Effect v4
The CLI, @composio/cli-keyring, and @composio/json-schema-to-effect-schema run on
Effect v4. Every claim below is grounded in the migrated source, not memory of v3.
Version matrix
effect, @effect/platform-bun, and @effect/vitest
use the same range ^4.1.0; keep their lockfile resolutions aligned. Do not use
@next or mismatched versions across packages. @effect/cli and @effect/platform no longer exist as
dependencies; their surfaces are consolidated into effect and effect/*.
See versions.json for the exact example-check matrix (also typescript, vitest).
