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

Annotations already disclose readOnly=false, idempotent=false, destructive=false and a closed-world scope, so the safety profile is covered. The description adds only the workspace scoping detail; it does not mention whether duplicate names are allowed, whether the creator becomes owner, or what permissions are required for organization workspaces.

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?

A single front-loaded sentence with zero wasted words. Brevity here reflects correct structure, though it borders on under-specification rather than crispness.

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 return values need no explanation, but this is a non-idempotent mutation with four undocumented parameters and no annotations covering permissions or side effects. The description leaves too much for the agent to guess about a write operation.

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%, so the description must compensate. It partially does: 'personal or organization workspace' implies what workspaceId selects and that omitting it likely defaults to the personal workspace. It says nothing about the distinction between 'description' and 'instructions' or the 6000-character limits, so half the ambiguity remains.

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 a project') plus the scope ('personal or organization workspace'), which is enough to distinguish it from create_document and other siblings. It stops short of explicitly naming or contrasting with sibling tools such as update_project or list_projects.

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?

There is no guidance on when to use this tool versus siblings, no prerequisites (e.g., required role or permissions), and no exclusions. The agent must infer usage purely from the name.

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