getSkillGuide

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

No annotations are present, so the description carries the behavioral burden. 'Return the guide' clearly signals a read-only retrieval operation with no side effects, and the description names the exact artifact (skill.md) being returned. It does not mention authentication or output format, but for a zero-parameter documentation retrieval tool this is a minor gap.

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 a single, front-loaded sentence that names the action, the artifact, and the guide's scope without any unnecessary words. The parenthetical explanation is compact and informative.

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 zero-parameter tool with no output schema, the description fully equips an agent to invoke it: it names the artifact, clarifies that it returns the onboarding guide, and previews the guide's contents. Nothing essential is missing for correct invocation.

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 tool has zero parameters, and the schema already fully documents this with 100% coverage, so no parameter-specific guidance is required. The description adds value beyond the empty schema by outlining what the returned guide covers, including the journey from sign-up to webhooks.

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 ('Return') with a specific resource ('CallRemind MCP onboarding guide (skill.md)') and enumerates the guide's coverage: signing up, quick calls, scheduling, agents, and webhooks. This clearly distinguishes it from the sibling tools, which perform operational actions rather than retrieving documentation.

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?

The 'onboarding guide' framing makes the intended usage clear: call this tool when the agent or user needs the step-by-step product journey from sign-up through scheduling, agents, and webhooks. It does not explicitly mention alternatives or exclusions, but no sibling tool serves this documentation-retrieval role, so the context is sufficient.

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