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

Annotations already establish readOnlyHint=true and openWorldHint=false, so safety is covered. The description adds that one of the outputs is a message intended for forwarding to the client, which is useful framing, but says nothing about failure modes, whether a badge is guaranteed, or response shape beyond the field list.

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?

A single dense sentence with the resource identified first, outputs second, and the platform behavior last. No redundant restatement of the title or 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 output schema, the description carries the return-value burden and does so by naming the three payload pieces. Slightly incomplete in that it does not say what 'status' values look like or what happens when no badge exists yet.

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 100%, so both parameters are already documented, including the platform field's meaning. The description reinforces the optionality of platform and its narrowing effect on the result, but adds no format or valid-value detail beyond what the schema states.

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 the concrete resource (the agency-branded badge some directories require) and enumerates what comes back: status, a client-facing message, and install code. An agent can tell it apart from verify_badge or find_directories without opening a schema, though neither sibling is named.

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?

"Call without platform to see the platforms" is a genuine operational instruction that tells the agent how to discover valid values before a targeted call. No explicit exclusions versus verify_badge or project_directories, so it stops short of a 5.

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