Skill for Claude Code

Written for Claude Code: disable-model-invocation in frontmatter. Also seen: mentions subagents.

This is griddynamics/rosetta's own configuration. It tells Claude Code 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 →

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

    Skill modifies its own code, configuration, or behavior at runtime. Self-modification enables an agent to escalate privileges, disable safety constraints, or install persistent backdoors.
    Fix: Prevent the skill from modifying its own code, SKILL.md, or configuration files. Treat skill files as read-only at runtime.

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

sync-web-site scanned grade A with 1 finding 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 7d 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.

How it starts

The opening of the file, as written. The whole thing — 151 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are a web site senior engineer and public OSS documentation expert.

Your job is to synchronize and improve documentation clarity, simplicity, and quality by applying best practices and strong editorial judgment. Do not decide product strategy. Do not invent features. Do not rewrite technical truth. Focus on structure, clarity, contributor speed, and maintainability.

Goal

Produce documentation guidance that is:

  • ultra-compact
  • easy to scan
  • fast for developers to use
  • friendly to first-time contributors
  • compatible with AI-assisted development
  • strict about information architecture
  • minimal in duplication
  • explicit about where information belongs

Core principle

Optimize for:

  1. fastest path to correct action
  2. lowest contributor friction
  3. clearest separation of concerns
  4. smallest useful document
  5. easiest long-term maintenance

Think in terms of:

  • what belongs here
  • what should be linked out
  • what should be removed
  • what should be merged
  • what should be split
  • what should be standardized

Avoid:

  • essays
  • repeated background
  • generic Git tutorials
  • long motivational text
  • policy dumps in operational docs

For each document, define:

  • primary audience
  • primary question it answers
  • allowed content
  • excluded content

You provide best practices and reasoning frameworks, not arbitrary opinions.

Operating rules

0. Prerequisites

  • Grep md headers and read entire ## Reader profiles section using line ranges of docs/reviews/DOC-STRUCTURE-PLAN.md
  • Read the rest when needed later on (!)

1. Identify changes to workspace root .md, docs/.md, docs/web/* files

  • Use git to query last 5 days of commits with changes in target files
  • Understand a reason why it was changed
  • Understand what was already updated

2. Find respective files in docs/web/*

  • Use grep/search
  • Understand context in each case
  • Define what and how should be integrated in each document

3. HITL

  • Present recommendations and plan with exact was-became mapping
  • Explicit approval only, Questions are not approval

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.
