firenook_status

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

No annotations are provided, so the description carries the full burden. It does disclose the response contents, which is the main behavioral trait for a status call, and a zero-parameter tool has no mutation surface to warn about. However, it says nothing about what happens when nothing is running, whether the call fails or returns an empty listing, or about the cost/latency of probing locators.

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?

It is a single sentence with no filler, but it is a verbless noun-phrase list with an awkward trailing clause ('with no project, the suites whose locators answer') that takes a re-read to parse. Front-loading 'The running Firenook suite' is good; the list structure sacrifices clarity for brevity.

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 explain the return value, and it does attempt that by naming the fields. But several entries are opaque – 'how the project was found' and the fallback clause do not tell an agent what the actual shape or keys of the response will be, which is the main gap for a diagnostic tool.

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 input schema has zero parameters, so there is no parameter semantics to document and the baseline of 4 applies. The description correctly implies there are no inputs to vary, only a mode difference driven by whether a project is configured.

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 enumerates exactly what the tool reports: hub locator, hub status, per-service emulator host/port, and CLI version. That is specific enough to separate it from every sibling (all of which operate on a single resource such as firestore_get or emulators_clear). It stops short of a 5 because there is no verb – the reader must infer 'reports/returns' from the noun phrase 'The running Firenook suite'.

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: the field list suggests calling it to discover the hub and emulator endpoints before invoking other tools, and the trailing clause hints at a fallback discovery mode when no project is set. There is no explicit when-to-use, no when-not-to-use, and no named alternative among the 50+ siblings.

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