Retry policy

Goals

• Retry per HTTP request, not per multi-step flow.
• Preserve ordering by retrying only the current step.
• Avoid duplicating non-idempotent operations.

Defaults

• Attempts: 3
• Max delay cap: 30000 ms
• Jitter: 0.1 (10 percent)
• Provider defaults:
  • Telegram min delay: 400 ms
  • Discord min delay: 500 ms

Behavior

Discord

• Retries only on rate-limit errors (HTTP 429).
• Uses Discord retry_after when available, otherwise exponential backoff.

Telegram

• Retries on transient errors (429, timeout, connect/reset/closed, temporarily unavailable).
• Uses retry_after when available, otherwise exponential backoff.
• Markdown parse errors are not retried; they fall back to plain text.

Configuration

Set retry policy per provider in ~/.hanzo/bot/bot.json:

{
  channels: {
    telegram: {
      retry: {
        attempts: 3,
        minDelayMs: 400,
        maxDelayMs: 30000,
        jitter: 0.1,
      },
    },
    discord: {
      retry: {
        attempts: 3,
        minDelayMs: 500,
        maxDelayMs: 30000,
        jitter: 0.1,
      },
    },
  },
}

Notes

• Retries apply per request (message send, media upload, reaction, poll, sticker).
• Composite flows do not retry completed steps.
