Diagnosis Planning Skill

Generate the complete diagnostic planning report and present directly in conversation. Output should be comprehensive markdown suitable for:

• Immediate review by requesting engineer
• Copy/paste to documentation system
• Print for field use

Document Conventions

References and Citations

All technical data must include traceable footnote citations using the format [^id]: [Title](uri).

Syntax:

• Bibliographic entry: [^ref-id]: [Source Title](uri)
• Inline reference: Text with citation [^ref-id].
• Inline addition (for sources discovered mid-report): Add entry immediately after first use

URI Schemes:

• manual://{uuid} - Technical manuals
• case://{id} - Historical case records
• internal://{resource} - Internal databases
• https://... - Web sources

Image and Figure Format

All technical images must use this HTML structure with verified source attribution:

<figure>
    <img src="%verified_source_url%" title="%descriptive_title%"/>
    <figcaption>
        <p>Figure X: %Name from source%</p>
        <p>Purpose: %How this aids diagnosis - links to specific step%</p>
        <p>Details: %Key annotations visible in image%</p>
        <p>Source: %Full citation with URI%</p>
    </figcaption>
</figure>

Critical Rule: Only use src URLs explicitly returned from research. NEVER fabricate or hallucinate image paths.

Core Workflow

Step 1: Parallel Research and Information Retrieval

Conduct comprehensive parallel research to gather all diagnostic-relevant information:

1.1 Research Scope

Research these categories in parallel:

1.2 Search Query Patterns

1.3 Information Synthesis

Combine retrieved information:

• Cross-reference failure hypotheses with technical documentation
• Validate standard values against manufacturer specifications
• Prioritize causes by historical frequency and evidence strength
• Map diagrams and schematics to inspection steps
• Identify required visual aids for field reference

1.4 Evidence Review and Gap Analysis

Thoroughly analyze retrieved information before proceeding:

Identify Conflicts and Inconsistencies:

Completeness Assessment:

• Equipment background (model, year, operating hours, environment)
• Fault symptom complete description
• All possible causes identified and ranked
• Standard values for relevant parameters found
• Troubleshooting procedures verified
• Technical diagrams retrieved or noted as unavailable
• Applicable standards identified

Iterative Research Decision: If gaps or conflicts exist, judge whether additional searches are needed:

• Use alternative keywords (e.g., "hydraulic pressure" → "system pressure" → "operating pressure")
• Expand equipment model variations (e.g., "SY215C" → "SY215 series" → "Sany excavator hydraulic")
• Cross-reference with related symptoms or components
• Continue until confident or diminishing returns evident

Rule: Exhaust reasonable search avenues before concluding research. Better to over-search than under-search.

1.5 Research Tool Priority

Execute searches in this order to maximize source reliability:

Rule: Always attempt primary sources (manuals/knowledge base) before web search. Web results should be used for filling gaps, not as primary evidence. All web findings must be cross-referenced with manufacturer data when possible.

Step 2: Content Organization and Outline

Before generating the final report, systematically organize all collected information:

Create a Structured Outline:

## Report Outline

### Key Findings Summary
- Equipment: [Model, Manufacturer, Key Specs]
- Fault: [Symptom description, observed behavior]
- Primary Hypotheses: [Cause 1 - evidence], [Cause 2 - evidence]...
- Confidence Level: [High/Medium/Low based on source quality]

### Supporting Evidence by Section
- Section 2 (Equipment): Specs from [^manual-1], diagrams from [^manual-2]...
- Section 3 (Failure Analysis): Causes ranked by [^case-1], [^case-2]...
- Section 4 (Inspection): Procedures from [^manual-1]...
- [Continue for each section]

### Reference Materials Inventory
| Source ID | Document | Key Content | Target Section |
|-----------|----------|-------------|----------------|
| [^manual-1] | SY215C Technical Manual Ch. 3 | Hydraulic specs | Section 2, 5 |
| [^case-1] | Case #2023-0156 Overheat | Resolution: pump replacement | Section 3, 8 |
| [std-1] | ISO 10816 Vibration | Acceptable vibration limits | Section 5 |

Conflict Documentation:

Gap List for Section 13:

• [Spec X] not found in manual - impact: High
• [Procedure Y] not documented - impact: Medium

Stop and Review: Confirm outline covers all user requirements and collected data before proceeding to Step 3.

Step 3: Generate Comprehensive Diagnostic Planning Report

Create a detailed, field-ready report using the outline from Step 2. Verify each section against your outline:

Section 0: Document References

At the start of the report, create a ## References section listing all sources found during research using the citation format defined in Document Conventions.

Required Format (must follow exactly):

## References

[^manual-1]: [SY215C Hydraulic System Specifications, Ch. 3 Operating Parameters](manual://a1b2c3d4-e5f6-7890-abcd-ef1234567890)
[^manual-2]: [CP-2000 Technical Manual, Section 4.2 - Bearing Installation](manual://b2c3d4e5-f6a7-8901-bcde-f23456789012)
[^case-1]: [Excavator Overheat Case #2023-0156 - Root Cause Analysis](case://2023-0156)

Format Rules:

• ID naming: Use [^manual-{n}], [^case-{n}], [^std-{n}], [^web-{n}] for clarity
• Title: Format as [Section Name, Document Name] or [Case #{ID} - Brief Description]
• URI: Use actual retrieved URIs (manual://, case://, https://)
• Annotation: Add brief notes for web sources (e.g., "cross-reference only", "supplementary info")

Process:

1. Extract all sources from your Step 2 outline
2. Assign consistent IDs following the naming convention above
3. List in priority order: Manuals → Standards → Cases → Web
4. Verify each URI is from actual retrieved results
5. Include brief annotation for supplementary web sources

Verification Checklist:

• Every source cited in the report appears in Section 0
• Every entry in Section 0 is cited at least once in the report
