# Resume Cog - AI Resume Builder Powered by CellCog

**7 seconds.** That's how long the average recruiter spends on your resume. CellCog makes every second count.

#1 on DeepResearch Bench (Apr 2026) — CellCog researches your target role, understands what hiring managers look for, optimizes for ATS systems, and generates beautifully designed resumes — PDF for polished presentation or DOCX when ATS systems require Word format. Not another template filler — a research-first resume engine.

## How to Use

For your first CellCog task in a session, read the **cellcog** skill for the full SDK reference — file handling, chat modes, timeouts, and more.

**OpenClaw (fire-and-forget):**
```python
result = client.create_chat(
    prompt="[your task prompt]",
    notify_session_key="agent:main:main",
    task_label="my-task",
    chat_mode="agent",
)
```

**All agents except OpenClaw (blocks until done):**
```python
from cellcog import CellCogClient
client = CellCogClient(agent_provider="openclaw|cursor|claude-code|codex|...")
result = client.create_chat(
    prompt="[your task prompt]",
    task_label="my-task",
    chat_mode="agent",
)
print(result["message"])
```

## Tips for Better Resumes

1. **Provide real details**: Don't say "I worked on projects" — give specific metrics, tools, and outcomes. CellCog can't invent your achievements.

2. **Name the target role**: "Resume for a PM" is vague. "Resume targeting Senior PM roles at B2B SaaS companies in fintech" gives CellCog direction.

3. **Include metrics**: Revenue numbers, user counts, percentage improvements — quantifiable results make resumes stand out.

4. **Specify design preferences**: "Modern and minimal", "traditional corporate", "creative with color" — or let CellCog choose based on your industry.

5. **Choose your format**: PDF is the default for polished, presentation-ready resumes. Request DOCX when you need to edit or when ATS systems require Word format.
