token_bowl_chat_update_my_logo

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

No annotations exist, so the description carries the full burden: it identifies this as a self-mutation, explains that passing None clears the logo, names the return payload, and documents the ValidationError on invalid input. Minor gaps remain (auth requirement, rate limits), but the mutation semantics and failure mode are disclosed.

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?

Front-loads the action and usage, then the Args/Returns/Raises blocks. Slightly verbose given the return schema already exists, but every line earns its place against zero schema coverage.

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 single-parameter mutation with no annotations, it covers purpose, valid-value source, removal path, return shape, and error. Only supporting details like auth scope and side-effect timing are absent.

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%, so the description must compensate, and it does: it defines logo_name as a valid filename sourced from get_available_logos() and documents the special None value that clears the logo. This is meaningfully more than the bare anyOf[object/null] 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?

States a specific verb pair (set/remove) and resource (Token Bowl Chat profile logo), scope clear as the caller's own profile. Easily distinguished from siblings like token_bowl_chat_update_my_username and update_my_webhook.

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?

Explicitly routes to the sibling get_available_logos() for valid choices and states the None branch for removal. The when-to-use (customize profile) and the two operational paths are both covered with no inference required.

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