@async/cli

@async/cli

Filesystem-routed commands for local projects and user-global tools.

@async/cli treats command directories as the CLI surface. A command such as:

cli gh pull

maps to a command directory like:

.cli/gh/pull/script.ts

The contract is defined in SPEC.md. The package implements local and user-global command discovery, command resolution, script execution with a trust model for local overlays, machine-readable listing, --which, command scaffolding with templates, command copy/move/remove, --edit, command packs via --add, shell completions, a tree doctor, an MCP server mode, context-file pointers, help, and version output.

Install

pnpm add -D @async/cli

Binaries

The package declares two equivalent binaries:

cli
async-cli

Command Roots

cli discovers local .cli/ overlays from the current working directory upward to the nearest Git root, then appends the user-global command tree. Use ASYNC_CLI_GLOBAL_ROOT to replace the user-global tree and ASYNC_CLI_PROJECT_ROOT to pin project-root behavior in tests or controlled launchers.

Built-Ins

cli help
cli help gh
cli --list
cli --list --json
cli --which gh pull
cli --new gh pr
cli --new gh pr --root
cli --new gh pr --template worker
cli --edit gh pull
cli --rm gh pull
cli --cp gh pull
cli --cp gh pull --to local
cli --mv gh pull
cli --mv gh pull --to local
cli --add https://example.com/org/pack.git
cli --trust
cli --trust --status
cli --untrust
cli --doctor
cli --completions bash
cli --mcp
cli --agents
cli --agents --write
cli --agents --check
cli --agents --claude --write
cli --version

Command scripts run from the caller's original working directory by default; a // cli-cwd: project-root or // cli-cwd: script-dir head comment changes that per script. .js and .mjs scripts run directly with Node; .ts and .mts scripts use Node 24 native type stripping.

Use --cp to clone a command directory between local and user-global command trees without removing the source. Use --mv when the source should be transferred instead, and --rm to delete a command directory.

Trust

Repo-local .cli/ overlays are refused at execution time until you trust them, because cloned repositories can shadow your user-global commands:

cli --trust           # trust the local overlays discovered from here
cli --trust --status  # trusted | changed | untrusted per overlay
cli --untrust         # revoke

Trust records a content hash of the overlay; any change requires re-trusting. Listing and --which never require trust. Set ASYNC_CLI_TRUST=off to disable enforcement in controlled environments.

Completions

eval "$(cli --completions bash)"   # or zsh
cli --completions fish | source    # fish

Doctor

cli --doctor [--json] audits every command root: ambiguous script directories, ../ imports that break --cp/--mv, empty command directories, untrusted overlays, missing descriptions, shadowed commands, and stale --agents pointer blocks.

MCP

cli --mcp serves the command tree as MCP tools over stdio (JSON-RPC 2.0, zero dependencies), so agent runtimes can discover and call the same commands humans use. Untrusted local overlays are excluded.

Packs

Install commands from any Git repository that carries a .cli/ tree:

cli --add https://example.com/org/pack.git             # into ~/.cli
cli --add https://example.com/org/pack.git --prefix vendor
cli --add https://example.com/org/pack.git --to local  # into this repo

Development

pnpm run build
pnpm test
pnpm run pack:check
pnpm run release:check

Maintainers who want the shell to prefer this checkout over an npm-installed copy can link the local binaries:

pnpm run local:link
pnpm run local:status
pnpm run local:unlink
