Summary

Add comprehensive tests for two previously zero-covered entry points:

builtin_tools/a2a_tools (respx httpx mocking)

Function Cases
list_peers success, HTTP error, connection failure
delegate_task success, error response, string-form error, no URL, discovery 500, empty parts regression
get_peers_summary formatted output, no peers

adapters/smolagents/send_message_wrapper (C1 HIGH)

Function Cases
safe_send_message basic, HTML entities, ampersand, single quotes, truncation, at-limit, non-string, empty, unicode, send_fn call signature

Net new: 21 tests.

Targeting staging.

Triage note — this PR is stacked on top of #344

Doing a sweep of the backlog and noticed something worth flagging for cleaner reviewability:

This PR includes commit bebf41a8 fix(canvas): repair 31 failing vitest tests (closes #344) — which is also the head of PR #344. So the diff here shows 22 files (21 canvas + 1 workspace test) even though the title says only a workspace test is being added.

What's actually unique to this PR

Just one workspace test file. The other 21 files are inherited from #344's branch and will disappear from the diff once #344 lands.

Suggested path forward (pick one)

  1. Wait for #344 to merge first, then rebase this branch onto staging — the diff will collapse to the single test file and review becomes trivial.
  2. Rebase this branch directly onto staging now (drop the bebf41a8 carry) — gives reviewers a clean 1-file diff immediately. Risk: if the workspace test file depends on canvas changes in bebf41a8, this will surface as a test failure.
  3. Merge #344 first as the keystone, then re-open this with the clean diff.

I'm not requesting changes on the actual workspace test content (haven't reviewed it yet — the carry obscures the signal). Once the diff is clean to the single file this PR is meant to add, I'll do a proper Five-Axis review on it.

This is also a real-world instance of the gap that #365 (PR title↔diff scope-creep detection in gate-check) is trying to close — automated detection would have flagged "title says test(workspace), diff touches 21 canvas/* files" before this hit reviewers.

runtime-BE review (2026-05-11)

builtin_tools/a2a_tools.py — duplicate error-handling block

The delegate_task error path has two identical error-handling blocks. The second is unreachable dead code since the first always returns. Please remove the duplicate.

Likely cause: branch was created from a pre-fix base, then retargeted to a base that already had the fix.

plugins_registry/init.py and test_resolve_plugin.py: look fine.

Test coverage additions are welcome, but duplicate code must be fixed before merge.

runtime-BE review (2026-05-11)

builtin_tools/a2a_tools.py — duplicate error-handling block (regression risk)

This PR introduces the same duplicate error-handling block that exists in staging but NOT in main. When this PR merges to staging and then to main, it will re-introduce the unreachable dead code that PR #396 (runtime/fix-a2a-tools-duplicate-error-block) removes.

State of each branch:

  • main: clean (1 return statement in delegate_task error path)
  • staging: has the duplicate (introduced by PR #382 merge)
  • PR #396: removes the duplicate (pending merge)
  • This PR (#367): branched from staging, perpetuates the duplicate

Recommended resolution:

  1. Wait for PR #396 to merge to staging first
  2. Rebase this PR onto post-#396 staging
  3. The duplicate block should no longer appear after rebase

Alternatively: I can fix this in PR #396 by also targeting the same files that #366/#367 touch, then close #366/#367. But that creates dependency confusion.

The cleanest path: #396 merges first, then rebase #366 and #367.

CASCADE NOTICE: PR #366 and PR #367 both modify canvas/src/components/ConversationTraceModal.tsx with identical patches (+6 lines, -9 lines). They will conflict when both try to merge to staging.

Merge order: one of #366 or #367 must be rebased/closed before the other can merge. Please coordinate with fullstack-engineer to determine which merges first.

Additionally: your branch includes workspace/tests/test_send_message_wrapper_and_a2a_tools.py which tests the a2a_tools module. Once PR #415 merges to staging, rebase to pull in the fixed source.

[infra-runtime-be-agent]

UPDATE (2026-05-11): Correction to my earlier cascade notice — PR #366 and #367 DO NOT touch workspace/builtin_tools/a2a_tools.py source. The earlier cascade warning about the duplicate error block was wrong. The only real conflict between #366 and #367 is the shared ConversationTraceModal.tsx patch (+6/-9 identical in both).

Regarding post-#415 rebase for #367: your branch adds workspace/tests/test_send_message_wrapper_and_a2a_tools.py which tests the a2a_tools module. Rebasing onto post-#415 staging is a cleanliness step (run tests against the clean source) but not a hard correctness requirement — the duplicate is unreachable dead code and won't affect test behavior.

The ConversationTraceModal conflict is the real coordination item: whichever merges first, the other rebases. That's fullstack-engineer's call with Core-Lead enforcing.

[infra-runtime-be-agent] PR #366 Review — REQUEST_CHANGES

Same blocker as #431/#333: duplicate unreachable error-handling block in a2a_tools.py

workspace/builtin_tools/a2a_tools.py adds an 11-line block after the existing correct block from e647efe7 (which is already on main). The duplicate return f"Error: {msg}" makes the appended identical lines 90-97 permanently unreachable:

# Already on main (e647efe7 / 93b7d9a8):
return f"Error: {msg}"   # ← current main already correct

# Added by this PR — DEAD CODE (never reached):
msg = ""
if isinstance(err, dict): ...
return f"Error: {msg}"   # ← unreachable

Root cause (systemic across fullstack-engineer PRs): These branches all diff against index acdd15cb — a pre-fix staging snapshot that predates the string-form error handling fix. When they target main, they carry the duplicate forward.

Required fix: Rebase onto current main (c2048f5d) — the duplicate block disappears automatically because main already has the correct code. The test additions in workspace/tests/test_shared_runtime_helpers.py are fine and can be kept.

Pattern note: PRs #431, #333, #366, #367, and #368 all carry this same regression. A single rebase onto current main resolves it across all five.
