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

Annotations already declare readOnlyHint=false, destructiveHint=false and openWorldHint=false, so the safety profile is covered by structured data. The description adds that accept routes an item into an optional class, which is useful context beyond the annotations, but leaves the key behavioral question unanswered: whether an accepted or declined item disappears from the inbox and whether decline is reversible.

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?

Two compact clauses, purpose front-loaded ahead of the action parameters, with no filler. Nothing is padded, though the density means the accept/decline rules are packed into a parenthetical that is easy to misread.

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 dual-mode tool with three undocumented parameters and no output schema, the definition should at least say what the listing returns and what state changes after accept/decline. It covers the input side adequately but leaves the agent guessing about results and post-action state.

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 0%, so the description carries the full burden and does explain all three parameters: accept takes an id, decline takes an id, class_id designates the target class and is optional. It stops short of stating what the ids refer to (inbox item ids) or that class_id is only meaningful together with accept and that accept/decline should not be combined.

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?

Names a concrete resource (the colleague inbox) and states both modes of operation: what colleagues sent, what the teacher sent, plus accept/decline actions. The verb+resource pair is specific, though it never distinguishes this tool from the nearest sibling (send_to_colleague, the opposite direction) or clarifies that the read and the mutate modes share one entry point.

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?

'mit accept=id übernehmen ... mit decline=id ablehnen' implies when to pass which parameter, so usage is inferable but never spelled out. There is no explicit statement of when to call it without parameters (to list), no exclusion of alternatives, and no indication of whether accept and decline are mutually exclusive.

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