Summary

  • add an opt-in Claude multi-account adapter backed by claude-swap / cswap
  • read cswap --list --json, require schemaVersion == 1, and expose only a provider-neutral allow-listed account snapshot
  • support explicit account activation through cswap --switch-to <slot> --json without copying or storing Claude credentials in Win-CodexBar
  • add Settings UI/configuration plus codexbar usage -p claude --all-accounts integration

Fixes #477

Safety / behavior

  • disabled by default; executable path must be explicitly configured
  • subprocesses use fixed argv arrays (no shell command construction)
  • list calls have bounded runtime/output; external labels and errors are sanitized before reaching UI/CLI
  • unknown external status values are collapsed to a non-actionable unknown state instead of being echoed
  • account switches are bounded to 5 minutes and own the Claude credential-operation mutex inside the blocking task, so a stalled helper cannot hold credential serialization indefinitely and cancellation cannot release it while the switch is still running
  • --all-accounts --brief renders one compact Claude provider line, and --status keeps provider status distinct from each account's own claude-swap status in Text, JSON, and Toon output
  • raw stderr and credential material are never surfaced or persisted by the adapter

Validation

  • pnpm --dir apps/desktop-tauri test - 60 files / 347 tests passed
  • focused Claude account + claude-swap UI tests - 8/8 passed
  • pnpm --dir apps/desktop-tauri run check-locale - 848 keys matched
  • pnpm --dir apps/desktop-tauri run build - TypeScript + Vite production build passed
  • cargo fmt --all -- --check - passed
  • git diff --check - passed
  • staged diff secret-pattern scan - no matches

Validation limitations

Local Rust test/clippy/native Tauri validation is blocked on this machine because the Windows Rust toolchain resolves link.exe to Git-for-Windows' GNU linker and the MSVC linker/build tools are not installed. Hosted Windows CI is the Rust compile/test gate. A real cswap executable is also not installed here, so subprocess behavior is covered by fixtures/unit seams rather than a live account switch. No fresh native/CUA proof is attached for the same native-build blocker.

📝 Walkthrough

Walkthrough

The change adds Claude Swap settings, a Rust adapter for account listing and switching, desktop settings controls, Tauri bridge commands, localization, and CLI support for displaying all Claude accounts.

Changes

Claude Swap adapter and settings

Layer / File(s) Summary
Claude Swap adapter contract
rust/src/providers/claude/claude_swap.rs, rust/src/providers/claude/mod.rs
Adds bounded no-shell execution, schema-v1 parsing, sanitization, account projection, switch validation, and unit tests.
Claude Swap settings and bridge types
rust/src/settings/types.rs, rust/src/settings.rs, apps/desktop-tauri/src-tauri/src/commands/bridge.rs, apps/desktop-tauri/src-tauri/src/commands/settings.rs, apps/desktop-tauri/src/types/bridge.ts
Adds Claude-only enablement and executable-path settings, persistence methods, settings update fields, snapshots, and account DTOs.

Desktop integration

Layer / File(s) Summary
Desktop account commands and wiring
apps/desktop-tauri/src-tauri/src/commands/claude_accounts.rs, apps/desktop-tauri/src-tauri/src/main.rs, apps/desktop-tauri/src/lib/tauri.ts
Adds account listing and switching commands. Switching serializes credential operations, invalidates Claude usage, and emits refresh events.
Settings UI and validation
apps/desktop-tauri/src/surfaces/settings/providers/sections/credentials/*, apps/desktop-tauri/src/i18n/keys.ts, rust/src/locale.rs, rust/src/locale/en-US.ftl
Adds the Claude Swap settings section, executable-path controls, account cards, usage windows, switch actions, status messages, localization, and component tests.

CLI integration

Layer / File(s) Summary
CLI all-accounts output
rust/src/cli/usage.rs
Adds Claude --all-accounts handling for text, JSON, and Toon output, with settings checks and --account conflict validation.

In `@rust/src/cli/usage.rs`:
- Line 366: Update the Claude Swap account rendering branch to check
command.brief and use the compact renderer when enabled, while retaining
render_claude_swap_text for normal output. Ensure brief mode produces one
compact line per provider.
- Line 364: Update the Claude Swap --all-accounts branches around
read_claude_swap_accounts to honor --status: fetch provider status once via the
existing fetch_provider_status flow and include it in every Text, JSON, and Toon
result, or explicitly reject --status for this mode. Keep the account status
field distinct from provider status and preserve existing output behavior when
--status is absent.

In `@rust/src/providers/claude/claude_swap.rs`:
- Line 418: Update the account-switching call in the relevant Claude swap flow
to pass a finite timeout to run_bounded instead of None, using the existing
credential-operation timeout or a separate sufficiently long timeout if needed.
Preserve the current switch_arguments(slot) invocation and error propagation.
