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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and openWorldHint=false, so safety is covered structurally. The description adds a detailed data-handling disclosure (what is stored, what is hashed, what is never collected), which is useful context beyond the annotations, but it says nothing about pagination or result shape.

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 core purpose is front-loaded, but the first sentence is a heavily parenthesized run-on whose vertical list largely duplicates the category enum, and the closing privacy block is long. The essential routing information (get_exit_plan) is buried in the middle rather than surfaced early.

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?

There is no output schema, yet the description only gestures at returns with 'the page and JSON for each' and never explains pagination or how limit interacts with results. For a zero-required-parameter browse tool, the purpose and privacy aspects are covered but the calling contract is thin.

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 only 33%: 'query' is documented in the schema, 'limit' is not described anywhere, and 'category' relies on a self-explanatory enum. The description maps loosely to query/category ('by name, domain or category') but never explains limit or default behavior, so it only partially compensates for the gap.

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 (lists) and resource (services in Stackcut's cancel library), enumerates the searchable axes (name, domain, category), and explicitly separates itself from the sibling get_exit_plan. An agent can distinguish it from get_exit_plan without opening either schema.

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?

Gives an explicit alternative and the condition that selects it: 'Use get_exit_plan for one service's steps.' That is real routing guidance. It does not mention other plausible siblings such as list_categories or find_alternatives, so it falls short of a full when/when-not map.

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