## Common Workflows

### Web Research Workflow

1. Use `run_deep_research` with your research question
2. Review the synthesized markdown report
3. Use `run_browser_agent` for follow-up exploration of specific sources
4. Check `task_list` to monitor progress

```
# Step 1: Deep research
run_deep_research
topic: What are the best practices for MCP server development in 2025?
max_searches: 8

# Step 2: Follow-up investigation
run_browser_agent
task: Go to the top-ranked article and extract code examples
```

### Form Automation Workflow

1. Use `run_browser_agent` with task describing the form
2. Include URL if known, or let agent search for it
3. Agent navigates, fills fields, and submits
4. Use `task_get` to verify completion

```
run_browser_agent
task: Fill out the contact form at https://example.com/contact with name "John Doe", email "[email protected]", and message "Request for demo"
max_steps: 30
```

### Learning and Reusing Skills

1. Run `run_browser_agent` with `learn: true` to discover APIs
2. Agent records network calls and extracts patterns
3. Save skill with `save_skill_as`
4. Use `skill_list` to see learned skills
5. Reuse with `skill_name` parameter for faster execution

```
# Step 1: Learn a skill
run_browser_agent
task: Go to Hacker News and extract the top 10 stories with titles, URLs, and scores
learn: true
save_skill_as: hackernews_top_stories

# Step 2: List learned skills
skill_list

# Step 3: Reuse the skill (faster direct execution)
run_browser_agent
task: Get current top stories from Hacker News
skill_name: hackernews_top_stories
skill_params: {"limit": 5}
```

### Long-Running Task Management

1. Start a browser automation task (runs in background)
2. Use `task_list` to check status
3. Use `task_get` for detailed progress
4. Use `task_cancel` if needed

```
# Step 1: Start task
run_browser_agent
task: Research all articles on example.com blog and create a summary
max_steps: 200

# Step 2: Check progress
task_list
status_filter: running

# Step 3: Get details
task_get
task_id: a1b2c3d4

# Step 4: Cancel if needed
task_cancel
task_id: a1b2c3d4
```

## Advanced Features

### Skill-Based Execution

When a skill is learned with API endpoints, it supports **direct execution** which bypasses the AI agent for much faster performance:

- First run: Agent explores the website (60-120 seconds)
- Skill learned: API patterns extracted and saved
- Subsequent runs: Direct API calls (2-5 seconds)

**Fallback behavior:** If direct execution fails (auth required, API changed), automatically falls back to agent-based execution.

### Progress Tracking

Both `run_browser_agent` and `run_deep_research` support real-time progress tracking:

- Step-by-step nav
