Team ID and Display Name are required to create a channel

Error message

Team ID and Display Name are required to create a channel

What it means

Thrown synchronously by CreateChannelTool._call when teamId or displayName is missing after the params merge. Above the try block at core.ts:196, so it propagates as a raw Error. The zod schema (core.ts:174) requires both teamId and displayName; membershipType defaults to 'standard'. Unreachable under valid zod-validated input unless defaultParams nullifies a required field.

Solutions

1. Always supply a non-empty teamId and displayName.
2. Verify defaultParams does not contain teamId: undefined or displayName: undefined.
3. Reorder the params spread so caller args override defaults.
4. Catch the Error at the orchestration layer.

Example fix

// before
const params = { ...arg, ...this.defaultParams }

// after
const params = { ...this.defaultParams, ...arg }

function validateCreateChannelInput(input: unknown) {
  const { teamId, displayName } = (input ?? {}) as any
  if (typeof teamId !== 'string' || !teamId.trim()) throw new Error('teamId required')
  if (typeof displayName !== 'string' || !displayName.trim()) throw new Error('displayName required')
}

function isCreateChannelArgs(x: unknown): x is { teamId: string; displayName: string; description?: string; membershipType?: 'standard' | 'private' | 'shared' } {
  return typeof x === 'object' && x !== null &&
    typeof (x as any).teamId === 'string' && (x as any).teamId.trim() !== '' &&
    typeof (x as any).displayName === 'string' && (x as any).displayName.trim() !== ''
}

try {
  if (!isCreateChannelArgs(input)) return { error: 'teamId and displayName required' }
  return await createChannelTool.invoke(input)
} catch (e) {
  return { error: (e as Error).message }
}

When it happens

Trigger: create_channel invoked without displayName; defaultParams.teamId set to undefined; agent passes only the optional fields (description, membershipType) and forgets the required ones.

Common situations: Agent prompted with a channel description but no name; defaultParams misconfigured; UI bug submitting the form before the name field is filled.
