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

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, so safety and repeatability are covered. The description adds the propagation nuance (commit appearing here), which is useful behavioral context, but it does not describe the response contents or any latency characteristics beyond the vague propagation note.

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 short sentences with the core purpose front-loaded. The second sentence is somewhat jargon-heavy ('racing edge propagation') but is compact and adds intent rather than padding.

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?

With no output schema, the description carries the burden of explaining the return value, and 'deployment health and build' is not concrete about what fields or statuses come back. For a health-check tool whose whole value is interpreting the response, this is a meaningful but not fatal gap.

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 tool takes zero parameters and the schema is empty, so there is nothing for the description to disambiguate. Baseline of 4 applies since parameter semantics are trivially complete.

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 a specific verb and resource: 'Read deployment health and build.' This is distinguishable from the many sibling management tools, though it does not explicitly differentiate itself from adjacent smoke/operations tools like commsharbor_domain_smoke or commsharbor_operations. Clear but not sibling-routing.

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 second sentence implies usage context ('Smoke tests wait for their own commit to appear here instead of racing edge propagation'), which tells the agent this is a polling/target for verification flows. However, there is no explicit when-to-use versus when-not guidance or named alternative tool, so usage is implied rather than stated.

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