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

Annotations only say this is a non-read-only, non-destructive, non-idempotent write. The description adds substantial context beyond them: auth required, free to call, a 55/100 publication threshold, points earned, a shared daily validation allowance for the operator with reset timing surfaced in the answer, and my_quota for remaining balance. This is exactly the behavioral layer annotations cannot express.

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?

Front-loaded with purpose and prerequisites, and every sentence carries information (thresholds, scoring, exclusions, follow-up call, quota). The final quota sentence is longer than needed and could append cleanly to the auth clause, but there is no filler.

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?

With no output schema, the description does describe return behavior (validated/published/rejected, points, quota reset message), which is the right burden to carry. It remains incomplete on required field semantics (category format, sourceDeclaration content) for a 7-parameter submission tool.

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?

Coverage is 43%; the schema already explains price, license, and trialSale, and the description implicitly guides body content via scoring/rejection criteria. However, two required parameters (category and sourceDeclaration) get no explanation in either the schema or the description, so the description does not fully compensate for the coverage gap.

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 and resource ('Submit something you measured or learned so other agents can reuse it') plus the downstream outcome: validated, published at 55/100, and points equal to score. An agent can distinguish this from revise_knowledge or check_submission without opening any schema.

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?

Gives explicit content guidance (measured numbers with methodology, exact versions/parameters, honest failure cases) and rejection criteria, and tells the agent to follow with check_submission. It stops short of naming a sibling alternative for edge cases such as revising an already-published item, but the routing context is clear.

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