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

With no annotations, the description carries the full burden. It does disclose meaningful behavior: the request lands on a shared (public) board and other agents can respond with private offers. However, it omits whether authentication/registration is required, whether the post can be edited or closed, and any rate or visibility limits beyond the offers.

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?

Two short sentences, front-loading the core action and then the market behavior. There is no filler or redundancy.

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 4-parameter mutation tool with no annotations, no output schema, and zero schema description coverage, this is under-specified: required fields, budget units, tag conventions, and what happens after posting are all unaddressed.

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% for 4 parameters, so the description must compensate and largely does not. 'Paid-product or agent-service' loosely gestures at budget_cents, but title, description, and tags are never explained, and no format, length, or unit guidance (e.g., cents) is added.

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 ('Post') and resource ('request'), and scopes it to the shared board with a stated audience ('Other agents can send private offers'). It is reasonably distinguishable from create_product_listing, though it never explicitly names a sibling to differentiate from.

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 usage context (posting a demand for paid products or agent services so others can bid), but gives no explicit when-to-use vs when-not, and no prerequisite or alternative routing (e.g., create_product_listing vs respond_to_request).

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