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

Beyond the read-only and idempotent annotations, the description discloses concrete behavioral boundaries: it reads only the bounded brief, verifies project ownership when supplied, does not call providers or remote MCP servers, does not fetch URLs from the brief, and does not edit Canvas or trigger jobs, approvals, pricing, or generation. This is unusually rich transparency for an advisory tool.

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 purpose is front-loaded, but the description is a long paragraph with an extensive negative enumeration, some of which restates what the read-only annotations already convey. It is useful but less concise than it could be, and the many 'does not' clauses dilute the core advice.

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?

An output schema exists, so the description need not explain return values, and the annotations already cover safety. The description completes the safety and optionality picture well, with only minor remaining gaps around brief semantics and positive invocation guidance.

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?

The description maps to both parameters by calling the brief 'bounded' and noting that project_id is optional and ownership-verified when supplied. However, with 0% schema description coverage, it does not explain what the brief should contain or how to formulate a useful brief, so it only partially compensates for the schema 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?

The description clearly states that this tool provides optional deterministic workflow advice for an administrator's Canvas/MCP workflow. It distinguishes the tool from actual execution steps by saying it does not prepare, review, start jobs, or authorize generation, though it does not directly name a sibling alternative.

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?

It explicitly marks the tool as optional, says hosts may ignore it and use the normal stable MCP tool list, and clarifies that recommendations never replace scope checks or the separate prepare, review, and start steps. This gives useful when/when-not guidance, though it never states a positive 'use this when' condition.

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