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

Annotations already declare readOnlyHint=true and destructiveHint=false, so the safety profile is covered; the description still adds value by framing it as a status call with no Apple writes and by explaining the lost-response recovery workflow. It doesn't describe the shape/pagination of returned operation records, but the output schema handles that.

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 tight sentences, front-loaded with the read scope, then the recovery recipe, then the reassurance about no writes. Each sentence carries distinct information with no redundancy.

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 an output schema present and full annotation coverage, the description supplies the one thing structured fields can't: the retry/recovery workflow that motivates the call. Only minor gaps remain, such as whether multiple stored operations can be listed versus a single lookup by key.

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% and both project_id and request_key are fully documented in the schema, so the description need not carry parameter detail. It reinforces request_key retry semantics but adds nothing the schema lacks, matching the baseline for complete schema coverage.

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?

States a specific verb (read) and resource (saved publish/metadata/review/TestFlight requests), enumerating the operation categories it retrieves. It is clear enough to differentiate this record-retrieval tool from artifact-readers like get_metadata, get_review, and get_testflight, though it never names those siblings to sharpen the distinction.

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 gives concrete when-to-use conditions: recover a lost response or request_key, and resume pending work by re-invoking the original tool with the returned key. It stops short of explicit exclusions or naming the alternative tools to use for other cases.

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