Create A Project Logo

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

Annotations already indicate readOnlyHint=false, so the agent knows it is a write operation. However, the description internally contradicts itself (update vs create) and adds confusion by mentioning 'Portfolio records', which is unrelated to the project logo endpoint. It does not clearly disclose whether the tool creates or updates, nor 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 description is short but contains redundant and conflicting information (update vs create, mention of Portfolio). While concise in word count, the lack of clarity and internal contradictions undermine its effectiveness. Every sentence should add value, but here the first and third sentences contradict each other.

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?

Given the tool has no output schema and three parameters, the description should clearly state what is returned and the outcome. It mentions returning the updated/created object, but the inconsistency (update vs create) leaves ambiguity. There is no description of the response structure, error conditions, or how the upload_uuid must be prepared. The mention of Company Uploads or Project Uploads is helpful but incomplete.

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?

The input schema has 100% description coverage, with clear descriptions for each parameter. The description redundantly lists required parameters (id, upload_uuid) but does not add new semantic meaning beyond what the schema provides. The optional file_name parameter is not mentioned in the 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 is contradictory: it begins with 'Updates the project logo' but later says 'Creates a new Portfolio records' and 'returns the created object'. The title is 'Create A Project Logo', but the first action described is an update. This muddles the tool's core purpose and fails to clearly distinguish it from related tools like 'delete_the_project_logo' or 'update_project'.

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 no guidance on when to use this tool versus other tools for logo or project operations. There is no mention of when not to use it, prerequisites, or comparisons with sibling tools like 'delete_the_project_logo' or 'update_project'.

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