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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and openWorldHint=false, so the safety profile is covered. The description adds only the word 'public' and the breadth of the payload; it says nothing about not-found behavior, payload size, or rate limits beyond what annotations supply.

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 front-loaded sentence with no filler, and the returned content is enumerated up front. The list is long but each item carries selection value by telling the agent what is available without a second call.

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?

With no output schema, the description correctly carries the burden of describing the return payload, and it does so in detail across all the resource's sections. Missing only edge-case behavior (invalid or unknown slug), which is a minor gap for a one-parameter read tool whose annotations already cover safety.

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?

There is a single parameter with 100% schema description coverage, including a slug pattern, min/max length, and a sourcing hint ('from search results'). The description adds no syntax or format detail beyond that, so the schema does the heavy lifting and baseline 3 applies.

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 retrieval of one course's full public profile and enumerates the content domains (eligibility, exams, fees, syllabus, careers, FAQs, specialisations, offering colleges). The scope ('one course', 'full details') implicitly separates it from search_courses, but it never names or distinguishes itself from the close sibling get_college_course_details.

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 explicit when-to-use, prerequisites, or alternative routing. The nearest hint ('Course slug, e.g. from search results') lives in the schema, not the description, and nothing tells the agent when to prefer this over get_college_course_details or search_courses.

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