Wheels Bot — Triage

Classified as bug.

Suspected layer

cli — see CLAUDE.md § "CLI / MCP" and cli/lucli/ARCHITECTURE.md. The error message names modules.wheels.Module, which is cli/lucli/Module.cfc.

Fix sketch

Running wheels with no arguments causes the LuCLI runtime to look for a main function on cli/lucli/Module.cfc, which doesn't exist (Module.cfc has showHelp() but no main). The likely fix is adding a public function main() to cli/lucli/Module.cfc that delegates to showHelp() (or returns it directly), so the no-args invocation produces help text instead of the dispatch error. An alternative shape would be runtime-level fallback in cli/lucli/lib/ — but the smaller, surgical fix lives in Module.cfc.

Confidence: high

The report is clear (clear expected vs. actual behavior, deterministic repro), the suspected layer is unambiguous from the error stack, the fix shape is mechanical (one file, no design decisions), and none of the auto-downgrade rules (security/middleware/migrations/deploy/DI/cross-engine) fire — the CLI dispatch issue is engine-agnostic at this layer.

Wheels Bot — Fix proposed

Draft PR: #2842

Spec: cli/lucli/tests/specs/commands/MainCommandSpec.cfc — failing → passing (source-level scan: without main() in Module.cfc the new bundle reports totalPass:0 totalFail:3; with main() it reports totalPass:3 totalFail:0).
Implementation: cli/lucli/Module.cfc — adds public string function main() delegating to showHelp() and hides it from mcpHiddenTools().

A human review is required before merge. Reviewer A and Reviewer B will weigh in shortly. Doc updates (MDX guides, .ai/wheels/, CLAUDE.md) are handled separately by bot-update-docs.yml.
