rosetta

rosetta is a skill for Claude Code, Codex from griddynamics/rosetta. It costs 16 tokens per session (339 once invoked), scanned A, original, Apache-2.0.

A routing process that matches a user request to the most suitable workflow and then guides the work through its required phases.

In plain words
What is it for?
It helps select workflows, load their instructions, track phase progress, and resume unfinished work.
Why use it?
It prevents complex engineering requests from skipping preparation, planning, execution, or validation steps.

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 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 2d 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

  • USE SKILL orchestration
  • USE SKILL hitl
  1. MUST USE FLOW <most matching workflow>.md (note: "*-flow" skills are additional workflows) — YOU MUST FULLY ALWAYS execute loaded workflow following its entire definition for all request sizes, workflow WAS created to fix your failure modes (deviations, and weak process adherence, and shallow analysis), workflow is PRIMARY deterministic process to resolve the original user request
  2. On resume/continue: load workflow state file; extract completed steps, current phase, and pending work; resume from there
  3. Once flow is loaded you MUST use workflow phases to immediately create/update todo tasks (LEDGER); open one per phase, work sequentially, close on completion immediately;
  4. In planning mode: planning + tech-specs outputs → store per system prompt, never plans/ (read-only)
  5. Hand off to the workflow — tell the user once Context loaded using Rosetta: [workflow selected + brief summary], and then execute prerequisites, phase 0, etc as workflow defined, let it drive questioning, planning, execution, review, and validation; no phase skipping;

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.
