# Identity Approaches for Claude Prompts
> **Calibration:** Tier 1 (Model-compatible) - runs cleanly on the current dual-primary tier (Opus 5, Sonnet 5) as well as Haiku 4.5 with extended thinking. Structured retrieval, rule evaluation, or template lookup - output shape does not depend on model class. Correct-shape output also on Opus 4.8 (fallback-graceful) and Sonnet 4.6 (legacy-graceful). See repository README for model compatibility.
Identity is the first layer of a well-structured Claude prompt. It defines WHO Claude is for a task — shaping the depth of analysis, the vocabulary used, the reasoning style applied, and what Claude treats as obvious versus what requires explanation.
A prompt without a clear identity produces generic output. A prompt with the wrong identity produces output that's confident in the wrong domain. Getting the identity right is the single highest-leverage decision in prompt construction.
## When to Use This Skill
- You are building a Claude prompt and need to choose or define a role/persona
- You have a prompt whose output lacks domain-appropriate depth or vocabulary
- You need to decide which expert perspective fits a task
- You want to build a custom identity for a specialized domain
