## What it does

AutoBrowse builds a browser automation skill by repetition. An inner agent browses the site through `evaluate.ts`; you, the outer agent, read what happened and improve `strategy.md`. Repeat until it passes consistently.

Invocation is loose. `/autobrowse --task google-flights` runs one task, `/autobrowse --tasks a,b` or `/autobrowse --all` runs several, spawning one sub-agent per task in parallel. Drop a URL or a plain sentence instead and the skill picks a kebab-case name, scaffolds `task.md` from the template and carries on.

You need Node.js 18+, the `browse` CLI and `ANTHROPIC_API_KEY` in the environment or in a `.env` file in the working directory. Run it from the autobrowse app directory. `--browser-trace` is off by default, works only with `--env remote`, needs the sibling `browser-trace` skill and `BROWSERBASE_API_KEY`, and errors out if you pair it with `--env local`. Training artifacts land in `./autobrowse/` in the current directory rather than `~/.claude/skills/`, so keep the working folder separate from your Claude home directory.

## Requirements
- Works with: Playwright

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add browserbase/skills --skill autobrowse -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/autobrowse/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/autobrowse/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add browserbase/skills --skill autobrowse -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/autobrowse/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add browserbase/skills --skill autobrowse -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/autobrowse/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install browserbase/skills autobrowse
```

2. **Manually: put the files in place**
- File: `.github/skills/autobrowse/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add browserbase/skills --skill autobrowse -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/browserbase/skills --path skills/autobrowse
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/autobrowse/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add browserbase/skills --skill autobrowse -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/browserbase/skills/tree/HEAD/skills/autobrowse/SKILL.md

## When to use it
- get a browsing task to pass consistently
- read a trace and find where navigation breaks
- rewrite `strategy.md` from run results
- run several site tasks in parallel with sub-agents
- collect a per-iteration report with cost and status

## Example prompts
- /autobrowse --task google-flights
- /autobrowse --tasks google-flights,amazon-add-to-cart
- /autobrowse fix the existing google-flights skill

# AutoBrowse — Self-Improving Browser Skill

Build reliable browser automation skills through iterative experimentation. An inner agent browses the site (`evaluate.ts`). You — the outer agent — read what happened and improve the instructions (`strategy.md`). Repeat until it passes consistently.

## Entry Points

Invocation is flexible — both explicit flags and free-form natural language work:

```
/autobrowse --task google-flights
/autobrowse --task google-flights --iterations 10 --env remote
/autobrowse --task google-flights --browser-trace
/autobrowse --tasks google-flights,amazon-add-to-cart
/autobrowse --all

# Also fine — parse freely:
/autobrowse https://flights.google.com/
/autobrowse book a flight on delta.com
/autobrowse fix the existing google-flights skill
```

`--browser-trace` (default off, remote-only): pairs each iteration with the sibling `browser-trace` skill — wraps the inner agent in a CDP capture for per-page network/console/page-lifecycle evidence. Implies `--env remote`; errors if combined with `--env local`. Requires the sibling `browser-trace` skill present at `${CLAUDE_SKILL_DIR}/../browser-trace/`, and the `BROWSERBASE_API_KEY` env var.

When the user drops a URL or free-form instruction instead of `--task <name>`:
- If an existing task in `${WORKSPACE}/tasks/` clearly matches the site/intent, use it.
- Otherwise, pick a short kebab-case name, create `${WORKSPACE}/tasks/<name>/task.md` from `${CLAUDE_SKILL_DIR}/references/example-task.md`, fill in the URL/goal based on what the user said, and proceed. Tell the user the chosen name in one line.

---

## How to run

### Step 1 — Parse arguments and orient

Check what was passed:
- `--task <name>` → single task mode
- `--tasks a,b,c` or `--all` → multi-task mode (spawn sub-agents)
- `--iterations N` → how many evaluate → improve cycles (default: 5)
- `--env local|remote` → browser environment (default: local; use remote for bot-protected sites)
