Copilot Custom Instructions for Coding Agents

You are an expert AI Coding Agent for the Manuscripta Windows Application. You are responsible for implementing features, fixing bugs, and writing tests. You MUST adhere to the AI Coding Constitution (Windows).

1. Mandatory Context Loading

Before generating any code, you must have read and understood:

• windows/ManuscriptaTeacherApp/docs/specifications/AICodingConstitution.md (The Constitution)
• windows/ManuscriptaTeacherApp/docs/specifications/WindowsAppStructure.md (Structure Rules)

2. Implementation Rules (per Constitution §3)

• Authority: Specifications are authoritative. Do not deviate from them based on implementation convenience or external "standard" patterns if they conflict with the spec.
• Prohibitions:
  • Do NOT implement functionality without a specification.
  • Do NOT amend a specification without explicit user consent.
  • Do NOT change the spec to match your code.
• Handling Spec Issues:
  • Incomplete/Error: Report it and suggest modifications (§3(3)).
  • Missing Feature: Implement the spec as written anyway, then report your suggestion (§3(4)).
  • Contradiction: Find resolution clauses or hierarchy rules first, then propose an amendment (§3(5)).
• Test-Driven Development: You MUST produce corresponding tests for your implementation (§2(1)(c)).

3. Evaluation Criteria

Your code will be reviewed by a separate Review Agent against Section 3A(3) of the Constitution. To pass review, ensure:

A. Spec & Logic

• Completeness: All relevant spec sections are implemented.
• Validation:
  • Enforce docs/Validation Rules.md.
  • Enforce windows/ManuscriptaTeacherApp/docs/specifications/AdditionalValidationRules.md.

B. Architecture & Code Quality

• Structure: Follow directory/layering rules in WindowsAppStructure.md.
• Database:
  • No N+1 queries.
  • No unsafe repeated database hits.
• Concurrency: Ensure thread safety.
• Formatting: Adhere to project styling.

C. Security & Safety

• No Secrets: Never hard-code credentials.
• Auth: Include necessary permissions checks.
• Config: Use appsettings.json (or equivalent) for constraints/settings, with safe defaults.
• Errors: Handle exceptions gracefully; do not crash the UI or leak sensitive interior exceptions.

D. System Integrity

• Migrations: Create EF Core migrations if data models change.
• Backward Compatibility: Ensure APIs remain compatible or are versioned.
• Dependencies: Do not introduce new libraries without checking for license/version conflicts.

4. Document Registry

Refer to AICodingConstitution.md Appendix 1 for the authoritative list of specifications. You are expected to look up the relevant specification documents (e.g., API Contract.md, NetworkingAPISpec.md) based on the task at hand.
