## Description

Guides Azure Application Insights SDK setup for web applications — adding the SDK, configuring sampling and correlation, and wiring custom telemetry.

It reads and writes project files. The risk it introduces is downstream rather than immediate: instrumentation decides what leaves your application as telemetry, and an over-eager configuration can ship request bodies, headers, or user identifiers to a monitoring backend. Review what the generated configuration actually captures, not just that it compiles.

## Why it scored 20

The score starts at the catalog's neutral base of 50 and moves only through the signals below. The formula is published at https://catalog.anomity.ai/about — there is no model and no hidden heuristic.

| Signal | Contribution | Severity | Evidence |
| --- | --- | --- | --- |
| Published by the vendor | -40 | trust offset |  |
| 1 high-risk capability: filesystem:write | +10 | high |  |

Clamped result: **20/100**, band **low**.

## Capabilities

| Capability | Name | Security implication |
| --- | --- | --- |
| `filesystem:read` | Filesystem read | Can read files on the host system. Used for context, indexing, or analysis. |
