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

Annotations already declare destructiveHint=true, idempotentHint=true, and readOnlyHint=false, so safety and repeat-call behavior are covered. The description adds one piece of context beyond annotations — that only user-created tags are deletable — but says nothing about irreversibility or what happens to articles carrying the tag.

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 front-loaded sentence with no filler; the verb and key come first. It is efficient, though very terse for a destructive mutation, bordering on 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?

For a single-parameter delete tool whose annotations already carry the destructive/idempotent profile and with no output schema, this is roughly adequate. It omits any note on side effects (e.g., tag removed from associated articles), leaving a minor gap for a mutation.

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 coverage is 100% and the single parameter (tag_id) is documented in the schema as 'The tag ID to delete.' The description adds no format, sourcing, or lookup guidance beyond confirming the ID key, so the baseline 3 applies.

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 (Delete) and resource (user-created tag) and the identifying key (ID), so an agent can distinguish it from create_tag and get_tags. The 'user-created' qualifier usefully implies system tags are out of scope, but it does not name a sibling or alternative route.

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 explicit when-to-use, prerequisites, or alternatives are given. The 'user-created' phrasing implicitly signals that system/protected tags cannot be targeted, and the destructive nature of the operation is obvious from the verb, but usage is left to inference rather than stated.

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