Add raxol

[DROOdotFOO]

raxol is a coding agent on the BEAM. It serves over ACP from a self-contained Burrito binary, so there is no Erlang or Elixir install required on the host.

Distribution

Raw binaries from a GitHub release, one per platform, each pinned by SHA-256:

platform	asset
linux-x86_64	raxol_cli_linux
linux-aarch64	raxol_cli_linux_arm
darwin-aarch64	raxol_cli_macos
windows-x86_64	raxol_cli_windows.exe

Command is raxol acp.

Authentication

Both accepted methods are supported, and each carries its _meta type marker rather than relying on the untyped default:

• Agent Auth — authenticate runs the OAuth flow in-process: binds a loopback port, opens the browser, catches the redirect, exchanges the code with PKCE, stores the credential. Offered for OpenRouter, which is the provider with a public PKCE flow intended for third-party local applications.
• Terminal Auth — raxol login, for every other provider. The client relaunches the same binary with args: ["login"].

Validation run locally

$ python3 .github/workflows/build_registry.py
Added agent: raxol v0.2.6

$ python3 .github/workflows/verify_agents.py --agent raxol --auth-check
  → Verifying SHA-256...
  → Auth check: .../extracted/raxol acp...
  ✓ Success: Auth OK: openrouter(agent), terminal(terminal)
Passed: 1   Failed: 0   Skipped: 0

Schema validates, the icon is 16x16 monochrome currentColor, and all four archive URLs return HTTP 200.

One note that may be worth a look on your side, unrelated to this entry: when verify_agents.py skips an agent (I hit a SHA-256 mismatch from a cached download, since --clean keeps downloads), the run still prints All tests passed! with Passed: 0 Skipped: 1. A CI job reading that summary would treat a checksum mismatch as green. --clean-all was the fix on my side.
