verify_button_render_change

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

With no annotations, the description must disclose behavioral traits like read-only nature or auth requirements. It only states 'compare', implying no side effects, but does not confirm safety (e.g., no destruction or modification). The output schema exists but is not described, leaving agents unaware of response format. Minimal behavioral transparency.

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 a single, front-loaded sentence with no wasted words. However, it is under-specified, trading conciseness for completeness. It earns its place but leaves significant gaps.

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 required parameters and an output schema, the description fails to explain the return value or how the result relates to other sibling tools like 'get_button_runtime_summary'. It lacks context for integration into workflows like preview-then-verify sequences.

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 0%, so the description must explain parameters. It only mentions 'previous preview hash' which mirrors the parameter name 'previous_sha256'. No explanation of 'page', 'row', or 'column' is provided, meaning agents must infer their meaning from context. This is insufficient.

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 compares a current button preview fingerprint to a previous hash, indicating its purpose for verifying render changes. This distinguishes it from sibling tools like 'preview_button_template' or 'set_button_style_verified' which involve previewing or setting styles, not verification. However, it could be more explicit about the output (e.g., returns true/false).

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 guidance is provided on when to use this tool versus alternatives like 'press_button_verified' or when not to use it. The description implies it follows a preview step, but this is not explicitly stated. Lacks context on prerequisites or exclusions.

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