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	52 tok
When the agent uses it	The SKILL.md instructions	117 tok
Only if opened	163 bundled files (28.7 MB)	varies

Until it is used, fast-agent-design costs about 26× less than the median MCP server we measured (1,363 tokens on every turn). Installing all 3 skills from evalstate/fast-agent would load 184 tokens of descriptions. Skills vs MCP study
