| description | Graceful degradation workflow for continuing tasks when web search tools fail, using internal knowledge with verification caveats |
Search Fallback Workflow
When to Apply
Use this workflow when:
search_web tool fails repeatedly (typically 2+ consecutive failures)
- External information is needed but unavailable due to tool limitations
- Task completion is still possible with reasonable confidence using internal knowledge
- The output can include appropriate caveats about verification needs
Core Pattern
-
Detect Search Failure
- Monitor
search_web responses for errors, empty results, or timeouts
- After 2 consecutive failures, assess whether the task can proceed without fresh data
-
Assess Feasibility
- Determine if internal knowledge is sufficient for the task at hand
- Identify which sections/claims require external verification
- Evaluate risk level: Can the task proceed safely with caveats?
-
Proceed with Internal Knowledge
- Continue the task using well-established facts, regulations, or principles
- Prioritize accuracy over completeness when uncertain
- Use conservative language for claims that cannot be verified
-
Flag for Verification
-
Document Limitations
- Include an explicit note in the output about search unavailability
- List specific items requiring follow-up verification
- Provide recommendations for manual verification steps
Implementation Template
## Execution Notes
**Search Tool Status**: Unavailable during generation
**Confidence Levels**:
- ✓ High confidence: Established regulations, well-documented facts
- ⚠ Medium confidence: Industry standards, commonly accepted practices
- ✗ Requires verification: Time-sensitive data, recent changes, specific citations
**Verification Checklist**:
- [ ] Verify citation: [specific reference]
- [ ] Confirm current status: [specific item]
- [ ] Review recent updates: [specific topic]
Code Pattern for Agents
search_attempts = 0
max_search_attempts = 2
search_failed = False
for query in required_searches:
result = search_web(query)
if result.success:
process_result(result)
else:
search_attempts += 1
if search_attempts >= max_search_attempts:
search_failed = True
log_warning("Search tool unavailable, proceeding with fallback")
break
if search_failed:
content = generate_with_internal_knowledge()
add_verification_flags(content)
document_limitations_in_summary()
Example Output Structure
When using this fallback, structure documents with clear sections:
# Document Title
## Disclaimer
This document was generated with limited access to external verification tools.
Items marked with [VERIFICATION NEEDED] should be confirmed before final use.
## Content Sections
[Standard content with internal knowledge]
## Items Requiring Verification
- Topic A: Current regulatory status needs confirmation
- Topic B: Recent policy changes should be checked
- Topic C: Specific citations require source validation
## Recommendations
1. Cross-reference with official sources
2. Verify time-sensitive information
3. Consult subject matter experts for critical decisions
Best Practices
- Don't fabricate citations - Better to flag as unverified than invent sources
- Use conservative language - "Generally," "Typically," "Commonly" instead of absolutes
- Prioritize safety - If misinformation could cause harm, recommend manual verification
- Track what's missing - Maintain a clear list of items needing follow-up
- Be transparent - Clearly communicate limitations to end users
When NOT to Use This Pattern
- Tasks requiring current/real-time data (stock prices, news, weather)
- Legal or medical advice requiring authoritative sources
- Compliance documentation where citations are mandatory
- Situations where incorrect information could cause significant harm
