origin_ping

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

Annotations are absent, so the description carries the full burden. Where the description explains that the tool 'answers even when originpro is broken', a behavioral trait that is non-obvious from the name and critical for failure-recovery reasoning. The ping semantics also imply a non-destructive read, though the description does not state explicitly that it has a side effects (minor for a 0-param heartbeat tool).

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 sentences, no filler. The core operation is front-loaded in the first sentence, and the second sentence adds a high-value behavioral criterion (works when originpro is broken) that justifies the entire purpose. Nothing earned 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 0-parameter tool with an output schema, the description is largely sufficient: it says what the tool does, what it reports, and when it works. The remaining gap is selection clarity — an agent could hesitate between origin_ping and origin_bridge_status because the description never distinguishes them or routes to one over the other.

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 has zero parameters, so per the rubric the baseline is 4. The description needs no parameter-level detail; the far-end report is the only input/output relevant information, and the tool is invocable with no arguments.

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?

The description gives a specific verb+resource ('Check the bridge is reachable') and states what the tool reports ('report what is on the far end'), making the plumbing immediate. It does not explicitly distinguish itself from the origin_bridge_status sibling, though 'Answers even when originpro is broken' hints at the differentiation without naming it.

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 context is only implied: the line 'which is when it matters most' signals that this tool is valuable during failure scenarios, so an agent can infer it is the right choice when Origin is broken. There is no explicit when-to-use or when-not-to-use guidance relative to origin_bridge_status or the other origin_* tools.

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