Agent Personas

NeuBird includes three built-in agent personas, each powered by a different Claude model optimized for a specific trade-off between speed and reasoning depth.

Personas

Persona	Model	Speed	Depth	Best for
Responder	Claude Haiku	Fast	Light	Quick triage, confirming whether an issue is active, getting immediate next actions
Analyst	Claude Sonnet	Balanced	Deep	Root cause analysis, multi-service investigations, detailed evidence gathering
Architect	Claude Opus	Thorough	Maximum	Writing runbooks, design reviews, systemic fix proposals, complex cross-service analysis

Switching personas

Type /agent to open the persona picker. Use ↑ ↓ to select and Enter to confirm. The switch takes effect immediately — your next question uses the new persona.

You can also switch mid-investigation. If a Responder triage reveals a deeper issue, switch to Analyst for the full RCA.

When to use each

Start with Responder when you need speed:

• "Is the checkout service down right now?"
• "What's the current error rate on api-gateway?"

Switch to Analyst for investigation:

• "Why did latency spike at 2am?"
• "What's causing the increase in 503 errors?"

Escalate to Architect for systemic work:

• "Write a runbook for handling RDS ACU saturation"
• "What architectural changes would prevent this class of incident?"

Custom personas

Create your own personas by adding .md files to skills/agents/:

---
model: claude-sonnet-4-6
speed: 2
quality: 2

You are a cloud cost specialist. When investigating costs, always break down by service, team, and resource type. Always include a projected monthly cost at the end of your analysis.

The frontmatter sets the model and the speed/quality ratings shown in the picker. The body is appended to the system prompt.
