`composio --version` goes from 288ms to 199ms, peak RSS from 97.8MB to 77.3MB, and the executable from 85.9MB to 79.7MB. Every command benefits. A compiled Bun binary parses its whole embedded bundle before the first line of JavaScript runs, and #4468 had already made sure the TypeScript compiler and the tokenizer rank table were never *evaluated* unless `generate`, `run`, or a large `execute` response needed them. They were still *parsed* on every start: the compiler alone was 44% of the executable's JavaScript and the o200k rank table another 28%, so `--version` spent ~75ms reading code it could never call. Both now ship as companion modules next to the executable, through the mechanism `composio run` already uses for its own runtime helpers: - `generation-runtime.mjs` carries `src/generation/*`, the `composio run` source rewrites, `typescript`, `@composio/ts-builders` and `openapi-typescript`. `generate ts`, `generate py` and `run` load it with `loadInstalledCompanionModule`; from a source checkout the loader resolves the `.ts` next to `run-companion-modules.ts` instead, so tests and `bun run src/bin.ts` need no build step. - `execute-output-encoder-runtime.mjs` carries `js-tiktoken/lite` and the rank table. `execute` loads it only once a response exceeds the 10KB byte pre-filter. A companion bundles its own copy of `effect`, and a fiber cannot run primitives built by another copy of the runtime, so nothing Effect-shaped crosses the boundary: the generation companion exposes plain functions and promises, runs its pipelines on its own runtime, and returns failures as values that `src/generation/errors.ts` rebuilds as the CLI's own error classes, stack included. Generated output is byte-identical to #4468 for `generate ts`, `generate ts --transpiled` and `generate py`. Both modules join `RUN_COMPANION_MODULE_BASENAMES`, so the build, release packaging, install verification, `upgrade` and the self-repair download pick them up unchanged. The three hand-maintained uninstall lists and the upgrade E2E fixture gain the two file names. Two smaller startup costs go with it: - `src/constants.ts` imported `constants` from `@composio/core`'s root entry for two strings and two URLs, which evaluated the whole SDK at startup (~25ms of module-scope work, mostly zod schemas). The four values are spelled out and pinned to core's by a test. - `tool-file-uploads.ts` imported three core helpers at module scope that only a file upload reaches; they are imported on that path now. The binary build gains a guard: after bundling the companions it bundles `src/bin.ts` once more unminified and fails if the executable's graph reaches `typescript`, `js-tiktoken`, core's root entry, `src/generation/*` or a companion entry. Without it a stray static import would put the compiler back into the executable with nothing to notice. Building also surfaced that `assertBundledRuntimeFiles` blanked string literals to same-length runs of spaces, which made the import patterns' `^\s*` backtrack quadratically across the compiler's multi-megabyte embedded lib strings and stalled the build for over ten minutes. String bodies are dropped now. (The check itself has never matched a specifier, since the specifiers it looks for are the string literals it removes; that is left as it was.) Measured on the pinned toolchain, Bun 1.4.1+4661e494f, linux-x64, best of 15, telemetry disabled, both binaries built in the same session: composio --version 288ms -> 199ms tools execute --help 287ms -> 202ms peak RSS 97.8MB -> 77.3MB executable 85.9MB -> 79.7MB executable JavaScript 8.3MB -> 2.1MB (minified) The `execute` tail after `execute.tool_call.end` is unchanged for responses under 10KB (~10ms) and ~20ms slower above it (351 -> 374ms), which is the on-demand parse of the 2.2MB encoder companion.

Composio CLI installation
Install the CLI bundle in ~/.composio and its entry point in ~/.local/bin:
curl -fsSL https://composio.dev/install | sh
The installer also configures your shell. It infers your login shell from $SHELL (zsh, bash, or fish) and writes a managed # Composio CLI PATH block so future terminals find composio. For zsh and fish, it updates the matching startup file. For bash, it updates ~/.bashrc plus a login-mode startup file, because a login bash (what macOS Terminal.app starts) never reads ~/.bashrc: the first existing of ~/.bash_profile or ~/.bash_login, or a newly created ~/.bash_profile when neither exists. A ~/.bash_profile created this way sources ~/.profile first, so nothing you already had stops loading; ~/.profile itself is never modified. Open a new terminal, then run composio login.
If your shell is not recognized, or shell setup fails, the binary install still succeeds and the installer prints a runnable command instead. The installer does not install agent plugins or log you in unless you ask it to.
Official releases must pass SHA-256 verification against the release's checksums.txt: a missing manifest, a manifest with no entry for your platform's archive, a malformed entry, or a mismatch aborts the install with Refusing to install. On systems with no sha256sum or shasum, the installer warns that verification was skipped and continues.
Choose or skip shell setup
Set COMPOSIO_INSTALL_SHELL to force a specific shell, or to skip shell configuration entirely:
curl -fsSL https://composio.dev/install | COMPOSIO_INSTALL_SHELL=zsh sh
curl -fsSL https://composio.dev/install | COMPOSIO_INSTALL_SHELL=bash sh
curl -fsSL https://composio.dev/install | COMPOSIO_INSTALL_SHELL=fish sh
curl -fsSL https://composio.dev/install | COMPOSIO_INSTALL_SHELL=none sh
Use none for an install-only run that changes no shell files. Reach for it in CI, Docker images, or when a dotfile manager owns your startup files.
Shell-specific installer variants (install/zsh.sh, install/bash.sh, install/fish.sh) pin COMPOSIO_INSTALL_SHELL to their shell before delegating to the base installer.
Shell setup is idempotent: repeated installs keep exactly one managed PATH block per startup file and reconcile it when the bin directory changes. Setup delegates to composio install --shell <shell> and falls back to writing the same # Composio CLI PATH block inline when the installed CLI predates that flag, delegated setup fails, or delegated setup leaves a stale block.
Pin a stable or beta release with COMPOSIO_INSTALL_VERSION, or pass the tag as a positional argument:
curl -fsSL https://composio.dev/install | COMPOSIO_INSTALL_VERSION=0.3.1 sh
curl -fsSL https://composio.dev/install | sh -s -- @composio/cli@0.3.1-beta.329
The positional argument takes precedence over COMPOSIO_INSTALL_VERSION.

Remove the managed # Composio CLI PATH block from ~/.zshrc, ~/.bashrc, ~/.bash_profile, ~/.bash_login, or ~/.config/fish/config.fish. Blocks written by older installers contain an extra export COMPOSIO_INSTALL_DIR=... (or set --export COMPOSIO_INSTALL_DIR ...) line after the marker; remove that line too. If removing the block leaves ~/.bash_profile with nothing but blank lines, delete the file: the installer creates it on bash systems that had no login startup file, and even an empty ~/.bash_profile keeps bash from reading ~/.profile. If you had a ~/.profile at install time, that created file instead holds a passthrough sourcing it, starts with # Created by the Composio CLI installer., and is left in place; delete it as well to restore bash's default startup-file selection.
To purge credentials, configuration, caches, and every other CLI file, run rm -rf "${COMPOSIO_INSTALL_DIR:-$HOME/.composio}". This is a complete reset and cannot be undone.
