+# Phase 34 Community Announcement
+**Campaign:** Phase 34 GA (April 30, 2026)
+**Owner:** Community Manager
+**Issue:** [Molecule-AI/molecule-core#1836](https://github.com/Molecule-AI/molecule-core/issues/1836)
+**Status:** ✅ Draft complete — review before publish
+
+---
+
+```
+🚀 Phase 34 shipped!
+
+Four features dropped today that make Molecule AI meaningfully better for
+teams running agents in production. Let's dig in.
+
+━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
+
+What's new
+
+🔍 Tool Trace — see exactly what your agent did
+──────────────────────────────────────────────
+Every A2A response now includes a tool_trace[] array in the response
+metadata. For each tool call, you get: tool name, input params, output
+preview — in order, with run_id pairing for parallel calls.
+
+If you've ever spent an hour reverse-engineering an agent's behavior from
+final outputs, you'll understand why this matters. Tool Trace is in every
+response. No SDK, no sidecar, no sampling.
+
+Enable activity logging on your workspace and every task gets a full
+execution record, stored in activity_logs.
+
+Docs: docs/architecture/activity-logs.md
+PR: #1686 (merged 2026-04-23)
+
+
+📋 Platform Instructions — governance before the agent runs
+──────────────────────────────────────────────
+Org admins can now configure system-level instructions via API:
+POST /cp/platform-instructions
+
+Think of it as a system prompt for your entire org. You can inject shared
+context, enforce behavioral rules, or set compliance guardrails — and they
+take effect at workspace startup, before the agent reads its own config.
+
+"Never commit to main without a review."
+"Tag all security-sensitive operations."
+"Don't write outside the project directory."
+
+These rules prepend to every agent's effective system prompt in your org,
+regardless of individual workspace config. Governance happens before
+execution, not after an incident.
+
+Docs: docs/architecture/platform-instructions.md
+
+
+🔑 Partner API Keys (GA April 30)
+──────────────────────────────────────────────
+Programmatic org provisioning via API — no browser, no manual handoff.
+
+CI/CD pipelines, marketplace integrations, platform builders: you can now
+create and manage Molecule AI orgs entirely via API using scoped,
+revocable tokens with the mol_pk_* prefix.
+
+Common pattern: ephemeral test orgs per PR.
+  POST /cp/orgs → run your test suite → DELETE → billing stops.
+
+Default rate limit: 60 req/min per key (configurable). Keys are scoped,
+irreversibly revocable, and logged in the audit trail.
+
+This is, to our knowledge, the first partner provisioning API of its kind
+in the agent platform space.
+
+Docs: docs/architecture/partner-api-keys.md
+GA: April 30, 2026
+
+
+☁️ SaaS Federation v2
+──────────────────────────────────────────────
+Federation improvements for multi-org deployments: better cross-tenant
+isolation, improved org lifecycle management, and tighter alignment with
+the Partner API Keys infrastructure.
+
+If you're running multiple orgs — for partners, for internal teams, or
+for different products — the improvements to federation architecture make
+it more robust to operate at scale.
+
+Docs: docs/architecture/saas-federation.md (or link to relevant docs)
+
+
+━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
+
+Quick start
+
+Tool Trace is live now — enabled by default for all workspaces.
+Check your A2A responses for message.metadata.tool_trace[].
+
+Platform Instructions: POST /cp/platform-instructions (org admin only)
+Docs: docs/architecture/platform-instructions.md
+
+Partner API Keys: GA April 30 — apply for early access via GitHub
+Discussions if you want to test ahead of the release.
+
+SaaS Fed v2: active for all SaaS tenants, no action needed.
