הורדת DingTalk Workspace CLI 1.0.17

Highlights
New Mail product surface (mailbox list, KQL message search, message get, send) brings runtime command count to 163 across 14 products. Plugin command-tree visibility hardening: stdio plugins shipping CLI overlays no longer wait on subprocess discovery to surface their commands, and overlay-registered plugin products are no longer hidden by edition VisibleProducts whitelists. Chat docs clarify that --title is required on dws chat message send.
Added
- mail product (#167) — new top-level service for DingTalk Mail. Four leaf commands across two subgroups:
- dws mail mailbox list — list mailbox addresses available to the current user (list_user_mailboxes)
- dws mail message search — KQL search across folders / sender / date / attachments / read-state (search_emails); supports --cursor pagination
- dws mail message get — fetch full message body + headers + attachments by message ID (get_email_by_message_id)
- dws mail message send — send email to one or more recipients (send_email)
- Skill reference at skills/references/products/mail.md registered in skills/SKILL.md master index and intent decision tree
- Stdio plugin overlay-first command registration (#179) — when a stdio plugin's overlay.json declares toolOverrides, command trees are built from manifest metadata synchronously at startup, no subprocess Initialize / tools/list handshake required. Previously, slow or failing subprocesses left plugin commands invisible in dws --help. Background discovery still runs to refresh the warm cache for richer flag types on subsequent startups.
Changed
- hideNonDirectRuntimeCommands / visibleMCPRootCommands / visibleUtilityRootCommands (#179) — refactored to share a single resolveVisibleProducts() helper that unions the edition's VisibleProducts hook with DirectRuntimeProductIDs(), so plugins registered via AppendDynamicServer stay visible in dws --help even when an edition installs a static product whitelist. Previously the hook fully replaced the dynamic registry, silently hiding plugin commands.
- dws chat message send documentation clarifies --title is required (#174) — the helper command short text and the chat skill reference now state explicitly that --title is mandatory for both group and single-chat sends, matching the runtime validation.
- buildStdioCommands refactored to share helpers with the overlay-first path (#179) — overlay parsing (resolveStdioOverlay) and tools→DetailTool conversion (toolsToDetails) extracted as package-level helpers; the legacy discovery-first stdio path now delegates to them, eliminating duplicated overlay JSON / cache-snapshot logic.
Fixed
- Negative-cache poisoning guard for stdio plugin discovery (#179) — refreshStdioToolsCache now skips SaveTools entirely when discovery returns an empty tool list (transient failure, subprocess not ready, RPC timeout), so a single bad refresh cannot overwrite a previously-good cache and degrade flag enrichment on the next startup.
Tests
- 6 new test cases in internal/app/plugin_stdio_overlay_test.go and internal/app/visibility_test.go cover overlay-first registration without discovery, warm-cache flag enrichment from InputSchema, fallback when overlays lack toolOverrides, the cache-poisoning guard, and integration cases for plugin visibility under restrictive VisibleProducts whitelists.
- Coverage 49.8% → 52.8%.
