### Dependency advisories — 32/100 (At Risk)

Matched the npm:@paypal/agent-toolkit@1.11.0 runtime dependency closure — what installing the published package pulls in — 243 packages. Reachability is not analyzed.

| Criterion | Status | Points | Detail |
|---|---|---|---|
| Direct dependencies free of known advisories | partial | 7.9 / 35 | 3 affected: @langchain/core 0.3.6 (high 8.6), mathjs 14.9.1 (high 8.8), ai 4.3.19 (low 3.7) |

### High-Risk Jurisdiction Exposure — 100/100 (Exceptional)

| Criterion | Status | Points | Detail |
|---|---|---|---|
| Policy exposure multiplier | met | 100 / 100 | no confirmed policy-scope location match |

## AI Readiness — 41/100 (Weak)

How well is the repo equipped to be developed and maintained with AI coding agents? Carries a deliberately small weight: agent tooling is a real maintenance signal, but its absence must never gate the top of the scale (calibration saturates at raw 91, so 100/100 remains reachable with AI Readiness at zero).
