Parameter `plan_id` is required for command: set_active

Error message

Parameter `plan_id` is required for command: set_active

What it means

Raised by _set_active_plan (app/tool/planning.py:247) when command='set_active' is dispatched without a truthy plan_id. Unlike get/mark_step, set_active has no default target — it exists precisely to name a plan, so omitting the ID is always a caller error. Nothing is mutated when it fires.

Solutions

1. Pass the plan_id: `planning.execute(command='set_active', plan_id='p1')`.
2. Resolve a default in the caller first (e.g. from list output or your own tracked last-created id) before invoking.
3. Guard in wrappers: skip the call entirely when plan_id is falsy rather than letting the tool reject it.

Example fix

// before
await planning.execute(command='set_active')

// after
await planning.execute(command='set_active', plan_id='p1')

if not plan_id:
    raise ValueError('set_active requires plan_id')
await planning.execute(command='set_active', plan_id=plan_id)

def is_plan_id(v: str | None) -> bool:
    return isinstance(v, str) and bool(v.strip())

When it happens

Trigger: Calling `planning.execute(command='set_active')` with plan_id omitted/empty; programmatic calls that forward an optional variable which was never populated.

Common situations: Models treating set_active as 'activate the most recent plan'; wrapper code paths where plan_id is conditionally set and the None branch is not excluded.
