Effect v4
The CLI, @composio/cli-keyring, and @composio/json-schema-to-effect-schema run on
Effect v4 (release candidate). Every claim below is grounded in the migrated source, not memory of v3.
Exact version matrix
effect, @effect/platform-bun, and @effect/vitest
are pinned to the same exact 4.0.0-rc.115 — never ^, @next, or a mismatched
prerelease across packages. @effect/cli and @effect/platform no longer exist as
dependencies; their surfaces are consolidated into effect and effect/unstable/*.
See versions.json for the full matrix (also typescript, vitest).
