A4.2/5.0

Behavior4/5

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

No annotations are supplied, so the description carries the burden, and it does disclose key traits: read-only listing, newest-first ordering, the fields each entry returns, and a hand-off to get_invention. It omits pagination behavior beyond the default limit and whether results are cached or rate-limited.

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?

Three compact sentences, front-loaded with purpose and ordering, followed by return shape and the sibling hand-off. No filler or repetition.

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?

An output schema exists, so return-value detail is largely covered and the description adds a useful summary anyway. Remaining gaps are minor: valid track values and the meaning/limits of limit, which matter for correct invocation of a low-complexity list tool.

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 coverage is 0%, so the description must compensate for two parameters. It explains track only as "optionally filter by track" without listing valid track values, and says nothing about limit, leaving the result-count parameter entirely to the schema default.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb and resource ("List the newest AgentWorld inventions"), plus the ordering ("newest first"). It also distinguishes itself from the sibling get_invention by explaining that a slug must be passed there for the full record.

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?

Gives clear usage context: use this for the newest overview, optionally narrow with track, and route to get_invention for details. It stops short of explicit when-not-to-use guidance or naming other listing alternatives, but the routing advice is concrete.

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