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

Annotations already declare destructiveHint=true, idempotentHint=true, and readOnlyHint=false. The description adds genuinely new context by stating 'Release cannot be reversed', which qualifies the irreversibility beyond the destructive flag, and reiterates the teacher-approval gate. It does not disclose rate limits or downstream effects, but it usefully supplements the annotation profile.

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?

Two compact sentences with the action and the binding identifier front-loaded, followed by the approval condition and irreversibility warning. No filler.

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-reversible mutation with rich annotations and an output schema, the description covers the action, the gate, and the irreversibility. It is sufficient; only the explicit link to prepare_release_results as the preceding step is missing.

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 schema already documents previewId's origin and length constraints, so the baseline is 3. The description adds a meaningful nuance by calling the previewId 'owner-bound', signaling scoping/authorization semantics not present in the schema.

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 states a specific verb ('releases results') tied to a specific resource and keyed identifier ('owner-bound previewId'), which is clearly distinct from the sibling prepare_release_results. It does not explicitly name the sibling, but the action is unambiguous.

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?

It states a precondition ('subject to explicit teacher approval of that specific preview'), which implies this is a post-approval step, and the parameter description references the 'matching prepare_ tool'. However, it never explicitly says to use prepare_release_results first or names any exclusion, leaving the routing largely to inference.

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