flutter_list_samples

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It describes what the tool does (browse/filter) but says nothing about pagination, result volume, return format, or any limits. For a browsing tool that likely returns a large index, this is a meaningful disclosure gap, though the core behavior is adequately conveyed.

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?

A single efficient sentence that conveys purpose and the optional filtering capability with zero waste. It's appropriately brief for a simple one-parameter tool, though it could arguably include a touch more usage context without becoming verbose.

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 browse/filter tool with one enum-constrained optional parameter and no output schema, the description is mostly adequate. However, it doesn't mention what the returned results look like (given no output schema exists) nor does it clarify the relationship to sample-fetching siblings, leaving the agent partially guessing about downstream behavior.

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 100%, with the single 'category' parameter already documented in the schema including a full enum of valid values. The description adds the 'optional' qualifier, confirming the parameter isn't required, but adds little beyond what the schema provides. The baseline 3 applies since the schema does the heavy lifting adequately.

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 ('Browse') with a clear resource ('advanced sample corpus index') and a scoping qualifier ('optionally filtered by category'). It clearly indicates this is a listing/browsing tool. However, it doesn't explicitly distinguish it from the sibling tools like flutter_find_sample or flutter_get_sample, which could be confused for related sample-access operations.

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 a browsing use case ('Browse... optionally filtered by category') but provides no explicit guidance on when to choose this over flutter_find_sample or flutter_get_sample. Since these siblings likely handle searching and retrieving specific samples, usage context is implied but not stated.

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