Poisar Public

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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false, and openWorldHint=false, so safety behavior is fully covered by structured data. The description adds only the notion that the links are 'canonical public' (authoritative, non-user-specific), which is modest extra context but nothing about return format or caching.

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 with no filler; the resource type and its scope are stated immediately. Every word earns its place.

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 zero-param, read-only tool with rich annotations, the definition is mostly adequate, but with no output schema it leaves the agent guessing what the links actually point to or how many are returned. A brief note on the returned link set would close the gap.

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 no parameters, so the baseline is 4 per the rubric. The description correctly implies a parameterless call, and there are no parameters whose meaning could be misread.

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 ('Return') and resource ('canonical public agent-readiness discovery links'), which is clear enough to distinguish it from get_public_overview at a high level. It stops short of explicitly contrasting with the sibling, so it is not 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?

The word 'discovery' hints at a use case, but there is no explicit when-to-use guidance, no prerequisites, and no mention of the alternative get_public_overview. The agent must infer the routing on its own.

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

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

Annotations already cover the safety profile (readOnlyHint, idempotent, non-destructive, non-open-world), so the bar is lower. The description adds that the response includes discovery links and protected-route boundaries, which hints at content. But it says nothing about auth requirements despite the 'protected-route boundaries' framing, and nothing beyond what the annotations imply about behavior.

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 listing the returned content with zero filler. Appropriate for a parameterless read tool.

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?

There is no output schema, so the description must convey what comes back — and it does list three content categories. However, for a tool whose whole value is knowing what's in the overview versus the sibling readiness-links tool, it stops short of meaningfully distinguishing them.

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?

Zero parameters, so the baseline of 4 applies. The description correctly implies a no-argument call, consistent with the empty schema.

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 (Return) and resource (public overview, discovery links, protected-route boundaries) for a named target (Poisar). It distinguishes content but does not explicitly differentiate from the sibling get_agent_readiness_links, which also sounds like a discovery/links endpoint — an agent could confuse the two.

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?

No when-to-use guidance, no when-not-to-use, and the sibling get_agent_readiness_links is never mentioned. The agent must guess which of the two link/overview tools to call.

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