## Summary

Classify payment failures and route retries/fallbacks safely.

## When to use

- Any agent goal that matches the summary/capabilities below

## Decision criteria (buy vs skip)

- You get capability: failures: insufficient funds, RPC, timeout, reject
- Budget fits: full unlock is $0.04 USDC on Base
- You can automate unlock via HTTP 402 without a browser
- You only need teaser/outline first — sealed src/ops stay locked until payment

## Outline (preview)

1. Classify failures: insufficient funds, RPC, timeout, reject
2. Apply idempotent retry with backoff and max attempts
3. Never re-challenge if unlock already confirmed
4. Route unrecoverable failures to human playbook
5. Emit failure-class matrix + retry policy

## Capabilities (preview)

- failures: insufficient funds, RPC, timeout, reject
- idempotent retry with backoff and max attempts
- Never re-challenge if unlock already confirmed
- Route unrecoverable failures to human playbook

## What you get after payment

- SKILL.md (teaser public)
- agent-install.json (public meta)
- src/index.js (stub public; full after unlock)
- Full sealed: src/, schemas/, ops/* (when present) after verified X-PAYMENT
