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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false, and the description's "opens nothing by itself" is consistent with that rather than adding new safety information. It does add genuinely useful behavior: the return value is a step-by-step guide with screens, buttons and fields, and that the user's own account/Cloud Browser session is required. The API availability note (XML API, premium plans only, checked 11 Oct 2026) explains the browser path, though it is peripheral to invoking this specific 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?

Short and mostly front-loaded, with the workflow and next-step routing in two dense sentences. The third sentence about Kickserv's XML API availability is secondary context placed last, and the misleading lead verb slightly delays the key fact that nothing is written.

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 tool with no output schema and full annotation coverage, the description covers what the agent needs: that it returns instructions, that it performs no action, and which tools execute the steps. Missing but minor details are the required session state and whether the guide is reusable across tasks.

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 zero parameters, so the baseline is 4 and the description has no parameter meaning to add or omit. It correctly describes a parameterless tool whose output is a guide keyed to a task type.

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 opening sentence says the tool will "Log time entry in the user's own Kickserv account," which reads as a write action, yet the second sentence clarifies it only "Returns how to do it in Kickserv step by step (screens, buttons, fields) and opens nothing by itself." The true purpose (returning a procedural guide) is therefore stated only after a misleading lead, and there is no differentiation from sibling tools like kickserv_create_job that presumably follow the same guide-only pattern.

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?

It gives a clear next step: "then do it with the cotlet_browser_* tools in the user's Kickserv Cloud Browser," which routes the agent to the correct follow-up tools. It stops short of stating when to prefer this guide over other Kickserv entry points or what prerequisites (signed-in account, open browser session) must exist first, so no exclusions or preconditions are given.

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