Project Update Theme

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

With no annotations, the description carries the full burden of behavioral disclosure. It implies mutation but says nothing about whether the change is reversible, whether it invalidates existing renders, what permissions are required, or what "render settings" are affected.

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?

It is a single, non-redundant sentence with the verb front-loaded, so there is no padding. However, the brevity comes at the cost of under-specification rather than efficiency.

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 not be explained. But for a mutation tool with zero annotations, a free-form nested object parameter, and 0% schema coverage, the description is far too thin — it should at minimum explain theme structure, side effects, and preconditions.

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 theme parameter is a free-form nested object with additionalProperties=true, so its structure is completely undocumented. The description's mention of "render settings" hints that render config lives inside theme, but it provides no keys, formats, or examples to compensate for the total 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?

The description names a verb ("update") and a resource ("project theme and render settings"), but "theme" is never defined and "validated" is ambiguous — it is unclear whether the theme must already be validated, or whether this tool validates it. It does not distinguish this tool from siblings such as project_create or project_build, which could plausibly also touch project configuration.

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 versus alternatives, no prerequisites (does the project need to exist first via project_create?), and no indication of when not to call it. The agent must infer everything from the name.

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