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

With no annotations, the description carries the load, and it does disclose the key behavioral trait: only the quote-side association is removed while the underlying media persists on the job. It does not say whether the removal is reversible, what happens if attachment_id is unknown, or what permissions are needed.

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?

Two short sentences with no waste; the action is front-loaded and the clarifying consequence follows immediately. Every sentence earns its place.

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 one-parameter mutation with no annotations and no output schema, the description covers the outcome but omits the identifier's meaning and any indication of the response or failure behavior. It is adequate but has clear gaps.

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 0% and the sole parameter attachment_id is never explained in the description. Given the note that the media stays on the job, an agent could reasonably wonder whether attachment_id is the quote-attachment identifier or the media identifier — a genuine ambiguity left unresolved.

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 verb-plus-resource is explicit: it removes a photo or file from a quote, which cleanly contrasts with quotes_addAttachment and quotes_listAttachments among the siblings. It stops short of naming those siblings, but an agent can still tell what the tool does without ambiguity.

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 second sentence ('The media item itself stays on the job') implies when this tool is preferable to outright deleting media, which is useful routing context. However, it never states prerequisites, when-not-to-use conditions, or names the alternative tool explicitly.

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