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

Annotations already declare destructiveHint=true, readOnlyHint=false, idempotentHint=false and openWorldHint=true, so the safety profile is largely covered. The description still adds value the annotations cannot per-call: any dispatched operation is a write, and deletion only happens on explicit request. It omits failure behavior for an unknown or read-only toolName, which is the main remaining gap.

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, no filler, with the core action front-loaded and the acceptance constraint immediately after. Every clause carries information an agent needs to use the dispatcher correctly.

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 generic dispatcher over an open-ended catalog, the description covers the write-only restriction and the arguments pass-through, which are the essentials. It is missing the discovery step that makes toolName resolvable and any note about what happens when the named operation is unknown or read-only -- meaningful omissions given there is no output schema to fall back on.

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 0%, so the description must carry the load, and it does explain the key semantic: toolName names an entry in the catalog and arguments is a pass-through blob whose shape is defined by that cataloged operation, not by this schema. What it does not say is where to look up valid toolName values, leaving the most important parameter only partly grounded.

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: run one cataloged MagicInterview write operation, passing its schema-defined arguments. This distinguishes it from the read-side siblings (magicinterview_read_tool, magicinterview_app_read) by restricting it to write operations. It stops short of naming the discovery tool that supplies toolName, so the routing picture isn't fully closed.

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?

Gives one hard usage condition -- only operations annotated readOnlyHint: false are accepted, and deletions must be explicitly requested -- which is genuinely actionable. However it never states the prerequisite workflow (call magicinterview_get_tool_catalog or learn_tools first to obtain a valid toolName) nor explains when to use the direct sibling magicinterview_app_write instead.

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