What it costs your context
Agent Skills load in three steps. Tokens counted with the o200k tokenizer; your model's count will differ a little.
| When | What loads | Cost |
|---|---|---|
| Every session | Name and description | 28 tok |
| When the agent uses it | The SKILL.md instructions | 3,798 tok |
| Only if opened | 4 bundled files (31 KB) | varies |
Until it is used, skill-creator costs about 49× less than the median MCP server we measured (1,363 tokens on every turn). Installing all 10 skills from RKiding/Awesome-finance-skills would load 393 tokens of descriptions. Skills vs MCP study
