fetch_components

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

With no annotations provided, the description carries full burden but offers minimal behavioral insight. It implies a read-only list operation but doesn't disclose pagination behavior (e.g., default values, limits), authentication needs, rate limits, error conditions, or return format. For a list tool with zero annotation coverage, this leaves significant gaps in understanding how it behaves.

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 very concise with two sentences, front-loading the core purpose ('List components') and briefly noting parameters. There's no wasted text, though it could be structured more clearly (e.g., separating purpose from parameter notes).

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 no annotations, 0% schema coverage, no output schema, and a simple list operation with 2 parameters, the description is incomplete. It lacks details on pagination behavior, return format, error handling, and differentiation from siblings, making it inadequate for reliable tool selection and 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?

Schema description coverage is 0%, so the description must compensate but only partially does. It mentions 'Optional per_page, page' but doesn't explain what these parameters mean (e.g., per_page controls items per response, page selects result page), their expected formats, default values, or constraints. This adds minimal value beyond the bare schema.

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 'List components' states the verb (list) and resource (components), making the basic purpose clear. However, it doesn't differentiate from sibling tools like 'get_component' (singular retrieval) or 'fetch_component_folders' (different resource type), leaving room for ambiguity about scope and relationship to other fetch tools.

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 guidance is provided on when to use this tool versus alternatives. The description doesn't mention sibling tools like 'get_component' for single-component retrieval or 'fetch_component_folders' for folder-level operations, nor does it specify prerequisites, contexts, or exclusions for usage.

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