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

Annotations declare readOnlyHint=false, destructiveHint=false and openWorldHint=true, so safety is already covered. The description usefully explains the template-vs-student branch, but says nothing about what content is duplicated (days, weeks, exercises), whether the copy inherits published state, or permission requirements.

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?

One sentence, no filler, and the branching condition is front-loaded right after the verb. Every clause earns its place.

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?

Adequate for a 3-parameter mutation with no output schema, but incomplete in ways that matter for calling it correctly: what gets copied, whether the copy is draft or published, and default naming behavior are unstated.

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 coverage is already 100%, yet the description adds real meaning: omitting student_id is what produces a template, which the schema's "The student_id from list_students" does not convey. The optional name parameter is left unexplained (e.g. default naming).

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 ("Duplicates") and resource ("a program"), and the same sentence distinguishes the two modes of the operation. An agent can tell this apart from create_program (new program) without opening the schema.

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?

Gives a clear selection rule tied to the input: pass student_id to copy for another student, omit it to create a new template. It stops short of exclusions or prerequisites, e.g. whether the source program must belong to the caller or be published.

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