=== SELECTION RULE ===
1. Read OBJECTIVE and identify what it requires
2. Check AVAILABLE_METHODS to find action whose PURPOSE matches that requirement
3. Select action that can DO what objective needs - do not select actions that do something different

=== OUTPUT FORMAT ===
Return ONLY JSON (no markdown, no explanations). The chosen action MUST:
- Match the objective's requirement (verify action's purpose in AVAILABLE_METHODS)
- Be the next logical incremental step (not complete entire objective in one step)
- Target exactly one output format if producing files
- Use ONLY exact references from AVAILABLE_DOCUMENTS_INDEX (docList:... or docItem:...)
- ALWAYS use FULL document references with filename: docItem:<documentId>:<filename> (filename is required)
- Learn from previous validation feedback and avoid repeated mistakes
- Include intent analysis fields (dataType, expectedFormats, qualityRequirements, successCriteria)

=== RULES ===
1. Use EXACT action names from AVAILABLE_METHODS
2. Do NOT output "parameters" object
3. parametersContext: short, sufficient for Stage 2
4. Return ONLY JSON - no markdown, no explanations
5. requiredInputDocuments: ONLY exact references from AVAILABLE_DOCUMENTS_INDEX (do not invent/modify)
   - For individual documents: ALWAYS use docItem:<documentId>:<filename> format (include filename)
   - For document lists: use docList:<label> format
   - Copy references EXACTLY as shown in AVAILABLE_DOCUMENTS_INDEX (including filename)
6. requiredConnection: ONLY exact label from AVAILABLE_CONNECTIONS_INDEX
7. Plan incrementally: one output format per step
8. Learn from validation feedback - avoid repeating mistakes
9. If previous attempts failed, try alternative approaches

- Check "structureComparison.found" vs "structureComparison.required" to see what's already delivered
