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

Annotations already declare this a safe, read-only, closed-world call, so the safety burden is covered. The description adds genuinely non-obvious behavioral context: identity is derived from the visitor pass, guests are matched via conversation label, and cross-device invisibility is expected rather than a bug — this preempts a false-negative interpretation by the agent.

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 sentences, front-loaded with what is listed and for whom; the second sentence earns its place by heading off a misread of empty results. Slightly dense em-dash construction, but no filler.

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?

With no parameters and no output schema, the description carries only the identity/scoping burden, which it discharges well. It says nothing about result ordering, volume, or pagination, but for a zero-argument self-scoped list that is a minor gap.

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 tool takes zero parameters, so the baseline is 4. There is nothing in the schema or description to clarify, and the description correctly spends its words on identity semantics instead of parameter detail.

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?

States a specific verb and resource ('List the feedback tickets') plus a clear scope ('of the current visitor', 'for the Workspace tab'), which separates it from ticket-scoped siblings like get_feedback_thread. It does not explicitly name an alternative tool, but the scoping does the differentiation work.

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?

Usage is implied rather than stated: the agent is expected to infer 'use this to see your own feedback'. The description does usefully explain when results will be empty (guest on another device), but it names no alternative tool for reading others' or threaded feedback.

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