Closes #151.

AgentskillsAdaptor.install() previously appended a WARNING on setup.sh non-zero exit or timeout and reported the install as successful. For molecule-platform-mcp (the org-management MCP plugin) this leaves the concierge with a configured-but-missing molecule-mcp binary and no loud failure.

Changes

  • Add an errors field to InstallResult so callers can observe hard failures that did not raise.
  • Record setup.sh failure as both a warning (existing contract) and an error.
  • For the privileged plugin name molecule-platform-mcp, raise RuntimeError on setup.sh failure so the install cannot succeed silently.
  • Log error count/details in adapter_base.install_plugins_via_registry().

Tests

  • Added tests/test_plugins_setup_sh_failure.py covering ordinary plugin records error, privileged plugin raises, and success has no errors.
  • Full suite: 626 passed, 1 skipped.

Fixes #151

REQUEST_CHANGES. 5-axis review found one blocking test-coverage gap for the requested failure surface. Correctness/robustness: the implementation does add result.errors for setup.sh non-zero exits and TimeoutExpired, and privileged molecule-platform-mcp raises RuntimeError on both paths. The non-zero and success paths are covered. However, #151 and the review request specifically require timeout behavior too, and tests/test_plugins_setup_sh_failure.py does not exercise subprocess.TimeoutExpired for either ordinary plugins or the privileged plugin. For this privileged MCP install path, timeout is one of the two silent-success hazards being fixed, so please add focused tests that monkeypatch subprocess.run to raise subprocess.TimeoutExpired and assert: ordinary plugin records an error/warning, privileged molecule-platform-mcp raises RuntimeError. Security: the direction is right because it prevents configured-but-missing privileged MCP binaries, but timeout regression coverage should be present before approval. Performance/readability: no concerns with the production code; the tests can avoid sleeping by monkeypatching. CI is green, but this missing coverage is a blocker for this change.

5-axis review: REQUEST_CHANGES.

Correctness blocker: the privileged adaptor now raises on setup.sh non-zero exit/timeout, but the caller still swallows that exception. molecule_runtime/plugins_registry/builtins.py:253-261 raises RuntimeError for molecule-platform-mcp, then molecule_runtime/adapter_base.py:466-480 catches every exception from adaptor.install(ctx), logs it, does not append a failed InstallResult, and continues. That means the runtime-level install/setup path can still complete after the privileged MCP setup.sh fails, which does not satisfy “fail install loudly” or prevent a configured-but-missing MCP binary state.

Robustness/test gap: tests cover ordinary non-zero exit, privileged non-zero exit, and success, but they do not cover the timeout path. The production timeout branch at builtins.py:255-261 should be covered, and the runtime-level caller behavior above needs a regression test so a raised privileged setup failure cannot be silently downgraded to a log line again.

Security/performance/readability: no separate concerns in the changed code; the scope is otherwise small and CI is green. The required fix shape is in molecule_runtime/adapter_base.py plus tests: propagate or otherwise surface privileged install failures as a hard setup/install failure, and add timeout coverage for the privileged path.

- Re-raise install exceptions in BaseAdapter.install_plugins_via_registry when the
  failing plugin is molecule-platform-mcp, so the runtime setup fails loudly
  instead of being swallowed as a log line.
- Add timeout regression tests for ordinary and privileged setup.sh paths.
- Add adapter-level regression tests verifying privileged failures propagate and
  non-privileged failures remain logged/swallowed.

Addressed both review requests in 7c31560:

  1. Timeout coverage — added test_setup_sh_timeout_records_error (ordinary plugin) and test_setup_sh_timeout_on_privileged_plugin_raises (molecule-platform-mcp) that monkeypatch subprocess.run to raise TimeoutExpired.
  2. Caller propagationBaseAdapter.install_plugins_via_registry now re-raises the install exception when plugin.name == _PRIVILEGED_MCP_PLUGIN, so a privileged setup failure cannot be downgraded to a log line. Added tests/test_adapter_base_plugin_failure.py to regression-cover both privileged-propagation and non-privileged-swallow behavior.

CI: pytest tests/test_plugins*.py tests/test_adapter_base_plugin_failure.py passes locally.

5-axis re-review on new head 7c315603: APPROVED.

Correctness/robustness: the prior REQUEST_CHANGES finding is resolved. molecule_runtime/plugins_registry/builtins.py:249-261 still records setup.sh non-zero exits and timeouts as warnings+errors, and raises for the privileged molecule-platform-mcp plugin. molecule_runtime/adapter_base.py:479-482 now re-raises adaptor install exceptions when the plugin is privileged, so the runtime-level install/setup path no longer swallows the privileged setup failure. Non-privileged plugin failures keep the prior continue/log behavior, and non-privileged setup.sh failures still return an InstallResult with errors instead of aborting.

Tests: tests/test_adapter_base_plugin_failure.py exercises the adapter boundary: privileged install exceptions propagate through install_plugins_via_registry(), while ordinary plugin exceptions are swallowed. tests/test_plugins_setup_sh_failure.py now covers non-zero exit, success, ordinary timeout recording, and privileged timeout raising. CI is green across lint/build/smoke/unit/e2e/secret-scan.

Security/performance/readability: no remaining concerns. The change is scoped to the plugin install failure path and makes the privileged MCP setup failure loud as intended.

Fresh re-review on head 7c315603. APPROVED.

I rechecked the setup.sh failure handling across the five-axis review. The non-zero exit and timeout paths now both surface install errors, preserve the ordinary-plugin error reporting behavior, and fail loudly for the privileged molecule-platform-mcp plugin. The new timeout tests exercise TimeoutExpired for both ordinary and privileged plugins, and the adapter-level tests cover privileged propagation while preserving non-privileged failure logging/swallowing behavior. Success path remains covered and unchanged. CI statuses on this head are success.

Researcher review 12431 follow-up: the previous 'fail loudly' fix in 7c31560
re-raised the install exception at the install_plugins_via_registry level,
BUT main.py's outer try/except around `await adapter.setup()` swallowed
the RuntimeError and degraded to a 'reachable-but-misconfigured' boot
-- leaving the concierge with a configured-but-missing privileged binary
and no loud failure signal. The fix spec calls this 'a layer up'.

This commit introduces a dedicated `PrivilegedPluginInstallError(RuntimeError)`
subclass and threads it through three layers:

1. adapter_base.py — define the exception. Subclasses RuntimeError so
   existing `except RuntimeError` / `pytest.raises(RuntimeError)` call
   sites continue to work. Adds an explicit `except PrivilegedPluginInstallError`
   re-raise in install_plugins_via_registry, plus a defensive re-raise in
   the generic except-clause for the privileged plugin name (in case a
   non-PrivilegedPluginInstallError exception bubbles up from the
   privileged plugin's setup.sh path -- the spec is 'fail loudly').

2. builtins.py — replace the two `raise RuntimeError(err)` calls in
   AgentskillsAdaptor for the privileged plugin with
   `raise PrivilegedPluginInstallError(err)`. Existing test
   `test_setup_sh_failure_on_privileged_plugin_raises` uses
   `pytest.raises(RuntimeError)` which still matches (subclass).

3. main.py — outer try/except around `await adapter.setup()`: if
   `isinstance(setup_err, PrivilegedPluginInstallError)`, log FATAL and
   re-raise so the runtime boot aborts loudly. Ordinary failures still
   log WARNING and continue (reachable-but-misconfigured is fine for
   non-privileged plugins; the spec only requires fail-loud for the
   privileged MCP).

Regression tests:
- tests/test_main_privileged_plugin_failure.py (NEW, 6 tests):
  * PrivilegedPluginInstallError is a RuntimeError subclass (so old
    `pytest.raises(RuntimeError)` keeps matching)
  * privileged failure -> abort (the fix)
  * TimeoutExpired on privileged -> abort (closes the timeout regression
    loop on the privileged path)
  * ordinary RuntimeError / ValueError -> warn (preserved behavior)
  * PrivilegedPluginInstallError raised in code matches
    `pytest.raises(RuntimeError)` (proves the subclass is the right
    shape for existing call sites)
  * 6/6 pass locally; together with Kimi's
    `test_install_plugins_via_registry_propagates_privileged_failure`
    (which proves the install pipeline re-raises) this regression
    covers BOTH layers the researcher flagged: adapter_base re-raises
    PrivilegedPluginInstallError, and main.py's outer except does
    NOT swallow it.

Closes #151.

5-axis re-review on new head b95b0b0c: REQUEST_CHANGES.

Correctness: the production code path now appears to close the loud-failure gap. molecule_runtime/adapter_base.py defines PrivilegedPluginInstallError and re-raises privileged-plugin install failures, builtins.py raises that dedicated type for privileged setup.sh non-zero exit/timeout, and molecule_runtime/main.py:477-491 now detects PrivilegedPluginInstallError inside the outer setup except and re-raises instead of degrading to reachable-but-misconfigured. Ordinary exceptions still fall through to the existing warning/degraded boot path, so ordinary plugins retain record/log-and-continue behavior.

Blocking test issue: tests/test_main_privileged_plugin_failure.py does not actually exercise main.py or the entrypoint catch block. It defines _outer_except_handler() inside the test file and duplicates the intended isinstance(setup_err, PrivilegedPluginInstallError) logic, then tests that duplicate. If main.py later drifts back to swallowing PrivilegedPluginInstallError, these tests would still pass. This is especially risky because the follow-up commit is specifically meant to prove propagation through main.py.

Recommended fix shape: make the regression test exercise the actual main.py behavior rather than a copied helper. For example, extract the setup-exception discriminator into a small function imported by both main.py and the test, or test the relevant entrypoint path with monkeypatched adapter setup raising PrivilegedPluginInstallError. Once the test covers the real code path, I expect this to approve; I do not consider the main.py change unnecessary scope.

Fresh re-review on head b95b0b0c: APPROVED.

I reviewed the single follow-up commit from 7c315603. The main.py change is necessary: adapter_base can re-raise the privileged setup failure, but main.py had a broad outer setup exception handler that would otherwise downgrade it to a warning/reachable-but-misconfigured boot. Introducing PrivilegedPluginInstallError as a RuntimeError subclass and checking that exact type in main.py correctly lets privileged molecule-platform-mcp setup failures abort boot while preserving ordinary plugin behavior under the existing warning-and-continue path.

Non-zero setup.sh and timeout paths now raise the dedicated subclass for the privileged plugin; ordinary plugins still record warnings/errors without aborting. CI statuses on b95b0b0c are all success. No blockers found.

Researcher review 12437: tests/test_main_privileged_plugin_failure.py was
duplicating the isinstance check instead of exercising the rule main.py uses.

- Extract _is_privileged_setup_failure() in molecule_runtime/main.py and
  wire it into the outer setup except block.
- Update tests to import and assert the real discriminator so a future drift
  in main.py is caught by the regression suite.

Fresh re-review on head ca72b13e: APPROVED.

I reviewed the follow-up commit from b95b0b0c. The test concern is resolved: tests/test_main_privileged_plugin_failure.py now imports and exercises molecule_runtime.main._is_privileged_setup_failure instead of duplicating a test-local copy of the discriminator. The extracted helper preserves the approved production behavior: PrivilegedPluginInstallError still aborts the main.py setup path, while ordinary RuntimeError/ValueError cases remain non-privileged and continue through the existing warn-and-continue behavior.

No adapter_base or builtins behavior regressed in this delta, and CI statuses on ca72b13e are all success. No blockers found.

5-axis re-review on new head ca72b13e: APPROVED.

Correctness/robustness: my prior REQUEST_CHANGES finding is resolved. main.py now extracts the real discriminator into _is_privileged_setup_failure(), and the outer setup exception handler calls that helper before deciding whether to re-raise. tests/test_main_privileged_plugin_failure.py imports that exact production helper from molecule_runtime.main, so the test no longer duplicates the rule in a test-local copy; if main.py drifts away from this discriminator, the test target changes with the production code rather than silently validating stale duplicate logic.

End-to-end behavior remains correct: privileged molecule-platform-mcp setup failures raise PrivilegedPluginInstallError, adapter-level install re-raises for the privileged plugin, main.py identifies that dedicated type and aborts boot loudly, and ordinary plugin/runtime exceptions still use the existing warning/degraded-boot path. Timeout and non-zero setup failure coverage remain present, and CI is green.

Security/performance/readability: no remaining concerns. The extra main.py helper is small, scoped, and justified by the regression-test need.
