sunat-cli.crafter.ing

• RHE emission — Batch emit Recibos por Honorarios via browser automation
• F616 declaration — Monthly 4ta categoria tax declarations
• OAuth2 API — Verify emissions via SUNAT REST API
• Schema introspection — Agents self-serve field definitions at runtime

• Bun v1.2+
• agent-browser v0.22+
• Chrome or Chromium (agent-browser uses it via CDP)

bun add -g @crafter/sunat-cli

• Input hardening against hallucinations
• SKILL.md with progressive disclosure

3 SUNAT portals reverse-engineered. F616 input mask cracked via raw CDP WebSocket. reCAPTCHA bypassed through OAuth state exploitation. Full findings in RESEARCH.md.
