Add a skill

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

The description discloses that the tool mutates the profile by adding a skill and reveals an additional behavioral trait: it 'returns the verified skills state.' However, with no annotations and no further context, the meaning of 'verified' and any side effects are left unclear.

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 efficient sentence that front-loads the action and adds a useful behavioral note about the return value. No filler or redundancy.

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 one-parameter tool, the description covers the core action and return behavior. But it lacks usage context, explanation of the verification state, and any behavioral caveats, which matters because no annotations or output schema exist to fill those gaps.

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 schema has 0% description coverage and the single 'name' parameter is undocumented. The description indirectly implies that 'name' is the skill to add, but says nothing about format, constraints, uniqueness, or accepted values.

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 clearly states the action ('Adds a skill') and the target resource ('the profile'), making the purpose obvious. It is clear enough to be distinguished from siblings like remove_skill or reorder_skills, though it does not explicitly name any alternative.

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 usage guidance is provided. There is no indication of when to prefer add_skill over endorse_skill or update_profile, no prerequisites, and no exclusion cases.

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