AyCode.Blazor — Domain Rules

🛑 AI AGENT CORE PROTOCOL (CRITICAL ENFORCEMENT)

You are operating in a multi-repo, documentation-first architecture. You MUST STRICTLY follow this protocol for every response. Failure to do so will break the workspace rules.

1. MANDATORY OUTPUT PREFIX: Your response MUST begin exactly with this format on the very first line: [LOADED_DOCS: <comma-separated list of .md files currently in your context>] (If no .md files are loaded yet, write [LOADED_DOCS: NONE].)

2. HARD-GATE DELAY (DOCS BEFORE CODE) & TOOL EXECUTION BLOCK:

   • If [LOADED_DOCS: NONE] applies, you MUST STOP and you are STRICTLY FORBIDDEN to use the following tools: code_search, get_symbols_by_name, find_symbol, or get_file (for non-markdown files).
   • Your VERY FIRST AND ONLY allowed tool calls must be file_search or get_file targeting the .md documentation in the relevant docs/ folders or README.md.
   • Do not answer the user's core question until the [LOADED_DOCS] list is populated with the base architecture files.
   • CRITICAL EXCEPTION: Do NOT re-read .md files that are already mapped in your context or LOADED_DOCS list (strictly maintain rule 15).

3. 🛑 CRITICAL TOOL EXECUTION FIREWALL (NO RE-READING): BEFORE you invoke get_file, file_search, or run_command_in_terminal targeting any .md file, you MUST physically verify if its name appears in your [LOADED_DOCS] list OR in the user's prompt context.

   • IF YES (IT IS CACHED): You are HARD-LOCKED from using any tool to read or search it again. You must extract the answer STRICTLY from your existing context memory.
   • PENALTY: Using a tool to re-read an already mapped .md file causes catastrophic context duplication and wastes resources. Treat [LOADED_DOCS] as an absolute firewall blocking all further file reads for those specific files.

4. CONTEXT RECOVERY (SMART READ): If the user asks a domain/architecture specific question and you realize the essential .md files are NO LONGER in your current context (they dropped out of memory), you MUST automatically re-read the necessary documentation before answering. Do NOT wait for the user to explicitly tell you to re-read them. Prioritize scanning the docs/ folders to recover the lost context.

   Directories to read (when recovering context):

   • docs/ (in this repository root)

5. EXPLICIT CONSENT FOR MODIFICATIONS: NEVER rewrite, create, or delete code/files without the user's explicit permission. If the user does not specifically request a code modification (e.g., using phrases like "we are just thinking," "what do you think," "let's plan"), you MUST ONLY provide text-based analysis and planning. You are FORBIDDEN from using file-modifying tools (replace_string_in_file, edit_file, create_file, etc.) until the user explicitly says "ok", "go ahead", "implement", or a similar unambiguous approval.

Workspace Dependencies

own-dep-repos: "name: path" — paths are relative to this repo root (.github/..)

@repo { name = "AyCode.Blazor" type = "framework" layer = 1 own-dep-repos = ["AyCode.Core: ../AyCode.Core"] }

This is the single source of truth for Blazor/MAUI UI domain rules. Do not duplicate these elsewhere. For core framework rules see: ../AyCode.Core/.github/copilot-instructions.md For detailed docs see: README.md → docs/ External repos in own-dep-repos are fully accessible — read their source code, docs, and .github/copilot-instructions.md freely when you need type definitions, base classes, or context. Do not limit yourself to the current workspace.

DevExpress Components

1. DevExpress Blazor 25.1.3 — always use DxGrid, DxFormLayout, etc. Do NOT mix with generic Blazor component libraries.
2. Grid system uses AcSignalRDataSource for real-time data — grids fetch data via SignalR, not REST.
3. CardView components wrap DevExpress grids with card-style layout for mobile-friendly display.

Architecture

4. Blazor.Components is the main UI library — both Blazor Server and MAUI Hybrid consume it.
5. Blazor.Models = shared view models (client + server). Blazor.Models.Server = server-only scaffolding.
6. MAUI.Core targets Android (API 33+), iOS (15.0+), Windows (10.0.19041+) via platform folders.
7. Controllers project is scaffolding — do not add business logic here.

Serialization in UI

8. SignalR uses AcBinaryHubProtocol (custom binary) — not the default JSON protocol.
9. Grid filters use AcExpressionNode serialization — LINQ expressions are serialized and sent to server.

Conventions

10. Do not suggest removal/rollback as a solution — find a fix for the problem.
11. All DLL references to AyCode.Core projects are via DllReference (not ProjectReference) — this is intentional, required for build isolation and nopCommerce plugin compatibility in consuming projects.
12. No redundant code — before writing new logic, check whether similar methods already exist in the current context. Reuse or extract shared logic into smaller methods rather than duplicating.
13. Keep all .md documentation in sync (PASSIVE DETECTION & ASK FIRST) — If you notice any contradiction, error, or missing information between the code and your currently loaded .md files, briefly notify the user and ask for permission before making changes. Do NOT automatically update .md files or trigger new searches yet. Once the user approves, you may actively search, read, and update the necessary docs in the correct layer. Identify missing documentation: If you notice during your task that a frequently used pattern, underlying logic, or important behavior is missing from the docs, and adding it would improve future LLM context-efficiency (saving searches/tokens), briefly notify the user to get approval. Topic-based separation: When creating or expanding documentation, keep logically distinct features or domains in separate .md files (e.g., architecture, data model, billing) and only reference them in the main/index documents. Do not cram everything into a single monolithic file. Keep in mind: these .md files are primarily for LLM grounding and context providing. Keep them concise, structured, and focused on rules/patterns rather than human-readable prose. ENFORCEMENT: At the end of EVERY code-modifying response, append a [DOCUMENTATION CHECK] section. Evaluate ONLY the .md files already in your context. State in 1-2 sentences if you found discrepancies or missing concepts, and ask if they should be documented. DO NOT trigger searches or tool calls for this initial check.
14. Documentation layering — write .md documentation at the defining layer (where the code lives). Higher-layer .md files reference the base docs (e.g. see AyCode.Core/docs/SIGNALR.md) and document only project-specific overrides or extensions. Never duplicate base-layer descriptions in consumer-level docs.
15. Do not re-read .md files already in your context window. They only change if you modify them yourself (new content is already in context) or if the developer tells you they changed — in that case re-read them once.
16. Folder navigation — start from the root README.md for solution-level navigation. When you need to understand a folder's contents or find a type/class, read the README.md in that folder first — it indexes the local files and sub-folders. Follow this before grepping or reading source files.

Related Solutions

17. AyCode.Core solution (../AyCode.Core/AyCode.Core.sln) contains all core framework code (SignalR, serialization, data sources, base classes, interfaces). Types referenced in this Blazor solution but not defined here (e.g. AcSignalRDataSource, AcBinaryHubProtocol, IId<TId>, AcObservableCollection, AcLoggerBase) likely live in AyCode.Core.
