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

The readOnlyHint/openWorldHint annotations already declare this as a safe, non-external read, so the bar is lower. The description earns credit by disclosing the possible return states and the conditional live-link field (no output schema exists to carry that), though it says nothing about behavior for an unknown or unauthorized release_id.

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 sentences, front-loaded with the resource and the state enumeration, followed by one sentence of usage context. No filler, nothing repeated from the title or annotations.

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?

With no output schema, the description usefully enumerates the status values and the published link, which is the core of what an agent needs to interpret the response. It omits error/not-found behavior and scoping (account/workspace), which keeps it shy of complete.

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?

There is a single required parameter with 100% schema description coverage, so the schema carries the definition. The description adds nothing about release_id format, source, or whether it must belong to the caller's account. Baseline 3 is correct when the schema does the heavy lifting.

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 gives a specific resource (a press release) and enumerates exactly what it returns: draft, pending review, scheduled, live, plus the live link once published. That distinguishes it in practice from list_releases (plural, all releases) and publish_release (a mutation), though it never names a sibling explicitly.

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?

"Useful to check back on a release that was waiting for review" implies a polling/status-check use case, but there is no explicit when-to-use vs. when-not, and no alternative named (e.g., use list_releases to see all statuses at once). Usage is implied rather than stated.

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