Constraint: Desktop dark mode must keep the existing surface hierarchy and avoid changing global brand colors.
Rejected: Recolor the shared Material palette | too broad for a component-specific regression.
Confidence: high
Scope-risk: narrow
Directive: Keep slash inspector surfaces on semantic theme tokens; do not reintroduce fixed light hex classes.
Tested: cd desktop && bun run lint
Tested: cd desktop && bun run test src/__tests__/pages.test.tsx src/__tests__/mcpSettings.test.tsx
Tested: cd desktop && bun run build
Tested: agent-browser screenshots for /status, /usage, /context, and MCP settings on http://127.0.0.1:5184/
The desktop Settings flow needed a real shell for bundled CLI setup, but the
restart path could hang behind old PTY teardown. Wire an xterm.js panel to a
portable-pty backend, inject the bundled CLI into the shell bootstrap, and
switch to the new session before cleaning up the previous one so restart work
stays off the frontend critical path.
Constraint: The desktop app must ship its own CLI entrypoint instead of depending on a global Claude install
Constraint: PTY teardown must not block the Tauri invoke path
Rejected: Reuse the install chat for arbitrary shell commands | it does not provide a real interactive PTY
Rejected: Close the old PTY before adopting the new session | it keeps restart vulnerable to hung child shutdown
Confidence: medium
Scope-risk: moderate
Reversibility: clean
Directive: Keep PTY teardown off the invoke path and preserve session handoff ordering when changing terminal lifecycle code
Tested: bunx vitest run src/__tests__/terminalPanel.test.tsx src/components/settings/TerminalPanel.restart.test.tsx; bun run lint; cargo check
Not-tested: End-to-end command echo inside the packaged desktop terminal still needs follow-up runtime verification
The reconnect action could succeed, but the detail and edit views gave almost no page-level feedback beyond the button spinner. Mirror the reconnect lifecycle into the visible status surfaces so users can tell immediately that the request is in flight and whether it settled.
Constraint: Reconnect feedback must be visible without waiting for the list row to refresh
Rejected: Rely on toast only | too late and too easy to miss while staying on the detail page
Rejected: Add a separate transient banner | duplicates the existing status surfaces instead of updating them
Confidence: high
Scope-risk: narrow
Reversibility: clean
Directive: Keep reconnect state reflected in the page-level status badge and status field, not just the action button
Tested: cd desktop && bun run test -- mcpSettings.test.tsx; cd desktop && bun x tsc --noEmit --ignoreDeprecations 5.0
Not-tested: Manual desktop click-through against a live MCP reconnect
Desktop MCP settings was synchronously probing every configured server from /api/mcp, which made the list page scale with connection latency and surface brittle behavior as installs accumulated more MCPs. Return lightweight snapshot rows from the list API, keep explicit status checks separate, and let the desktop UI refresh status in a constrained background lane while preserving project-aware server identity.
Constraint: MCP list must stay responsive even with many configured servers
Rejected: Probe all servers from the list view without limits | still fans out with server count and can overload slow installs
Rejected: Keep servers permanently unchecked until detail view | misses the desired loading feedback when the MCP page opens
Confidence: high
Scope-risk: moderate
Reversibility: clean
Directive: Keep /api/mcp as a configuration snapshot endpoint; do not reintroduce per-row live connect work on list load
Tested: bun test src/server/__tests__/mcp.test.ts; cd desktop && bun run test -- mcpSettings.test.tsx; cd desktop && bun x tsc --noEmit --ignoreDeprecations 5.0
Not-tested: Real desktop interaction against an environment with dozens of live MCP servers
Desktop plugin details now route into the shared Skills, Agents, and MCP management surfaces instead of maintaining separate read-only drilldowns. This also extends the desktop/server skill aggregation so plugin-provided skills appear in the shared list, groups MCP entries by source, and preserves detail-view back navigation based on where the user entered the page.
The implementation keeps plugin detail as the high-level capability hub while pushing real inspection into the existing management pages. Disabled plugins no longer expose false navigation paths into shared views, and the agent-browser regression script was expanded to exercise the new end-to-end flows.
Constraint: Shared Agents data only includes enabled plugin agents, so disabled plugins cannot deep-link into agent detail
Rejected: Keep duplicating full Skills/Agents/MCP detail inside Plugin detail | creates divergent UI flows and stale data paths
Confidence: high
Scope-risk: moderate
Reversibility: clean
Directive: If a detail view can be opened from multiple entry points, keep the return target in store state rather than hardcoding a single back destination
Tested: desktop vitest for plugins/skills/agents/mcp; desktop tsc --noEmit; desktop vite build; server skills API test; agent-browser web regression on plugin->skill/mcp and plugin->agent back navigation
Not-tested: packaged desktop app regression after rebuilding the Tauri bundle
Desktop MCP management now has a working server API, a global-only settings surface,
and slash-command entry points that surface MCP and skills from the composer before
routing users into the right settings view.
Constraint: Project-scoped MCP browsing in settings was too slow and noisy because it scanned multiple workdirs
Rejected: Keep project MCP aggregation on the settings homepage | duplicated entries and poor responsiveness
Rejected: Route /mcp directly on Enter without an intermediate card | removed the user's ability to choose a specific target first
Confidence: medium
Scope-risk: moderate
Reversibility: clean
Directive: Keep settings focused on global MCP; add project-scoped MCP affordances in the chat-context slash surfaces instead of re-expanding the settings homepage
Tested: bun test src/server/__tests__/mcp.test.ts; cd desktop && bun run test -- pages.test.tsx mcpSettings.test.tsx; cd desktop && bun x tsc --noEmit --ignoreDeprecations 5.0
Not-tested: Manual IAB verification after this final commit/merge cycle
