Replace a technician's skills

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

The description fully discloses the behavioral traits beyond the minimal annotations. It explains the replace semantics (removing/adding), constraints that all skills must be active and belong to the business, and specific error responses (SKILL_NOT_FOUND with missing_ids, SKILL_INACTIVE with inactive_ids). No contradictions with annotations.

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 with only two sentences in the second paragraph, but the first line is a header-like repetition. The structure is clear with a brevity introduction followed by detailed behavioral notes. Minor verbosity is acceptable, but could be slightly tighter.

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's low complexity (2 parameters, no output schema), the description covers all essential aspects: operation semantics, parameter constraints, error conditions, and clearing behavior. It is fully self-contained and requires no additional information for correct usage.

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?

With 100% schema description coverage, the baseline is 3, but the description adds significant value beyond the schema. It explains the replace semantics apply to both parameters, clarifies that skill_ids must be active and belong to the business, and details the error response structures. The example and maxItems in schema are complemented by practical usage guidance.

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 name and title clearly indicate the action: replacing a technician's skills. The description explicitly states 'replace semantics' and details that skills not in the list are removed and new ones added, distinguishing it from sibling tools like listSkillsByCategory or replaceTechnicianBuddies, which target different resources.

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 explains the replace semantics and mentions passing an empty list to clear all skills, providing clear context for usage. However, it does not explicitly state when not to use this tool or suggest alternatives, which is a minor gap. The context from sibling tool names partially compensates.

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