Browserbase CLI Skill | Agent Skills

Browserbase CLI

Use the official bb CLI for Browserbase platform operations, Functions workflows, and Fetch API calls.

Setup check

Before using the CLI, verify it is installed:

which bb || npm install -g @browserbasehq/cli
bb --help

For authenticated commands, set the API key:

export BROWSERBASE_API_KEY="your_api_key"

If using bb functions dev or bb functions publish, also set:

export BROWSERBASE_PROJECT_ID="your_project_id"

When to use this skill

Use this skill when the user wants to:

run Browserbase commands through bb
scaffold, develop, publish, or invoke Browserbase Functions
inspect or manage Browserbase sessions, projects, contexts, or extensions
fetch a page through Browserbase without opening a browser session
search the web through Browserbase without opening a browser session

When not to use this skill

For interactive browsing, page inspection, screenshots, clicking, typing, or login flows, prefer the browser skill.
For simple HTTP content retrieval where the user does not care about using the CLI specifically, the dedicated fetch skill is often a better fit.
Use bb browse ... only when the user explicitly wants the CLI wrapper or is already working in a bb-centric workflow.

Command selection

bb functions for local dev, packaging, publishing, and invocation
bb sessions, bb projects, bb contexts, bb extensions for Browserbase platform resources
bb fetch <url> for Fetch API requests
bb search "<query>" for Search API requests
bb browse ... to forward to the standalone browse binary (requires @browserbasehq/browse-cli)
bb skills install to install Browserbase agent skills for Claude Code

Common workflows

Functions

bb functions init my-function
cd my-function
bb functions dev index.ts
bb functions publish index.ts
bb functions invoke <function_id> --params '{"url":"https://example.com"}'

Use bb functions invoke --check-status <invocation_id> to poll an existing invocation instead of creating a new one.

Platform APIs

bb projects list
bb sessions get <session_id>
bb sessions downloads get <session_id> --output session-artifacts.zip
bb contexts create --body '{"region":"us-west-2"}'
bb extensions upload ./my-extension.zip

Fetch API

bb fetch https://example.com
bb fetch https://example.com --allow-redirects --output page.html

Search API

bb search "browser automation"
bb search "web scraping" --num-results 5
bb search "AI agents" --output results.json

Best practices

Prefer bb --help and subgroup --help before guessing flags.
Use dash-case flags exactly as shown in CLI help.
Use --output <file> on bb fetch and bb search to save results to a file.
Use environment variables for auth unless the user explicitly wants one-off overrides.
Pass structured request bodies with JSON strings in --body or --params.
Remember that bb functions ... uses --api-url, while platform API commands use --base-url.
If bb browse fails because browse is missing, either install @browserbasehq/browse-cli or switch to the browser skill.

Troubleshooting

Missing API key: set BROWSERBASE_API_KEY or pass --api-key
Missing project ID on bb functions dev or bb functions publish: set BROWSERBASE_PROJECT_ID or pass --project-id
Unknown flag: rerun the relevant command with --help and use the exact dash-case form
bb browse install error: run npm install -g @browserbasehq/browse-cli
