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

Annotations already state readOnlyHint=false, destructiveHint=false, openWorldHint=false, idempotentHint=false, so safety basics are covered. The description adds nothing beyond them: no name-uniqueness behavior, no limit on projects per account, no statement of what is returned (project ID?) or whether the caller becomes owner.

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 efficient sentence with no filler. Brevity is appropriate, though it errs toward under-specification rather than over-verbosity.

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 mutation tool with a two-field schema, no output schema, and 0% parameter documentation, the description should say what gets created, what is returned, and any constraints. It covers only the one-line purpose, leaving the agent guessing about results and follow-up steps.

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% and the description never mentions the two parameters. It does not explain that 'name' is the required display name (1-80 chars) or what 'description' is for, so no compensation 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?

Clear specific verb+resource: 'Create a workspace project', with added purpose ('organize scientific work'). It doesn't need heavy sibling differentiation since none of the listed siblings create projects, though it never references list_projects or assign_project as follow-ups.

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?

No when-to-use guidance, no prerequisites, no mention of alternatives or follow-up tools (e.g., assign_project to add members). The agent must infer when a project is the right container versus a workflow.

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