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

Annotations already declare readOnlyHint=true and openWorldHint=false, so safety is covered; the description adds genuinely new behavioral context about anonymity (a name appears only if a child volunteered it) and an explicit constraint not to deanonymize entries. It still says nothing about ordering, defaults or volume of returned data.

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?

Three compact sentences with zero filler: what is returned, how to filter, then the usage warning. Front-loading the returned fields before the filter mechanics is the right order.

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?

No output schema exists, and the description compensates by listing the entry fields an agent will receive. Combined with annotations covering the read-only profile, the only real gaps are default status and result ordering/pagination.

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 67% with days and class documented in the schema; the description restates the three filters and spells out status values. That adds marginal value, but it lists only new/read/archived while the enum also allows 'all', and the default status when omitted is unexplained.

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 specific verb (lesen/list) and resource (anonyme Einträge der Wunschboxen) and even enumerates the returned fields (Kategorie, Text, Stimmung, Tag, Name). It does not name a sibling such as mark_feedback_read, so the differentiation is only implicit.

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?

States that filtering is optional and that the tool is 'Zum Zusammenfassen gedacht', which gives real usage intent, plus a clear prohibition (never attribute entries to children). However it never says when to pick this over mark_feedback_read or list_parent_items, so the when-to-use guidance remains implied.

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