| Every session | Name and description | 49 tok |
| When the agent uses it | The SKILL.md instructions | 283 tok |
| Only if opened | 2 bundled files (11 KB) | varies |
Until it is used, firebase-crashlytics costs about 28× 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
