Delete comment

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

Annotations already declare destructiveHint=true, idempotentHint=false, and openWorldHint=true, so the safety profile is covered. The description's real contribution is the authorization rule — you may delete your own comment, or any comment on a track you own — which is genuinely beyond what annotations convey. It still omits irreversibility/confirmation and error behavior when the comment is missing.

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?

One short sentence with the scope constraint front-loaded; nothing wasted. It is arguably under-specified rather than over-long, but structurally clean.

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 destructive, non-idempotent mutation with three required parameters and no output schema, the description gives the permission model but not the failure/return semantics (no-op vs error on a nonexistent comment) or any warning about permanence. Adequate to pick the tool, thin for calling it confidently.

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 67% and the description says nothing about track, author, or comment_id. The uncovered parameter is comment_id, the single identifier that determines which record is destroyed, so the description leaves the most consequential input undefined in both schema and prose.

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?

Specific verb + resource ("Deletes a comment") with a scope qualifier that distinguishes deleting your own comment from deleting any comment on a track you own. It is clearly distinguishable from the sibling post_comment. The phrase "of the account" is slightly awkward, but the parenthetical resolves it.

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?

The description states what may be deleted but never says when to use this versus an alternative (e.g., moderation workflows, or what to do if the wrong comment id is supplied). No exclusions, prerequisites, or confirmation guidance are given for an irreversible operation.

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