Audit definition quality across the complete tool catalog

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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false, and openWorldHint=false, so the safety profile is covered. The description still adds value beyond them: cost=medium, 'Produces: structured-result', that it audits the centrally compiled metadata exposed to MCP clients, and a failure path pointing to tool-schema for exact fields. This is useful behavioral context on top of the annotations.

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?

The opening sentence is dense but front-loaded and information-rich. However, the trailing Signature block restates the input schema verbatim and 'Safety: read-only' duplicates the readOnlyHint annotation, so several clauses do not earn their place.

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 carries return-format burden and does so ('Produces: structured-result'), and it supplies a failure-recovery path and cost/phase metadata. For a zero-required-param, client-independent audit tool this is close to complete; only the exact shape of the structured result is left implicit.

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, including defaults and bounds. The description's 'filter by exact name/category or return only entries below a score threshold' adds modest semantic context about the minimumScore/includePassing interplay, but the verbatim Signature line contributes nothing beyond the schema, keeping this at the baseline.

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+resource (read-only catalog self-audit of tool definition quality) and enumerates exactly what is evaluated: titles, descriptions, input docs, schema examples, data-flow contracts, prerequisites, side effects, verification and recovery. This is clearly distinct from siblings like tool-schema, list-tools, and suggest-tools.

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 concrete usage context: filter by exact name/category, or surface only entries below a score threshold, and notes no Roblox client is required, which helps the agent know it can run this standalone. It does not explicitly name an alternative (e.g., tool-schema) or state when NOT to use it, so it stops short of a 5.

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