AI Instruction Diagnostics for coding agents. Validates the entire agentic instruction system against 120+ rules across six rule packs (core + per-agent). Supports Antigravity, Claude, Codex, Copilot, and Cursor.
Beta phase - moving fast, feedback welcome.
Quick Start

No install, no account. The headline is a single Quality score (the analysis service's verdict on how well-formed your instructions are); fix the findings that move it, run again, watch it climb:

Install permanently
npx @reporails/cli install
# or
uvx --from reporails-cli ails install
Puts ails on your PATH, installs the reporails plugin into Claude Code and Codex when they are on your machine, and prints the install steps for the other supported agents (also listed in Agent Support). ails install --project installs the plugin for the current repository only, shared with collaborators through its Claude Code settings; Codex installs for your user. ails update upgrades ails and refreshes the plugin in each agent that has it. With Pro, the step after install is /reporails:ails heal in Claude Code, which rewrites your instruction files.
