Create A Project Logo

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

Annotations already indicate a non-readonly, non-idempotent operation. The description adds valuable context: calling it again creates another record, failures return error payloads with HTTP statuses (401, 403, 404), and `id` must reference an existing parent. This goes beyond what annotations convey, despite the internal update/create wording confusion.

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 description is dense with useful information (endpoint, errors, required params), but it contains a contradictory first sentence ('Updates' vs 'Creates') and a typo ('from a upload'). These issues make it less concise and structured than it could be.

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 tool with no output schema, the description covers return values ('updated project', 'new id'), error conditions, required parameters, and the API endpoint. However, the ambiguity about whether it updates an existing logo or creates a new one leaves the agent unsure of the exact side effect, so it is not fully complete.

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 coverage is 100%, so the baseline is 3. The description adds meaning by explaining that fields should be passed as top-level arguments despite being nested under 'logo' in the payload, and it clarifies that `id` is a parent project identifier and `upload_uuid` references a prior upload. This is useful beyond the schema.

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 opens with 'Updates the project logo' but later explicitly states 'Creates the project logo and returns it with its new id (HTTP 201); calling it again creates another record,' creating an internal contradiction over whether this is an update or create. The tool name and endpoint clarify it is a create operation, but the first sentence is misleading.

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?

The description provides usage context by telling the agent to resolve `id` with a list tool first and listing required parameters (`id`, `upload_uuid`). However, it does not explicitly state when to use this tool over sibling tools (e.g., `delete_the_project_logo`) or when not to use it, so guidance is implied rather than explicit.

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