Agent Personas
NeuBird includes three built-in agent personas, each using a different Claude model tuned for a different trade-off between speed and depth.
Personas
| Persona | Model | Speed | Quality | Best for |
|---|---|---|---|---|
| Responder | claude-haiku-4-5 | ⚡⚡⚡ | ★☆☆ | Fast triage, immediate next actions |
| Analyst | claude-sonnet-4-6 | ⚡⚡○ | ★★☆ | Root cause analysis, deep investigation |
| Architect | claude-opus-4-6 | ⚡○○ | ★★★ | Runbooks, design reviews, systemic fixes |
Switch persona at any time with /agent.
Responder
The Responder uses Claude Haiku for maximum speed. It is best for:
- Confirming whether an incident is ongoing
- Getting an immediate triage summary
- Identifying the next action to take
Analyst
The Analyst uses Claude Sonnet for balanced speed and depth. It is the default persona and best for:
- Full root cause analysis (RCA)
- Multi-service investigations
- Latency, error rate, and cost investigations
Architect
The Architect uses Claude Opus for maximum reasoning depth. It is best for:
- Writing runbooks from investigation results
- Designing systemic fixes
- Design review questions that require reasoning over multiple investigations
Custom personas
You can add your own agent personas as .md files in skills/agents/. The frontmatter sets the model, speed, and quality rating; the body is appended to the system prompt.
