create_discussion_topic

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

No annotations are provided, so the description must disclose behaviors. It only lists parameters; it omits side effects, permission requirements, or what happens after creation (e.g., visibility, notifications).

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 compact: one sentence stating purpose followed by a bullet list of arguments. No unnecessary text, and the key action is front-loaded.

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?

The description covers parameter semantics but lacks behavioral context (e.g., does it require an existing course?). For a 7-parameter tool with no annotations, it is minimally adequate but not fully complete.

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 0%, so descriptions add necessary meaning. Each parameter has a concise explanation (e.g., 'ISO 8601 datetime to schedule posting'). Some descriptions are tautological (e.g., 'Discussion topic title'), but overall they compensate well.

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 'Create a new discussion topic for a course' with a specific verb and resource. It distinguishes from siblings like create_announcement, but does not explicitly differentiate from similar tools, leaving some ambiguity.

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 guidance on when to use this tool versus alternatives (e.g., create_announcement). With many sibling creation tools, the agent needs context on selection criteria.

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