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

Annotations already declare readOnlyHint=true, destructiveHint=false and openWorldHint=false, so the safety profile is covered. The description adds only the word 'recent', without disclosing ordering, truncation, or whether logs are streamed or historical — modest added value against a low bar.

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 with zero filler, which is appropriate for a simple read tool. It is arguably under-specified rather than over-long, so it sits just below the top of the range.

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 low-complexity read tool with full schema coverage, complete annotations, and no output schema (so return-format explanation is unnecessary), the description covers the essentials. The only real gap is the absence of guidance on when logs are the right signal versus status or health.

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 three parameters (deploymentId, type with build/runtime, limit with max 1000) are fully documented in the schema. The description adds no syntax, default, or format detail beyond it, so the 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 (returns) and resource (log lines) scoped to a deployment, which clearly separates it from siblings like nexusai_deploy_status and nexusai_deploy_health that report state rather than output. It does not, however, name any sibling explicitly, so the differentiation is inferable rather than stated.

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 offers no when-to-use guidance and no exclusions; it never tells the agent to prefer this over nexusai_deploy_status or nexusai_deploy_health when diagnosing a deployment. Usage is only weakly implied by the word 'logs'.

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