Package Details
- Package:
eve@0.43.0 - Package directory:
packages/eve - Tarball: 8.18 MB (
eve-0.43.0.tgz) - Unpacked payload: 30.78 MB across 3402 published files
- Installed footprint: 74.86 MB across 7113 installed files
- Installed root package: 29.42 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.

}Build Timing: e2e/fixtures/agent-tools-sandbox
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: 2.48 s -> 2.30 s (-178.5 ms) vs
main (4da95bb). - Timing is informational: shared GitHub runners are too variable for a hard timing budget.

Dynamic tools with destructured defaults can fail during
eve build. The durable callback transform reused the authored binding pattern as a call argument, so a valid parameter such as{ dryRun = false }became an invalid object literal.The transform also rebuilt callback inputs from their bindings. That could discard input shape before the hoisted callback received it.
The hypothesis is that forwarding the wrapper's original arguments leaves parameter semantics with the hoisted authored callback. This keeps the full input object, applies defaults once, and preserves context arguments. Generator wrappers return the hoisted iterator directly so parameter initialization still happens when the callback is invoked.
Regression coverage exercises defaulted and nested destructuring, rest properties, context forwarding, generator invocation timing, and async generator output shape. This includes the syntax that previously produced
Invalid assignment in object literal.Validation:
pnpm --filter eve exec vitest run --config vitest.unit.config.ts src/internal/workflow-bundle/dynamic-tool-transform.test.ts(67 passed)pnpm --filter eve typecheckpnpm --filter eve buildpnpm lint && pnpm guard:invariantsgit diff --checkThe full unit run passed 7,012 tests and hit two unrelated five-second timeouts. Both timed-out files passed on an isolated rerun, 36/36.
