power-platform-developer-suite: Instructions file for GitHub Copilot

.github/copilot-instructions.md

power-platform-developer-suite copilot-instructions.md is an instructions file for GitHub Copilot from joshsmithxrm/power-platform-developer-suite. It costs 402 tokens per session, scanned A, original, MIT.

Code-review instructions for a Power Platform developer suite, covering its architecture and rules for user interfaces, services, file access, errors, and Dataverse. Dataverse is Microsoft's data platform used by Power Platform applications.

In plain words
What is it for?
Reviewing CLI and TUI changes, checking service boundaries, validating progress and cancellation handling, and reviewing Dataverse operations.
Why use it?
It prevents business logic and file operations from being placed in the wrong layer and guides consistent error handling and data access.

Instructions file for GitHub Copilot

Written for GitHub Copilot: a Copilot instructions file.

This is joshsmithxrm/power-platform-developer-suite's own configuration. It tells GitHub Copilot how to work on power-platform-developer-suite itself, so it is not a mod to install elsewhere.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

power-platform-developer-suite copilot-instructions.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Copilot Code Review Instructions

This file guides GitHub Copilot's code review behavior for the PPDS repository.

Architecture (ADRs 0015, 0024, 0025, 0026)

Layer Rules

  • CLI/TUI are THIN presentation adapters - no business logic
  • Application Services own all business logic
  • Services are UI-agnostic - no Console.WriteLine, no Spectre/Terminal.Gui references

File I/O

  • UIs never read/write files directly
  • All file access through Application Services
  • WRONG: File.ReadAllText in command handler
  • CORRECT: await _profileService.GetProfilesAsync()

Progress Reporting

  • Services accept IProgressReporter, not write to console
  • UIs implement adapters for their display medium
  • Services return data, presentation layers format it

Error Handling

  • Services throw PpdsException with ErrorCode and UserMessage
  • Never expose technical details (GUIDs, stack traces) in UserMessage
  • UIs format errors for their medium

Dataverse Patterns

  • Use bulk APIs (CreateMultiple, UpdateMultiple) not loops with single operations
  • Use FetchXML aggregate for counting, not retrieve-and-count
  • Propagate CancellationToken through all async methods
  • Get pool client INSIDE parallel loops, not outside

Style Preferences

Do NOT suggest:

  • Converting foreach loops with if conditions to LINQ .Where() chains
  • Replacing if/else with ternary operators
  • "Simplifying" explicit control flow

These are intentional style choices per project conventions.

Valuable Findings

DO flag:

  • Code duplication across files
  • Resource leaks (missing disposal, using statements)
  • Missing CancellationToken propagation
  • Sync-over-async patterns (.GetAwaiter().GetResult())
  • Thread safety issues in async code
Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
