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

No annotations exist, so the description carries the full burden. It usefully discloses the default status filter and that results carry a dedup_key for downstream actions, but says nothing about ordering, pagination behavior, limits, or permissions. Adequate but with clear gaps for a list tool with zero annotation coverage.

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?

Two short sentences, front-loaded with the core action and scope, then the default, then the actionable follow-on hint. No filler text.

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?

An output schema exists, so return-value documentation is unnecessary, and the description still flags the one return field an agent must act on (dedup_key). With only two optional params and a documented default, the main remaining gap is limit/pagination semantics.

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. It explains the effective default of the status parameter ('only OPEN incidents'), but the limit parameter and the accepted status values are left entirely to the schema's enum/default. Partial compensation only.

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 ('List') plus resource ('incidents') and scope ('on the caller's account'), which separates it from describe_incident (single incident) and from the other list_* siblings by resource. The default-filter sentence adds precision about what the listing actually returns.

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?

Explicitly says it defaults to only OPEN incidents, so an agent knows the status filter must be widened to see acknowledged/resolved. It also names the follow-on tools (acknowledge_incident, resolve_incident) and the key needed to call them. It stops short of stating when to prefer describe_incident over this list.

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