Creating MCP Code Mode Skills
This skill teaches how to author agent skills, not how to prompt models. You are designing deterministic scaffolding for a probabilistic system. Assume the model is capable. Favor constraints, structure, and files over prose.
Mental Model
The model reasons.
Code executes.
The filesystem remembers.
A Code Mode MCP skill is a closed-loop control system, not a function call.
- Reasoning lives in the model
- Work happens in code
- Truth persists on disk
If information is large, fragile, repetitive, or stateful, it does not belong in the context window.
