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

Annotations already declare readOnlyHint=true, idempotentHint=true, and safe behavior, so safety is clear. The description adds useful context about what the skill contains (API usage, code samples, practices), but does not mention output format, size, or any limitations beyond that.

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?

Single sentence, front-loaded with the action and resource, followed by content details. Efficient with no obvious waste, though the parenthetical '(skill)' is slightly redundant with the tool name.

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 read-only retrieval tool with a single fully-documented parameter and no output schema, the description covers what the tool returns at a high level (API usage, code samples, practices). It is complete enough for an agent to call correctly.

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 100%, so the parameter is fully documented in the schema (name, maxLength, examples). The description does not add syntax or format details beyond what the schema provides. Baseline 3 is appropriate given full schema coverage.

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 ('Read one') and resource ('Offline Protocol integration guide (skill)'), and gives examples of the content areas (mesh networking, identity, groups). It doesn't explicitly contrast with siblings like list_skills or search_skills, but the singular 'one' implies retrieval of a full skill by name rather than enumeration.

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?

Implicit guidance from 'one skill' and the required name parameter suggests this is for retrieving a specific skill by name, contrasted with list_skills/search_skills siblings. However, no explicit when-to-use or when-not-to-use guidance is provided.

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