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

Annotations already declare readOnly, idempotent, non-destructive, so the safety profile is covered. The description adds genuinely new behavioral information — that incident updates are embedded in the response and ordered newest first — but says nothing about pagination, update volume, or missing/not-found behavior.

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 short sentence with no filler; the most decision-relevant fact (single incident, updates included) comes first. It is terse rather than padded, though the terseness edges toward under-specification.

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 two required, undocumented parameters, no output schema, and no explanation of identifier formats or error cases, the definition is not complete enough for reliable invocation. The one useful detail (updates ordered newest first) does not offset those gaps.

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% and the description never mentions the two required parameters. It gives no hint whether "slug" is an org/status-page slug or what format "public_id" takes, so an agent has no way to fill these fields correctly from the definition alone.

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?

"One incident" names the resource and its singularity, implicitly distinguishing it from the plural/list siblings, and "including updates newest first" adds scope detail. It lacks an explicit verb (fetch/retrieve), but the intent is unambiguous.

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 guidance on when to call this rather than update_incident, post_incident_update, or the proposal tools, and no mention of prerequisites such as needing an existing slug/public_id. The agent must infer the whole usage context.

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