engineering_compare_model_versions

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

The description adds only generic dispatcher/auth context and says nothing about side effects, state changes, or why the annotation marks this as destructiveHint=true. For a tool flagged destructive with no idempotency, the description should disclose what the operation changes or risks.

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 compact and front-loaded, with the action and domain stated first and no filler. The routing sentence and Args list are minimal. The brevity is good, but it comes partly at the expense of substantive detail.

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 tool with no schema-level parameter descriptions, no required parameters, and a destructive annotation, the description leaves out essential details: expected inputs, output behavior, and side effects. The presence of an output schema helps with return values, but an agent still cannot confidently construct a valid invocation or decide when this tool is appropriate.

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?

The Args section clarifies that 'message' is a free-text objective and 'inputs' is an optional JSON string, which adds a little beyond the bare schema. But it does not specify what the JSON should contain, what a valid objective looks like, or how the two parameters interact; with 0% schema description coverage, 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 names the exact action being run ('compare_model_versions') and places it in the 'engineering domain agent' context, which distinguishes it from the many unrelated siblings. However, it never explains what comparing model versions actually does, relying on the action name for meaning. This is specific but shallow.

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?

There is no guidance on when to use this tool versus the many other engineering_* or domain-agent tools. The routing sentence describes mechanics ('dispatcher under your JWT, tenant, and company scope') rather than selection criteria or exclusions.

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