Behind feature flag DELEGATION_SYNC_VIA_INBOX (default off). When set,
tool_delegate_task no longer holds an HTTP message/send connection
through the platform proxy waiting for the callee's reply. Instead:
1. POST /workspaces/<src>/delegate (returns 202 + delegation_id)
— platform's executeDelegation goroutine handles A2A dispatch
in the background. No client-side timeout dependency on the
platform holding a connection open.
2. Poll GET /workspaces/<src>/delegations every 3s for a row with
matching delegation_id reaching terminal status (completed/failed).
3. Return the response_preview text on completed; surface the
wrapped _A2A_ERROR_PREFIX error on failed (so caller error
detection stays unchanged).
This closes the bug class that broke Hongming's home hermes on
2026-05-05 ("message/send queued but result not available after 600s
timeout" while the callee was actively heartbeating "iteration 14/90").
## Compatibility
Default-off feature flag — flag-off path is byte-identical to the
legacy send_a2a_message behavior, pinned by
TestFlagOffLegacyPath::test_flag_off_uses_send_a2a_message_not_polling.
Idempotency-key derivation matches tool_delegate_task_async (SHA-256
of source:target:task) so a restart-mid-delegation gets the same key
and the platform returns the existing delegation_id.
## Recovery on timeout
If the polling budget (DELEGATION_TIMEOUT, default 300s) elapses
without a terminal status, the error message includes the
delegation_id + a "call check_task_status('<id>') to retrieve later"
hint. The platform's durable row is still live — work is NOT lost,
just the synchronous wait is over. Caller can poll for the result
later via the existing check_task_status tool.
## Stack with PR-2
PR-2 added the SERVER-SIDE result-push to the caller's a2a_receive
inbox row. PR-5 (this PR) adds the AGENT-SIDE cutover. Together they
remove the proxy-blocked sync path entirely. PR-2 default-off keeps
existing behavior; PR-5 default-off keeps existing behavior. Operators
flip both for full effect after staging burn-in.
## Coverage
9 unit tests:
- flag off → byte-identical to legacy (send_a2a_message called,
_delegate_sync_via_polling NOT called)
- dispatch HTTP exception → wrapped error
- dispatch non-2xx → wrapped error mentioning HTTP code
- dispatch missing delegation_id → wrapped error
- completed first poll → response_preview returned
- failed status → wrapped error with error_detail
- transient poll error → keeps polling, eventually succeeds
- deadline exceeded → wrapped timeout error mentions delegation_id +
check_task_status hint for recovery
- filters by delegation_id (other delegations' rows ignored)
All passing locally. CI will run the same suite on a clean env.

The Org-Native Control Plane For Heterogeneous AI Agent Teams
The world's most powerful governance platform for AI agent teams.
Visual Canvas • Runtime Compatibility • Hierarchical Memory • Skill Evolution • Operational Guardrails
Docs Home • Quick Start • Architecture • Platform API • Workspace Runtime
The Pitch
Molecule AI is the most powerful way to govern an AI agent organization in production.
It combines the parts that are usually scattered across demos, internal glue code, and framework-specific tooling into one product:
- one org-native control plane for teams, roles, hierarchy, and lifecycle
- one runtime layer that lets LangGraph, DeepAgents, Claude Code, CrewAI, AutoGen, and OpenClaw run side by side
- one memory model that keeps recall, sharing, and skill evolution aligned with organizational boundaries
- one operational surface for observing, pausing, restarting, inspecting, and improving live workspaces
Most teams can build a workflow, a strong single agent, a coding agent, or a custom multi-agent graph.
Very few teams can run all of that as a governed organization with clear structure, durable memory boundaries, and production operations.
That is the gap Molecule AI closes.
Why Molecule AI Feels Different
1. The node is a role, not a task
In Molecule AI, a workspace is an organizational role. That role can begin as one agent, later expand into a sub-team, and still keep the same external identity, hierarchy position, memory boundary, and A2A interface.
2. The org chart is the topology
You do not wire collaboration paths by hand. Hierarchy defines the default communication surface. The structure is not decorative UI. It is part of the operating model.
3. Runtime choice stops being a dead-end decision
LangGraph, DeepAgents, Claude Code, CrewAI, AutoGen, and OpenClaw can all plug into the same workspace abstraction. Teams can standardize governance without forcing every group onto one runtime.
4. Memory is treated like infrastructure
Molecule AI's HMA approach is designed around organizational boundaries, not just “store more context somewhere.” Durable recall, scoped sharing, awareness namespaces, and skill promotion are all part of one coherent system.
5. It comes with a real control plane
Registry, heartbeats, restart, pause/resume, activity logs, approvals, terminal access, files, traces, bundles, templates, and WebSocket fanout are not afterthoughts. They are first-class parts of the platform.
The Category Gap Molecule AI Fills
| Category | What it does well | Where it breaks | What Molecule AI adds |
|---|---|---|---|
| Workflow builders | Visual task automation | Nodes are tasks, not durable organizational roles | Role-native workspaces, hierarchy, long-lived teams |
| Agent frameworks | Strong runtime semantics | Weak control plane and weak org-level operations | Unified lifecycle, canvas, registry, policies, observability |
| Coding agents | Excellent local execution | Usually not designed as team infrastructure | Workspace abstraction, A2A collaboration, platform ops |
| Custom multi-agent graphs | Full flexibility | Brittle topology and governance sprawl | Standardized operating model without losing runtime freedom |
What Makes Molecule AI Defensible
| Advantage | Why it matters in practice |
|---|---|
| Role-native workspace abstraction | Your org structure survives model swaps, framework changes, and team expansion |
| Fractal team expansion | A single specialist can become a managed department without breaking upstream integrations |
| Heterogeneous runtime compatibility | Different teams can keep their preferred agent architecture while sharing one control plane |
| HMA + awareness namespaces | Memory sharing follows hierarchy instead of leaking across the whole system |
| Skill evolution loop | Durable successful workflows can graduate from memory into reusable, hot-reloadable skills |
| WebSocket-first operational UX | The canvas reflects task state, structure changes, and A2A responses in near real time |
| Global secrets with local override | Centralize provider access, then override only where a workspace needs specialized credentials |
Runtime Compatibility, Compared
Molecule AI is not trying to replace the frameworks below. It is the system that makes them easier to run together.
| Runtime / architecture | Status in current repo | Native strength | What Molecule AI adds |
|---|---|---|---|
| LangGraph | Shipping on main |
Graph control, tool use, Python extensibility | Canvas orchestration, hierarchy routing, A2A, memory scopes, operational lifecycle |
| DeepAgents | Shipping on main |
Deeper planning and decomposition | Same workspace contract, team topology, activity stream, restart behavior |
| Claude Code | Shipping on main |
Real coding workflows, CLI-native continuity | Secure workspace abstraction, A2A delegation, org boundaries, shared control plane |
| CrewAI | Shipping on main |
Role-based crews | Persistent workspace identity, policy consistency, shared canvas and registry |
| AutoGen | Shipping on main |
Assistant/tool orchestration | Standardized deployment, hierarchy-aware collaboration, shared ops plane |
| OpenClaw | Shipping on main |
CLI-native runtime with its own session model | Workspace lifecycle, templates, activity logs, topology-aware collaboration |
| NemoClaw | WIP on feat/nemoclaw-t4-docker |
NVIDIA-oriented runtime path | Planned to join the same abstraction once merged; not yet part of main |
This is the key idea: many agent runtimes, one organizational operating system.
Why The Memory Architecture Compounds
Most projects stop at “we added memory.” Molecule AI pushes further:
| Conventional memory setup | Molecule AI |
|---|---|
| Flat store or weak namespaces | Hierarchy-aligned LOCAL, TEAM, GLOBAL scopes |
| Sharing is easy to overexpose | Sharing is explicit and structure-aware |
| Memory and procedure get mixed together | Memory stores durable facts; skills store repeatable procedure |
| Every agent can become over-privileged | Workspace awareness namespaces reduce blast radius |
| UI memory and runtime memory blur together | Separate surfaces for scoped agent memory, key/value workspace memory, and recall |
The flywheel
Task execution
-> durable insight captured in memory
-> repeated success becomes a signal
-> workflow promoted into a reusable skill
-> skill hot-reloads into the runtime
-> future work gets faster and more reliable
This is one of Molecule AI's strongest long-term advantages: the system can get more operationally capable without turning into one giant hidden prompt.
Self-Improving Agent Teams, Built Into Molecule AI
Most agent systems stop at "a smart runtime." Molecule AI pushes further: it gives teams a way to capture what worked, promote repeatable procedure into skills, reload those improvements into live workspaces, and keep the whole loop visible at the platform level.
| Positioning lens | Conventional self-improving agent pattern | Molecule AI |
|---|---|---|
| Unit of improvement | A single agent session or runtime | A workspace, a team, and eventually the whole org graph |
| Operational surface | Mostly hidden inside the agent loop | Visible in the platform, Canvas, activity stream, memory surfaces, and runtime controls |
| Strategic outcome | A smarter agent | A compounding organization with durable knowledge and governed reusable skills |
Where that shows up in Molecule AI
| Core mechanism | Molecule AI module(s) | Why it matters |
|---|---|---|
| Durable memory that survives sessions | workspace/builtin_tools/memory.py, workspace/builtin_tools/awareness_client.py, workspace-server/internal/handlers/memories.go |
Memory is not just durable, it is workspace-scoped and can route into awareness namespaces tied to the org structure |
| Cross-session recall | workspace-server/internal/handlers/activity.go (/workspaces/:id/session-search) |
Recall spans both activity history and memory rows, so the system can search what happened and what was learned without inventing a separate hidden store |
| Skills built from experience | workspace/builtin_tools/memory.py (_maybe_log_skill_promotion) |
Promotion from memory into a skill candidate is surfaced as an explicit platform activity, not a silent internal side effect |
| Skill improvement during use | workspace/skill_loader/watcher.py, workspace/skill_loader/loader.py, workspace/main.py |
Skills hot-reload into the live runtime, so improvements become available on the next A2A task without restarting the workspace |
| Persistent skill lifecycle | workspace-server/cmd/cli/cmd_agent_skill.go, workspace/plugins.py |
Skills are not just generated once; they can be audited, installed, published, shared, mounted by plugins, and governed as reusable operational assets |
Why this matters in Molecule AI
-
The learning loop is org-aware, not just session-aware. Memory can live at
LOCAL,TEAM, orGLOBALscope, and awareness namespaces give each workspace a durable identity boundary. -
The learning loop is visible to operators. Promotion events, activity logs, current-task updates, traces, and WebSocket fanout mean self-improvement is part of the control plane, not a hidden black box.
-
The learning loop compounds across teams, not just one agent. A workflow learned by one workspace can become a governed skill, reload into the runtime, appear in the Agent Card, and become usable inside a larger organizational hierarchy.
The result is not just “an agent that learns.” It is an organization that gets more capable as its workspaces accumulate durable memory and reusable procedure.

Quick Start
git clone https://github.com/Molecule-AI/molecule-monorepo.git
cd molecule-monorepo
cp .env.example .env
# Defaults boot the stack locally out of the box. See .env.example for
# production hardening knobs (ADMIN_TOKEN, SECRETS_ENCRYPTION_KEY, etc.).
./infra/scripts/setup.sh
# Boots Postgres (:5432), Redis (:6379), Langfuse (:3001),
# and Temporal (:7233 gRPC, :8233 UI) on the shared
# `molecule-monorepo-net` Docker network. Temporal runs with
# no auth on localhost — dev-only; production must gate it.
#
# Also populates the template/plugin registry by cloning every repo
# listed in manifest.json into workspace-configs-templates/,
# org-templates/, and plugins/. Requires jq — install via
# `brew install jq` (macOS) or `apt install jq` (Debian). Idempotent:
# re-runs skip any target dir that's already populated.
cd workspace-server
go run ./cmd/server # applies pending migrations on first boot
cd ../canvas
npm install
npm run dev
Then open http://localhost:3000:
- Deploy a template or create a blank workspace from the empty state.
- Follow the onboarding guide into
Config. - Add a provider key in
Secrets & API Keys. - Open
Chatand send the first task.
