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

The annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and openWorldHint=false, so the safety profile is fully covered structurally. The description adds real value by disclosing that the response bundles attached tasks alongside release metadata, but it never explains how the optional taskStatus filter alters that bundle or whether the task list is bounded/paginated.

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 front-loaded sentence with a parenthetical field list and an 'plus its attached tasks' addendum — no filler and nothing repeated. It is slightly dense in the parenthetical, which is why it is not a perfect 5.

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 simple, read-only single-record fetch with a fully documented schema and no output schema, the description covers what is returned (notes, dates, color, tasks) well enough for an agent to call it correctly. The only meaningful gap is the unstated behavior of the taskStatus filter and whether the attached-task list can be large.

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 description coverage is 100%, so the baseline would be 3, but the description contributes no meaning to any parameter — it does not clarify the 'active' vs 'done' vs 'all' semantics of taskStatus or how projectId scopes the lookup beyond the schema's bare 'The project ID'. The mention of 'attached tasks' is the only link to taskStatus and it is indirect, landing below the baseline.

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 names a specific verb and resource ('Get one release's details') and enumerates the payload (public release notes, dates, color) plus the attached-task list, so it is clearly a single-release fetch. It does not name siblings such as list_releases or release_read_active, so the differentiation is only implied by 'one release'.

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?

Requiring a specific releaseId and the phrase 'one release' implicitly signals this is the single-record read rather than a listing, which is adequate guidance. However, nothing states when to prefer it over list_releases or the similarly named release_read_active sibling, and there are no exclusions or prerequisites beyond what the schema mandates.

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