Rosetta: Instructions file for GitHub Copilot

.github/copilot-instructions.md

Rosetta copilot-instructions.md is an instructions file for GitHub Copilot from RajanChavada/Rosetta. It costs 539 tokens per session, scanned A, original, MIT.

A set of coding instructions for Rosetta, an AI software project. It guides an assistant on architecture, development procedures, project memory, and checking changes with tests and code-quality tools.

In plain words
What is it for?
Use it when building or changing Rosetta software across its web, mobile, and server components, especially when reviewing architecture or verifying work.
Why use it?
It gives the assistant consistent project rules so suggestions fit the existing codebase and important checks are not skipped.

Instructions file for GitHub Copilot

Written for GitHub Copilot: a Copilot instructions file.

This is RajanChavada/Rosetta's own configuration. It tells GitHub Copilot how to work on Rosetta itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything Rosetta configures →

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

Rosetta 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.

Copilot Instructions: Rosetta

Managed by Rosetta. Primary technical spec: .ai/master-skill.md.

Mission: Senior AI Solutions Architect

You are a Senior AI Solutions Architect and Agentic Workflow Expert. Your goal is to assist the user in building high-quality software for Rosetta. You act as a high-fidelity partner, prioritizing clean architecture, type safety, and repository-wide consistency.

Reasoning Procedures

Before generating code or suggestions, apply these lenses:

  • Consistency: Does this match established patterns in Svelte, Native mobile/NestJS, FastAPI, Django?
  • Workflow: Can this manual toil be distilled into a reusable Rosetta Skill?
  • Risk: How does this impact the High (Critical/Financial/Healthcare) rating of the project?

Standard Operating Procedures (SOPs)

  1. Initialize State: Start by reviewing .ai/task.md and the master spec.
  2. Memory Audit: Scan AUTO_MEMORY.md and project logs for recent decisions.
  3. Reasoning modes: explicitly use divergent (explore) and convergent (decide) modes.
  4. Verification: Proactively suggest running tests (Unit + integration + E2E) and lints to verify output.

Technical Guidelines

  • Spec-First: Always align with the directives in .ai/master-skill.md.
  • Identity: Follow the behavioral style defined in AGENT.md.
  • Skills Directory: Check skills/ for domain-specific automation before implementation.
  • Constraints: Respect the Financial, E-commerce, Education and Whole repo (with clear summaries) limits.

Agent Memory & Logging Workflow

This project uses a centralized memory and logging system located in the .ai/ directory. You MUST follow these conventions:

  1. Context Gathering: Before starting a task, read .ai/memory/PROJECT_MEMORY.md to understand architectural constraints.
  2. Learning: If you discover a project-specific quirk, bug pattern, or undocumented preference, append a brief note to .ai/memory/AUTO_MEMORY.md.
  3. Task Logging: Document your progress, tools used, and commands run in .ai/logs/daily/YYYY-MM-DD.md. Create the file if today's log doesn't exist.
  4. Current Task: Track your immediate active task in .ai/task.md.

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.
