nexus_abstain_endorsement

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

Annotations already signal destructiveHint=true and idempotentHint=false, so the mutation profile is known. The description adds minor context by identifying the affected resource as an endorsement and indicating the expected response status, but it does not explain consequences, reversibility, or authorization requirements beyond what annotations imply.

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 compact, front-loaded with the operation, and includes only the essential return-status information. Every sentence earns its place with no filler.

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 low-complexity, three-required-parameter tool with full schema descriptions, annotations, and an output schema, the description provides sufficient operational context. It would benefit from explicitly noting whether abstaining requires an existing endorsement or is irreversible, but nothing critical for invoking the tool is missing.

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 the parameters are fully documented in the schema itself. The description does not add extra semantics such as how abstaining relates to a specific version or what domain_name means, so it provides no additional value beyond the schema baseline.

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-resource pair ('withdraw or abstain from an endorsement') and names the target resource (a mod), which clearly communicates the core operation. It does not explicitly name a sibling alternative such as nexus_endorse_mod, but the semantic contrast is strong enough for an agent to distinguish the action.

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 when the tool should be used ('withdraw or abstain from an endorsement') but provides no explicit guidance about when to prefer it over nexus_endorse_mod or nexus_get_endorsements, nor any exclusions or prerequisites. This is usable but leaves the selection logic implicit.

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