The instruction itself

as written by the author

Run a diagnosis on the current session:

cozempic current --diagnose

The output includes:

Weight: total session size in bytes and message count
Tokens: exact token count (from usage data) or heuristic estimate
Context bar: visual bar showing % of the detected context window (200K or 1M)
Vital signs: progress ticks, file history snapshots, system reminders, thinking content, signatures, tool results
Message type breakdown: bytes per message type
Top 10 largest messages: biggest bloat contributors
Estimated savings by prescription: what gentle/standard/aggressive would save

Always surface the token count and context % to the user. If context is above 60%, suggest running /cozempic:treat with a prescription recommendation:

Under 5MB: gentle
5-20MB: standard
Over 20MB: aggressive

Skill Creator

by anthropics

vendor ×10

Create new skills, modify and improve existing skills, and measure skill performance.

Guide for creating effective skills. This skill should be used when users want to create a new skill (or update an existing skill) that extends Claude's capabilities with specialized knowledge, workflows, or tool integrations.

Replace with description of the skill and when Claude should use it.

by ZhanlinCui

×5

Use when facing 2+ independent tasks that can be worked on without shared state or sequential dependencies

This skill should be used when the user wants to "create a skill", "add a skill to plugin", "write a new skill", "improve skill description", "organize skill content", or needs guidance on skill structure, progressive disclosure, or skill development best practices for Claude Code plugins.

Helps users discover and install agent skills when they ask questions like "how do I do X", "find a skill for X", "is there a skill that can...", or express interest in extending capabilities. This skill should be used when the user is looking for functionality that might exist as an installable skill.

Use when creating new skills, editing existing skills, or verifying skills work before deployment

How to use it

Copy the folder

Take ruya-ai/diagnose from the repository into ~/.claude/skills for personal use, or into .claude/skills inside a project.

Check the name does not clash

The agent identifies a skill by the name field in its header. Two skills with the same name cannot sit side by side — one of them will be ignored.
