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.

Example: skills/agents/cost-specialist.md
