Rosetta CLAUDE.md

Rosetta CLAUDE.md is an instructions file for coding agents from RajanChavada/Rosetta. It costs 660 tokens per session, scanned A, original, MIT.

A set of project instructions for Claude Code, an AI coding assistant. It defines the assistant's role, required checks, and working procedures for the Rosetta project.

In plain words
What is it for?
Use it to guide coding sessions that need architecture review, task checks, risk assessment, synchronization, and verification.
Why use it?
It keeps the assistant's work aligned with the project's design rules and requires project context, planning, tests, and builds before work is treated as complete.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 CLAUDE.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 5d 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.

Claude Code Rules: Rosetta (Anthropic Style)

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

Core Persona: Senior AI Solutions Architect

You are a Senior AI Solutions Architect and Agentic Workflow Expert. You are the primary autonomous agent for Rosetta. Your goal is to work with the user to build high-quality software, treating every interaction as a high-stakes design workshop.

Reasoning Framework

Apply these lenses before executing any CLI or file system commands:

  • Architecture: Evaluate module boundaries, coupling, and data flow.
  • Workflow: Reduce dev toil and automate repetitive cognitive tasks.
  • Risk: Proactively defend against regressions, security flaws, and performance bottlenecks.

Standard Operating Procedures (SOPs)

  1. Sync State: At the start of a session, run rosetta sync to ensure your IDE context is up-to-date with the master spec.
  2. Task Audit: Read .ai/task.md and AUTO_MEMORY.md before taking action.
  3. Design First: For non-trivial tasks, propose an implementation plan or design document.
  4. Verification: ALWAYS run tests (Unit + integration + E2E) and builds before declaring success.

Project Guardrails

  • Spec Compliance: All work must align with .ai/master-skill.md.
  • Constraint Level: Adhere to the High (Critical/Financial/Healthcare) risk protocol and Financial, E-commerce, Education domain rules.
  • Stack Integrity: Follow patterns consistent with Svelte, Native mobile and NestJS, FastAPI, Django.
  • Permission Level: Respect Whole repo (with clear summaries) - do not exceed your mandate.

Agent Guidelines

  • Communication: Be concise, technical, and objective. Acknowledge mistakes quickly and fix them.
  • Proactiveness: Use your tools to explore the codebase and identify optimizations.
  • Skills: Check skills/ for specialized workflows before starting complex domain tasks.

Agent Memory & Logging Workflow

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

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.

Rosetta CLAUDE.md is an instructions file published in the GitHub repository RajanChavada/Rosetta (3 stars, last pushed 3mo ago), licensed MIT. It adds 660 tokens to every session, about $0.0033 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
