get_hotspot_score

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are provided, so the description carries full responsibility for behavioral disclosure. It explains the formula and score interpretation, but does not state whether the operation is read-only, requires permissions, or produces side effects. For a getter it is likely safe, but that is not explicitly communicated.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is two sentences, front-loaded with the core purpose, then explains the metric and interpretation. Every sentence adds value; no redundancy or fluff. This is an exemplary concise structure.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a single-parameter tool with no annotations and no output schema, the description provides enough context: score range, metric definition, and interpretation. It could specify the return object structure (e.g., whether grade is a letter), but given the simplicity, it is sufficiently complete.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100% (the only parameter 'path' is described as 'Git repository root path.'). The description adds no additional detail about the parameter, which aligns with the baseline of 3 for high coverage. No extra semantics are provided beyond the schema.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool retrieves an overall hotspot health score (0-100) with a grade, and explains the underlying metric (churn × complexity). This distinguishes it from siblings like find_hotspots (which likely lists hotspots) and get_complexity_score (which focuses on complexity alone).

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description implies usage: when you need a high-level hotspot health score, use this tool. However, it does not explicitly specify when to prefer this over similar tools (e.g., find_hotspots or get_complexity_score) or when not to use it. No alternatives or exclusions are mentioned.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
