 # Contributing
 
-Thanks for contributing to Claude Agent Teams UI.
+Thanks for contributing to Claude Agent Teams UI!
 
-## Project Philosophy & Scope
+## Before You Start
 
-claude-devtools exists to make the invisible parts of Claude Code visible — the token flows, context injections, tool executions, and session dynamics that are otherwise hidden behind the CLI. It is not a general-purpose dashboard or an IDE.
+For big features and major changes, please discuss them in our [Discord](https://discord.gg/RgBHMBsn) first so we can figure out the best approach together and avoid conflicts.
 
-Our priorities:
-
-1. **Parity with Claude Code** — When Claude Code ships new capabilities (agent teams, context tracking, new tool types), we adopt them quickly so users always have full visibility.
-2. **Context engineering insight** — Features that help users understand *what* is consuming their context window, *how* tokens flow through a session, and *where* to optimize. If it doesn't help someone make better decisions about their Claude Code usage, it probably doesn't belong here.
-3. **Stability over novelty** — A reliable, fast tool for professional workflows. We'd rather do fewer things well than many things poorly.
-
-**What we generally do not accept:**
-- Large custom features that don't directly serve context visibility or Claude Code parity.
-- Speculative features that add maintenance burden without solving a concrete problem users face today.
-- PRs that significantly expand scope without prior discussion in an Issue.
-
-If you're considering a non-trivial contribution, **open an Issue first** to check alignment with the current roadmap. This saves everyone time and keeps the project focused.
+Small fixes, bug reports, and minor improvements are always welcome -- just open a PR.

 ## Pull Request Guidelines

+- Keep changes focused and small -- one purpose per PR.
 - Add/adjust tests for behavior changes.
 - Update docs when changing public behavior or setup.
 - Use clear PR titles and include a short validation checklist.
-- **Large changes (new features, new dependencies, large data additions) must have a discussion in an Issue first.** Do not open a large PR without prior agreement on the approach.
 - Avoid committing large hardcoded data blobs. If data can be fetched at runtime or generated at build time, prefer that approach.

 AI coding tools are welcome, but **you are responsible for what you submit**:
 
 - **Review before submitting.** Read every line of AI-generated code and understand what it does. Do not submit raw, unreviewed AI output.
-- **Do not commit AI workflow artifacts.** Planning documents, session logs, step-by-step plans, or other outputs from AI tools (e.g. `docs/plans/`, `.speckit/`, etc.) do not belong in the repository.
-- **Test it yourself.** AI-generated code must be manually verified — run the app, confirm the feature works, check edge cases.

 ## What Does NOT Belong in the Repo
 - Personal planning/workflow artifacts (AI session plans, task lists, etc.)
 - Large static data that could be fetched at runtime

 ## Commit Style
 - Prefer conventional commits (`feat:`, `fix:`, `chore:`, `docs:`).
