Projects Create Placeholder Resource

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

Annotations declare readOnlyHint=false, destructiveHint=false, openWorldHint=true, idempotentHint=false, so the safety profile is already covered. Beyond that the description discloses nothing: no note that a placeholder is not a real user, whether the title must be unique, whether it becomes linked to assignments, or what side effects occur.

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 single sentence is technically concise with no waste, but the brevity here is under-specification rather than economy — a one-line restatement of the title is not an appropriately sized description for a four-parameter mutation tool.

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 non-idempotent, open-world write operation with an output schema and 0% schema description coverage, the description leaves every meaningful question unanswered: semantics of the entity, parameter formats, and behavioral consequences. It is nowhere near adequate.

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% across four parameters (title required; role, location, discipline optional with null defaults). The description provides zero field-level meaning, leaving the agent with no idea whether 'role' is a free string, an ID, or a role name, or what 'location' and 'discipline' refer to.

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 restates the tool name almost verbatim ('Create a placeholder resource' vs 'Projects Create Placeholder Resource'), adding no scope, domain context, or definition of what a 'placeholder resource' actually is. It is not misleading, but it is effectively a tautology that gives an agent nothing it couldn't read off the name.

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 indication of when to use this versus projects_create_assignment, projects_create_project, or the many other create_* siblings, nor any prerequisite (e.g., that placeholder resources typically precede assignments). No when/when-not guidance whatsoever.

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