See the [A2A protocol reference](/docs/api-protocol/communication-rules) for the full endpoint list. + +--- + +## Production upgrade path + +The quickstart leaves you with an ephemeral demo. For real use: + +1. **Deploy to a real host**: Fly Machine / Railway / anywhere with a stable URL + TLS. +2. **Use a named Cloudflare tunnel**: survives restarts, gets you a consistent subdomain. +3. **Authenticate outbound calls correctly**: store the `workspace_auth_token` (returned when you register via `/registry/register`; see the [full registration doc](/docs/guides/external-agent-registration)) and send it as `Authorization: Bearer ...` on every outbound call to the tenant. +4. **Add an LLM**: swap the echo handler for `anthropic` / `openai` / `ollama` / your model of choice. +5. **Handle long-running work**: use the (upcoming) polling mode transport so you don't need a publicly reachable URL at all. + +--- + +## Next step: polling mode (preview) + +Push mode (this guide) works today but requires an inbound-reachable URL β€” which forces tunnels or public IPs. A polling-mode transport is in design: + +``` +[Canvas] --A2A--> [Platform] <--polls-- [Your laptop] + [inbox queue] -->replies +``` + +Your agent makes only outbound HTTPS calls to the platform, pulling messages from an inbox queue and posting replies back.

Phase 2 (priority inversion deadlock prevention) on the roadmap. + +#### πŸ”§ Fixes + +- **A2A queue nil-safe drain** (`molecule-core` [#1893](https://github.com/Molecule-AI/molecule-core/pull/1893), [#1896](https://github.com/Molecule-AI/molecule-core/pull/1896)): `DequeueTask` no longer panics when the in-memory queue map is uninitialized β€” graceful empty-result returned instead. +- **Workspaces stuck in `provisioning` afterε€±θ΄₯** (`molecule-core` [#1794](https://github.com/Molecule-AI/molecule-core/pull/1794)): provisioner now transitions workspaces to `failed` state with a descriptive error message instead of leaving them orphaned in `provisioning`. +- **Dedup settings hooks double-fire** (`molecule-core` [#1797](https://github.com/Molecule-AI/molecule-core/pull/1797)): the `dedup_settings_hooks` registry now correctly unsubscribes after one fire β€” eliminates the 3–4Γ— duplicate hook execution observed in CI. +- **Semantic memory search returning stale results** (`molecule-core` [#1778](https://github.com/Molecule-AI/molecule-core/pull/1778)): pgvector index now refreshes synchronously on `commit_memory` write instead of on a 5-minute background cycle. +- **pgvector migration race in E2E CI** (`molecule-core` [#1777](https://github.com/Molecule-AI/molecule-core/pull/1777)): `CREATE EXTENSION` wrapped in `IF NOT EXISTS` inside a `DO` block β€” eliminates E2E CI flakiness on fresh DB spin-up. +- **EC2 Instance Connect endpoint not found in us-west-2** (`molecule-core` [#1779](https://github.com/Molecule-AI/molecule-core/pull/1779)): Instance Connect endpoint SDK call now falls back gracefully to direct SSM session when the EIC endpoint is unavailable in a region. +- **Canvas topology overlay edge labels clipped** (`molecule-core` [#1802](https://github.com/Molecule-AI/molecule-core/pull/1802)): SVG edge labels now respect viewport bounds; labels that would render off-screen are repositioned. +- **Audit trail panel not loading for large workspaces** (`molecule-core` [#1854](https://github.com/Molecule-AI/molecule-core/pull/1854)): audit log fetch now uses cursor-based pagination (100 events per page) instead of returning all events at once. +- **Hermes `response_format` not forwarded to MiniMax** (`molecule-core` [#1861](https://github.com/Molecule-AI/molecule-core/pull/1861)): `response_format=json_schema` now propagates through the model config passthrough for hermes/MiniMax-M2.7-highspeed workspaces. +- **Memory Inspector panel memory leak** (`molecule-core` [#1871](https://github.com/Molecule-AI/molecule-core/pull/1871)): `useMemoryStore` hook now correctly cancels the SSE subscription on panel unmount. +- **Token revocation cache stale-read window** (`molecule-core` [#1888](https://github.com/Molecule-AI/molecule-core/pull/1888)): revoked-token invalidation now propagates within 5 s (down from 60 s) β€” closes the window where a revoked token could still authenticate. +- **TenantGuard same-origin bypass (regression)** (`molecule-core` [#1898](https://github.com/Molecule-AI/molecule-core/pull/1898)): fixes a regression introduced in the Phase 33 cloudflare-removal change that re-opened the TenantGuard same-origin bypass for EC2 tenant Canvas deployments. + +#### πŸ“š Docs + +- **Chrome DevTools MCP tutorial** (`docs` [#1798](https://github.com/Molecule-AI/docs/pull/1798)): hands-on guide for debugging Molecule AI agents in-browser using Chrome's built-in MCP inspector. +- **Phase 34 launch page** (`docs` [#1799](https://github.com/Molecule-AI/docs/pull/1799)): public-facing launch collateral for GA scheduled 2026-04-30. +- **Tool Trace demo environment** (`docs` [#1844](https://github.com/Molecule-AI/docs/pull/1844)): interactive demo showing the tool trace inspector in action, with sample run data. +- **Enterprise battlecard** (`docs` [#1864](https://github.com/Molecule-AI/docs/pull/1864)): competitive positioning doc for sales and enterprise evaluation teams. + +#### 🧹 Internal + +- `a2a-sdk` hot-pinned to `0.3.x` across all workspace template repos (`molecule-core` [#1890](https://github.com/Molecule-AI/molecule-core/pull/1890)); SDK upgrade path documented in `KI-009` (`internal` [#1631](https://github.com/Molecule-AI/internal/issues/1631)). +- Phase 34 CI matrix expanded to cover Node 22 and Go 1.24 (`molecule-ci`). + +#### πŸ”§ Runtime fixes + +- **Heartbeat 401 retry** (`molecule-ai-workspace-runtime` [#40](https://github.com/Molecule-AI/molecule-ai-workspace-runtime/pull/40)): heartbeat worker now retries with fresh token on 401 before declaring the workspace unreachable β€” eliminates false `disconnected` status during token rotation. +- **LLM token auto-detect** (`molecule-ai-workspace-runtime` [#38](https://github.com/Molecule-AI/molecule-ai-workspace-runtime/pull/38)): hermes runtime now auto-detects `max_tokens` from model context window and request timeout when not explicitly configured. + --- From 30fc34744089d896c42a96caad546377ac5c88a7 Mon Sep 17 00:00:00 2001 From: Hongming Wang Date: Thu, 23 Apr 2026 22:20:01 -0700 Subject: [PATCH 5/5] ci: route build to self-hosted Mac mini runner MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit docs is a private repo and the org's GitHub-hosted Actions minute budget is exhausted. Every ubuntu-latest run on this repo has been dying in ~2s with zero step output (runner allocated then killed before checkout). Per the 2026-04-22 runner policy: private repos use the self-hosted Mac mini; public repos stay on ubuntu-latest (which remains free for public repos regardless of minute budget). Switches `runs-on: ubuntu-latest` β†’ `runs-on: self-hosted`. No other changes. The existing steps (checkout, node 20 setup, npm ci, npm run build) all work on macOS without modification. If the Mac mini has more specific labels assigned (e.g. macOS, ARM64), tighten this to a matrix later β€” for now `self-hosted` matches any registered runner, which should route correctly as long as there's only one in the org. --- .github/workflows/ci.yml | 7 ++++++- 1 file changed, 6 insertions(+), 1 deletion(-) diff --git a/.github/workflows/ci.yml b/.github/workflows/ci.yml index 4643d3c..5fd37cd 100644 --- a/.github/workflows/ci.yml +++ b/.github/workflows/ci.yml @@ -6,7 +6,12 @@ on: branches: [main] jobs: build: - runs-on: ubuntu-latest + # Self-hosted Mac mini β€” this repo is private and the org's + # GitHub-hosted minute budget is exhausted (every ubuntu-latest job + # dies in 2s with no step output).
