A single counter that works for Gmail, Calendar, or Tasks — same function, different inputs. What two parameters let you make the reader generic?
The action enum and the name of the list key — messages for Gmail, items for Calendar? The function takes both and does the call on your behalf?
Exactly. Pass the action and the key; the counter handles the rest with a try/except around the read. One function, zero API-specific branches:
try:
result = toolset.execute_action(action, {})
return len(result.get(list_key, []))
except Exception:
return -1
And when I want to count Gmail, I pass Action.GMAIL_FETCH_EMAILS and "messages" — for Calendar, I pass Action.GOOGLECALENDAR_FIND_EVENT and "items"?
Exactly. Two arguments parameterise the whole counter. Caller swaps them per API, the wrapper stays untouched:
def count_with_fallback(action, list_key: str) -> int:
try:
result = toolset.execute_action(action, {})
return len(result.get(list_key, []))
except Exception:
return -1
What if an API needs params — like Gmail wants max_results? Does the generic counter drop that?
The generic signature stops at "count what comes back with no filter." If the caller needs a cap, add a third param — params: dict = None with a {} default — and forward it to execute_action. Keep the base API tiny; extend only when a real caller needs it.
So one wrapper replaces three hand-written counters — and the sentinel -1 carries the failure signal through every API?
One wrapper, any API, one sentinel. The pattern generalises every shape you've seen this month: pass the enum, pass the key, get a safe count.
TL;DR: Parameterise the action and the list key — one safe counter covers every Composio read.
Action.GMAIL_FETCH_EMAILS, Action.GOOGLECALENDAR_FIND_EVENT, etc."messages", "items", "files"-1 on any read failure| API | Call |
|---|---|
| Gmail | count_with_fallback(Action.GMAIL_FETCH_EMAILS, "messages") |
| Calendar | count_with_fallback(Action.GOOGLECALENDAR_FIND_EVENT, "items") |
| Tasks | count_with_fallback(Action.GOOGLETASKS_LIST_TASKS, "items") |
Callers compose by passing data, not by branching on enum values.
