# Codex LSP

Spot problems, trace names and rename without breaking things

## What this does

You have code open in your workspace and want to know what a name points to, who else uses it, or whether giving it a new name will break something. It handles those lookups for you: it reports diagnostics, pulls up definitions, lists references and symbols, and runs a rename safety check. Reach for it whenever a change depends on knowing exactly how the pieces connect.

### Top 3 things it does for you

- Find where anything is defined
- See every place a name is used
- Check that a rename won't break anything

A scan is named by the exact content it read, not by a version number. A different version is a different artifact, and nothing here applies to a version AIR has not scanned.

## About Codex LSP

Reach for this when Codex is working in the current workspace and needs answers about the code there: diagnostics, definitions, references, symbols, or a safety check on a rename.

In practice that is the everyday set of questions: where something is defined, what else uses it, what symbols exist, and whether renaming it will cause trouble. On the diagnostics side, it surfaces problems the language server finds in the workspace.

## Questions

### Is Codex LSP safe to install?

AIR scanned this exact version of Codex LSP and flagged nothing. AIR's verdict: safe. The verdict is named by the content that was read, at commit a093ac8e3e2d, so it cannot drift onto a version nobody scanned. The full report is at https://airmarket.ai/security/lsp.

### How do I install Codex LSP?

Open https://airmarket.ai/app/lsp on Air Market and use the install action: Air Market hands Claude a prompt naming this exact skill, and Claude sets it up. Source, pinned to the exact commit this listing describes: https://github.com/code-yeongyu/oh-my-openagent/tree/a093ac8e3e2da88af1a49ac5972e0cd4a44b438b/packages/omo-codex/plugin/components/lsp/skills/lsp. Install from that link, not the branch.
