Description

Summary

Add Cline (VS Code) support to RTK.

How Cline works

Cline uses .clinerules file in project root for custom rules, and hooks in ~/Documents/Cline/Rules/Hooks/ or .clinerules/hooks/ for scripts.

PreToolUse hooks can cancel commands but cannot rewrite them. contextModification injects text into conversation context.

Implementation

Rules-based approach (like Windsurf/Codex):

  • rtk init --agent cline creates .clinerules with RTK instructions
  • Optional: PreToolUse hook for tracking via rtk gain

Research direction
The issue proposes adding a new subcommand `rtk init agent cline` to generate a `.clinerules` configuration file for Cline. Start by examining the existing agent integrations (e.g., Windsurf/Codex) in the codebase to understand the pattern, likely located in a command handling module like `src/cli/mod.rs` or similar. Then implement the new subcommand with a help flag and a template generator that writes the `.clinerules` file. Optionally, explore the PreToolUse hook integration for tracking via `rtk gain`. The references in the issue provide documentation for Cline hooks and rules.
