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

Annotations already declare readOnlyHint=true and openWorldHint=false, so safety is covered. The description adds only the alert taxonomy; it says nothing about freshness window, ordering, whether alerts are deduplicated or acknowledged, or how severity thresholds are applied.

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?

It is a single tight fragment with no filler, and the category list is front-loaded. However, the terseness stems from under-specification rather than disciplined editing — a fragment without a verb leaves the operation implicit.

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 three undocumented parameters, no output schema, and no explanation of what an alert record contains, the definition leaves an agent unable to invoke the tool correctly beyond calling it with no arguments. More detail on filters and the recency window is needed.

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?

All three parameters (limit, token, severity) have 0% schema description coverage and the description explains none of them. There is no hint that severity filters alert types, that token scopes alerts to one asset, or what limit defaults to.

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 names the resource (threshold alerts) and enumerates the four alert categories, which lets an agent distinguish it from siblings like tc_brief, tc_calendar, and tc_status. It omits an explicit verb, but the noun phrase clearly implies retrieval of recent alerts.

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 when-to-use guidance, no statement of what 'recent' means, and no mention of alternatives. An agent cannot tell whether tc_alerts or tc_brief/tc_status should be consulted for a given monitoring question.

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