Recommit "feat(eve): mount bundled development extensions" by prha · Pull Request #3658 · vercel/eve

prha · 2026-09-22T23:04:20Z

Summary

This is a recommit #3541, which was reverted. The fix for the dev dependency resolution was merged in #3641 (marking just-bash optional deps to be ignored).

Local development should expose eve's self-modification capabilities without requiring every project to install an extension mount first. This change makes eve dev mount bundled development extensions by default, initially self-modification, while letting an authored
self-modification mount take precedence and providing --no-default-extensions to disable the defaults. The selection persists across local server processes and rebuilds, while production bundles do not initialize development-only mounts.

Validation

pnpm --filter eve exec vitest run --config vitest.unit.config.ts src/compiler/source-graph.test.ts src/discover/bundled-extension.test.ts src/self-modification/extension/subagents/agent/instructions.test.ts src/cli/run.test.ts (78 tests passed)
pnpm --filter eve exec vitest run --config vitest.integration.config.ts src/compiler/development-extensions.integration.test.ts (2 tests passed)
git diff --check

Package Drill-Down

Package Details

Package: eve@0.64.1
Package directory: packages/eve
Tarball: 8.60 MB (eve-0.64.1.tgz)
Unpacked payload: 32.02 MB across 3785 published files
Installed footprint: 78.25 MB across 7748 installed files
Installed root package: 31.37 MB
Installed dependencies: 46.88 MB
Installed package instances: 33
Distinct installed package names: 32
Installed dependency edges: 51
Installed optional peer edges: 9
Runtime dependencies: 2
Peer dependencies: 7 (6 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: 3.83 s -> 3.98 s (+147.5 ms) vs main (d2ed49e).
Timing is informational: shared GitHub runners are too variable for a hard timing budget.
