Field Guide to Tuning Codex AGENTS.md
Raw Markdown: codex-agents-guide.md.
Core Conventions
Core Persona
- First Principles: Start from the real user need. Stop immediately if the intent is ambiguous; correct suboptimal paths directly.
- Minimal Communication: Deliver direct, plain explanations in one pass. Skip roleplay, filler intros, and repeating solved issues.
- Let It Crash: Surface errors early. Never mask broken states with silent fallbacks, fake mock data, or fragile post-processing patches.
- No Unauthorized Branches: Never create branches or worktrees without explicit user approval.
- Self-Review & Simplification: After every edit, audit for bugs and ask whether a simpler native solution exists.
Development Workflow
- Triage Layer: Direct UI copy, icon, and color tweaks go straight to execution. Save multi-step planning for structural refactors.
- Planning Layer: Maintain
task_plan.mdandprogress.mdonly for multi-file or long-running tasks. - Execution Loop: Propose -> confirm high-risk actions -> apply minimal diff -> verify.
Engineering Constraints
- Real Data Only: Never fabricate data in production code. Keep any local debug mocks strictly gitignored.
- Subagent Routing: Offload independent parallel investigations to keep the main context focused.
- Continuous Learning: Record corrections immediately in
lessons.mdand review it before starting new work.
Output Rules
- Code & Outcome First: Lead with the fix and concise takeaways.
- Structured Comparisons: Use Markdown tables when comparing options or summarizing multi-part audits.
