Preview (HTML page)

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

Annotations already declare readOnlyHint=true and openWorldHint=true, so the safety profile is covered. The description adds nothing beyond restating 'GET' — it does not say whether the token is public/unauthenticated, whether the response is raw HTML meant for rendering, or whether access can fail on expired links.

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?

It is one short, front-loaded line with no filler, but the brevity stems from under-specification rather than discipline; the path fragment is the only substantive content.

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 tool is simple (one path parameter, no output schema) and the annotations cover read-only semantics, yet the description still leaves the agent without the token's origin or the fact that the return value is a renderable HTML document rather than JSON.

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% for the single required parameter. The only hint is the '{token}' placeholder in the path, which implies it is the approval-link token, but there is no explanation of where that token comes from or what makes it valid.

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 gives a verb ('Preview') and, via the HTTP route GET /v1/approval-links/{token}, identifies the resource as an approval link. However, it is essentially the title restated plus a path, and it does not distinguish this tool from siblings such as approvalLinks_decide, publicReports_html, or invites_preview.

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?

There is no when-to-use guidance, no mention of prerequisites, and no named alternative. An agent cannot tell from this text when to call preview versus approvalLinks_decide or approvalLinks_slackInteraction.

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