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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and openWorldHint=false, so the safety profile is fully covered. The description adds the meaningful detail that the content is 'public,' implying no authorization is needed, but says nothing about whether the data is static or live, and the output schema already documents return shape.

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 front-loaded sentence that lists the three returned content areas with no filler. Every phrase maps to a distinct part of the payload.

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 zero parameters, complete annotations, and an output schema documenting the return values, the description need only say what domain of information it covers — which it does. The phrase 'central protocol issue-directory details' stays somewhat opaque, leaving a small gap an agent must resolve at call time.

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 tool takes zero parameters, so the baseline is 4 and there is no parameter semantics to clarify. The description correctly implies a parameterless fetch rather than suggesting any input is expected.

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?

Uses a specific verb ('Return') and enumerates the exact content domains: support workflow, privacy limits, and issue-directory details. The resource is clearly identified as a public informational payload for Poisar, though it never distinguishes itself from siblings like poisar_get_public_overview.

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?

Usage is only implied by the content names — an agent can infer 'call this when you need support or privacy info.' There is no explicit when-to-use statement, no mention of when the sibling overview or readiness-links tools would be the better choice.

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