Move shutil.rmtree into a finally block so the temp directory is always
cleaned up, even when an exception occurs during download, extraction,
or file copying.
Add test_returns_none_when_skill_load_fails to verify that
build_skill_invocation_message() returns None when a registered
skill exists in the command cache but _load_skill_payload() fails.
This guards against regression of the fix in 877d01b.
build_skill_invocation_message() returns a non-empty placeholder string
('[Failed to load skill: ...]') when the skill exists in the command cache
but loading the actual SKILL.md payload fails. CLI/gateway callers treat
any truthy return value as success, so the failure is silently routed into
the model as if it were a valid skill prompt.
Return None instead, matching the existing behavior for unknown commands,
so callers using 'if msg:' can properly detect the failure.
- Remove unused from tools/tts_tool.py (dead code)
- Move _BUILTIN_DELIVER_PLATFORMS set from send() method to module
scope in gateway/platforms/webhook.py to avoid reallocation on
every call
hermes_cli/gateway.py:3702 referenced logger.debug() but 'logger' was
never defined in the module, causing a NameError at runtime if the
try/except around discover_plugins() caught an exception.
Added import logging and logger = logging.getLogger(__name__)
at module level to resolve the undefined name.
