sysknife_list_toolboxes

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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false and openWorldHint=false; the description's "Read-only SysKnife action" merely restates that, earning no credit. Beyond the safety profile nothing is disclosed — no return shape, no scoping to the invoking user vs. all users, and no note that an empty toolbox set is a normal result.

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?

Very short and front-loaded, which is good, but the leading sentence "Read-only SysKnife action `ListToolboxes`" spends roughly half the text repeating the tool name and the readOnlyHint already in structured data. The genuinely useful clause is only the trailing fragment.

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 simple read-only list operation with no output schema and rich annotations, the description covers the essential act and its scope (toolboxes for a given user). Incompleteness is limited to the unresolved username/schema mismatch, which is a parameter issue rather than a missing behavioral concern.

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 input schema declares no properties (0 parameters, additionalProperties: true), yet the description asserts a required "username*" argument. That is the only parameter semantics available, but it directly conflicts with the structured schema, so an agent reading the schema would call with an empty object while the description implies the call will fail without a username.

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+resource pair ("list toolbox containers for a user"), which is more informative than the name alone and distinguishes it from generic container tools. It does not, however, contrast itself with near-siblings such as sysknife_list_containers, sysknife_distrobox_list or sysknife_multipass_list, so an agent must infer that "toolbox" means the Toolbx/fedora-toolbox subsystem.

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?

There is no when-to-use guidance, no exclusions and no mention of alternatives. The only routing signal is the word "toolbox", and the neighboring list_containers/distrobox/multipass tools are never referenced, so an agent has no stated rule for choosing among them.

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