Fourth slice of the a2a_tools.py split (stacked on iter 4c). Owns the
four human-and-peer messaging MCP tools + the chat-upload helper:
* _upload_chat_files — stage local paths to /chat/uploads
* tool_send_message_to_user — push canvas-chat via /notify
* tool_list_peers — discover peers across registered workspaces
* tool_get_workspace_info — JSON-encode workspace info
* tool_chat_history — fetch prior conversation rows with a peer
a2a_tools.py shrinks from 508 → 213 LOC (−295). The remaining 213
is just report_activity + back-compat re-exports. Inbox tools
(tool_inbox_peek/pop/wait_for_message) deferred to iter 4e.
Layered architecture: messaging depends on a2a_tools_rbac (iter 4a),
a2a_client, platform_auth — NOT on kitchen-sink a2a_tools. An
import-contract test pins this so future refactors that add
`from a2a_tools import …` fail in CI.
Tests:
* 28 patch sites in TestToolSendMessageToUser + TestToolListPeers +
TestToolGetWorkspaceInfo + TestChatHistory retargeted from
`a2a_tools.{httpx, get_peers_*, get_workspace_info,
_upload_chat_files, _peer_*, list_registered_workspaces}` to
`a2a_tools_messaging.…` because the call sites moved.
* test_a2a_tools_messaging.py adds 7 new tests:
- 5 alias drift gates
- 2 import-contract tests (no top-level a2a_tools dep + a2a_tools
surfaces every messaging symbol)
137 tests total in the a2a_tools suite, all green.

RFC #2251 coordinator task-bound harnesses
There are three related scripts; pick the right one:
| Script | Purpose | Targets |
|---|---|---|
measure-coordinator-task-bounds.sh |
Canonical v1 harness for the RFC #2251 / Issue 4 reproduction. Provisions a PM coordinator + Researcher child via claude-code-default + langgraph templates, sends a synthesis-heavy A2A kickoff, observes elapsed time + activity trace. |
OSS-shape platform — localhost or any /workspaces-shaped endpoint. Has tenant/admin-token guards for non-localhost runs. |
measure-coordinator-task-bounds-runner.sh |
Generalised runner for the same measurement contract but with arbitrary template + secret + model combinations (Hermes/MiniMax, etc.). Useful for cross-runtime variants without modifying the canonical harness. | Same as above (local or SaaS via MODE=saas). |
measure-coordinator-task-bounds.sh (in molecule-controlplane) |
Production-shape variant that bootstraps a real staging tenant via POST /cp/admin/orgs, then runs the same measurement against <slug>.staging.moleculesai.app. |
Staging controlplane only — refuses to run against production. |
See reference_harness_pair_pattern (auto-memory) for when to use which
and the cross-repo design rationale.
Common safety pattern across all three
- Cleanup trap on EXIT/INT/TERM auto-deletes provisioned resources.
DRY_RUN=1prints plan + auth fingerprint, exits before any state mutation. Run this before pointing at staging or any shared infrastructure.- Non-target guard refuses arbitrary endpoints (the controlplane
variant is locked to
staging-api.moleculesai.app; the OSS variant requires explicit auth + tenant scoping for non-localhost PLATFORM). - Cleanup failures emit
cleanup_*_failedevents with remediation hints; no silenced curl. ADMIN_TOKEN expiring mid-run surfaces as a structured event rather than a silent leak.
Activity trace caveat
If activity_trace.raw == "<endpoint_unavailable>", the per-workspace
/activity endpoint isn't wired on the target build — the bound
measurement is INCONCLUSIVE on the platform-ceiling question. Either
wire the endpoint or replace with the equivalent Datadog query. Note
that /activity accepts a since_secs query parameter; see the
endpoint handler for the supported range.
Other scripts
cleanup-rogue-workspaces.sh— emergency teardown for leaked workspaces. Prompts for confirmation. Pair with the harnesses if a cleanup trap fails (seecleanup_*_failedevents).canary-smoke.sh— quick smoke test for canary releases.dev-start.sh— local-dev platform bring-up.
The rest are self-documenting in their header comments.
