Skills

Skills are markdown files that teach the agent specific capabilities — a workflow, a domain, a set of best practices. They load on-demand when relevant to the conversation, keeping context lean when they're not needed.

Open Agent Capabilities → Skills. You can:

• View every installed skill's name and description
• Toggle skills between always-on (loaded every session) and on-demand (loaded when relevant)
• Edit skill content inline
• Add new skills

Skills are plain markdown files. Edit them with any editor — changes take effect on the next agent invocation (no restart needed). They live under ~/.kiro/crew/skills/.

• Always-on skills — full content injected into every session
• On-demand skills — loaded only when your message matches the skill's trigger keywords

You don't need to tell the agent to use a skill. If you mention something that matches a skill's triggers, it loads automatically.

Crew ships with skills for common workflows:

• kirocrew-commands — reference for CLI subcommands and MCP tools
• security-assistance — safe-by-default patterns for security-adjacent code
• prepare-pr — pre-review build + test + description formatting
• artifacts — creating and iterating on persistent artifacts
• widgets — building interactive mcwidgets

Additional skills are available and visible in the Skills panel.

For power users who want to teach the agent something custom. Create a file at ~/.kiro/crew/skills/my-skill/SKILL.md:

---
name: my-skill
description: Explains how to do X in our codebase.
triggers: [deploy, release, ship]
always: false
---

# My skill

When the user asks about deploying:

1. Run the test suite first
2. Check the staging environment
3. Use the deploy script at scripts/deploy.sh

The triggers field lists keywords — when any appear in your message, the skill loads for that turn.
