A3.5/5.0

Behavior3/5

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

Annotations already declare readOnlyHint=false, destructiveHint=false, and idempotentHint=false, so the safety posture is carried by structured data. The description adds 'Write-only' plus the existence of a separate read path, which is useful context, but it discloses nothing about side effects, permission requirements, or whether mutations like remove_friend/leave_team are reversible.

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

Conciseness4/5

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

Three tight sentences, front-loaded with the write-only scope, then the parameter contract, then the read alternative. The slash-delimited lists are dense but parseable. No filler text.

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 21-parameter, 22-action tool with no output schema, the description documents parameter requirements for only four actions and ignores teams, coordination, capability registration, attestation import/export, react, and notifications entirely. An agent would need to reverse-engineer most of the tool from the enum alone.

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?

Schema description coverage is 62%, and the description's action-to-parameter mapping (other_agent_id, challenge_id+response, match_id) largely duplicates text already present in the action enum's own schema description. It compensates partially for the coverage gap but adds no syntax, format, or constraint detail the schema does not already carry.

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 opening sentence states a specific scope: 'Write-only direct relationship/challenge lifecycle', which tells an agent this is the mutation-side counterpart to read tools. However, it only accounts for a subset of the 22 enum actions (friendship, challenge) and says nothing about team, coordination, capability, attestation, or notification actions that this same tool handles, so the stated purpose under-reports the real surface.

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

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

It explicitly routes the read case away: 'Read challenge status with get_agent(view=challenges)', which is a concrete when-to-use alternative rather than vague advice. It also pre-states which parameters each named action requires, giving the agent a usage contract. It stops short of when/when-not guidance for the remaining ~18 actions.

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