fix(eve): drop contradictory OpenAPI schema annotations by vercel-gh-bot-2[bot] · Pull Request #2370 · vercel/eve

vercel-gh-bot-2 · 2026-08-21T08:05:39Z

OpenAPI connections now remove default and example values that disagree with the schema's effective JSON type. This stops model-facing tool schemas from recommending input that eve's local validator rejects.

Motivation

Published OpenAPI specs can contradict themselves. For example, Xero declares boolean request fields with default: "false" and example: "false". On main, the generated tool schema preserves both strings, so a model can submit a string where the generated validator requires a boolean.

A focused regression reproduced this before the fix:

Expected: { type: "boolean" }
Received: { type: "boolean", default: "false", example: "false" }

Fixes #2369

Hypothesis

Because derefSchema already normalizes JSON Schema types and OpenAPI nullability, checking annotations after those passes should remove only contradictory values. Matching values, nullable values, and annotations on untyped schemas should remain unchanged.

The dereferencer now treats annotation values as opaque data rather than nested schemas. This preserves object-valued defaults and examples while validating their outer JSON type.

Verification

pnpm --filter eve exec vitest run --config vitest.unit.config.ts src/runtime/connections/openapi-client.test.ts passed all 36 tests
pnpm --filter eve typecheck passed
oxfmt --check and oxlint passed on changed files
The full eve unit suite passed 6,976 of 6,981 tests. Four unrelated tests failed under full-suite load, and all 98 tests in those three files passed when run together in isolation
Correctness re-review passed after adding coverage for opaque object-valued annotations

Package Details

Package: eve@0.42.0
Package directory: packages/eve
Tarball: 8.17 MB (eve-0.42.0.tgz)
Unpacked payload: 30.74 MB across 3386 published files
Installed footprint: 74.82 MB across 7097 installed files
Installed root package: 29.38 MB
Installed dependencies: 45.44 MB
Installed package instances: 35
Distinct installed package names: 34
Installed dependency edges: 53
Installed optional peer edges: 47
Runtime dependencies: 2
Peer dependencies: 5 (4 optional)

Installed footprint is measured from an isolated temporary npm install of the packed tarball.
Graph metrics read only package.json files in package directories directly beneath a node_modules boundary, including nested boundaries. Each directory is one package instance; distinct names come from those manifests. Dependency edges count each unique name in dependencies or optionalDependencies per instance; optional peer edges count peerDependencies marked optional.

This is an informational timing measurement inside eve build, from preflight through publication. Output-size measurement and profile writing are excluded.

Build mode: deployable Vercel build with sandbox template prewarm included.

Build pipeline: 2.30 s -> 2.20 s (-100.1 ms) vs main (f3f4f4a).
Timing is informational: shared GitHub runners are too variable for a hard timing budget.
