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

Annotations already declare readOnlyHint, idempotentHint and destructiveHint=false, so the safety profile is covered structurally. The description adds only 'with its full text' (returns the complete body, not a summary) while 'Read-only' merely restates the annotation. No pagination or size caveats are given.

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 short fragments, front-loaded with the core action and no filler. It is terse rather than padded, though the trailing 'Read-only' clause earns little given the annotation already says it.

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 simple read with no output schema, the description hints at the return ('full text') but omits anything about the path scoping, workspace binding, or size/truncation behavior. Adequate at minimum viable level, but not complete for a 3-parameter tool.

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 only 33%, and the description explains only the id parameter implicitly. It says nothing about what 'path' (default '/') scopes or how workspace_id binds, so it fails to compensate for the undocumented parameters.

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+resource ('Read one skill by id') and adds scope ('full text'), so it is distinguishable from the read_memory and read_rule siblings by resource noun. It does not explicitly contrast itself with those siblings, but the resource naming carries most of the 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?

No when-to-use guidance, no prerequisites, and no mention of alternatives such as list_skills or history_skill. The agent is left to infer that this is the single-item retrieval path when an id is known.

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