🙌 LSP-Integrated File Editing Tools

[arnm]

I’ve added a set of file editing tools for CodeCompanion agents in Neovim, inspired by OpenCode. These tools help LLM agents work with files more efficiently and safely:

codecompanion-lsp-files-edits.mp4

Tools

• Write File Tool
  Create or overwrite files, with LSP formatting and diagnostics right after.

• Edit File Tool
  Replace text in a file using smart matching (handles whitespace, indentation, etc.), then runs LSP formatting and checks for errors.

• Multi-Edit File Tool
  Batch multiple edits to a file in one go—each edit is applied in sequence, and the whole thing is atomic (all succeed or none). LSP formatting and diagnostics run at the end.

---

Why use these?

• Faster agent turnaround: Agents can apply fixes, refactors, or even implement features and get instant feedback from the LSP—no need to remember to run tests or formatting manually.
• Atomic and safe: Multi-edit is all-or-nothing, so you won’t end up with half-applied changes.
• Async and event-driven: Doesn’t block your editor.

This is especially useful for more capable LLMs that can plan and apply several changes at once.

If you’re building agent workflows or want to automate code changes safely, these are worth a look!

I hadn’t heard about OpenCode before, thanks for sharing! It does look really promising. I’ve actually been playing with Gemini-cli the past few days; it’s fun having all those free tokens 😂

With so many extensions out there now, I’m planning to create a GitHub org and add them all as proper CodeCompanion extensions. I’ll invite you to join! since it's your extensions :)

While it’s great to check the LSP, many tools are already included in the plugin, but I see the value in something like multi-edit.

Thank you!

Hey man, can you allow me to join if you plan to create an organization

I've been working on gitcommit related extensions recently, including git tools
