Against the five tests
The map is scored for a specific reader: a firm of roughly 20 to 500 people, no CISO and no compliance department, using agents it bought and agents it built, looking for a named document it can check itself against.
| Test | The question | Score |
|---|---|---|
| Agent-scoped | Covers agents, tools, MCP and autonomy, not AI in general. | ◐ |
| Adopter-facing | Usable by a firm deploying agents, not only building them. | ◐ |
| Checklist-shaped | Enumerable requirements you can pass or fail. | ✔ |
| Right-sized | Digestible without dedicated security staff. | ◐ |
| Recognised | A name a client, auditor or insurer would accept. | ✔ |
✔ yes · ◐ partly · ✘ no · scores are this site’s reading of the document

✘One model or system lifecycle; no multi-agent scope.
✔ addresses it · ◐ names it, within one system · ✘ does not
