Alberto Schiabel 6d5465acd3 refactor(cli): seal the CommandDescriptor seam and drop zod for Schema (#3882)
This PR:
- activates the descriptor-seam rule group:
`commands/command-introspection.ts` becomes the only module allowed to
import `CommandDescriptor`/`Usage` from `@effect/cli` — the redesign
seam the Effect CLI v4 migration will reimplement
- routes root command assembly, preflight parsing, help routing, and
value-option collection through the seam helpers instead of descriptor
walks
- replaces the Zod-backed tool-input adapter with an internal
`@composio/json-schema-to-effect-schema` compiler backed by the
eval-free `@cfworker/json-schema` interpreter
- normalizes the OpenAPI and Composio extensions accepted by the
previous validator, while preserving typed `ToolInputValidationError`
failures, field paths, multi-error reporting, and typo suggestions
- extends the descriptor and Zod boundaries to reject static imports,
dynamic `import()`, and `require()` bypasses
- adds compiler parity tests plus CLI regression coverage for multiple
simultaneous field and unknown-key failures
- introspection tests pin that the helpers yield identical descriptors
and usage strings

Composio TypeScript workspace

This directory contains the TypeScript half of the Composio SDK monorepo: the core SDK, provider adapters, the CLI, examples, and end-to-end tests. For an overview of Composio itself, start at the root README and docs.composio.dev.

If you just want to use the SDK:

npm install @composio/core
import { Composio } from '@composio/core';

const composio = new Composio({ apiKey: process.env.COMPOSIO_API_KEY });

const session = await composio.create('user_123');
const tools = await session.tools();

See the @composio/core README and the quickstart for the full flow, including provider setup for your agent framework.

Packages

Published packages:

Package Description
@composio/core The Composio SDK. Ships its TypeScript source and SDK docs so installed copies are inspectable by coding agents.
@composio/slim Same API as @composio/core without the packaged source and docs; smaller install.
composio CLI Standalone CLI binary: search, execute, and script tools from your shell.
@composio/* providers Adapters that format Composio tools for agent frameworks (OpenAI, Anthropic, Vercel AI SDK, LangChain, and more). See the provider table.
@composio/experimental Experimental integrations, currently the Pi provider.
@composio/json-schema-to-zod JSON Schema to Zod conversion.

Internal (unpublished) packages: cli-keyring and cli-local-tools support the CLI; ts-builders generates TypeScript source.

Development

Commands run from the repository root. Install the pinned toolchain first:

mise install
pnpm install

Build and verify:

pnpm build:packages   # build all TS packages
pnpm typecheck        # typecheck all TS packages
pnpm lint:packages    # eslint over ts/packages
pnpm test             # package unit tests plus example validation

Runtime E2E suites (require credentials):

pnpm test:e2e:node
pnpm test:e2e:deno
pnpm test:e2e:cloudflare
pnpm test:e2e:cli

Scaffolding:

pnpm create:provider <name> [--agentic]   # new provider package
pnpm create:example <name>                # new example under ts/examples

Changesets are required for changes to published packages; see the contribution guidelines.
