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

Annotations already declare readOnlyHint=false, destructiveHint=false, and openWorldHint=false, so the write-but-non-destructive profile is covered structurally. The description adds genuinely useful context that the created project is 'empty' (no tables/workflow included) and that the ID and slug are the outputs. It omits permissions/auth requirements, whether the name must be unique, and what happens on a duplicate name.

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?

Two short sentences with zero filler, and the core action is front-loaded before the return-value note. Every clause carries information.

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 explaining return values is optional (and briefly done anyway), and annotations cover the mutation safety profile. The remaining gap is the undocumented 'name' parameter and the absence of any note on duplicate names or permissions, which matters for a create tool with 0% schema coverage.

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 0% for the single 'name' parameter, so the schema supplies only type and length bounds (2-100) with no semantic guidance. The description never mentions the name argument, its uniqueness, or any naming constraints, so it fails to compensate for the coverage 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?

States a specific verb and resource ('Create an empty project') plus the account scope, which is more than a tautology. It also situates the tool relative to downstream objects ('table and workflow setup'), though it never names a sibling tool it must be chosen over.

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?

The phrase 'for subsequent table and workflow setup' implies this is the prerequisite step before tables.create and workflow.setup, which gives the agent sequencing context. However, there is no explicit when-to-use statement, no when-not condition, and no named alternative, so the guidance remains inferred.

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