Agent Integration

Add to your project rules file (.cursorrules, .clinerules, .windsurfrules, etc.):

## AITaxAdvise
Use the atx CLI for tax research.
API key is in .atx/config.json (auto-loaded).
- `atx ask "your tax question"` — get cited tax research
- `atx balance` — check remaining sessions
- `atx --help` — full reference

Configuration

Config is resolved in this order:

1. --key flag (highest priority)
2. ATX_API_KEY environment variable
3. .atx/config.json (project-scoped)
4. ~/.atx/config.json (global)

# Project-scoped (recommended for repos)
atx login --key atx_xxx --local    # saves to .atx/config.json

# Global (shared across projects)
atx login --key atx_xxx            # saves to ~/.atx/config.json

Add .atx/ to your .gitignore.
