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

Beyond the annotations (readOnlyHint=false, idempotentHint=true, destructiveHint=false, openWorldHint=true), the description discloses that publication passes through ordinary moderation, that the call never confers verification, funding eligibility or payment rights, and that authentication is a custom bearer scope rather than OAuth. Those are exactly the non-obvious behavioral facts an agent needs, though the return value and moderation latency are not described.

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?

Three short sentences, front-loaded with the action and immediately followed by the critical scope-limiting caveats, with no filler. The dense phrasing around the auth scope ('MLAIEL bearer scope publish:project') is slightly jargon-heavy but still compact and functional.

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?

For a 10-parameter, 7-required creation tool with no output schema and no schema descriptions, the description covers behavior and auth well but leaves the entire parameter surface and the response shape undefined. An agent could call it correctly only by reading the raw schema field names, which is a meaningful gap for a creation 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?

The schema has 10 parameters with 0% description coverage, and the description says nothing about any of them. In particular, the required 'requestId' and the idempotentHint imply an idempotency-key convention, and the required narrative fields (problem, audience, whyItMatters) have length constraints, but none of this is explained, so the description does not compensate for the coverage gap at all.

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 uses a specific verb and resource ('Submit an AI project') and scopes the outcome ('for public collaboration after ordinary moderation'), so an agent knows this publishes rather than drafts. It does not explicitly contrast with the sibling 'create_project_draft', so the boundary between submitting and drafting is left to inference.

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 states the precondition for calling (a pre-provisioned MLAIEL bearer scope 'publish:project') and implies the post-condition (ordinary moderation), which implies when the tool is appropriate. However, it gives no explicit when-to-use versus 'create_project_draft' or 'edit_own_project', and no guidance on what to do when the scope is missing.

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