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

Annotations already declare readOnly, idempotent, non-destructive behavior, so the safety profile is covered. The description adds genuinely useful context beyond that: secrets are entered directly on the settings page and this tool accepts no keys or passwords, which steers the agent away from trying to supply credentials.

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?

Two sentences, front-loaded with what the tool returns, followed by the secrets constraint. Slightly prose-heavy in the first sentence but no wasted clauses.

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 single-parameter, read-only link generator with no output schema, the description covers purpose, target audience, and the critical secret-handling constraint. Only minor gaps remain, such as link lifetime or authentication requirements.

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 enum is self-describing, so the baseline is 3. The description loosely illustrates what several pages are for (API keys, Slack/GitHub, billing, security) but does not map enum values like get-started, assistants, domains, or repositories, so it adds only marginal meaning.

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?

Names a concrete resource (a link) and its purpose: letting the person complete a setup step themselves. It implicitly distinguishes itself from the many get_*_settings readers by emphasizing the human-completion angle, though it never names an alternative explicitly.

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 rather than stated: the agent can infer it should call this when a task must be finished by the user (pasting keys, approving Slack/GitHub). There is no explicit when-to-use/when-not framing or reference to competing tools such as get_ai_settings or get_billing_status.

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