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

With no annotations, the description carries the full burden; it does disclose two real behaviors an agent needs: the call blocks and polls, and progress goes to stderr/MCP logging. It omits timeout behavior, failure handling, default wait/poll values, and whether partial deploys are left behind — significant gaps for a long-running provisioning operation.

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, verb-first, zero padding; the core action and its blocking nature are front-loaded. The logging sentence is secondary but still informative rather than filler.

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?

It does tell the agent what the call yields (deployed environment plus component URLs), which is useful given there is no output schema. But with no annotations and no parameter documentation, the definition is thin on timeout semantics, defaults, and error behavior for an operation that can block for minutes.

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?

Schema description coverage is 0% and all three parameters (branchName, maxWaitMinutes, pollIntervalSeconds) are bare types. The description gestures at polling but never explains the wait/poll knobs, their defaults, or what branchName selects, so the schema gap is not compensated.

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 ('Provision'), the target resource ('BunnyShell ephemeral environment'), and adds the blocking behavior ('poll until deployed'). This is clearer than most, but it never contrasts itself with the sibling 'provision-ephemeral-environment', which the '-and-wait' suffix implicitly duplicates.

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 polling/waiting behavior implies the usage context (you need the environment ready before the next step), but there is no explicit when-to-use statement, no mention of the non-waiting sibling as an alternative, and no guidance on combining it with 'get-ephemeral-environment-status' or 'destroy-ephemeral-environment'.

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