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

No annotations are provided, so the description carries the full disclosure burden. It does not state that this is a read-only query, whether it makes network calls, whether hit rate limits apply, or what a 'comprehensive' check includes — only the read-only nature is weakly implied by 'health check'.

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. Nothing is wasted and the core action appears immediately.

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 annotations and no output schema, the description should say what the health check reports and roughly what it returns. 'Comprehensive' is the only hint, leaving scope and return content undefined for a tool whose value depends on what it surfaces.

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 coverage is 100% and the single parameter is fully described ('Package name on hex.pm'), so the description need not carry parameter burden. It adds nothing beyond the schema, which is acceptable at this coverage level — baseline 3.

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 verb and resource (run a package health check), so the general action is clear. However, 'health' is left undefined — nothing says whether it covers dependencies, versions, security, or documentation — so the agent cannot tell how it differs from siblings like audit, upgrade_check, or info.

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 guidance and no mention of alternatives. With close siblings such as audit and audit_mix_deps in the list, the agent gets no signal for choosing this tool over those; usage must be inferred from the name alone.

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