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

readOnlyHint=true already establishes the safety profile, so the description's burden is lighter. It adds the organizational scoping constraint and the flag-to-application relationship, but says nothing about result size, pagination, or ordering for what could be a multi-item 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?

Two short sentences, no filler, and the core action is front-loaded ahead of the secondary relational note. Nothing could be removed without losing information.

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?

The tool is simple — one required parameter, read-only, and an output schema that covers return values — and the description matches that complexity. The only meaningful gap is that the origin of the organization ID is unexplained.

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?

With one parameter at 0% schema description coverage, the description is the only place semantics appear, and it does indicate the scope is an organization. However, it never names organizationId or explains where the identifier comes from (e.g., list_organizations), leaving the lone parameter only partially compensated.

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 applications in an organization") and adds the relational fact that flags belong to an application, which situates the tool in the resource hierarchy. It does not explicitly distinguish itself from siblings like list_organizations or list_flags, so it falls short of a 5.

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 explicit when-to-use or when-not-to-use guidance. The sentence "Flags belong to an application" implies this is the way to discover application IDs before working with flags, but the agent must infer that routing decision rather than being told it.

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