create skill
What it does
- 85% reduction in initial context load
- Activation times drop from 500ms+ to under 100ms
- Agent loads only what's needed, when it's needed
- Skills remain maintainable and focused
- Does the agent really need this explanation?
- Can I assume the agent knows this?
- Does this paragraph justify its token cost?
Requirements & configuration
- The 200-line rule is critical. SKILL.md must be under 200 lines. If you need more, split content into references/ files.
- The context window is a shared resource. Your skill shares it with everything else the agent needs. Be concise and challenge each piece of information:
- Does the agent really need this explanation?
- Does this paragraph justify its token cost?
- Skills act as additions to models, so effectiveness depends on the underlying model. Test your skill with all models you plan to use it with.
