trajectory action must be start, stop, status or replay

Error message

trajectory action must be start, stop, status or replay (got ${JSON.stringify(args.action)})

What it means

Argument-validation guard in resolveTool for the 'trajectory' action: args.action matched none of start/stop/status/replay, so no trajectory wire command could be resolved. The offending action value is included in the message.

Solutions

1. Check the action field sent on the trajectory call: only start, stop, status and replay are accepted; fix the typo or unsupported verb and resend.
2. Log or print args.action at the call site to see the exact rejected value — the message embeds its JSON serialization for this reason.
3. If you need a new trajectory verb, extend the switch in resolveTool with an explicit case that maps to a concrete tool name instead of relying on the fallback error.
