name: anti-conflict description: Prevent file conflicts between multiple AI agents working in parallel version: 3.2.0

Anti-Conflict Protocol Skill

Purpose

Prevent file conflicts between multiple AI agents working in parallel. Implements a 7-phase workflow with mandatory worktree usage, lock files, and QA validation.

When to Use

• At session start (Phase 1)
• Before any file edit (Phase 2)
• When editing coordination-required files (Phase 3)
• Before commits (Phase 4)
• During long sessions (Phase 5)
• At session end (Phase 6)
• Before closing session (Phase 7)

7-Phase Protocol

Phase 1: Session Start

Copygit worktree list              # Check active worktrees
cat .worktrees/tasks.md        # Check IN_PROGRESS tasks
cat .worktrees/sessions.json   # Check active sessions
ls .worktrees/*.lock           # Check lock files
git status                     # Check uncommitted changes
git log --oneline -3           # Verify expected state

Phase 1.2: Worktree Creation (Mandatory)

Copygit worktree add .worktrees/{agent-hex}-{feature} -b {tipo}/{name}
cd .worktrees/{agent-hex}-{feature}

Phase 1.5: Lock File Protocol

For protected files (CLAUDE.md, README.md, CSVs):

1. Create lock: cp .worktrees/session_lock.template.json .worktrees/{id}.lock
2. Update heartbeat every 15 min
3. Remove lock when done
4. Stale detection: >30 min without heartbeat

Phase 2: Pre-Edit Validation

Copygit status --short | grep {file}
# M or MM → DO NOT EDIT (another agent working)
# ?? or CLEAN → Safe to edit

Phase 3: Coordination-Required Files

High-risk files requiring explicit coordination:

• CLAUDE.md
• README.md
• 02_processed_data/*.csv
• .worktrees/tasks.md

Phase 4: Commit Discipline

• ALWAYS: git add {specific-files} (NEVER git add .)
• Atomic commits (one purpose per commit)
• Include agent: tipo(escopo): desc - Agent: {name}

Phase 5: Frequent Integration

For sessions >1 hour:

Copygit fetch origin
git log HEAD..origin/main --oneline

Phase 6: Session End

1. Commit all pending changes
2. Update tasks.md: IN_PROGRESS → COMPLETED
3. Decide: keep or remove worktree
4. Sign modified documents

Phase 7: QA Validation (Mandatory)

Before closing session:

1. Spawn Claude-QA-{prime-hex}-final
2. Provide list of completed tasks
3. Wait for validation report
4. Register QA result in sessions.json

QA Checklist

• Commits realizados (git log)
• Arquivos modificados consistentes
• tasks.md atualizado
• sessions.json sem inconsistências
• Documentos assinados
• Worktrees limpos
• Nenhum arquivo órfão ou conflito
