analyze_repository_ownership

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

Annotations already declare readOnlyHint=true, which is consistent with 'Analyze' and 'Provides recommendations'. The description adds valuable context about the types of analysis performed (bus factor, knowledge concentration, etc.) and the fact that it outputs recommendations, which goes beyond the annotation's safety info. It does not mention data limitations or rate limits, but within the read-only scope it is sufficiently transparent.

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?

Two sentences, front-loaded with the main action, and every word contributes. It is concise without sacrificing key output details.

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?

There is no output schema, so the description carries the duty of conveying return values. It lists all key analysis outputs and mentions recommendations, giving a complete picture for a 2-parameter tool with read-only annotations. No gaps in understanding of what to expect.

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% (both owner and repo have clear descriptions). The description does not add parameter-specific details, but the schema already provides full meaning. Baseline 3 is appropriate because the schema carries the heavy lifting.

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 uses a specific verb ('Analyze') and resource ('a GitHub repository's contributor data') and enumerates concrete outputs (bus factor, knowledge concentration, contribution percentages, ownership risk). It is clear and detailed, but does not explicitly distinguish itself from sibling tools like calculate_bus_factor or analyze_knowledge_risk, which is the only difference from a perfect score.

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 for analyzing repository ownership risk and providing recommendations, but gives no explicit guidance on when to choose this tool over alternatives. Sibling tools such as calculate_bus_factor and analyze_knowledge_risk suggest overlapping functionality, and the description does not address trade-offs or scenarios where this tool is preferable.

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