Building Reliable Node API Boundaries
Structures Node.js API boundaries around explicit validation, authorization, atomic mutation, failure semantics, and request observability.
Primary benefit
Reduces trust-boundary mistakes and makes endpoint behavior easier to verify under retries and downstream failures.When to use
Use when implementing or reviewing Node.js API or service endpoints that cross trust or data boundaries and require explicit validation, authorization, failure semantics, observability, or retry behavior.
When not to use
Do not use for an internal pure function or a transport-free domain operation with no external trust boundary.
Use cases
Design a mutation endpoint with object-level authorization
Harden an existing Node.js handler against replay, malformed input, and downstream failure
Example prompts
Use building-reliable-node-api-boundaries to review this endpoint for validation, authorization, transaction, retry, and observability gaps.Install this skill
