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

No annotations are supplied, so the description carries the full burden. It usefully discloses 'No auth required,' but says nothing about whether the call is read-only, whether the returned guide is static or state-dependent, or how large the response is. The keyword 'loop' hints at iteration behavior without explaining it.

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 with no filler, and the role list is front-loaded. The brevity is appropriate in form, though it reflects under-specification rather than disciplined compression.

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 and no annotations, the description should explain the return value and the per-role behavior, but it does neither. An agent knows only the four role strings and that no auth is needed — not enough to invoke this confidently over siblings.

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 single required role parameter has an enum but 0% schema description coverage, and the description only echoes the enum values back. It adds no meaning about what each role implies, how the returned guide differs per role, or whether role selection has side effects.

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?

"Short role loop" is an unclear abstraction that mostly restates the tool name; 'loop' is never defined, so the agent cannot tell whether it returns instructions, a checklist, or a sequence of steps. It names the four role values but does not say what the tool actually produces for a given role.

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 statement of when to call this versus siblings such as get_next_actions, install_guide, or get_eligibility. The only implied usage is picking a role, with no conditions, ordering, or exclusions provided.

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