description	Use when GrokBuild needs to understand or respond to automatic comment-checker feedback emitted after an edit-like PostToolUse hook (lfg native hook).

GrokBuild Comment Checker (lfg)

lfg registers a Grok PostToolUse hook for successful edit-like tools (write, edit, multi_edit, and equivalents).

When comment-checker reports a warning after a patch, the session receives bounded feedback and should fix or explain the flagged comment before moving on.

Scope

• No MCP tool is required for the native Grok path.
• Non-edit tools are ignored.
• Missing checker binaries emit no hook output so normal GrokBuild work can continue.
• Fail-closed on malformed hook JSON (matches lfg hook discipline).

Cross-host note

Upstream OMO may brand this as a Codex plugin skill. On GrokBuild the same skill is about lfg native PostToolUse feedback, not a Codex-only runtime.
