Before reviewing the issues, create an internal map of the semantic purpose of each available label based on its name. For each label, define both its positive meaning and, if applicable, its exclusionary criteria.

-`kind/bug`: An error, flaw, or unexpected behavior in existing code.

**Example Semantic Map:**
60+
* `kind/bug`: An error, flaw, or unexpected behavior in existing code. *Excludes feature requests.*
61+
* `kind/enhancement`: A request for a new feature or improvement to existing functionality. *Excludes bug reports.*
62+
* `priority/p1`: A critical issue requiring immediate attention, such as a security vulnerability, data loss, or a production outage.
63+
* `good first issue`: A task suitable for a newcomer, with a clear and limited scope.

Based on your semantic map, establish a set of general principles to guide your decisions in ambiguous cases. These principles should include:

This semantic map will serve as your classification criteria.
71+
* **Precision over Coverage:** It is better to apply no label than an incorrect one. When in doubt, leave it out.
72+
* **Focus on Relevance:** Aim for high signal-to-noise. In most cases, 1-3 labels are sufficient to accurately categorize an issue. This reinforces the principle of precision over coverage.
73+
* **Heuristics for Priority:** If priority labels (e.g., `priority/p0`, `priority/p1`) exist, map them to specific keywords. For example, terms like "security," "vulnerability," "data loss," "crash," or "outage" suggest a high priority. A lack of such terms suggests a lower priority.
74+
* **Distinguishing `bug` vs. `enhancement`:** If an issue describes behavior that contradicts current documentation, it is likely a `bug`. If it proposes new functionality or a change to existing, working-as-intended behavior, it is an `enhancement`.
75+
* **Assessing Issue Quality:** If an issue's title and body are extremely sparse or unclear, making a confident classification impossible, it should be excluded from the output.
