list_public_components

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

No annotations are provided, so the description carries the full burden. It discloses the filtering criteria (public and verified links) and the practical implication (clonable today), which is useful behavioral context. However, it does not mention whether the operation is read-only, any authentication requirements, or potential rate limits. For a simple list with no parameters, this is adequate but leaves some room for improvement.

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 two sentences with zero waste. The core purpose is front-loaded ('List only public components...'), and the second sentence adds a practical implication ('These are the repositories a user can actually clone today'). Every word earns its place.

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 tool has no parameters, no output schema, and is a straightforward list operation, the description is complete. It tells the agent exactly what the tool returns and the criteria for inclusion. No additional details are necessary for correct invocation.

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?

There are zero parameters, so the schema provides no parameter information. The baseline for 0 parameters is 4, and the description appropriately focuses on the tool's output criteria rather than parameters. It adds meaning about what the returned list contains, which is beyond the empty schema. No parameter explanation is needed.

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 uses a specific verb ('List') and resource ('public components') with a precise qualifier ('that carry verified repository links'). It clearly distinguishes from sibling tools like list_components (all components) and list_private_components (private ones), making the tool's unique purpose 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 provides clear context: it lists only public components with verified links, and adds that these are the repositories a user can actually clone today. This implicitly guides when to use it (when you need clonable repos) but does not explicitly name alternatives or state when not to use it. Given the sibling list, the differentiation is effective though not exhaustive.

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