The model sees only what you wrote: a name, a description and a schema. Everything else it guesses.
What you get
- Three rules that make a tool description something a model can act on
- A ban list for vague verbs, and a policy of no delete tools
- One registry that declares each operation once and derives REST, OpenAPI, MCP and CLI
- Parity tests that prove the four never disagree
- The runbook for the day a tool is called wrongly
How it is written
Every chapter opens with how it breaks and ends with the one decision that stays with a person.
Who it is for
Builders who expose tools to a model and want fewer wrong calls.
