cancel requires an operation id

Error message

cancel requires an operation id

What it means

The /security slash command's `cancel` subcommand requires an operation id argument. handleSecurityCommand throws this when the user runs `/security cancel` with no (or only whitespace) arguments, since coordinator.cancel() cannot identify which operation to cancel without an id.

Solutions

1. Supply an operation id: `/security cancel <id>`
2. List active operations first with the list subcommand, then copy an id from its JSON output
3. Interactively type the command followed by a space and the id, then submit

Example fix

// before
/security cancel
// after
/security cancel op-1a2b3c

const id = rest.trim();
if (!id) throw new Error("cancel requires an operation id");
await handleSecurityCommand(runtime, `cancel ${id}`);

null

null

When it happens

Trigger: Running `/security cancel` or `/security cancel ` (empty/whitespace `rest`) inside a coding-agent session.

Common situations: User forgets the operation id, copies an incomplete command, or expects the CLI to cancel the 'current' operation implicitly — the command has no implicit default.
