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

Annotations already declare destructiveHint=true and readOnlyHint=false, so the agent knows this mutates/destroys state. The description usefully adds that it targets a single (one) failed generation and involves reconciliation, but says nothing about what specifically is torn down or how the idempotency_key governs retries.

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?

A single front-loaded sentence with no filler, so it is appropriately terse. The terseness borders on under-specification rather than being a structural flaw.

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 destructive tool with 5 undocumented parameters, no usage routing, and an output schema already covering returns, the description leaves major gaps. An agent lacks prerequisites and parameter guidance needed to invoke it safely.

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% across 5 parameters, so the description carries the full burden and provides none of it. Terms like file_hash, idempotency_key, upload_attempt, folder_name, and connection_context are left entirely unexplained.

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 (abandon) and resource (a failed creative upload generation), with 'reconcile' clarifying it cleans up state. It scopes itself to failed uploads, which implicitly separates it from creatives_confirm_upload and creatives_request_upload, though it never names those siblings.

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 word 'failed' implies the trigger condition, but there is no explicit when-to-use, when-not, or reference to the sibling confirm/request upload tools that represent the alternate paths. The agent must infer the workflow position.

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