Declared compatibility
Compatibility is declared by the source manifest. End-to-end runtime verification is coming, see below.
We're building live execution health for every listing: tool-call success rate, median latency, uptime, and last-checked timestamps, measured, not self-reported. It isn't live yet, so we don't show numbers we can't stand behind.

Stop At One
Compute a full sequence from a starting number down to 1 using the next_number tool.
Arguments
The user must provide a starting number (a positive integer greater than 1).
If no starting number is given, ask the user before proceeding.
Steps
1. Initialize
Set the current number x to the starting number provided by the user.
Begin tracking the sequence as a list: [x].
2. Call the tool
Call next_number with the current value of x.
next_number(x=)STOP and WAIT for the tool result before continuing.
3. Record the result
Append the returned value to the sequence list.
Set x to the returned value.
4. Check termination
- If
x == 1, proceed to Step 5. - Otherwise, go back to Step 2.
Important rules:
- NEVER fabricate or simulate tool call results.
- NEVER make multiple tool calls in a single response.
- ALWAYS wait for the actual tool response before deciding next steps.
5. Report the result
Print the complete sequence from start to finish, for example:
6 → 3 → 10 → 5 → 16 → 8 → 4 → 2 → 1Also report:
- Starting number
- Total steps taken (number of tool calls made)
- Maximum value reached in the sequence
