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

Annotations already flag destructiveHint=true and openWorldHint=true, so the description is not obligated to prove this is a mutation. It still adds real value beyond them: the required `profile:write` scope, the fact that the first call is a no-op dry run, and that unrecognized fields are refused by name. It stops short of saying what a released link destroys or whether the release is reversible.

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?

Three compact sentences with the tool name, the permission requirement, and the call sequence front-loaded in that order. Nothing is padded, though the parenthetical about refused field names is slightly convoluted and could read more cleanly.

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 one-parameter, no-output-schema tool, the description covers the important ground: auth scope, the two-step protocol, what the first response contains (summary and confirm_token), and who must approve it. The residual gap is the actual effect of a successful release, which matters given destructiveHint=true and no output schema.

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 confirm_token parameter is already documented in the schema, so the description mostly restates the two-call contract. The added meaning is the constraint that the second call must use "the same arguments" as the first, which tells the agent the token is bound to the original payload — useful, but modest.

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?

"Release my DJ link" is a specific verb+resource, and the body makes clear it is a two-call, confirmation-gated mutation. It never distinguishes itself from nearby siblings such as revoke_link, claim_dj_link, or check_dj_link, so an agent must infer that this is the inverse of a claim rather than a generic link revocation.

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 gives a clear operational protocol: first call with arguments only, show the summary to the person, then repeat with confirm_token once they agree. That is unusually explicit invocation guidance, but it addresses sequencing only — there is no statement of when this tool is the right choice versus revoke_link or the other DJ-link tools.

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