Workflow Commands

Commands for working effectively with Claude Code. Enable via workflow@tomitribe.

/design [topic]

Starts a structured design session. Claude discusses, tracks decisions, captures rejected alternatives, and documents open questions — all before any code is written. Creates a working document at docs/dev/<topic>-working-doc.md.

Use for problems that cross system boundaries, have multiple interconnected decisions, or where the first solution that comes to mind probably isn't the best one.

/improve

Reviews recent git history and proposes CLAUDE.md improvements based on what actually happened. Identifies three categories:

• Mistakes to prevent — reverts, fix commits, corrections become "DO NOT" rules
• Improvements to harden — refactors, new conventions, quality improvements become "always do it this way" rules
• Workflow patterns — repeated commands, undocumented build steps become efficiency rules

Run after completing significant work to make Claude permanently better for the next session.

/handoff

Before /clear, dumps session state to HANDOFF.md so the next session picks up cleanly. Covers what was done, decisions made, what's next, gotchas, and how to continue.

/recap

Quick "where was I?" for when you return to an open session. Summarizes what you were working on, what got done, where you left off, and what's next.
