TDQS

C2.9/5.0
Behavior2/5

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 context. It doesn't mention whether this is a read-only operation (implied by 'Get'), rate limits, authentication requirements, or what the return format looks like (e.g., list of posts with titles, scores, etc.).

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single, efficient sentence that directly states the tool's purpose without any unnecessary words. It's perfectly front-loaded and wastes no space.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a tool with no annotations and no output schema, the description is insufficient. It doesn't explain what 'hot' means algorithmically, what data is returned, or any behavioral constraints. Given the context of multiple sibling tools with different sorting methods, more completeness is needed.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The schema has 100% description coverage, providing clear documentation for both parameters. The description adds no additional parameter semantics beyond what's already in the schema, so it meets the baseline of 3 for adequate coverage without adding value.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the action ('Get') and resource ('hot posts from a specific subreddit'), making the purpose immediately understandable. However, it doesn't explicitly differentiate from siblings like 'get_subreddit_new_posts' or 'get_subreddit_top_posts', which would require mentioning the 'hot' sorting algorithm specifically.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

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 siblings like 'get_subreddit_new_posts' and 'get_subreddit_top_posts' available, there's no indication that this tool retrieves posts sorted by Reddit's 'hot' algorithm rather than other sorting methods.

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