Jev proxy status

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

With no annotations provided, the description carries the behavioral burden. It discloses that this is a read-only status report and specifies the exact six categories of information returned. It does not mention side effects or auth requirements, but 'Report ... status' makes the non-mutating behavior clear.

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?

One front-loaded sentence states the action and resource immediately, then uses a compact colon-separated list to enumerate the reported fields. Every part earns its place and no filler exists.

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-parameter, no-output-schema status tool, the description is complete enough: it names all the categories an agent should expect. Some details like exact value formats of 'Jev usage stats' are left open, but they are not required to invoke the tool correctly.

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 is empty with 100% coverage, so no parameter documentation is needed. Per the baseline for zero-parameter tools, the description cannot add param-level detail, and none is required.

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?

Begins with a specific verb ('Report') and a named resource ('jev-playwright-mcp status'), then enumerates the data it returns: mode, enabled state, session goal, usage stats, budget consumption, and active tool policy. This clearly differentiates it from the sibling browser_* tools, none of which are status-reporting tools.

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 description makes the tool's context clear: it should be used when the agent needs a status readout of the Jev proxy. It does not explicitly name when-not-to-use or alternatives, but there are no sibling status tools to exclude, so the implied usage is sufficient.

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