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

Annotations already declare readOnly, idempotent, non-destructive, and closed-world, so the safety profile is covered. The description adds topical scope (it explicitly says the tool runs beside an ERP and EDI provider and covers data handling), but says nothing about whether the content is static, versioned, or how the output is organized.

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?

A single sentence, front-loaded with the primary topic ('what Samplyn connects to') and with the parenthetical adding useful scoping detail rather than filler. The trailing list of extra topics is slightly loose but each item earns its place.

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?

An output schema exists, so return values need no explanation, and a zero-parameter, read-only documentation tool is a simple surface. Given that, the description is nearly complete — the only missing element is a hint about which sibling to prefer.

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 takes zero parameters, so there is nothing for the description to disambiguate and the baseline applies. No parameter-level claims are made or needed.

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 enumerates content areas (integrations, limits, roadmap gaps, data handling) rather than stating a clear verb+resource action, and it never names a sibling it differs from. An agent can infer it returns documentation about integrations, but the mixed scope of four topics makes the purpose vaguer than a clean 'list supported integrations' statement.

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 at all — nothing says to call this instead of get_capabilities, get_faq, or compare_with, nor any condition that selects it. The agent must guess from sibling names alone, which is exactly what the guidance should have prevented.

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