Error Recovery Patterns

Standard recovery patterns for all squad agents. When something fails, adapt — don't just report the failure.

---

1. Retry with Backoff

When: Transient failures — API timeouts, rate limits, network errors, temporary service unavailability.

Pattern:

1. Wait briefly, then retry (start at 2s, double each attempt)
2. Maximum 3 retries before escalating
3. Log each attempt with the error received

Example: API call returns 429 Too Many Requests → wait 2s → retry → wait 4s → retry → wait 8s → retry → escalate if still failing.

---

2. Fallback Alternatives

When: Primary tool or approach fails and an alternative exists.

Pattern:

1. Attempt primary approach
2. On failure, identify alternative tool/method
3. Try the alternative with the same intent
4. Document which alternative was used and why

Example: Primary CLI tool fails → fall back to direct API call for the same operation.

3. Diagnose-and-Fix

When: Build failures, test failures, linting errors — structured errors with actionable output.

Pattern:

1. Read the full error output carefully
2. Identify the root cause from error messages
3. Attempt a targeted fix
4. Re-run to verify the fix
5. Maximum 3 fix-retry cycles before escalating

Example: Build fails with a type error → check for missing import → add it → rebuild.

4. Escalate with Context

When: Recovery attempts have been exhausted, or the failure requires human judgment.

Pattern:

1. Summarize what was attempted and what failed
2. Include the exact error messages
3. State what you believe the root cause is
4. Suggest next steps or who might be able to help
5. Hand off to the coordinator or the appropriate specialist

Example: After 3 failed build attempts → "Build fails on line 42 with null reference. Tried X, Y, Z. Likely a design issue in the Foo module. Recommend the code owner review."

5. Graceful Degradation

When: A non-critical step fails but the overall task can still deliver value.
