get_front_page

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

The readOnlyHint annotation already communicates the safe read-only nature. The description adds no extra behavioral context, such as permission requirements, return format, or any side effects. It is consistent with the annotation but adds minimal value beyond it.

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 a single sentence, front-loaded with the verb 'Get', and contains no redundant or filler words. Every word earns its place, making it an ideal concise description for a simple getter.

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 one-parameter, read-only tool with no output schema, the description is adequate but not thorough. It doesn't clarify what 'content' includes (e.g., HTML, text, metadata) or elaborate on how the front page is determined, which could lead to slight ambiguity for an agent.

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?

The schema already provides 100% coverage with a clear description of 'course_identifier' (Course code or Canvas ID). The tool description itself adds no parameter-level detail, so the baseline of 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?

The description clearly states a specific verb ('Get') and resource ('front page content') with a clear scope ('for a course'). It distinguishes itself from sibling tools like 'get_page_content' by targeting the course's front page specifically, making the purpose unmistakable.

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 implies usage (retrieve front page content) but provides no explicit guidance on when to use this tool versus alternatives like 'get_page_content' or 'get_course_details'. No mention of exclusions, prerequisites, or conditions.

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