get_skill_gaps

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

No annotations are provided, so the description carries the full burden. It discloses the output categories and states that recommendations are returned, adding some behavioral context. However, it does not explicitly confirm read-only behavior, permissions, or side effects, though 'Get' strongly implies a safe read. It partially covers what an agent should expect.

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 and front-loaded with the core purpose, followed by a compact Args/Returns structure. It avoids unnecessary filler. The phrase 'identified for a student' is slightly redundant with the tool name, but overall every sentence adds useful information.

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 low-complexity tool with one parameter and an output schema, the description covers the primary usage, the parameter format, and the return content. It lacks explicit usage guidelines and prerequisites (e.g., student must exist), but given the output schema exists, the description is reasonably complete for correct invocation.

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%, and the description compensates by adding that student_id is a UUID, clarifying the expected format beyond the schema's generic string type. It does not provide additional details like formats or validation rules, but for a single simple parameter this is adequate. It improves on the schema but does not fully enrich it.

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?

Clear verb+resource: 'Get skill gaps identified for a student.' The description further specifies the three gap categories (missing, weakly evidenced, declared-but-unverified), which distinguishes it from sibling tools like get_skill_evidence that focus on evidence rather than gap analysis.

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?

Usage is implied: invoke for a student to receive a skill gap analysis. No explicit comparison to sibling tools (e.g., get_skill_evidence, get_profile_completeness) nor any when-not-to-use guidance. It is not misleading, just missing explicit alternatives.

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