Delete The Project Logo

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

The description adds significant behavioral context beyond the annotations: 'Permanently removes the project logo. This cannot be undone, and a repeat call returns 404.' It also details common error scenarios (401, 403, 404) and their causes, which helps agents anticipate failure modes. This is excellent value beyond the destructiveHint and idempotentHint flags.

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 information-dense with useful content, but there is minor redundancy: 'Confirm the target id with the matching show or list tool before calling' and 'id must identify an existing parent record — resolve it with the matching list tool first' repeat the same instruction. Still, every sentence contributes to safe usage.

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 simple delete operation with one parameter, the description covers prerequisites, behavior, irreversibility, repeat call outcome, and error codes. It doesn't state the success response (e.g., 204 No Content), but given there's no output schema and the operation is straightforward, this is a minor 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?

Although the schema already covers 100% of parameters, the description adds crucial semantics: 'id must identify an existing parent record — resolve it with the matching list tool first.' This tells the agent how to obtain a valid id, which is not evident from the schema's simple 'unique identifier for the project' description.

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 clearly states the tool's function: 'Updates the project setting the logo reference to null' and 'Permanently removes the project logo.' This specific verb+resource combination distinguishes it from related tools like create_a_project_logo and update_companys_logo.

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?

Provides explicit preconditions: 'Confirm the target id with the matching show or list tool before calling' and 'id must identify an existing parent record — resolve it with the matching list tool first.' It also notes the tool requires the id parameter. However, it doesn't explicitly compare to alternatives like delete_company_logo, so there's no clear when-not-to-use guidance.

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