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

No annotations are provided, so the description bears the full disclosure burden. It does add genuinely useful behavior: billing at each service price, €0 for setup, and authentication via 'Authorization: Bearer' API key. However, it says nothing about whether the returned configs embed credentials, whether the call is read-only, or what happens with no services configured.

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 purpose appears in the second sentence, after a preamble about Finekot's overall architecture that is context rather than tool-specific instruction. The description ends with a broken artifact ('Parameters — .'), which is wasted text. The billing and auth sentences do earn their place, so it is only moderately front-loaded.

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 zero-parameter tool with an output schema already present, the description covers what an agent needs: what is returned, which clients are supported, that it is free to run, and how it is authenticated. Gaps are minor — mainly the relationship to the 'services' sibling and whether a pre-existing API key is mandatory.

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 the baseline is 4 and the schema has nothing to explain. The trailing fragment 'Parameters — .' is an empty placeholder that adds no meaning but also does not mislead. Nothing further is required of the description here.

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 deliverable: 'This call returns ready configs for Claude Code, Claude Desktop, Cursor and VS Code.' That is a concrete verb+resource an agent can act on. It never distinguishes itself from the sibling tools 'services' and 'account', which cover adjacent territory, so sibling differentiation is missing.

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?

There is no statement of when to call this tool versus the similar-sounding 'services' or 'account' siblings, and no prerequisites or exclusions. The only guidance offered is pricing ('Cost €0 per setup'), which is not usage guidance. An agent must infer the trigger condition from the purpose sentence alone.

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