jkomyno 4a764c100a perf(cli): fetch the toolkit catalog once per process
A single command can ask for the full toolkit list several times —
toolkit resolution, validation, telemetry — and the file cache only
answers when FORCE_USE_CACHE is set, so the default path paid for the
same ~800 KB two-page download up to four times.

Memoize the lookup for the lifetime of the cached repository layer. The
first caller pays and the rest await the same result. Effect.cached
memoizes the outcome rather than only the success, so a failed fetch
stays failed for the process: the right trade for a one-shot CLI, where
retrying a broken network per call only multiplies the wait before the
same error surfaces.

That surfaced a second doubling underneath. The caching helper wrapped
its whole body — cache lookup and the underlying request alike — in one
catchAll that fell back to re-running the request, so a request that
failed on its own was immediately sent again and failed the same way.
Cache concerns now degrade to a miss on their own, and the request runs
exactly once with its failure passed straight through.

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Internal (unpublished) packages: cli-keyring and cli-local-tools support the CLI; ts-builders generates TypeScript source.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