provides

provides

Legacy section. provides is the original input/output contract syntax with nested inputs and outputs blocks. It is still accepted by the parser for backward compatibility, but the canonical replacements are accepts (for inputs) and responds with (for outputs). Run mashin fmt to auto-migrate.

When to use

Do not use provides in new code. Use accepts and responds with instead.

The parser accepts provides with nested inputs and outputs blocks and will continue to do so during the migration period. If you encounter provides in existing .mashin files, either rewrite it manually or run mashin fmt to convert automatically.

Syntax (legacy)

provides
  inputs
    message as text, is required
    priority as text, default: "medium"
  outputs
    team as text
    confidence as decimal

Canonical replacement

accepts
  message as text, is required
  priority as text, default: "medium"

responds with
  team as text
  confidence as decimal

The canonical form is one nesting level flatter. accepts and responds with are top-level section verbs, while provides > inputs and provides > outputs required an extra level of indentation.

Migration

The mashin fmt formatter automatically converts:

// Before (legacy)
provides
  inputs
    name as text, is required
  outputs
    greeting as text

// After (canonical)
accepts
  name as text, is required

responds with
  greeting as text

Field declarations, types, and modifiers are preserved exactly. Only the section structure changes.
