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

Annotations already declare readOnlyHint=false, idempotentHint=false, destructiveHint=false, so the safety profile is partly covered. The description adds the useful auth constraint ('Admins only') and tells the agent what to do with the result, but omits link lifetime, whether repeated calls invalidate prior links, and what non-admins get — meaningful gaps for a non-idempotent, non-read-only call.

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?

Three short sentences, front-loaded with the purpose, then the action to take, then the constraint. No filler; each sentence carries distinct information.

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?

There is no output schema, and the description only loosely implies the return value is a URL. Missing pieces an agent would want for a non-read-only link-generation tool: link expiry/one-time semantics, behavior when already connected, and any meaning for the two undocumented parameters.

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% and the description says nothing about either parameter. 'request_id' and 'idempotency_key' are opaque: the agent cannot tell whether request_id is a correlation handle or required for retry, nor what scoping the idempotency key applies to. With both undocumented, the description fails to compensate for the schema gap.

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 ('Get the Slack consent link'), which is clearly distinct from the other Slack siblings (disconnect, status, me, member_set). It does not explicitly say how it relates to slack_status (checking whether a connection already exists), so it falls just short of full sibling differentiation.

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?

'Open it in a browser to connect' implies the workflow, and 'Admins only' gives a prerequisite. But there is no guidance on when to call it versus yardstick_slack_status or slack_me, nor on whether to call it if a connection already exists — usage is implied rather than stated.

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