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

With no annotations, the description carries the full burden of behavioral disclosure. It does explain that miss_json and recovery_json are the same bodies posted to alert_url and that Slack/Discord receive only their relevant field, but it never describes what calling list_templates actually does, returns, or whether it has side effects.

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?

The description is short and does not waste words, but the opening phrase is grammatically awkward and the structure is unfocused. Valuable context about alert bodies and integration behavior is buried without a clear statement of the tool's core function.

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 simple list tool with no parameters and no output schema, the description should at minimum say what is being listed and what the response contains. Instead it discusses alert payload semantics and omits the only information an agent needs to correctly understand the tool.

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?

The tool has zero parameters, so the schema imposes no burden. The baseline of 4 applies: the description cannot add parameter semantics because there are no parameters to document, and no ambiguity is introduced.

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 uses 'Ingest snippets and the JSON HookPulse POSTs on a miss' without ever naming a list, a template, or a return value. It suggests the tool exists to prevent guessing the alert format, but does not clearly state that it lists templates. The relationship between the name and the description is left to inference.

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 is given on when to call this tool versus alternatives such as list_endpoints, list_events, or create_endpoint. The sentence 'It exists so nobody guesses the alert format' hints at a purpose but not at conditions or exclusions for use.

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