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

Annotations already declare destructiveHint=true and openWorldHint=false, so the safety bar is lower. The sentence 'Assets are kept' adds a genuine behavioral note (asset records survive project removal/deletion), but it is ambiguous about which action it applies to, and the description says nothing about the required idempotency_key, confirmation flow, or reversibility of delete.

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, front-loaded with the action list, with zero filler. It is concise, though the second sentence ('Assets are kept') is terse to the point of ambiguity.

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?

A destructive, multi-action mutation tool with 8 undocumented parameters and no output schema needs far more: per-action required fields, idempotency semantics, and what delete actually removes versus preserves. The single clause about assets does not close that gap.

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 8 parameters, so the description carries the full burden and fails to. It never explains the required idempotency_key, the role enum (asset vs key), the conditional nature of project/name/assets per action, or the 100-item asset cap.

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 names a specific resource (project folder) and enumerates all five supported operations (create, rename, delete, add/remove assets), matching the action enum exactly. It implicitly separates itself from creative_projects_list by being the mutation counterpart, though it never names that sibling explicitly.

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 guidance on when to choose this over creative_projects_list, no prerequisites or permissions, and no indication of which parameters apply to which action. An agent must reverse-engineer usage from the enum alone.

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