## Description

Supermaven is an AI code completion extension that is built around a custom model designed for very low latency and a context window large enough to feed entire repositories. It targets VS Code, JetBrains, Neovim, and a handful of other editors, and is one of the few extensions in the autocomplete category that markets sub-100ms response times as a primary differentiator.

Its declared capabilities are deliberately narrow for a category that often over-asks. The extension reads files in the open workspace to assemble context for completions, makes outbound network requests to Supermaven's hosted completion service, and reads the locally stored Supermaven credential. It does not request filesystem write access — the IDE handles insertion of accepted suggestions — and does not execute shell commands.

Supermaven is community trust because it is published by an independent vendor rather than a marketplace platform. The credential plus outbound network pairing is the only one that lights up Anomity's risk signals, and it does not match any dangerous combination. The residual concern is the standard one for hosted-completion products: source code from your workspace is transmitted to the vendor on every request, so teams under confidentiality controls should validate Supermaven's data-handling terms before adopting it broadly.

## Why it scored 50

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 |
| --- | --- | --- | --- |
| Established community project | -10 | trust offset |  |
| 1 high-risk capability: credentials:access | +10 | high |  |

Clamped result: **50/100**, band **medium**.

## Capabilities

| Capability | Name | Security implication |
| --- | --- | --- |
| `filesystem:read` | Filesystem read | Can read files on the host system. Used for context, indexing, or analysis. |
| `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. |
| `credentials:access` | Credentials access | Reads provider API keys, OAuth tokens, or other secrets from the host keychain or environment. |
