Contract icons

The 11 contract icons, described

An API — the interface one program offers another, its endpoints and its contract.

Data contract breakdata-contract-break

A document split by a crack — a data contract broken by an upstream change.

An expectation — the rule the data has to keep, a contract asserted on every load.

Two equal lines held between brackets — an invariant that must stay true throughout.

MCP tool schemamcp-tool-schema

An MCP tool schema — the JSON contract that says what arguments a tool takes.

Postconditionpostcondition

A check placed after the block — a postcondition that must hold once code has run.

Preconditionprecondition

A check placed before the block — a precondition that must hold before code runs.

Schema pinschema-pin

Schema pin — the columns held still on purpose, a frozen contract.

Schema registryschema-registry

A schema registry — every version of every schema, kept where producers can check it.

SLAsla

An SLA — the service level agreement, a promise with a signature on it.

In code, each is one import — import { AgentProtocol } from "@iconmind/react/icons/agent-protocol" — and the same name in Vue, Svelte, Solid, Preact, React Native, Astro, Blade and Flutter.
