[IMPORTANT] Use

TaskCreate

to break ALL work into small tasks BEFORE starting — including tasks for each file read. This prevents context loss from long files. For simple tasks, AI MUST ask user whether to skip.

Quick Summary

Goal: Interactive feature implementation with comprehensive knowledge graph analysis and external memory management (same core as

feature

skill).

MANDATORY IMPORTANT MUST Plan ToDo Task to READ the following project-specific reference doc:

• project-structure-reference.md

  -- project patterns and structure

If file not found, search for: project documentation, coding standards, architecture docs.

Workflow:

1. Phase 1: Discovery — Initialize analysis file, search codebase, build file list, knowledge graph
2. Phase 2: Plan Generation — Detailed implementation plan following project patterns
3. Phase 3: Approval Gate — Present plan, await user confirmation
4. Phase 4: Execution — Implement with safeguards, update external memory

Key Rules:

• External Memory: All analysis in

  .ai/workspace/analysis/{task}.analysis.md

• Evidence-Based: grep/search to verify assumptions, never assume service ownership
• Approval Required: STOP at Phase 3, do NOT proceed without user confirmation
• High Priority Files: Domain Entities, Commands, Queries, EventHandlers, Controllers MUST be analyzed

Skill Variant: Use this skill for interactive feature development where the user is actively engaged and can provide feedback. For autonomous feature implementation, use

tasks-feature-implementation

. For investigating existing features without changes, use

feature-investigation

.

Implementing a New Feature or Enhancement

You are to operate as an expert full-stack dotnet angular principal developer, software architecture to implement the new requirements in

[task-description-or-task-info-file-path]

.

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. Todo list must cover all phases, from start to end, include child tasks in each phases too, everything is flatted out into a long detailed todo list.

Prerequisites: MUST READ

.claude/skills/shared/understand-code-first-protocol.md

and

.claude/skills/shared/evidence-based-reasoning-protocol.md

before executing.

PHASE 1: EXTERNAL MEMORY-DRIVEN KNOWLEDGE MODEL CONSTRUCTION

Your sole objective is to build a structured knowledge model in a Markdown analysis file at

.ai/workspace/analysis/[some-sort-semantic-name-of-this-task].analysis.md

with systematic external memory management.

PHASE 1A: INITIALIZATION AND DISCOVERY

First, initialize the analysis file with a

## Metadata

heading and under it is the full original prompt in a markdown box, like this:

markdown [content of metadata in here]

(MUST 5 chars for start and end of markdown box), then continue add the task description and full details of the

Source Code Structure

from

.ai/docs/prompt-context.md

into this

## Metadata

section, with all content in

## Metadata

section must be in a markdown box, like this:

markdown [content of metadata in here]

(MUST 6 chars for start and end of markdown box).

You MANDATORY IMPORTANT MUST also create the following top-level headings:

• ## Progress

• ## Errors

• ## Assumption Validations

• ## Performance Metrics

• ## Memory Management

• ## Processed Files

• ## File List

• ## Knowledge Graph

Populate the

## Progress

section with:

• Phase: 1
• Items Processed: 0
• Total Items: 0
• Current Operation: "initialization"
• Current Focus: "[original task summary]"

Next, do semantic search and grep search all keywords of the task to find all related files, prioritizing the discovery of core logic files like Domain Entities, Commands, Queries, Event Handlers, Controllers, Background Jobs, Consumers and front-end Components .ts.

CRITICAL: Save ALL file paths immediately as a numbered list under a

## File List

heading.

After semantic search, perform additional targeted searches to ensure no critical infrastructure is missed:

• grep search

  with patterns:

  .*EventHandler.*{EntityName}|{EntityName}.*EventHandler

• grep search

  with patterns:

  .*BackgroundJob.*{EntityName}|{EntityName}.*BackgroundJob

• grep search

  with patterns:

  .*Consumer.*{EntityName}|{EntityName}.*Consumer

• grep search

  with patterns:

  .*Service.*{EntityName}|{EntityName}.*Service

• grep search

  with patterns:

  .*Helper.*{EntityName}|{EntityName}.*Helper

• All files (include pattern:

  **/*.{cs,ts,html}

  )

High Priority files MUST be analyzed: Domain Entities, Commands, Queries, Event Handlers, Controllers, Background Jobs, Consumers and front-end Components .ts.

Update the

Total Items

count in the

## Progress

section.

PHASE 1B: KNOWLEDGE GRAPH CONSTRUCTION

IMPORTANT MUST DO WITH TODO LIST

Count total files in file list, split it into many batches of 10 files in priority order, each group insert in the current todo list new task for Analyze each batch of files group for all of files in file list.

CRITICAL: You must analyze all files in the file list identified as belonging to the highest IMPORTANT priority categories: Domain Entities, Commands, Queries, Event Handlers, Controllers, Background Jobs, Consumers and front-end Components .ts.

For each file in the

## File List

(following the prioritized order if applicable), read and analyze it, add result into

## Knowledge Graph

section. The heading of each analyzed file must have the item order number in heading. Each file analyzing result detail the following information:

Core Fields:

• filePath

  : The full path to the file

• type

  : The component's classification

• architecturalPattern

  : The main design pattern used

• content

  : A summary of purpose and logic

• symbols

  : Important classes, interfaces, methods

• dependencies

  : All imported modules or

  using

  statements

• businessContext

  : Comprehensive detail all business logic, how it contributes to the requirements

• referenceFiles

  : Other files that use this file's symbols

• relevanceScore

  : A numerical score (1-10)

• evidenceLevel

  : "verified" or "inferred"

• uncertainties

  : Any aspects you are unsure about

• frameworkAbstractions

  : Any framework base classes used

• serviceContext

  : Which microservice this file belongs to

• dependencyInjection

  : Any DI registrations

• genericTypeParameters

  : Generic type relationships

For Consumer Files (CRITICAL):

• messageBusAnalysis

  : When analyzing any Consumer file (files ending with

  Consumer.cs

  that extend the project message bus consumer base class), identify the

  *BusMessage

  type used. Then perform a grep search across ALL services to find files that send/publish this message type. List all producer files and their service locations in the

  messageBusProducers

  field. This analysis is crucial for understanding cross-service integration.

Targeted Aspect Analysis: Populate

specificAspects:

key with deeper analysis:

• For Front-End items:

  componentHierarchy

  ,

  routeConfig

  ,

  routeGuards

  ,

  stateManagementStores

  ,

  dataBindingPatterns

  ,

  validationStrategies

• For Back-End items:

  authorizationPolicies

  ,

  commands

  ,

  queries

  ,

  domainEntities

  ,

  repositoryPatterns

  ,

  businessRuleImplementations

• For Consumer items:

  messageBusMessage

  ,

  messageBusProducers

  ,

  crossServiceIntegration

  ,

  handleLogicWorkflow

MANDATORY PROGRESS TRACKING: After processing every 10 files, you MANDATORY IMPORTANT MUST update

Items Processed

in

## Progress

, run a

CONTEXT_ANCHOR_CHECK

, and explicitly state your progress. After each file, add its path to the

## Processed Files

list.

PHASE 1C: OVERALL ANALYSIS

Write comprehensive

overallAnalysis:

summary showing:

• Complete end-to-end workflows discovered
• Key architectural patterns and relationships
• All business logic work flow: From front-end to back-end. (Example: Front-end Component => Controller Api Service => Command/Query => EventHandler => Others (Send email, producer bus message); From background job => event handler => others)
• Integration points and dependencies

---

PHASE 2: PLAN GENERATION

You MUST ensure all files are analyzed. Then read the ENTIRE Markdown analysis notes file. Then Generate a detailed implementation plan under a

## Plan

heading. Your plan MANDATORY IMPORTANT MUST follow coding convention and patterns in

.ai/docs/prompt-context.md

, must ultrathink and think step-by-step todo list to make code changes, for each step must read

.ai/docs/prompt-context.md

to follow code convention and patterns.

PHASE 2.1: VERIFY AND REFACTOR

First, verify and ensure your implementation plan that code patterns, solution must follow code patterns and example in these files:

• docs/backend-patterns-reference.md

• docs/frontend-patterns-reference.md

• docs/code-review-rules.md

Then verify and ensure your implementation plan satisfies clean code rules in

docs/code-review-rules.md

---

PHASE 3: APPROVAL GATE

You must present the plan for my explicit approval. DO NOT proceed without it.

Format for Approval Request:

## Implementation Plan Complete - Approval Required

### Summary

[Brief description of what will be implemented]

### Files to Create

1. `path/to/file.cs` - [purpose]
2. `path/to/file.ts` - [purpose]

### Files to Modify

1. `path/to/existing.cs:line` - [change description]
2. `path/to/existing.ts:line` - [change description]

### Implementation Order

1. [Step 1]
2. [Step 2]
3. [Step N]

### Risks & Considerations

- [Risk 1]
- [Risk 2]

**Awaiting approval to proceed with implementation.**

---

PHASE 4: EXECUTION

Once approved, execute the plan. Before creating or modifying ANY file, you MANDATORY IMPORTANT MUST first load its relevant entry from your

## Knowledge Graph

. Use all EXECUTION_SAFEGUARDS. If any step fails, HALT, report the failure, and return to the APPROVAL GATE.

EXECUTION_SAFEGUARDS:

• Verify file exists before modification
• Read current content before editing
• Check for conflicts with existing code
• Validate changes against project patterns

---

SUCCESS VALIDATION

Before completion, verify the implementation against all requirements. Document this under a

## Success Validation

heading and summarize changes in

changelog.md

.

Coding Guidelines

• Evidence-based approach: Use

  grep

  and semantic search to verify assumptions
• Service boundary discovery: Find endpoints before assuming responsibilities
• Never assume service ownership: Verify patterns with code evidence
• Project-patterns-first approach: Use established templates
• Cross-service sync: Use an event bus, not direct database access
• CQRS adherence: Follow established Command/Query patterns
• Clean architecture respect: Maintain proper layer dependencies

Architecture Reference

Backend Layers

Presentation:   Controllers, API endpoints
Application:    Commands, Queries, EventHandlers, DTOs
Domain:         Entities, ValueObjects, Expressions
Infrastructure: Repositories, External services, Messaging

Key CQRS Flow

Controller → Command/Query → Handler → Repository → Entity
                                  ↓
                            EventHandler → Side Effects (notifications, external APIs)

Message Bus Flow

Service A: EntityEventProducer → message broker → Service B: Consumer

Frontend Flow

Component → Store.effect() → ApiService → Backend
     ↑           ↓
   Template ← Store.state

Project Framework Patterns (see docs/backend-patterns-reference.md)

// Command/Query handlers — search for: CqrsCommandApplicationHandler, CqrsQueryApplicationHandler
// Entity event handlers (for side effects) — search for: EntityEventApplicationHandler
// Message bus consumers — search for: MessageBusConsumer
// Repositories — search for: service-specific repository interface

Frontend Patterns

// Component hierarchy
project base component (search for: base component class)            // Simple display
project store component base (search for: store component base class)     // State management
project form component base (search for: form component base class)        // Forms with validation

// Store pattern
project store base (search for: store base class)<TState>
effectSimple(() => api.call().pipe(tapResponse(...)))

IMPORTANT Task Planning Notes (MUST FOLLOW)

• Always plan and break work into many small todo tasks
• Always add a final review todo task to verify work quality and identify fixes/enhancements
