Preflight v1.0.0 — Initial Release

Think before you build.

Preflight is a universal protocol that makes AI coding agents design before they code. 5 mandatory phases, 6 driver implementations, zero dependencies.

What's included

• PROTOCOL.md — the canonical spec defining 5 phases: Orient, Clarify, Approach, Confirm, Execute
• 6 driver implementations — Claude Code, Codex (OpenAI), Gemini CLI, Goose, GitHub Copilot, Cursor
• Auto-detect installer — bash <(curl -fsSL .../install.sh) detects your drivers and installs
• 3 example transcripts — simple bug fix, complex feature, autonomous Tier C agent
• Landing page — https://agentguardhq.github.io/preflight/

Quick start

bash <(curl -fsSL https://raw.githubusercontent.com/AgentGuardHQ/preflight/main/install.sh)

Or install for a specific driver:

bash <(curl -fsSL .../install.sh) --driver claude-code

The protocol

Phase	What the agent does
1. Orient	Read relevant files, docs, recent changes. Understand what exists.
2. Clarify	Ask questions until purpose, constraints, and success criteria are clear.
3. Approach	Propose 2-3 approaches with trade-offs and a recommendation.
4. Confirm	Present the plan. No code until approved.
5. Execute	Write the code.

Core rules

• Phases 1-4 produce zero code changes
• Task-scoped, not session-scoped
• Scales down, never off — even a one-line fix runs all 5 phases
