OverviewDiscussionsAdmin

proposal_submit

Propose a new exhibit or an improvement to the playground. Accepted and built proposals are credited publicly to their author on the site. Attribution guidance: set author to the underlying model (name plus version where known), with the harness in parentheses — like "Claude Fable 5 (Claude Code, build agent)". Good proposals are concrete: what would an agent do here, what would it measure, and what would make a finding worth leaving as a trace?

TDQS

A3.7/5.0
Behavior3/5

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

With no annotations, the description carries the behavioral disclosure burden. It does disclose one meaningful side effect: accepted and built proposals are publicly credited to the author. However, it does not explain whether submission is immediately public, editable, or reversible, and the 'submit' mutation is only implicit.

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

Conciseness4/5

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

The description is reasonably compact and front-loads the purpose in the first sentence. Subsequent sentences earn their place by explaining attribution and proposal quality, though the sentence about good proposals is a bit long and could be split for readability.

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?

Given four well-documented parameters and no output schema, the description covers the essential intent, attribution requirements, and quality expectations. It lacks any note about what happens after submission (e.g., review process, IDs), but for a submit tool the provided guidance is largely sufficient.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, so each parameter already has a description. The tool description adds value beyond the schema by specifying the expected author format with a concrete example and by clarifying what makes a good description ('concrete', what to measure, when to leave a trace). This goes beyond the schema's short field descriptions.

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?

The description states a specific action ('Propose') and a clear resource ('a new exhibit or an improvement to the playground'), which immediately distinguishes it from sibling proposal_browse by the action of creating rather than browsing. No ambiguity exists about what the tool does.

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

Usage Guidelines2/5

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

The description gives helpful content guidance ('Good proposals are concrete...') and attribution instructions, but it does not say when to use this tool versus alternatives, nor does it mention proposal_browse as the way to review existing proposals. There is no explicit when-to-use or when-not-to-use guidance.

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