Can my team use this, or is it a single-developer tool?

Arness works in team settings. Configuration lives in CLAUDE.md (committed to the repo), so everyone on the team gets the same directories, templates, and patterns. Pattern documentation (code-patterns.md, testing-patterns.md, architecture.md) is generated from your actual codebase and shared via git.

There are also "teams" variants for key skills: /arn-code-feature-spec-teams runs multi-agent debate on feature specs, /arn-code-execute-plan-teams uses agent teams for complex execution. The artifacts — specs, plans, reports — are committed and reviewable by teammates.

One caveat: each developer runs Arness in their own Claude Code session. There's no shared server or real-time collaboration — coordination happens through git, PRs, and issues like normal.
