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

No annotations exist, so the description carries the full burden. It usefully discloses that generation and placement happen SERVER-SIDE and that the value is never surfaced to the conversation — a meaningful behavioral trait. However, it omits auth requirements, whether the secret is retrievable later, idempotency, and error behavior, which for a write-style tool are significant gaps.

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 tight sentence with zero waste, front-loading the core action and the key security property. Nothing redundant or padded.

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 nested-object tool with no output schema and no annotations, the description conveys the central security behavior but leaves too much unstated: how vendor/resource/key identify the destination, what auth is needed, and whether the generated secret can be retrieved afterward. Given the schema's opacity, more was required.

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 largely does not. It references 'a vendor resource' but never explains the vendor/resource/key fields of the nested 'to' object, nor the 'bytes' length parameter (16-64). An agent cannot tell what values these accept or how they map to the placement.

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: generate a random secret and place it at a vendor resource. The scope is clear. It does not explicitly contrast itself with the sibling secret_transfer, so an agent must infer the distinction, keeping it below a 5.

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?

No when-to-use or when-not-to-use guidance. The phrase 'the value never enters this conversation' hints at a security rationale but does not tell the agent when to prefer this over secret_transfer or get_vault_link. No prerequisites or alternatives are named.

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