Agent Advisor — Security skill for Claude Code

Agent Advisor

One routing model, three execution harnesses.

**This repo is maintainer infrastructure — there is nothing here to install.** To *use* selective routing, install the plugin for your harness:

• claude-advisor (Claude Code)
• gem-advisor (Antigravity)
• sol-advisor-portable (Codex):
  • Adds 2 primary chairs (Daybreak Blue and Astra)
  • Adds a one-command installer that works on any machine, stops safely instead of overwriting your setup, a check command to verify the install, short names to pick Sol / Astra / Daybreak, a /sol shortcut, and setup instructions for multiple devices.

This repo exists so those three stay honest with each other.

It is public for one reason: [`specs/`](specs/) and the [comparison matrix](#the-comparison-matrix) are worth reading whether or not you ever touch the sync tooling. They are a written-down account of what the same routing model costs to enforce on three different harnesses — including where one of them cannot enforce it at all.

Agent Advisor is the canonical hub for three standalone implementations of the same selective-routing workflow: **Sol Advisor** on Codex, **Claude Advisor** on Claude Code, and **Gem Advisor** on Google Antigravity. The routing model lives here in [`specs/`](specs/). Each harness's source lives in [`platforms/`](platforms/) and is exported outward to its own repository by [`scripts/sync-spokes.sh`](scripts/sync-spokes.sh).

The workflow originates with [Sol Advisor](https://github.com/DannyMac180/sol-advisor) by Daniel McAteer, MIT licensed. See [ORIGIN.md](ORIGIN.md) for what is carried over, what is newly built, and how close each adaptation actually is.
