## Description

JetBrains' first-party AI plugin, bundled across IntelliJ IDEA, PyCharm, WebStorm, and the rest of the IDE family. It provides completion, chat with project context, commit-message generation, and refactoring suggestions built on the IDE's own program model rather than on plain text — which is why its suggestions understand types and call hierarchies that a token-level tool cannot see.

It reads the project, applies edits when accepted, and sends context to JetBrains' AI service, so it declares filesystem read and write plus outbound network. Being vendor-published it takes the official trust adjustment. The setting that matters for a security review is which files are excluded from context collection: IDE-integrated assistants see everything the IDE has indexed, including configuration files that were never meant to leave the machine.

## 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. |
| `filesystem:write` | Filesystem write | Can create, edit, or delete files on the host system. High-impact capability — anything from helpful edits to planting persistence. |
| `network:outbound` | Outbound network | Can make outbound network requests. Required for hosted model providers and remote APIs; also the path for data exfiltration if combined with read access. |
