edubase_post_user_group

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

Annotations indicate readOnlyHint=false, destructiveHint=false, idempotentHint=false, but the description adds no behavioral context beyond 'update'. It does not explain what 'update' entails (e.g., replaces group or appends), required permissions, or side effects, leaving the agent with minimal insight beyond the annotation flags.

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 concise sentence, efficiently front-loading the purpose. It avoids verbosity but still earns its place by stating the tool's action, though it could be slightly more informative.

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?

Given the presence of an output schema and annotations, the description is minimally complete for a simple update operation. However, it lacks context about the nature of 'group' (e.g., code meaning, whether existing group is replaced) and prerequisites, leaving gaps for an agent to fully understand the operation.

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 description coverage is 100%, with brief descriptions for 'user' and 'group' parameters. The tool description itself offers no additional meaning beyond the schema, providing a baseline but no extra value.

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 'Update a user's group' clearly states the verb (update) and resource (user's group), making the tool's purpose evident. However, it does not explicitly differentiate from sibling tools like edubase_patch_user or edubase_get_user_group, leaving some ambiguity about when to use this specific tool.

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 provides no guidance on when to use this tool versus alternatives, nor does it mention prerequisites, exclusions, or context. The single sentence lacks any usage direction, forcing the agent to infer applicability.

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