Persona Anchors for Agent Styling
Pattern: Direct agents to emulate specific engineering styles and values by anchoring to recognized names in the field.
The Core Insight
LLMs have absorbed the public writing, talks, and code of well-known engineers. This knowledge can be probed and leveraged—without web access—to shape agent behavior toward specific styles and quality standards.
How It Works
- Name a practitioner whose style matches the desired output
- Tell the agent to emulate their values and craft
- The agent draws on training data to approximate that style
This works because LLMs encode patterns from public artifacts—blog posts, conference talks, open-source contributions—associated with named individuals.
Pattern: Domain-Specific Anchors
React Native Projects
Emulate the craft and values of React Native product engineers like
Evan Bacon and Fernando Rojo. Prioritize developer experience,
practical abstractions, and polished user interactions.Generic React Native (No Specific Product)
Emulate the taste and architectural decisions of the Callstack crew.
Focus on maintainability, clear module boundaries, and patterns that
scale across teams.Backend Systems
Emulate the operational discipline of engineers like Kelsey Hightower.
Infrastructure as code, explicit configuration, no snowflakes.Distributed Systems
Emulate the rigor of the FoundationDB or CockroachDB teams. Correctness
first, performance second, explicit handling of edge cases.Probing for Recognition
To discover which names an agent recognizes without web access:
Without using web search, describe the engineering values and style
associated with [Name]. What patterns would you expect in their work?If the agent produces a coherent description, that name is usable as an anchor. If the response is vague or generic, choose a different anchor.
When to Use Persona Anchors
| Situation | Effectiveness |
|---|---|
| Greenfield project, no established patterns | High - provides default direction |
| Codebase with strong existing conventions | Low - existing patterns dominate |
| Team with shared style idols | High - aligns agent with team taste |
| Generic/scaffold code | Medium - adds polish without over-engineering |
Anti-Patterns
- Over-specifying - Listing too many names creates confusion
- Contradictory anchors - "Like [minimalist] and [enterprise architect]" fights itself
- Unknown names - If the model doesn't know them, the anchor is noise
- Using for factual questions - Anchors shape style, not correctness
The "Lie" Is the Feature
Persona anchors are a controlled hallucination. The model isn't actually those engineers—but it produces better output when directed toward a coherent style.
This is the same principle as "act as a senior engineer"—except specific names carry more signal because they encode real patterns from training data.
Practical Template
## Style Anchor
For this project, emulate the values and craft of [Domain] practitioners
like [Name 1] and [Name 2].
Key characteristics:
- [Value 1]
- [Value 2]
- [Value 3]
When in doubt, ask: "Would [Name] approach it this way?"
