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

With no annotations, the description carries the full behavioral burden, yet it says nothing about side effects, whether a new proposal is created, moderation/review, rate limits, or authentication (the api_key param hints at auth but the description never states it). For a content-creation mutation this is a significant gap.

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 short sentence that is front-loaded with the action and target, with no filler. It is efficient, though arguably too terse to be maximally useful.

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 mutation tool with no annotations, no output schema, and a partially documented schema, the description is too thin: it omits auth requirements, what creation entails, and the shape of the result. An agent has enough to guess the call but not enough to call it confidently.

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 75%, so the schema already documents title, body, and api_key, leaving only 'tags' undocumented. The description adds no meaning beyond the schema, so it neither compensates for the gap nor detracts; baseline 3 is appropriate.

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 gives a specific verb (suggest) and resource (improvement to the Haven proposals board), which lets an agent infer this is the create-side of the proposals workflow. It is distinguishable in nature from siblings like list_proposals and vote_proposal, though the parenthetical '(proposals board)' is slightly cryptic and it never explicitly names the sibling it complements.

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?

There is no when-to-use versus when-not-to-use guidance and no mention of alternatives such as vote_proposal or list_proposals. The only routing signal is the parenthetical 'proposals board', which implies context but doesn't state prerequisites or exclusions.

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