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 | 73 tok |
| When the agent uses it | The SKILL.md instructions | 1,946 tok |
| Only if opened | 16 bundled files (114 KB) | varies |
Until it is used, firebase-data-connect costs about 19× less than the median MCP server we measured (1,362 tokens on every turn). Installing all 13 skills from firebase/agent-skills would load 1,052 tokens of descriptions. Skills vs MCP study
