github_dependency_graph_diff_range

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

No annotations are provided, so the description carries the full burden. It only states the basic purpose, with no disclosure of side effects, output format, authentication requirements, or rate limits. For a potentially expensive or state‐reading operation, this lack of transparency is a gap.

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 extremely concise at one sentence. It is front‐loaded with the key action. However, it could include additional structured details (e.g., about the output) without harming conciseness. For its minimal length, it is appropriate.

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?

Given the tool has 4 parameters, no output schema, and no annotations, the description is insufficient. It does not explain what 'diff of dependencies' entails, what the output format is, or how to correctly specify the commit range via 'basehead'. The context for an agent to use this tool effectively is lacking.

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%, so baseline is 3. However, the descriptions are minimal (e.g., 'owner', 'repo', 'basehead') and add little beyond the parameter names. Only 'name' has a meaningful description. The tool description does not further clarify parameter semantics, such as the expected format of 'basehead' (e.g., commit range 'base...head'). Thus, just meets baseline but does not exceed.

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 states 'Get a diff of the dependencies between commits', clearly indicating the tool's purpose. The verb 'Get' and resource 'diff of dependencies' are specific. The tool name includes 'diff_range', reinforcing the concept. However, it does not elaborate on what 'between commits' means (e.g., comparing two specific commits or a range). Still, it is distinct from sibling tools like 'github_dependency_graph_create_repository_snapshot' and 'github_dependency_graph_export_sbom'.

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 provides no guidance on when to use this tool versus alternatives, nor any exclusions or prerequisites. Sibling tools include many other GitHub API operations, but no differentiation is offered. An agent would have no help deciding between this and other dependency-related tools.

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