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

With no annotations, the description carries the full burden, and it does disclose the key behavioral trait that no API key/auth is required. Beyond that it does not confirm read-only/non-destructive behavior, idempotency, or output format, so behavioral coverage is adequate but incomplete for a tool with zero annotation support.

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?

Front-loaded with the verb and subject, then a compact list of returned artifacts, ending with the concise 'No API key.' clause. It is a single dense sentence and slightly jargon-heavy, but every clause carries information and nothing is 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?

For a simple discovery tool with no parameters, no annotations, and no output schema, the description compensates by enumerating the artifacts it resolves, effectively standing in for missing return-value documentation. It lacks only explicit sequencing guidance for the onboarding path, which keeps it below a 5.

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?

The tool takes zero parameters, so there is nothing for the description to disambiguate; the baseline for a 0-param tool is 4. The enumerated resolved artifacts function as informal return-value semantics rather than parameter meaning.

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 ('Resolve') and a concrete resource (BaseAlpha platform artifacts), then enumerates exactly what it returns: MCP URL, stdio package, registry name, ERC-8004 identity, well-known registration, and the onboard path. This distinguishes it from the get_*/list_* siblings, which fetch operational data rather than discovery metadata. It stops short of naming an alternative tool, so it is clear but not sibling-differentiating.

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?

'No API key' and the 'apply → claim → launch onboard path' strongly imply this is the unauthenticated entry point to call first, which is useful implied guidance. However, there is no explicit when-to-use/when-not statement and no reference to a sibling such as apply_for_api_key as the next step, leaving the agent to infer sequencing.

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