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

Annotations only declare it as a non-readonly, non-destructive, closed-world mutation. The description adds genuinely useful behavior beyond that: returns 202, a human fetches/checks it and re-runs the pipeline, plus payment mechanics ('own receipt, never from a prepaid balance'). Some pricing/jargon content dilutes it and the post-review outcome stays vague, so not a 5.

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-loads the purpose in the first clause, which is good. It then compresses purpose, behavior, pricing, and cross-tool routing into one dense block; the 'Priced B4 (human work)... $49.00' detail is relevant but adds density that slightly hurts readability.

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 the work of explaining the async outcome (202, human review, check_status tracking) and cost implications. It stops short of clarifying what a rejected or accepted submission means in practice, leaving a minor gap for a 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?

Schema description coverage is 100%, so the schema already documents all five parameters (url, slug, type, contact, context). The description adds no syntax or format detail beyond the schema, so baseline 3 applies.

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 action and resource: publishing an artifact by submitting it rather than waiting for discovery. The phrase 'rather than waiting for us to find it' implicitly distinguishes it from find_artifacts/generate_artifact siblings, though no sibling is named explicitly.

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 clear context (submit an artifact you publish) and routing: 'Track it with check_status' for follow-up and 'report_correction is free' for the wrong-data case. No explicit when-not guidance or named alternative submission path, but the intended usage is unambiguous.

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