≈35 tokens for metadata: the name and description. ≈631 when used: this file.

Description uses 1.8% of example budget

Before choosing a Skill, your Agent reads its name and description. All available Skills share that space.

  • A shorter description leaves more room for other Skills. This entry exceeds our 1% size suggestion.

In our Claude Code example, all Skill names and descriptions share 8,000 characters. This Skill uses ≈147 characters, or 1.8%.

The 1% threshold is a size suggestion. Longer descriptions can still fit.

Your model, settings, and other Skills decide how much text your Agent can read.

Example settings and source

The example uses a 200k-token context and default Claude Code settings. The count includes the name, description, separators, and when_to_use when present. Codex also counts local file paths.

Skit's source and limits: Codex 0.160.1, Claude Code 2.1.292.

Security Skill Best Practices

  1. Clear scope: Define what the skill does and doesn't do
  2. Legal warnings: Include responsible use disclaimers
  3. Tool requirements: List required external tools
  4. Safe defaults: Use non-destructive operations by default
  5. Logging: Include audit trail capabilities
