## Summary `composio execute` made eight backend requests. Two of them were the same list of the user's connected accounts, fetched by two code paths that cannot see each other. It is fetched once now. Interleaved A/B against #4469, compiled binaries, 15 runs each on a small response: 1735ms to 1636ms best, 1934ms to 1845ms median. That is one round trip (~140ms) off the critical path. Results are identical to before in every case. The picker derives its toolkit subset from the shared list with the exact semantics of its old query, and falls back to that query when the shared list is truncated. Fifth PR in the stack. Stacked on #4469; review #4463, #4464, #4468 and #4469 first. #4483 builds on this one. ## Changes 1. `src/utils/memoize-in-process.ts` (new). Memoizes an Effect per key for the process lifetime, shares one run between concurrent callers, and drops a failure, defect or interruption so the next caller retries. 2. `listActiveConnectedAccounts` in `connected-account-selection.ts`: the unfiltered `GET /connected_accounts` for a user, memoized by client identity and user id. It fails with the raw rejection, and each caller wraps that in its own error. `resolveToolRouterSessionConnections` reads from it when it has no toolkit filter, which is the execute path. With a filter it keeps its own request. 3. `resolveConnectedAccountForToolkit` used to issue its own request, toolkit-filtered, `limit: 100`. It now derives that from the shared list: same slug match, server order preserved, first 100. If the shared list has a `next_cursor` or `total_items` above what it holds, the toolkit's accounts may sit past the cut, so the original filtered request runs instead. 4. `get_latest_version` goes through the same memo. The definition refresh fetched it twice with identical headers on the stale path; that is one request now. The executor's own version lookup sends no org or project headers and stays a separate request. Scoping it would change which definition it resolves under, which is a semantics decision, not a perf one. What does not change: the request list on a normal execute is now `project/resolve`, `connected_accounts`, `get_latest_version` twice, `consumer/config`, `session`, `execute`. Error messages are unchanged; the fallback passes the raw rejection through so the picker's message reads as before. ## Type of change - [ ] Bug fix - [ ] New feature - [x] Refactor/Chore - [ ] Documentation - [ ] Breaking change ## How Has This Been Tested? Bun 1.4.1+4661e494f, Node 24.20.0, pnpm 11.8.0, linux-x64. 1. `cd ts/packages/cli && pnpm run typecheck && pnpm run validate:boundaries` 2. `pnpm exec vitest run`: 131 files, 1341 passed, 1 skipped (whole stack). New tests cover the memo sharing one run per key and retrying after a failure or a defect. The execute suite already covers account selection with and without a selector and passes unchanged. The test layer builds a fresh client per test, so the client-keyed memo does not bleed between tests. 3. Request count: hooked `fetch` while running `execute HACKERNEWS_GET_ITEM_WITH_ID` from source. `connected_accounts` appears once, the rest of the list as before. 4. Timing: `pnpm build:binary`, then the interleaved A/B above against #4469's binary. A second round of 12 gave 1788 to 1621ms best, 2045 to 1963ms median. ## Screenshots (if applicable) Not applicable. ## Checklist - [x] I have read the Code of Conduct and this PR adheres to it - [x] I ran linters/tests locally and they passed - [ ] I updated documentation as needed - [x] I added tests or explain why not applicable - [ ] I added a changeset if this change affects published packages No docs describe the request sequence. `@composio/cli` is private, so no changeset. ## Additional context The rest of an execute, from the same trace: `project/resolve` 140 to 640ms with no cache, `tool_router/session` 385 to 655ms created per invocation, and the execute call itself 500 to 730ms. The connected-account cache in `consumer-short-term-cache.ts` would take `connected_accounts` off the path entirely, but `DISABLE_CONNECTED_ACCOUNT_CACHE` defaults to on, and enabling it fails no-auth toolkits with "not connected" because the cached list does not include them. Both are separate changes. 🤖 Generated with [Claude Code](https://claude.com/claude-code) https://claude.ai/code/session_01Wx9gEjuiHux2weiHjdNcDs

Composio
Composio gives your AI agents 1000+ pre-authenticated toolkits, per-user sessions, authentication, triggers, and a sandbox, so you can ship agents that turn intent into action.
This is the Composio SDK monorepo. It contains:
@composio/core: TypeScript SDKcomposio: Python SDKcomposioCLI: search, execute, and script tools from your shell- Provider adapters for OpenAI Agents, Claude Agent SDK, Vercel AI SDK, LangChain, and more
Quickstart
Create a session for a user, hand its tools to your agent, and let the agent take action across 1000+ apps. Grab a COMPOSIO_API_KEY from the dashboard first.
TypeScript
npm install @composio/core @composio/openai-agents @openai/agents
@composio/coreintentionally packages its TypeScript source and SDK docs so the installed package is inspectable to coding agents. If you want a smaller install with the same API, use@composio/slim.
import { Composio } from "@composio/core";
import { OpenAIAgentsProvider } from "@composio/openai-agents";
import { Agent, run } from "@openai/agents";
const composio = new Composio({ provider: new OpenAIAgentsProvider() });
// Each session is scoped to one of your users
const session = await composio.create("user_123");
const tools = await session.tools();
const agent = new Agent({
name: "Personal Assistant",
instructions: "You are a helpful assistant. Use Composio tools to take action.",
tools,
});
const result = await run(agent, "Summarize my emails from today");
console.log(result.finalOutput);
Python
pip install composio composio-openai-agents openai-agents
from composio import Composio
from composio_openai_agents import OpenAIAgentsProvider
from agents import Agent, Runner
composio = Composio(provider=OpenAIAgentsProvider())
# Each session is scoped to one of your users
session = composio.create(user_id="user_123")
tools = session.tools()
agent = Agent(
name="Personal Assistant",
instructions="You are a helpful assistant. Use Composio tools to take action.",
tools=tools,
)
result = Runner.run_sync(starting_agent=agent, input="Summarize my emails from today")
print(result.final_output)
By default a session gets meta tools that discover, authenticate, and execute app tools at runtime, so you don't load hundreds of tool definitions into context. Store session.session_id and reuse it with composio.use() across turns. See what a session is and configuring sessions for restricting toolkits, auth configs, and connected accounts.
Prefer MCP? Every session also exposes a hosted MCP endpoint. Pass mcp: true to composio.create() and point Claude, Cursor, or any MCP client at session.mcp.url. See sessions via MCP.
CLI
The composio CLI runs Composio from your shell and gives coding agents like Claude Code a local tool surface.
curl -fsSL https://composio.dev/install | sh
The installer puts composio on your PATH for future terminals. Open a new terminal, then run composio login. See INSTALL.md for shell setup overrides, including COMPOSIO_INSTALL_SHELL=none for install-only runs.
Use composio search to find tools, composio execute to run them, composio link to connect accounts, and composio run to script workflows in TypeScript. See the CLI docs.

A provider adapts Composio tools to your agent framework's native tool format:
