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

With no annotations, the description carries the full burden. It does disclose a genuine behavioral fact beyond the schema: 3 reports from different accounts auto-pause the entry. However, it omits auth requirements, what a successful submission returns, and whether reports are reversible, so the disclosure is partial.

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?

Three short sentences, front-loaded with the action, then the consequence, then the args. Minimal waste, though the terse args list could carry a little more substance.

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 two-parameter mutation with no annotations and no output schema, the mention of auto-pause is valuable, but the definition is silent on the return value, the optionality/format of reason, and any per-account rate limits.

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 compensate, yet it only lists 'Args: slug, reason' with no added meaning. It does not say that slug identifies the target entry or what the optional reason should contain, adding essentially nothing over the property names.

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 (Report) and resource (a library entry), and enumerates the qualifying conditions (broken, unsafe, spammy). It is distinguishable from siblings like library_rate or library_install, though it never explicitly names an alternative.

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 enumerated report conditions imply when to use it (on broken/unsafe/spammy entries) but there is no explicit when-not guidance, no prerequisites, and no named alternative such as library_rate for other feedback.

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