Preflight

A Claude Code plugin that brings Google Senior Architect-style reviewability to every session.

Overview

Preflight transforms Claude Code into an architect-grade coding assistant. Before executing any unfamiliar commands or file operations, it provides inline explanations of its intent — improving security, reviewability, and team collaboration.

Features

• Intent Transparency: Before any non-trivial operation, explains what Claude plans to do
• Architect-Grade Review: Semantic explanations help teams understand and audit AI actions
• Zero External Dependencies: All explanation logic runs locally — no external LLM services involved
• Seamless Integration: Works automatically on session start via SessionStart hook

How It Works

When active, Preflight injects additional context that makes Claude Code output explanations prefixed with ദി(⎚_⎚ ) before operations such as:

• File creation and editing
• Shell command execution
• Multi-file modifications

Trivial commands (ls, cd, cat, pwd, git status, etc.) execute directly without explanation.

Example Output

ദി(⎚_⎚ ) Install ESLint dependencies, configure TypeScript parser, set up linting rules for code quality.

Installation

This plugin is distributed via the Claude Code plugin marketplace. To install:

1. Open Claude Code settings
2. Navigate to Plugins
3. Search for "preflight"
4. Click Install

Or via the CLI:

Configuration

Preflight works out of the box with no configuration required. The plugin automatically activates on every Claude Code session.

Hook Details

Preflight uses a SessionStart hook that runs a local bash script. This script injects context into Claude Code's session, enabling the explanation behavior without any external services.
