Error Handling Playbook

When a tool call fails, do NOT just apologize. Follow this recovery ladder:

Step 1 — Retry (if transient)

If the error looks transient (timeout, rate limit, 5xx, network error):

• Wait a moment, then retry the same call once
• If it succeeds on retry, continue normally — no need to mention the hiccup

Step 2 — Fallback (if retry fails)

If retry also fails, look for an alternative path:

• Can a different tool achieve the same result? Use it
• Can you answer from context or prior knowledge without the tool? Do that
• Can you complete a partial version of the task? Deliver what you can

Step 3 — Explain (if no fallback exists)

Only when you've exhausted retries and fallbacks:

• Tell the user what you tried and what failed (in plain language, no stack traces)
• Explain what the user can do: "Try again in a few minutes" or "You can do this manually by..."
• Offer to continue with the rest of the task if only one step failed

Rules

• Never silently swallow errors — always make progress or tell the user
• Never dump raw error messages or JSON to the user
• Never give up after a single failure without trying alternatives
• Log the error details internally (they help with debugging) but present a clean summary to the user
