hcloud_list_alarms

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

Annotations already declare readOnlyHint=true, idempotentHint=true, and openWorldHint=true, so the safety profile is covered. Beyond expanding 'CES' to 'Cloud Eye', the description adds nothing: it does not say whether results are region-scoped, whether alarm state/severity is included, or how pagination behaves with 'limit'.

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?

Four words, front-loaded with the verb and resource, with zero filler. It is efficient, though the brevity edges toward under-specification rather than crispness.

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 read-only list tool with full schema coverage and annotations supplying the safety profile, an output schema is not needed and the core call path is intact. The remaining gap is disambiguation from hcloud_list_alarm_rules, which the description never addresses.

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 100%, so both 'region' and 'limit' are already documented in the schema, which sets the baseline at 3. The description adds no meaning beyond that, such as whether region is required for multi-region accounts or what the default limit is.

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 pairs a specific verb ('List') with a specific resource ('CES (Cloud Eye) alarms') and expands the acronym, so the object is identifiable. However, the sibling set contains hcloud_list_alarm_rules, and nothing here distinguishes an alarm from an alarm rule, leaving the agent unable to pick between the two without outside knowledge.

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 guidance on when to use this tool, no exclusions, and no reference to any alternative such as hcloud_list_alarm_rules or hcloud_show_metric_data. The agent must infer usage context entirely from the name.

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