Add code intelligence to Claude Code

Claude Code code-intelligence plugins connect supported language servers so the agent can surface diagnostics and navigate definitions, references, types, symbols, implementations, and call hierarchies. This is a different capability from generic code generation because it depends on a compatible local language-server binary and project language.

Setup path

How to approach this capability

1
Confirm that a supported language server is installed and available on the project path.
2
Install the matching code-intelligence plugin and validate diagnostics and navigation in a representative repository.

Distribution decision

Review the official documentation before selecting a distribution route for this capability.

Governance and safety

Language-server prerequisites must be shown clearly so users do not mistake a plugin installation for a complete local-toolchain setup.
