task_action must be generate, create, query, or cancel

Error message

task_action must be generate, create, query, or cancel

What it means

Raised at the top of `execute()`: `task_action` (defaulting to 'generate') must be one of generate, create, query, or cancel. The tool multiplexes four operations on one entry point and dispatches on this string — anything else means the caller's intent is unknown, so the request is rejected before any validation or paid call. `dry_run` performs the same gate.

Solutions

1. Use one of the four accepted values: 'generate' (alias of create), 'create', 'query', or 'cancel'
2. Use lowercase — the comparison is case-sensitive
3. For checking a task use `task_action: 'query'` with `task_id`; for aborting use 'cancel'

Example fix

# before
inputs = {"task_action": "status", "task_id": "csm18k..."}
# after
inputs = {"task_action": "query", "task_id": "csm18k..."}

action = str(inputs.get("task_action", "generate")).lower()
if action not in {"generate", "create", "query", "cancel"}:
    raise ValueError(f"unsupported task_action {action!r}")

def is_valid_action(a: object) -> bool:
    return str(a) in {"generate", "create", "query", "cancel"}

When it happens

Trigger: Passing `task_action: "status"`, `"delete"`, `"poll"`, or a typo like `"creat"`; passing None explicitly (str(None)='none'); assuming another tool's action vocabulary applies here.

Common situations: Porting call code from a different provider tool whose actions are named differently; LLM-generated inputs guessing action names; casing mistakes like 'Generate' (str() is compared case-sensitively against the set).
