Pre-release

Re-tagged — finishes the rubyn-code token-saving port (#312 AutoCompact + Compactor + prompt-too-long recovery, #313 ContextBudget, #314 #compact hashtag, #315 ModelRouter auto-selection).

Fixes

#311 1h cache TTL + claude-code-20250219 beta (openclaw parity)
#310 task_manager move 422 — added transition_requested + pipeline_failed to TaskEvent enum
#308 Stay within Anthropic's 4 cache_control marker limit — rubyn/openclaw parity (OAuth uses all 4 markers, non-OAuth 3)
#307 Surface Agents::ToolLoop failures in ChatStreamJob instead of silently swallowing them

Features — rubyn-code token-saving port (finishes the #282 foundation)

#315 Agents::ModelRouter — auto-tier routing for Anthropic + OpenAI. Set an agent's model to auto and each chat turn picks cheap/mid/top based on keyword + recent-tool heuristics. Runtime-tunable via the model_router_rules Setting (JSON). Ollama + openai_compatible stay manual-only.
#314 #compact hashtag — user-triggered session compaction. Replaces the transcript with an LLM-generated continuity summary; preserves last 3 originals in session.metadata for recovery.
#313 Agents::ContextBudget — priority-based related-file loader for file_read. Loads primary + related files (spec first, then factory/service/model/…) up to 4k tokens; over-budget files fall back to signature-only extraction. Opt-in per call via load_related: true.
#312 Agents::AutoCompact + Compactor + prompt-too-long recovery — over-budget context gets summarized by Claude Haiku into a continuity message instead of hard-truncated. Over-context API errors trigger an auto-compact + retry automatically.
#309 Prompt-debug + SDK-proxy toggle on the Anthropic provider edit page
#282 Direct-API Anthropic agent loop with prompt caching + token-saving pipeline
#305 True sleep tool for agents
#301 Task hook 3-phase pipeline (Pre → Transition → Post)
#299 Browser sidecar — Python FastAPI with full interaction primitives
#294 Task ↔ Milestone linking
#306 Close task hook sessions on completion
#304 Remove hard 50-task limit from task_manager
#300 Prioritize task assignee over transitioning agent in hook dispatch
#291 Eliminate N+1 queries in SwarmExporter / AgentSerializer

Swarms (import/export/validation)

#293 Full round-trip integration test suite
#292 Workspace files, scheduled tasks & heartbeat config import/export (Task #209)
#289 Egress policy, tool loop config & budget limits import/export (Task #210)
#288 Channels, MCP servers & API integrations import/export (Task #208)

⚡ Highlights

This release introduces three major systems — Lightweight Task Layer, Agent Hierarchy, and Event-Driven Hooks — alongside a complete Heartbeat architecture overhaul and a redesigned Chat UI. Together, these turn Hivemind from a chat-with-agents platform into a full agent orchestration system where agents can own work, report up, and trigger each other automatically.

🔧 Hotfix

fix: resolve hook agent from task assignee, not transition triggerer — Task hooks now correctly route work to whoever is assigned to the task, not whoever triggered the status change.

🆕 Features

Lightweight Task Layer

A full-featured task board for agents and humans alike. Create, assign, move, and track tasks with checklists, dependencies, and artifacts — all wired into the agent tool system.

feat: Lightweight Task Layer (Milestone 10) by @MatthewSuttles in #224
feat: complete lightweight task layer — associations, #todo parsing, agent context by @MatthewSuttles in #248
feat: Lightweight Task Layer — project/milestone linkage, enhanced #todo parsing, agent task context by @MatthewSuttles in #246
feat: add archive button for done tasks (#24) by @MatthewSuttles in #255

Agent Hierarchy & Org Chart

Agents now have managers and direct reports. The org chart renders on the team edit page, giving you a visual map of your agent organization.

feat: render org chart on team edit page by @MatthewSuttles in #241
feat: agent activity audit log view (Task #37) by @MatthewSuttles in #243

Event-Driven Hook System

Tasks can now trigger agent actions automatically when they change status. Create pipelines where completing one task kicks off the next — with dedicated management UI and auto-assignment.

feat: event-driven task execution via hook system by @MatthewSuttles in #260
feat: task hook triggers by @MatthewSuttles in #261 / #262
feat: dedicated hooks management page + task artifacts by @MatthewSuttles in #263
feat: hook agent auto-assign for pipeline handoffs by @MatthewSuttles in #264

Heartbeat Architecture Overhaul

The heartbeat system was rebuilt from the ground up — three-tier monitor/delegator architecture, ephemeral sessions with relay summaries, standing task UI, and tighter scoping so the heartbeat agent stays focused.

feat: heartbeat architecture overhaul — three-tier monitor/delegator system by @MatthewSuttles in #242
feat: ephemeral heartbeat sessions with relay summaries by @MatthewSuttles in #254
feat: add standing task creation UI to heartbeat page by @MatthewSuttles in #244
Restrict heartbeat to task_manager by @MatthewSuttles in #259
Disable Projects::Coordinator in heartbeat loop by @MatthewSuttles in #258

Chat UI Redesign

Compact agent cards, a session list with filters, and a proper 1:1 chat sidebar. The whole chat experience got a facelift.

feat: chat UI redesign — compact cards, session list with filters, and 1:1 chat sidebar by @MatthewSuttles in #265

Browser Sidecar

Replaced the heavy Playwright container with a lightweight native HTTP sidecar for browser-based tools. Faster, simpler, less resource-hungry.

feat: Browser Sidecar — replace Playwright container with native HTTP sidecar by @MatthewSuttles in #240

Other Features

feat: wire ToolLoop into Sessions::Chat for all providers by @MatthewSuttles in #257
feat: mobile markdown rendering by @MatthewSuttles
