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

With no annotations provided, the description carries full burden for behavioral disclosure. It states it 'gets' data (implying read-only), but doesn't mention any behavioral traits like pagination, rate limits, authentication requirements, or what happens when multiple optional parameters are combined. For a data retrieval 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 extremely concise at just 6 words ('Get FEC audit cases and findings'). It's front-loaded with the core purpose and contains no unnecessary verbiage. Every word earns its place in communicating the essential function.

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 4 parameters, no annotations, and no output schema, the description is insufficiently complete. It doesn't explain what 'audit cases and findings' actually means in practice, what data format is returned, or how the optional parameters interact. For a data retrieval tool with multiple filtering options, more context would be helpful for effective use.

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%, so all parameters are documented in the schema itself. The description doesn't add any parameter-specific information beyond what's already in the schema descriptions. According to scoring rules, when schema coverage is high (>80%), the baseline is 3 even with no param info in the description.

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 'Get FEC audit cases and findings' clearly states the verb ('Get') and resource ('FEC audit cases and findings'), making the purpose immediately understandable. It doesn't explicitly differentiate from sibling tools like 'get_filings' or 'search_candidates', but the specificity of 'audit cases and findings' provides inherent domain distinction.

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 no guidance on when to use this tool versus alternatives. With sibling tools like 'get_filings' that might overlap in data retrieval contexts, there's no mention of when this tool is appropriate or when other tools should be preferred. The description is purely functional without contextual usage information.

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

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 mentions 'Get links' but doesn't specify whether this is a read-only operation, if it requires authentication, what format the links are in (e.g., URLs, file paths), or any rate limits. For a tool with no annotation coverage, this leaves critical behavioral traits unaddressed.

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 a single, efficient sentence with zero wasted words. It's front-loaded with the core action and resource, making it easy to parse quickly. Every word earns its place, achieving optimal conciseness without sacrificing clarity.

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's moderate complexity (2 parameters, no annotations, no output schema), the description is minimally adequate. It states the purpose but lacks behavioral details, usage context, and output information. With no output schema, the description doesn't explain what 'links' entail (e.g., format, structure), leaving gaps that could hinder effective use.

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 schema description coverage is 100%, with clear descriptions for both parameters, including an enum for 'data_type'. The description adds no additional parameter semantics beyond what the schema provides, such as explaining the relationship between 'data_type' and 'election_year' or usage examples. Baseline 3 is appropriate given the schema does the heavy lifting.

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 clearly states the action ('Get links') and resource ('bulk data downloads'), making the purpose immediately understandable. However, it doesn't differentiate this tool from sibling tools like 'get_filings' or 'get_candidate_contributions' that might also provide data downloads, missing an opportunity for precise distinction.

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?
