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

No annotations are provided, so the description carries the full behavioral burden, yet it discloses nothing about ordering, pagination, scope (all repos vs. user-specific), or authentication. An output schema exists, which covers return values, but the invocation-side behavior is entirely undocumented.

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, front-loaded sentence with no filler or redundancy. It is appropriately sized for a zero-parameter list tool, though 'known to Dibs' is marginally ornamental rather than informative.

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 trivial zero-param list call, the description is minimally sufficient and the output schema covers the return shape. It stops short of stating scope or pagination behavior, which would be cheap to add and would remove the remaining ambiguity.

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 tool takes zero parameters, so there is nothing to document and the baseline is 4. The description neither misleads nor needs to compensate for any schema gap.

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?

States a specific verb (List) and resource (registered repository venues), which is unambiguous against the idea-centric siblings (get_idea, list_my_ideas, submit_idea). The phrase 'known to Dibs' names the owning system, though it is slightly jargon-heavy. No explicit sibling differentiation is given, but none is needed given the disjoint domains.

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 contains no when-to-use guidance, no prerequisites, and no mention of alternatives. The agent must infer the tool's applicability purely from the name. This matches the 'no guidance' tier.

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