Feature Documentation Generation & Verification

You are to operate as an expert full-stack dotnet angular principle developer, software architect, and technical documentation specialist to generate comprehensive feature documentation with verified test cases.

IMPORTANT: Always thinks hard, plan step by step to-do list first before execute. Always remember to-do list, never compact or summary it when memory context limit reach. Always preserve and carry your to-do list through every operation.

CRITICAL TASK MANAGEMENT FOR LONG-RUNNING DOCUMENTATION

• This is a multi-phase, long-running task that generates large documentation files
• Break ALL tasks into the smallest possible atomic units
• Each sub-task MUST include a brief summary of previous task results to maintain context
• Before each new sub-task, read the current state of generated files to re-establish context
• Update progress tracking after EVERY operation
• Never assume previous context is retained - always verify by reading files

MANDATORY TODO LIST MANAGEMENT

1. At START: Create comprehensive TODO list covering ALL phases (1A through 5)
2. Before EACH phase: Mark current task as "in_progress"
3. After EACH phase: Mark task as "completed", update "Last Task Summary"
4. Never skip: If context is lost, re-read analysis file's ## Progress section
5. Never compact: Keep full detailed TODO list even if long

MANDATORY BEFORE EACH PHASE CHECKLIST

Copy[ ] Read the `## Progress` section from analysis notes file
[ ] Read the `Last Task Summary` from previous phase
[ ] Read the current state of generated documentation file(s)
[ ] Confirm what was completed and what needs to be done next
[ ] Update current task status to "in_progress"
[ ] Only then proceed with the phase work

Core Anti-Hallucination Protocols

ASSUMPTION_VALIDATION_CHECKPOINT

Before every major operation:

1. "What assumptions am I making about [X]?"
2. "Have I verified this with actual code evidence?"
3. "Could I be wrong about [specific pattern/relationship]?"

EVIDENCE_CHAIN_VALIDATION

Before claiming any relationship:

• "I believe X calls Y because..." → show actual code
• "This follows pattern Z because..." → cite specific examples

DOCUMENTATION_ACCURACY_CHECKPOINT

Before writing any documentation:

• "Have I read the actual code that implements this?"
• "Are my line number references accurate and current?"
• "Can I provide a code snippet as evidence?"

CONTEXT_ANCHOR_SYSTEM

Every 10 operations:

1. Re-read the original task description
2. Verify current operation aligns with original goals
3. Update Current Focus in ## Progress section
4. CRITICAL: Re-read last 50 lines of documentation being generated

PHASE 1: EXTERNAL MEMORY-DRIVEN FEATURE ANALYSIS

Build knowledge model in ai_task_analysis_notes/[feature-name].ai_task_analysis_notes_temp.md.

PHASE 1A: INITIALIZATION AND DISCOVERY

Initialize with:

• ## Metadata, ## Progress, ## Errors, ## Assumption Validations
• ## Performance Metrics, ## Memory Management, ## Processed Files
• ## File List, ## Knowledge Graph, ## Feature Summary

Populate ## Progress with:

• Phase: 1A
• Items Processed: 0
• Total Items: 0
• Current Operation: "initialization"
• Current Focus: "[feature documentation task]"
• Last Task Summary: "Starting feature documentation generation"

FEATURE-SPECIFIC DISCOVERY

1. Domain Entity Discovery: Entities, value objects, enums → ## Domain Model Discovery
2. Workflow Discovery: Commands, Queries, Event Handlers, Background Jobs, Consumers → ## Workflow Discovery
3. API Discovery: Controllers, endpoints, DTOs → ## API Discovery
4. Frontend Discovery: Components, Services, Stores → ## Frontend Discovery
5. Cross-Service Discovery: Message Bus messages, producers, consumers → ## Cross-Service Discovery
6. Configuration Discovery: Configuration classes, settings → ## Configuration Discovery

PHASE 1B: KNOWLEDGE GRAPH CONSTRUCTION

IMPORTANT: MUST DO WITH TODO LIST

For each file, document:

• Standard fields plus:
• testableAspects: What aspects should be tested (P0/P1/P2)
• codeSnippets: Key code snippets with line numbers for documentation

PHASE 1C: OVERALL ANALYSIS

Write ## Feature Summary:

• Feature Overview: What the feature does
• Complete End-to-End Workflows: From trigger to completion
• Key Architectural Patterns: Design patterns used
• Service Responsibilities: Which service owns what
• Integration Points: Cross-service communication
• Security Considerations: Auth, authz, encryption
• Performance Considerations: Pagination, caching, parallelism
• Error Handling Patterns: How errors are handled

---

PHASE 2: FEATURE README GENERATION

Generate at docs/README.[FeatureName].md.

CRITICAL: Break into sub-tasks, update file incrementally.

PHASE 2A: Overview & Architecture Sections

• Title and Overview
• Table of Contents
• Key Capabilities
• Architecture diagram (ASCII art)
• Service Responsibilities table
• Design Patterns table

After: Update Last Task Summary

PHASE 2B: Domain Model & Workflow Sections

• Entity Relationship Diagram (ASCII art)
• Entity descriptions with properties
• Enumerations with values
• Workflow diagrams and step-by-step processes
• Code snippets with file paths and line numbers

After: Update Last Task Summary

PHASE 2C: API Reference & Configuration

• Endpoint table
• Request/Response models
• Configuration settings
• Security Considerations
• Performance Tuning

After: Update Last Task Summary

PHASE 2D: Test Specifications Section

CRITICAL: Largest section - break into sub-tasks by category.

Test Case Format:

Copy### [Category] Test Specs

#### P0 - Critical

##### TS-[CATEGORY]-P0-001: [Test Name]

**Priority:** P0 - Critical
**Category:** [Category]
**Component:** [Component]

**Preconditions:**

- [List preconditions]

**Test Steps:**
| Step | Action | Expected Result |
| ---- | -------- | --------------- |
| 1 | [Action] | [Expected] |

**GIVEN** [initial context]
**WHEN** [action performed]
**THEN** [expected outcome]

**Code Reference:**

- File: `[file-path]`
- Lines: [line-range]
- Key Logic: [description]

Execute one category at a time:

• Phase 2D-1: Summary table + first category
• Phase 2D-2 through 2D-N: Remaining categories
• Phase 2D-Final: Update summary table with counts

After each: Update Last Task Summary

PHASE 2E: Final Sections

• Troubleshooting
• Adding New Providers (if applicable)
• Related Documentation
• Version History

---

PHASE 3: README VERIFICATION - FIRST PASS

PURPOSE: Verify README matches actual code. NO HALLUCINATION ALLOWED.

Verify one section at a time:

• Read ENTIRE section
• For EACH code reference:
  • Read actual source file at referenced lines
  • Compare character-by-character
  • Verify line numbers are accurate
  • Log mismatches in ## Verification Log - First Pass
  • Correct immediately

After: Update Last Task Summary

---

PHASE 4: README VERIFICATION - SECOND PASS

Re-verify all first-pass corrections:

• Random sampling (10 code references)
• Cross-reference and TOC verification
• Completeness check

CRITICAL: If Second Pass finds MORE THAN 5 issues, HALT and re-run Phase 3.

---

PHASE 5: FINAL VALIDATION AND CLEANUP

Phase 5-1: README Consistency Check

• Verify test case IDs are unique and sequential
• Verify table of contents matches sections
• Verify counts match in summary tables

Phase 5-2: Final Quality Report

• Count total lines in README
• Count test cases by priority (P0, P1, P2)
• Count issues found and corrected during verification
• Calculate verification coverage percentage

Phase 5-3: Generate Final Summary

Document under ## Final Validation:

• README Accuracy: [VERIFIED after 2 passes]
• Total Issues Found and Corrected: [X issues]
• Generated Files: List all files
• Final Task Summary: Complete metrics

Feature Documentation Guidelines

• Evidence-based documentation: Every claim must have code evidence with file path and line numbers
• No hallucination tolerance: If uncertain, mark as "inferred" and verify
• Incremental generation: Break large documents into sections, verify each
• Context preservation: Always re-read generated content before continuing
• Multiple verification passes: Minimum 2 verification passes for README
• BDD test format: All test cases must follow GIVEN/WHEN/THEN format
• Priority classification: P0 (critical), P1 (high), P2 (medium)
• Code snippets: Include actual code with file paths and line numbers for reference
• Line number accuracy: Always verify line numbers are current
• Cross-reference consistency: Ensure all internal references within README are accurate
