What it does

Bb Browser is an agent skill from Peiiii/nextclaw. Use when the user wants browser-backed web data access, authenticated fetches, website adapters, or safe browser automation through a local bb-browser installation.

Its SKILL.md is about 1.8k tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files (for example `marketplace.json`).

It sits in Productivity & Automation, covering Browser automation. The repository describes itself as: A human-centered long-term AI partner—not a task-centered assistant. The licence is MIT.

When your agent uses it

  • The user wants browser-backed web data access
  • Authenticated fetches
  • Website adapters
  • Safe browser automation through a local bb-browser installation

Example prompts

  • “/bb-browser”

Requirements

  • Node.js

Workflow steps

6 steps, taken from the step headings in SKILL.md.

  1. Classify the task
  2. Verify the CLI exists
  3. Choose the execution path
  4. Run a readiness check
  5. Run one read-only smoke before risky work
  6. Execute the smallest matching command

What it can do on your machine

Read from SKILL.md and the folder at commit 973722e. 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:

    • npm

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

  • Network

    No URLs in SKILL.md. Its commands use npm, which can reach the network depending on how they are called.

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

  • Credentials

    Names no API keys, tokens, secrets or passwords.

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

Context cost

Bb Browser loads about 1.8k tokens when it runs. Until then it costs about 44 tokens; SKILL.md has 849 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~44
When it runs · the whole SKILL.md, loaded when a task matches
~1.8k

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 passed

The automated check found no risky patterns in SKILL.md.

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.

bb-browser

Overview

Use this skill when the user wants to use the web through their real browser session inside NextClaw.

This marketplace skill wraps the upstream epiral/bb-browser project for NextClaw users.

Be explicit about the boundary:

  • This skill owns explanation, installation guidance, readiness checks, workflow selection, and risk disclosure.
  • The local bb-browser CLI owns actual browser execution.
  • The user's browser login state owns access to private pages and authenticated requests.

Do not pretend the environment is ready when it is not.

What This Skill Covers

  • site adapters such as twitter/search, reddit/thread, github/repo, zhihu/hot, youtube/transcript,
  • authenticated browser-backed fetch,
  • browser automation flows such as open, snapshot, click, fill, eval, network requests, and screenshot,
  • local daemon mode with the user's real Chrome state,
  • optional --openclaw path when the user already wants to run through OpenClaw's browser,
  • first-use setup and bounded troubleshooting.

What This Skill Does Not Cover

  • inventing site adapters or flags that bb-browser does not expose,
  • pretending a site command is safe when it can write, post, delete, purchase, or change account state,
  • hiding missing prerequisites such as the local CLI, running browser, daemon connectivity, or login state,
  • presenting third-party browser execution as native built-in NextClaw capability,
  • silently creating or publishing new adapters to the upstream ecosystem.

Install Boundary

Always distinguish these paths:

  • NextClaw marketplace skill install: nextclaw skills install bb-browser
  • Upstream runtime install: npm install -g bb-browser
  • Optional MCP wiring outside NextClaw: configure bb-browser --mcp in the target MCP client

Installing the marketplace skill does not install the upstream runtime automatically.

Deterministic First-Use Workflow

When the user asks for a bb-browser task, follow this order.

1. Classify the task

Choose exactly one:

  • site read,
  • browser read,
  • browser write or account-affecting action,
  • adapter authoring or reverse-engineering help.

Prefer the smallest workflow that fits the request.

2. Verify the CLI exists

Run:

bash
command -v bb-browser
bb-browser --version

If missing, explain that the local runtime is not installed yet.

Recommended install:

bash
npm install -g bb-browser

Do not continue to the real task until bb-browser exists.

3. Choose the execution path

Use exactly one of these:

  • Default daemon path Use the user's local Chrome session.
  • OpenClaw path Only when the user explicitly wants OpenClaw or already has that browser path ready. Every site command must include --openclaw.

Do not mix the two paths in one command.

4. Run a readiness check

For the default daemon path, ask the user to keep Chrome running, then run:

bash
bb-browser status --json

If it reports running: false or no daemon state, try:

bash
bb-browser daemon

Then re-run:

bash
bb-browser status --json

Success means the daemon is running and Chrome is connected.

For the OpenClaw path, first verify bb-browser exists, then use a lightweight read such as:

bash
bb-browser site list --openclaw

If that works, proceed with the real site task.

5. Run one read-only smoke before risky work

Prefer a read-only command first.

Examples:

bash
bb-browser site list
bb-browser site info reddit/thread
bb-browser site recommend
bb-browser get title
bb-browser eval "document.title"

If adapter coverage is the goal, refresh the community adapter list first:

bash
bb-browser site update

Do not jump straight into write actions if a small read can verify readiness first.

6. Execute the smallest matching command

Examples:

bash
bb-browser site reddit/hot
bb-browser site github/repo owner/repo
bb-browser site youtube/transcript VIDEO_ID
bb-browser fetch https://example.com/api/me --json
bb-browser open https://example.com
bb-browser snapshot -i
bb-browser click @3
bb-browser fill @5 "hello"
bb-browser network requests --with-body

If using OpenClaw for site commands:

bash
bb-browser site reddit/hot --openclaw
bb-browser site xueqiu/hot-stock 5 --openclaw --jq '.items[] | {name, changePercent}'

Safe Execution Rules

  • Prefer site adapters over manual browser clicking when both can solve the task clearly.
  • Prefer read-only commands before writes.
  • Treat posting, deleting, following, liking, submitting forms, changing settings, purchases, and account mutations as write actions that need explicit confirmation unless the user already gave a clear scoped instruction.
  • If the request only needs information extraction, prefer site, fetch, get, or eval before click or fill.
  • If using snapshot refs, remember that refs are temporary and must be refreshed after navigation or page changes.
  • Close tabs that you opened for the task when they are no longer needed.

Troubleshooting

bb-browser not found
  • Explain that the upstream CLI is not installed locally.
  • Guide installation with npm install -g bb-browser.
  • Re-check with command -v bb-browser.
Daemon not running or Chrome not connected
  • Ask the user to keep Chrome open.
  • Run bb-browser status --json.
  • If needed, start the daemon with bb-browser daemon and check status again.
  • If startup still fails, be explicit that the local browser bridge is not ready yet.
Site command fails or returns unauthorized data
  • Explain that the most likely cause is missing or expired login state in the browser.
  • Ask the user to log into the target site in Chrome or OpenClaw browser, then retry.
Adapter missing or outdated
  • Use:
bash
bb-browser site list
bb-browser site search <keyword>
bb-browser site info <name>
bb-browser site update
  • Do not claim support for an adapter you have not confirmed.
Ref stopped working
  • Explain that @ref values expire after navigation or DOM changes.
  • Re-run:
bash
bb-browser snapshot -i
The user wants a brand new website adapter
  • Be explicit that this is upstream adapter-authoring work, not guaranteed built-in support.
  • Use bb-browser guide to inspect the upstream guide before proposing implementation steps.
  • Do not claim the adapter already exists unless site list or site search proves it.

Success Criteria

This skill is working correctly when:

  • the user understands that execution is performed by the local bb-browser runtime,
  • missing CLI, daemon, browser, or login prerequisites are identified before task execution,
  • a read-only smoke succeeds before heavier workflows when appropriate,
  • write actions stay behind explicit confirmation when required,
  • and the final task runs only after the environment is truly ready.
