Where Bird (MessageBird) loses the points
| Pillar | Bird (MessageBird) | What it measures |
|---|---|---|
| Discover | 100 | Can an agent find it at all: sitemap, robots, structured data. |
| Understand | 46 | Is there a spec, an llms.txt, a machine-readable description. |
| Adopt | 75 | Signup, keys, SDKs, and whether a human has to be involved. |
| Operate | 65 | Rate-limit headers, errors, status, and behaviour under load. |
