get_dependency_changes

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

Annotations already declare readOnlyHint and openWorldHint, so safety and reach are covered. The description adds the source-resolution fallback order (AndroidX/AGP docs first, else GitHub releases), which is genuine behavioral context, but omits auth needs, rate limits, or failure behavior when neither source applies.

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?

A single, front-loaded sentence that states purpose first and qualifiers second. The parenthetical source clause is slightly dense but earns its place by explaining where the changelog comes from.

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?

An output schema exists, so return-value documentation is unnecessary, and the read-only/open-world annotations cover the safety profile. The description adequately covers the operation and its source resolution; only explicit usage guidance is absent.

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 all five parameters (including the exclusive fromVersion and inclusive toVersion semantics) are already documented in the schema. The description adds only the phrase 'between two versions,' which does not extend meaning beyond the schema. Baseline 3 applies.

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?

States a specific verb and resource: retrieving changelog/release notes between two versions, with source detail (AndroidX/AGP docs vs GitHub releases). It is clear what the tool returns, though it does not explicitly contrast itself against siblings like get_latest_version or compare_dependency_versions.

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?

No when-to-use, when-not-to-use, or alternative-tool guidance is provided. The description merely describes output content and source resolution, leaving the agent to infer when this tool is preferable to its many siblings.

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