add_custom_skill

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

No annotations are provided, so the description carries full burden. It mentions 'via the UI', hinting at an interaction method, but does not disclose side effects, required permissions, or whether the operation is reversible. For a tool that likely creates a resource, more behavioral details are needed.

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 concise (one sentence) but at the expense of clarity and completeness. It is not well-structured; it lacks logical breakdown and front-loads a confusing phrase. Conciseness without substance is not effective.

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?

Given the tool has 4 parameters (3 required) and no schema descriptions, the description is far too minimal to be complete. Even though an output schema exists, the description fails to provide necessary context for selecting and invoking the 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 0%, meaning the schema has no descriptions for parameters. The description does not explain any of the four parameters (name, description, content, strategy). The agent gets no added meaning beyond parameter names.

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 'Adds a newly created custom skill via the UI', which identifies the resource (custom skill) and action (adds), but the phrase 'newly created' is confusing—it implies the skill was already created elsewhere, contradicting the action of adding. It does not distinguish from sibling tools like 'delete_custom_skill' or 'list_custom_skills'.

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 description provides no guidance on when to use this tool versus alternatives. No context about prerequisites, scenarios, or exclusions is given.

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