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

No annotations are provided, so the description carries full burden. It states a read operation ('List'), implying non-destructive behavior, but doesn't disclose critical traits like authentication requirements, rate limits, pagination details (implied by 'page' and 'page_size' parameters but not explained), or what the output looks like (e.g., list of usernames). This leaves significant gaps for a tool with 6 parameters.

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 waste—it directly states the tool's function without fluff. It's appropriately sized for a basic listing tool, though its brevity contributes to gaps in other dimensions.

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 complexity (6 parameters, no annotations, no output schema), the description is incomplete. It doesn't explain parameter usage, output format, or behavioral constraints. For a tool that likely involves API calls with pagination and filtering, this leaves the agent under-informed about how to invoke it effectively.

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. It mentions 'repository' which maps to 'owner' and 'repo' parameters, but adds no meaning for the other 4 parameters (sort, exclude_bots, page, page_size). This fails to explain what these parameters do or how they affect the listing, leaving them undocumented.

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 issue creators for a repository' clearly states the verb ('List') and resource ('issue creators'), but it's vague about scope—does it list all creators, recent ones, or those with specific criteria? It distinguishes from siblings like 'list_pull_request_creators' by focusing on issues, but lacks specificity on what 'issue creators' entails (e.g., users who opened issues).

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. It doesn't mention prerequisites (e.g., repository access), exclusions, or how it differs from siblings like 'issue_creators_countries' or 'repo_issue_creators_history', leaving the agent to infer usage from the name alone.

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