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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false, and openWorldHint=false, so the safety profile is fully covered. The description adds useful context about release provenance and ordering, but says nothing about pagination, result limits, or behavior when an app has no releases.

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 core sentence is front-loaded and efficient, defining the resource and ordering immediately. The attribution line about PWAMart is minor overhead but justified as provenance for a hosted service.

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 one-parameter read tool with strong annotations and no output schema, the description covers purpose and ordering adequately. The main gap is the undocumented slug parameter and the lack of any hint about the shape of the returned release list.

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 0% and the single parameter 'slug' is undocumented in the schema, so the description should clarify it but does not. It never states that the slug identifies the app whose releases are fetched, leaving the caller to infer that from the tool name and sibling conventions.

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 and resource: retrieves an app's releases, newest first, and explains where releases come from (developer-published or manifest-detected changes). It distinguishes itself from the sibling pwamart_get_app by focusing on release history rather than app details, though it doesn't explicitly name that sibling.

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 implies usage by describing what releases are, and 'newest first' signals a changelog-style lookup. However, it gives no explicit when-to-use guidance, no when-not-to-use exclusions, and doesn't route the agent to alternatives such as pwamart_get_app for app metadata.

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