A3.6/5.0
Behavior3/5

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

No annotations are provided, so the description carries the full burden. It does disclose the return shape (ID, price, ETA, author pubkey, text) and the empty-state behavior, and 'View' implies a read-only operation, but it never states permissions, identity requirements, ordering, or whether offers can be filtered by status.

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

Conciseness5/5

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

Two short sentences in a clean Args/Returns layout, front-loaded with the scope statement. No filler or repeated information.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a one-parameter read tool with an output schema present, the description covers scope, the argument's meaning, and the empty-result case. Minor gaps remain around ordering, pagination, and offer status, but nothing an agent needs in order to call it correctly is missing.

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 0%, so the description has to compensate for the single intent_id parameter. It explains that the ID selects 'the intent whose offers should be shown' and that non-owned intents are allowed, but gives no format or sourcing guidance for the ID, so the compensation is only partial.

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?

States a specific verb and resource (view offers) and clarifies the scope is any intent, not just the caller's own, which separates it from a4a_publish_offer. It stops short of naming a sibling alternative explicitly, so it is clear but not fully differentiated.

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

Usage Guidelines3/5

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

Usage is only implied: an agent infers it should call this after publishing an intent to review bids. There is no explicit when-to-use/when-not guidance and no reference to a4a_publish_offer, a4a_get_agreements, or a4a_search_intents as alternatives.

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