Custom skills

Write a SKILL.md and it becomes part of an agent's brain.

Built-in vs custom

Built-in skills (trading, token-launch, portfolio, market-intelligence, social, sniper, wallet, image-generation) gate which tools an agent gets. Custom skills are standing instructions: when an agent's skills array contains your slug, the skill's content is injected into its system prompt.

Your own skill wins if its slug collides with a public one. Make a skill public to share it in the registry.
