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

The annotations already flag destructiveHint=true, and the description adds meaningful risk context: recipient identity is what makes a link dangerous and readers are told their section reads are visible. It still omits details about link expiry, revocability, and permission requirements, but it adds valuable behavioral context beyond the annotations.

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?

The description is short and front-loads the core action and recipient scope. The final rationale about danger and naming is purposeful, though slightly verbose for a three-sentence definition.

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?

The output schema exists, so return values need not be described, and the destructive nature is partially addressed through recipient confirmation. Still, for a six-parameter destructive sharing tool with low schema coverage, missing guidance on expiry, required company context, and relationship scoping leaves 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?

The description adds meaning for recipient/firm selection and confirmRecipient by saying to name the recipient address exactly. However, with only 33% schema description coverage, it leaves several parameters such as companyId, relationshipId, and expiresInDays unexplained, so compensation is only partial.

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 description states a specific verb and resource: "Issue one memo link" for either one investor or a firm-level code. It is clear what the tool does, though it does not explicitly distinguish itself from sibling tools such as revoke_memo_link or get_list_memo_links.

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?

Usage is implied by the phrase "Issue one memo link for one investor, or a firm-level code," but no explicit when-to-use or when-not-to-use guidance is given. The confirmation instruction is procedural rather than guidance about choosing this tool over alternatives.

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