What it does

The base44 CLI is used for EVERYTHING related to base44 projects: resource configuration (entities, backend functions, realtime actors, ai agents), initialization and actions (resource creation, deployment). This skill is the place for learning about how to configure resources, including actors — the realtime/WebSocket primitive behind multiplayer, collaborative boards, presence and live cursors, in-room chat, and live auctions. When you plan or implement a feature, you must learn this skill

What this skill changes about the agent has not been set out here as a list. Its SKILL.md, shown below, says it in the author’s own words.

The skill itself

A skill is instructions the model reads, so you can see what you are getting: below is the start of its SKILL.md. The front matter loads with every session, the body loads when the skill triggers, and the whole file comes with the install.

12Create and manage Base44 apps (projects) using the Base44 CLI tool.
13
14## ⚡ IMMEDIATE ACTION REQUIRED - Read This First
15
16This skill activates on ANY mention of "base44" or when a base44/ folder exists. **DO NOT read documentation files or search the web before acting.**
17
18**Your first action MUST be:**
191. Check if base44/config.jsonc exists in the current directory
202. If **YES** (existing project scenario):
21 - Transfer to base44-sdk skill for implementation
22 - This skill only handles CLI commands (login, deploy, entities push)
23 - **Except running the app locally** — stays here. Read [Running Local Development](#running-local-development)
24 before starting a dev server: one way of running hits production data.
253. If **NO**, decide between two initialization paths:
26 - **Provisioned app** — the Base44 app already exists because it was just provisioned through a Stripe Projects / projects.dev flow, OR BASE44_APP_ID (or BASE44_PROJECTS_BASE44_APP_ID) is present in the environment or a .env/.env.local file:
27 - Run npx base44 scaffold to set up local files for that **existing** app
28 - **DO NOT run npx base44 create** — that creates a second, duplicate app. See [scaffold.md](references/scaffold.md).

Why you can read it

Nothing in a skill executes. The client loads the text and the model follows it, so a skill can be audited the way a runbook is — by reading it.

What it costs in context

Skills are not billed by the call. They are paid for in context: every token the instructions occupy is a token your code, your diff and your conversation cannot use. Here is what this one takes and when it takes it.

39.6k tokens, estimated from the bundle at four bytes to the token, held for the rest of the session once it triggers. Heavy. Teams tend to install this one per project rather than globally, and load it only when the job comes up.

Servers bill, skills cost

A server charges by the month. A skill charges once per session, in context, and then keeps charging it for as long as the session lives.

Before and after

The same question, put to the same model twice: once as it comes, and once with these instructions loaded.

No worked example has been published for this skill yet.

The procedure it runs

The procedure has not been set out here step by step. It is in the body of its SKILL.md: the start of it is shown above, and the whole file comes with the install.

Prose, not code

These steps are written for a model to follow, not executed by a runtime. It can still be told to skip one, and it will say so when it does.

Servers it uses

None. This skill calls no MCP servers at all.

Everything it needs is in the instructions, so it works in a project with nothing connected — the model reads the file and changes how it works with what it can already reach.

Its SKILL.md does not declare which tools it asks the agent for, so what it touches is whatever the instructions themselves ask for — read them before you install it.

What it asks for
Writes filesnot declared
Network accessnot declared

This SKILL.md carries no allowed-tools line, so neither is declared. A skill grants no permissions of its own — it can only ask for tools your client already has.

What it will not do

Every skill is narrow, and the useful ones say where they stop. These are the jobs this one is the wrong tool for.

What this skill is not for has not been published here. Nothing is implied by that: it is a section the author has not filled in.

What is in the bundle

37 files, 158.3 kB on disk. A bundle is text throughout: the instructions the model reads, plus the templates it fills in.

What is not in it

No dependencies and nothing executable: a skill is text the agent reads, so the bundle is 37 files you can review in full before installing. The MIT licence covers the templates and examples as well as the instructions.

Install

Installing copies the bundle into your project. Nothing runs at install time — the files sit on disk until the model reads them.

# Base44 CLI · 39.6k tokens when loaded · macOS, Linux mkdir -p .claude/skills && t=$(mktemp -d) && curl -fsSL -o "$t/bundle.tar.gz" https://mcprush.com/api/skills/base44-cli/bundle.tar.gz && tar -xzf "$t/bundle.tar.gz" -C "$t" && [ -d "$t/base44-cli" ] && { [ ! -e .claude/skills/base44-cli ] || { mv .claude/skills/base44-cli "$t/.previous" && echo "Previous copy moved to $t/.previous"; }; } && mv "$t/base44-cli" .claude/skills/ && echo "Installed .claude/skills/base44-cli"

npx mcprush@latest skill add base44/base44-cli

Windows PowerShell says 'running scripts is disabled on this system'? Run Set-ExecutionPolicy -Scope CurrentUser RemoteSigned once, or type npx.cmd instead of npx (codex.cmd, gemini.cmd, grok.cmd likewise). PowerShell 7 needs neither. Writes to .claude/skills/base44-cli/ in the current project. For every project instead, run mkdir -p ~/.claude/skills && t=$(mktemp -d) && curl -fsSL -o "$t/bundle.tar.gz" https://mcprush.com/api/skills/base44-cli/bundle.tar.gz && tar -xzf "$t/bundle.tar.gz" -C "$t" && [ -d "$t/base44-cli" ] && { [ ! -e ~/.claude/skills/base44-cli ] || { mv ~/.claude/skills/base44-cli "$t/.previous" && echo "Previous copy moved to $t/.previous"; }; } && mv "$t/base44-cli" ~/.claude/skills/ && echo "Installed ~/.claude/skills/base44-cli" (macOS, Linux) — or add --global to the npx line. The curl line replaces .claude/skills/base44-cli/ only after the download succeeds, so files left there by another skill of the same name, or by an older release, do not mix in. A copy already there is moved aside, not deleted, and the line prints where.

Which clients pick it up on their own

A skill is a folder of text. Most of these read a skills folder and pick it up without being told; the rest take the same folder another way — an upload in the app, a parameter on an API call — and then choose it by its description just the same.

Versions

v0.1.7 is what is on the shelf; no release here carries a date. Instructions change more often than APIs do — a skill can be rewritten entirely without anything it depends on moving.

v0.1.7
  • No earlier releases have been published to the marketplace.
Pinning

The install command always fetches the release that is current the day you run it — v0.1.7 today — and cannot ask for an earlier one. The copy on your disk does not change until you run it again.
