At a glance

Gets Firecrawl working in a project: signs you in through the browser, saves FIRECRAWL_API_KEY to .env and picks the first SDK or REST path.

  • Works in 8 steps: decide whether this is a fresh project… → ask what Firecrawl should do in the… → pick the narrowest endpoint that matches… → …
  • Adding Firecrawl to an application for the first time
  • SKILL.md covers Install, Use This When, Quick Start and What Do You Need?, plus 2 more sections
  • Calls stripe and npx; needs FIRECRAWL_API_KEY and FIRECRAWL_API_API_KEY

What it does

This companion to the Firecrawl build skills covers the setup step for application code. A single install command adds the Firecrawl CLI, the CLI skills and the build skills, and opens a browser sign-in so you can log in or create an account. If you already have a key it goes into .env, and self-hosted deployments also set FIRECRAWL_API_URL.

Projects that already use Stripe Projects can pull the key from there instead, and the skill notes a naming detail: the key only lands in FIRECRAWL_API_KEY when the name flag is set, and the extra base URL variable the CLI writes should be ignored for hosted accounts. Upgrading to a paid plan is left to you because it charges your card. After setup, the agent integrates Firecrawl into a fresh or existing project and runs a smoke test.

When your agent uses it

  • Adding Firecrawl to an application for the first time
  • Getting a FIRECRAWL_API_KEY into a project's .env
  • Choosing the first Firecrawl SDK for a stack

Example prompts

  • “Set up Firecrawl in this project and add the key to .env.”
  • “We already use Stripe Projects. Pull the Firecrawl key from there.”
  • “Which Firecrawl SDK should our Python backend start with?”

Requirements

  • A Firecrawl account or API key
  • Node.js to run npx firecrawl-cli

Workflow steps

8 steps, taken from the first numbered list in SKILL.md.

  1. decide whether this is a fresh project or an existing codebase
  2. ask what Firecrawl should do in the product
  3. pick the narrowest endpoint that matches that behavior
  4. read the source-of-truth page for the project language before writing code
  5. add the SDK or REST call in code
  6. run a smoke test that proves one real Firecrawl request succeeds
  7. use the endpoint-specific skills in this repo for implementation guidance
  8. if you also need live web tooling during the current task, the CLI skills are already installed — use firecrawl/cli

What it can do on your machine

Read from SKILL.md and the folder at commit e5df790. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • stripe
    • npx

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Links to these hosts (documentation or services it may open):

    • docs.firecrawl.dev

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names these keys or tokens, usually read from environment variables:

    • FIRECRAWL_API_KEY
    • FIRECRAWL_API_API_KEY

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Firecrawl Build Onboarding loads about 1.4k tokens when it runs, and up to ~1.9k if it reads all its reference files. Until then it costs about 104 tokens; SKILL.md has 497 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~104
When it runs · the whole SKILL.md, loaded when a task matches
~1.4k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~1.9k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check: notes

The automated check noted patterns worth knowing about, such as sudo or a known installer.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

description
Get Firecrawl credentials and SDK setup into a project. Use when an application needs `FIRECRAWL_API_KEY`, when an agent should add Firecrawl to `.env`, when the user wants to authenticate Firecrawl for app code, or when choosing the first SDK and docs for a new Firecrawl integration. This skill includes its own browser auth flow, so it does not depend on the website onboarding skill.

Firecrawl Build Onboarding

Use this skill for the application-integration path from Firecrawl's onboarding flow.

Install

If you haven't installed yet, one command sets up both the CLI tools (for live web work) and the build skills (for app integration):

bash
npx -y firecrawl-cli@latest init --all --browser

This installs the Firecrawl CLI, the CLI skills, and these build skills together. It also opens browser auth so the human can sign in or create an account. No separate npx skills add step is needed.

Use This When

  • a project needs FIRECRAWL_API_KEY
  • the user wants Firecrawl wired into .env
  • you are adding Firecrawl to an app for the first time
  • you need to choose the first SDK or REST path

If the human still needs to sign up, sign in, or authorize access in the browser, use the auth flow reference in this skill.

If the project already uses Stripe Projects (a .projects/ directory, or stripe projects status succeeds), the key can come from there instead of the browser flow:

bash
stripe projects add firecrawl/api --name firecrawl
stripe projects env --pull

--name firecrawl is what puts the key in FIRECRAWL_API_KEY; without it the CLI writes FIRECRAWL_API_API_KEY, which the SDKs do not read. Ignore the FIRECRAWL_API_BASE_URL the CLI also writes: the SDKs read FIRECRAWL_API_URL, and only for self-hosted deployments, so leave it unset for a hosted account. Paid plans are the human's call, since stripe projects upgrade firecrawl charges their card. The docs page carries the catalog and troubleshooting.

Quick Start

If the user already has an API key, place it in .env:

dotenv
FIRECRAWL_API_KEY=fc-...

If the project is self-hosted, also set:

dotenv
FIRECRAWL_API_URL=https://your-firecrawl-instance.example.com

Then decide which integration path applies:

  • Fresh project -> choose the target stack, install the SDK, add the first Firecrawl call, and run a smoke test
  • Existing project -> inspect the repo first, then integrate Firecrawl where the project already handles third-party APIs and env vars

Docs (Source of Truth)

Read the source-of-truth page for your project language for SDK usage, schemas, and examples:

After Setup

Once the key is present:

  1. decide whether this is a fresh project or an existing codebase
  2. ask what Firecrawl should do in the product
  3. pick the narrowest endpoint that matches that behavior
  4. read the source-of-truth page for the project language before writing code
