Release Notes

v0.7.1

Release Date: March 13, 2026 Tag: v0.7.1

Chrome-Native Browser Control

v0.7.1 replaces Playwright with direct Chrome DevTools Protocol (CDP) integration. The GCU now launches the user's system Chrome via open -n on macOS, connects over CDP, and manages browser lifecycle end-to-end -- no extra browser binary required.

Highlights

System Chrome via CDP

The entire GCU browser stack has been rewritten:

  • Chrome finder & launcher -- New chrome_finder.py discovers installed Chrome and chrome_launcher.py manages process lifecycle with --remote-debugging-port
  • Coexist with user's browser -- open -n on macOS launches a separate Chrome instance so the user's tabs stay untouched
  • Dynamic viewport sizing -- Viewport auto-sizes to the available display area, suppressing Chrome warning bars
  • Orphan cleanup -- Chrome processes are killed on GCU server shutdown to prevent leaks
  • --no-startup-window -- Chrome launches headlessly by default until a page is needed

Per-Subagent Browser Isolation

Each GCU subagent gets its own Chrome user-data directory, preventing cookie/session cross-contamination:

  • Unique browser profiles injected per subagent
  • Profiles cleaned up after top-level GCU node execution
  • Tab origin and age metadata tracked per subagent

Dummy Agent Testing Framework

A comprehensive test suite for validating agent graph patterns without LLM calls:

  • 8 test modules covering echo, pipeline, branch, parallel merge, retry, feedback loop, worker, and GCU subagent patterns
  • Shared fixtures and a run_all.py runner for CI integration
  • Subagent lifecycle tests

What's New

GCU Browser

v0.7.0

Release Date: March 5, 2026 Tag: v0.7.0

Session management refactor release.

v0.5.1

Release Date: February 18, 2026 Tag: v0.5.1

The Hive Gets a Brain

v0.5.1 is our most ambitious release yet. Hive agents can now build other agents -- the new Hive Coder meta-agent writes, tests, and fixes agent packages from natural language. The runtime grows multi-graph support so one session can orchestrate multiple agents simultaneously. The TUI gets a complete overhaul with an in-app agent picker, live streaming, and seamless escalation to the Coder. And we're now provider-agnostic: Claude Code subscriptions, OpenAI-compatible endpoints, and any LiteLLM-supported model work out of the box.

Highlights

Hive Coder -- The Agent That Builds Agents

A native meta-agent that lives inside the framework at core/framework/agents/hive_coder/. Give it a natural-language specification and it produces a complete agent package -- goal definition, node prompts, edge routing, MCP tool wiring, tests, and all boilerplate files.

# Launch the Coder directly
hive code

# Or escalate from any running agent (TUI)
Ctrl+E  # or /coder in chat

The Coder ships with:

  • Reference documentation -- anti-patterns, construction guide, and design patterns baked into its system prompt
  • Guardian watchdog -- an event-driven monitor that catches agent failures and triggers automatic remediation
  • Coder Tools MCP server -- file I/O, fuzzy-match editing, git snapshots, and sandboxed shell execution (tools/coder_tools_server.py)
  • Test generation -- structural tests for forever-alive agents that don't hang on runner.run()

Multi-Graph Agent Runtime

AgentRuntime now supports loading, managing, and switching between multiple agent graphs within a single session. Six new lifecycle tools give agents (and the TUI) full control:

# Load a second agent into the runtime
await runtime.add_graph("exports/deep_research_agent")

# Tools available to agents:
# load_agent, unload_agent, start_agent, restart_agent, list_agents, get_user_presence

The Hive Coder uses multi-graph internally -- when you escalate from a worker agent, the Coder loads as a separate graph while the worker stays alive in the background.

TUI Revamp

The Terminal UI gets a ground-up rebuild with five major additions:

  • Agent Picker (Ctrl+A) -- tabbed modal screen for browsing Your Agents, Framework agents, and Examples with metadata badges (node count, tool count, session count, tags)
  • Runtime-optional startup -- TUI launches without a pre-loaded agent, showing the picker on first open
  • Live streaming pane -- dedicated RichLog widget shows LLM tokens as they arrive, replacing the old one-token-per-line display
  • PDF attachments -- /attach and /detach commands with native OS file dialog (macOS, Linux, Windows)
  • Multi-graph commands -- /graphs, /graph <id>, /load <path>, /unload <id> for managing agent graphs in-session

Provider-Agnostic LLM Support

Hive is no longer Anthropic-only. v0.5.1 adds first-class support for:

  • Claude Code subscriptions -- use_claude_code_subscription: true in ~/.hive/configuration.json reads OAuth tokens from ~/.claude/.credentials.json with automatic refresh
  • OpenAI-compatible endpoints -- api_base config routes traffic through any compatible API (Azure OpenAI, vLLM, Ollama, etc.)
  • Any LiteLLM model -- RuntimeConfig now passes api_key, api_base, and extra_kwargs through to LiteLLM

The quickstart script auto-detects Claude Code subscriptions and ZAI Code installations.

What's New

Architecture & Runtime

  • Hive Coder meta-agent -- Natural-language agent builder with reference docs, guardian watchdog, and hive code CLI command. (@TimothyZhang7)
  • Multi-graph agent sessions -- add_graph/remove_graph on AgentRuntime with 6 lifecycle tools (load_agent, unload_agent, start_agent, restart_agent, list_agents, get_user_presence). (@TimothyZhang7)
  • Claude Code subscription support -- OAuth token refresh via use_claude_code_subscription config, auto-detection in quickstart, LiteLLM header patching. (@TimothyZhang7)
  • OpenAI-compatible endpoint support -- api_base and extra_kwargs in RuntimeConfig for any OpenAI-compatible API. (@TimothyZhang7)
  • Remove deprecated node types -- Delete FlexibleGraphExecutor, WorkerNode, HybridJudge, CodeSandbox, Plan, FunctionNode, LLMNode, RouterNode. Deprecated types (llm_tool_use, llm_generate, function, router, human_input) now raise RuntimeError with migration guidance. (@TimothyZhang7)
  • Interactive credential setup -- Guided CredentialSetupSession with health checks and encrypted storage, accessible via hive setup-credentials or automatic prompting on credential errors. (@RichardTang-Aden)
  • Pre-start confirmation prompt -- Interactive prompt before agent execution allowing credential updates or abort. (@RichardTang-Aden)
  • Event bus multi-graph support -- graph_id on events, filter_graph on subscriptions, ESCALATION_REQUESTED event type, exclude_own_graph filter. (@TimothyZhang7)

TUI Improvements

  • In-app agent picker (Ctrl+A) -- Tabbed modal for browsing agents with metadata badges (nodes, tools, sessions, tags). (@TimothyZhang7)
  • Runtime-optional TUI startup -- Launches without a pre-loaded agent, shows agent picker on startup. (@TimothyZhang7)
  • Hive Coder escalation (Ctrl+E) -- Escalate to Hive Coder and return; also available via /coder and /back chat commands. (@TimothyZhang7)
  • PDF attachment support -- /attach and /detach commands with native OS file dialog. (@TimothyZhang7)
  • Streaming output pane -- Dedicated RichLog widget for live LLM token streaming. (@TimothyZhang7)
  • Multi-graph TUI commands -- /graphs, /graph <id>, /load <path>, /unload <id>. (@TimothyZhang7)
  • Agent Guardian watchdog -- Event-driven monitor that catches secondary agent failures and triggers automatic remediation, with --no-guardian CLI flag. (@TimothyZhang7)

New Tool Integrations

  • System prompt datetime injection -- All system prompts now include current date/time for time-aware agent behavior. (@TimothyZhang7)
  • Utils module exports -- Proper __init__.py exports for the utils module. (@Siddharth2624)
  • Increased default max_tokens -- Opus 4.6 defaults to 32768, Sonnet 4.5 to 16384 (up from 8192). (@TimothyZhang7)

Bug Fixes

  • Flush WIP accumulator outputs on cancel/failure so edge conditions see correct values on resume
  • Stall detection state preserved across resume (no more resets on checkpoint restore)
  • Skip client-facing blocking for event-triggered executions (timer/webhook)
  • Executor retry override scoped to actual EventLoopNode instances only
  • Add _awaiting_input flag to EventLoopNode to prevent input injection race conditions
  • Fix TUI streaming display (tokens no longer appear one-per-line)
  • Fix _return_from_escalation crash when ChatRepl widgets not yet mounted
  • Fix tools registration problems for Google Docs credentials (@RichardTang-Aden)
  • Fix email agent version conflicts (@RichardTang-Aden)

Documentation

  • Clarify installation and prevent root pip install misuse (@paarths-collab)

Agent Updates

  • Email Inbox Management -- Consolidate gmail_inbox_guardian and inbox_management into a single unified agent with updated prompts and config. (@RichardTang-Aden, @bryanadenhq)
  • Job Hunter -- Updated node prompts, config, and agent metadata; added PDF resume selection. (@bryanadenhq)
  • Deep Research Agent -- Revised node implementations with updated prompts and output handling.
  • Tech News Reporter -- Revised node prompts for improved output quality.
  • Vulnerability Assessment -- Expanded prompts with more detailed assessment instructions. (@bryanadenhq)

Breaking Changes

  • Deprecated node types raise RuntimeError -- llm_tool_use, llm_generate, function, router, human_input now fail instead of warning. Migrate to event_loop.
  • NodeSpec.node_type defaults to "event_loop" (was "llm_tool_use")
  • NodeSpec.max_node_visits defaults to 0 / unlimited (was 1)
  • NodeSpec.function field removed -- FunctionNode is deleted; use event_loop nodes with tools instead.

Migration Guide

If your agents use deprecated node types, update them:

# Before (v0.5.0) -- these now raise RuntimeError
NodeSpec(node_type="llm_tool_use", ...)
NodeSpec(node_type="function", function=my_func, ...)

# After (v0.5.1) -- use event_loop for everything
NodeSpec(node_type="event_loop", ...)  # or just omit node_type (it's the default now)

If your agents set max_node_visits=1 explicitly, they'll still work. The only change is the default -- new agents without an explicit value now get unlimited visits.

To try the new Hive Coder:

# Launch Coder directly
hive code

# Or from TUI -- press Ctrl+E to escalate
