Root cause of every prior 'rate_limit_error' on OAuth login: Anthropic
migrated all the Claude-subscription OAuth endpoints from
console.anthropic.com / claude.ai to platform.claude.com / claude.com.
The old endpoints aren't 404 — they accept the POST and return a generic
'rate_limit_error' for every request, which is what mis-led both me and
several public community implementations.
Confirmed against two current working clients (droidrun/mobilerun and
motiful/cc-gateway, both using the same Claude Code public client_id):
AUTHORIZE_URL: claude.ai/oauth/authorize
→ claude.com/cai/oauth/authorize
TOKEN_URL: console.anthropic.com/v1/oauth/token
→ platform.claude.com/v1/oauth/token
REDIRECT_URI: console.anthropic.com/oauth/code/callback
→ platform.claude.com/oauth/code/callback
SCOPE: org:create_api_key user:profile user:inference
→ ...plus user:sessions:claude_code user:mcp_servers user:file_upload
Also updated the error-hint text to mention the misleading-rate-limit
pattern for both 'malformed code' AND 'dead endpoint' cases, and to cite
the current TOKEN_URL — so if/when these move again, the next person
hitting the same trap finds the answer in the script's own output.
The CODE#STATE parsing from 0.5.0 was correct and stays. State IS sent
in the token-exchange body (verified against droidrun's working flow).
