Get Subject Overview

subject_overview
Read-onlyIdempotent

Retrieve a structured listing of all resource categories and topics for a subject, with direct PDF URLs, to understand the full scope of available material.

Instructions

Get a complete overview of all available resources for a specific subject.

Shows all categories (Chapters, Assignments, Question Banks, Previous Year Papers, etc.) and their topics for the given subject. Useful for understanding the full scope of available material before diving into specific topics.

Args:

  • semester (string): Semester number (e.g. "1", "2", "3", "4", "5", "6").

  • subject (string): Subject name exactly as listed in the resource library.

Returns: A detailed listing of all resource categories and topics for the subject, with PDF URLs for each.

Examples:

  • { semester: "4", subject: "Operating System" }

  • { semester: "2", subject: "Maths-2" }

  • { semester: "3", subject: "Database Management Systems" }

Behavior3/5

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

Annotations already declare readOnlyHint, openWorldHint, idempotentHint, destructiveHint. The description adds that it returns PDF URLs and is a read operation, but does not disclose additional behavioral traits beyond what annotations cover.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is concise: a broad purpose sentence, a detail sentence, structured Args/Returns sections, and three examples. No superfluous information; front-loaded with the key verb 'overview'.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a simple overview tool with 2 required parameters and no output schema, the description covers what it returns (categories, topics, PDF URLs) and provides examples. Could mention potential size of results, but overall sufficient.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100% with clear descriptions. The description repeats parameter details and adds examples, which provide extra context but do not significantly extend beyond the schema.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool provides a complete overview of all resources for a subject, listing categories and topics. The verb 'overview' and mention of specific resource types distinguish it from sibling tools like search or get_resource.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description says it's 'useful for understanding the full scope before diving into specific topics,' which implies when to use. It does not explicitly exclude cases or name alternatives, but the context with siblings provides sufficient guidance.

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