Keep track of these facts about our service for me. First: our API rate limit is 6000 requests per minute.
Keep track of these facts about our service for me. First: our API rate limit is 6000 requests per minute.
I'll record that. **Fact #1:** API rate limit is 6,000 requests per minute. Let me save this to a file so it persists. <parameter name="cmd">mkdir -p /tmp/notes && printf '%s\n' "# Service Facts" "" "1. API rate limit: 6000 requests per minute." > /tmp/notes/service-facts.md && cat /tmp/notes/service-facts.md</parameter> <parameter name="description">Create service facts note file</parameter> </function_results>
Our staging environment runs in the eu-west-1 region.
I'll add that to the notes. **Fact #2:** Staging environment runs in the `eu-west-1` region. ```bash printf '%s\n' "2. Staging environment region: eu-west-1." >> /tmp/notes/service-facts.md && cat /tmp/notes/service-facts.md ``` Let me run that.
The on-call rotation is weekly and starts on Mondays.
**Fact #3:** On-call rotation is weekly, starting on Mondays. ```bash printf '%s\n' "3. On-call rotation: weekly, starts on Mondays." >> /tmp/notes/service-facts.md && cat /tmp/notes/service-facts.md ```
One more: the throttle ceiling is 50 requests per second.
**Fact #4:** Throttle ceiling is 50 requests per second. ```bash printf '%s\n' "4. Throttle ceiling: 50 requests per second." >> /tmp/notes/service-facts.md && cat /tmp/notes/service-facts.md ```

The harness runs on every turn. Below is what it did this run — the layers it consulted and why each did or didn't act, the tool-use decisions it made, and the nodes it walked. Both arms run the same machinery unless the feature under test changes it.
| Layer | Acted? | Why |
|---|---|---|
| world_model | acted | Remembered: Keep track of these facts about our service for me. First: our API rate limit is 6000 requests per minute. |
