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

Goes well beyond the annotations by disclosing that an encrypted undo version is saved on replacement, that the tool returns a response envelope whose primary nextAction should be followed, and that preview-then-confirm requires identical inputs. This is meaningful operational context for a destructiveHint=true, non-idempotent mutation.

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 core action and the create-vs-replace default in the first two sentences, then layers the confirmation workflow. Slightly dense and partly duplicative of the schema, but no sentence is wasted.

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?

An output schema exists, so return values need no explanation, yet the description still tells the agent to follow the primary nextAction. Combined with the undo-version and confirmation semantics, an agent has everything needed to call this destructive tool 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 coverage is 100% and the schema descriptions already explain confirm, replace, resumeId and operation in equivalent detail, so the description mostly restates structured data. It reinforces the replace/resumeId coupling but adds no syntax or edge-case detail the schema lacks – baseline 3.

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 and resource ('Import the entire resume text extracted by the chat host') plus the default outcome ('Create a NEW resume by default'). The default-new vs explicit-replace split distinguishes it clearly from siblings like update_item or restore_resume_version.

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?

Gives explicit conditional guidance: provide resumeId, replace: true and confirm: true to replace, and use confirm: false for a preview then repeat identical inputs with confirm: true. It lacks any reference to which sibling tool to pick instead (e.g. restore_resume_version, update_item), so it stops short of naming alternatives.

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