Multi-person projects - shared state, todo claiming, handoffs

Team Coordination Skill

Load with: base.md

Purpose: Enable multiple Claude Code sessions across a team to coordinate and work together without conflicts. Manages shared state, todo claiming, decision syncing, and session awareness.

Core Philosophy

┌─────────────────────────────────────────────────────────────────┐
│  TEAM CLAUDE CODE                                               │
│  ─────────────────────────────────────────────────────────────  │
│  Multiple devs, multiple Claude sessions, one codebase.         │
│  Coordination > Speed. Communication > Assumptions.             │
│                                                                 │
│  Before you start: Check who's working on what.                 │
│  Before you claim: Make sure nobody else has it.                │
│  Before you decide: Check if it's already decided.              │
│  Before you push: Pull and sync state.                          │

Team State Structure

When a project becomes multi-person, create this structure:

_project_specs/
├── team/
│   ├── state.md              # Who's working on what right now
│   ├── contributors.md       # Team members and their focus areas
│   └── handoffs/             # Notes when passing work to others
│       └── [feature]-handoff.md
├── session/
│   ├── current-state.md      # YOUR session state (personal)
│   ├── decisions.md          # SHARED - architectural decisions
│   └── code-landmarks.md     # SHARED - important code locations
└── todos/
    ├── active.md             # SHARED - with claim annotations
    ├── backlog.md            # SHARED
    └── completed.md          # SHARED

Workflow

Starting a Session

Claiming a Todo

In active.md, add claim annotation:

## [TODO-042] Add email validation

**Status:** in-progress
**Claimed:** @alice (2024-01-15 10:30 EST)
**ETA:** Today

...

During Work

  • Update state.md if you touch new files
  • Check decisions.md before making architectural choices
  • If you make a decision, add it to decisions.md immediately
  • Push state updates every 1-2 hours (keeps team in sync)

Ending a Session

┌─────────────────────────────────────────────────────────────────┐
│  END SESSION CHECKLIST                                          │
│  ─────────────────────────────────────────────────────────────  │
│  1. Commit your work (even if WIP)                              │
│  2. Update your current-state.md                                │
│  3. Update team state.md (status → Paused or Done)              │
│  4. If passing to someone: create handoff note                  │
│  5. Unclaim todo if abandoning                                  │
│  6. Push everything                                             │

Creating a Handoff

When passing work to another team member, create:

_project_specs/team/handoffs/auth-feature-handoff.md:

# Handoff: Auth Feature (TODO-042)

**From:** @alice
**To:** @bob
**Date:** 2024-01-15

## Status

70% complete. Core auth flow works, need to add:
- [ ] Password reset flow
- [ ] Email verification

## What's Done

- Login/logout working
- JWT tokens implemented
- Session management done

## What's Left

1. Password reset - see src/auth/reset.ts (skeleton exists)
2. Email verification - need to integrate SendGrid

## Key Decisions Made

- Using JWT not sessions (see decisions.md)
- Tokens expire in 7 days
- Refresh tokens stored in httpOnly cookies

## Watch Out For

- The `validateToken` function has a weird edge case with expired tokens
- Don't touch `authMiddleware.ts` - it's fragile rn

## Files to Start With

1. src/auth/reset.ts - password reset
2. src/email/verification.ts - email flow
3. tests/auth.test.ts - add tests here

## Questions?

Slack me @alice if stuck

Conflict Prevention

File-Level Awareness

Before modifying a file, check state.md for who's touching what:

## Active Sessions

| Contributor | Working On | Started | Files Touched | Status |
|-------------|------------|---------|---------------|--------|
| @alice | TODO-042 | ... | src/auth/*, src/middleware/* | 🟢 Active |

If you need to touch src/auth/* and Alice is working there:

  1. Check if it's truly conflicting (same file? same functions?)
  2. Coordinate via Slack before proceeding
  3. Add a note to "Conflicts to Watch" section

Pre-Push Check

Before pushing, always:

git pull origin main
# Resolve any conflicts
git push

PR Tagging

Always tag area owners in PRs:

## PR: Add password reset flow

Implements TODO-042

cc: @alice (auth owner), @bob (reviewer)

### Changes
- Added password reset endpoint
- Added email templates

### Testing
- [ ] Unit tests pass
- [ ] Manual testing done

Decision Syncing

Before Making a Decision

  1. Pull latest decisions.md
  2. Check if decision already exists
  3. If similar decision exists, follow it (consistency > preference)
  4. If new decision needed, add it and push immediately

Decision Format

## [2024-01-15] JWT vs Sessions for Auth (@alice)

**Decision:** Use JWT tokens
**Context:** Need auth for API and mobile app
**Options:**
1. Sessions - simpler, server-side state
2. JWT - stateless, works for mobile
**Choice:** JWT
**Reasoning:** Mobile app needs stateless auth, JWT works across platforms
**Trade-offs:** Token revocation is harder, need refresh token strategy
**Approved by:** @bob, @carol

Commands

Check Team State

# See who's working on what
cat _project_specs/team/state.md

# Quick active sessions check
grep "🟢 Active" _project_specs/team/state.md

Claim a Todo

  1. Edit _project_specs/todos/active.md
  2. Add claim annotation to todo
  3. Update _project_specs/team/state.md
  4. Commit and push

Release a Claim

  1. Remove claim annotation from todo
  2. Update state.md (remove from Claimed Todos)
  3. Commit and push

Git Hooks for Teams

Pre-Push Hook Addition

Add team state sync check to pre-push:

# In .git/hooks/pre-push (add to existing)

# Check if team state is current
echo "🔄 Checking team state..."
git fetch origin main --quiet

LOCAL_STATE=$(git show HEAD:_project_specs/team/state.md 2>/dev/null | md5)
REMOTE_STATE=$(git show origin/main:_project_specs/team/state.md 2>/dev/null | md5)

if [ "$LOCAL_STATE" != "$REMOTE_STATE" ]; then
    echo "⚠️  Team state has changed on remote!"
    echo "   Run: git pull origin main"
    echo "   Then check _project_specs/team/state.md for updates"
    # Warning only, don't block
fi

Claude Instructions

At Session Start

When user starts a session in a team project:

  1. Check for _project_specs/team/state.md

  2. If exists, read it and report:

    • Who's currently active
    • What todos are claimed
    • Any conflicts to watch
    • Recent announcements

  3. Ask what they want to work on

  4. Check if it's already claimed

  5. Help them claim and update state

During Session

  • Before touching files, check if someone else is working there
  • Before making decisions, check decisions.md
  • Remind user to update state periodically

At Session End

  • Prompt user to update state.md
  • Ask if they need to create a handoff
  • Remind them to push state changes

Single → Multi-Person Conversion

When a project needs team coordination:

  1. Run /check-contributors
  2. Create _project_specs/team/ structure
  3. Initialize state.md and contributors.md
  4. Add claim annotations to active todos
  5. Update CLAUDE.md to reference team-coordination.md skill
