Release v0.5.21 — Feishu Agent channels, simpler setup, local Context · first-tree-ai/first-tree

Highlights

Connect Team Agents to Feishu through the new optional Agent Channel. The single-page OpenTag flow creates or selects an Agent, registers its bot, prepares local Feishu tooling, and supports DMs, exact group mentions, direct replies, activated threads, reactions, attachments, and bounded conversation context.
Create and manage Team Agents with a shorter flow: team-visible defaults, responsibility provenance in Profile, restored Member Workspace and Team access, clearer GitHub Task Agent eligibility, and a direct Add to Feishu handoff.
Managed Agents whose Team has no bound shared Context Tree can now use an Agent-local Context Tree fallback while valid Team bindings remain authoritative.
Cursor users can select the Router's Auto · Intelligence, Auto · Balance, and Auto · Cost modes directly in runtime settings.

macOS managed updates keep the launchd wrapper online across CLI replacement and report stopped services accurately.
Inbox acknowledgements no longer confirm deliveries outside the current socket's admitted prefix, and timeout recovery now converges safely after rebind.
Missing optional integrations degrade only the dependent operation, Grok Build 1.x is accepted, and member Workspace/Team navigation is restored.
OpenTag onboarding now completes only at a usable Feishu handoff and remains stable on narrower desktop layouts.

Existing Feishu bots must explicitly reauthorize through the visible QR flow to grant the new group-message permission; the current connection remains usable until replacement authorization succeeds.
Attachment-retention deletion remains disabled unless FIRST_TREE_ATTACHMENT_RETENTION_DELETE_ENABLED=true. When enabled, eligible message attachments older than 14 days are permanently removed unless protected by a Team Skill Resource or Agent Template bundle.
Clients older than v0.5.12 are unsupported. Deploy Web and Server from the same Docker image.
