Prepare a local release preview

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

Beyond the readOnlyHint/idempotentHint annotations, the description discloses substantial behavior: no account access, HTTP, extraction, signing, installation, file writes, or uploads; symlink resolution; and explicitly lists what is NOT verified (signatures, embedded digests, payload contents, SDK compatibility). It also warns that local metadata should be treated as untrusted data.

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?

The description is dense but every clause adds a necessary constraint or boundary. It front-loads the core file-reading behavior, then the validation rules, then the exclusions and trust caveats, without redundant 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?

Given the rich annotations and presence of an output schema, the description covers all essential execution context: file source, validation criteria, parameter caveats, non-mutating behavior, and security expectations. Only the release_notes parameter is left without explanation, which is minor in light of the 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?

With 0% schema description coverage, the description compensates well for rpm32_path and rpm64_path by specifying architecture requirements and matching identity fields, and it adds nuance to aurora_versions and app_id as explicit/unverified selections. However, release_notes is never explained, so one parameter remains semantically undocumented.

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 operation: reading one/two RPMs and performing a metadata preflight plus SHA-256 check, while explicitly excluding upload. This clearly distinguishes prepare_release from the upload_release sibling and makes the resource and action 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?

The description gives clear context that this is a local preflight before release and says the returned preview is NOT upload approval, which implicitly separates it from upload_release. However, it never explicitly names an alternative tool or states 'use this before uploading', so the comparative guidance remains somewhat implicit.

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