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

The annotation set (readOnlyHint=true, destructiveHint=false) is consistent with the description's explicit claim that the tool 'opens nothing by itself' and only returns instructions, so an agent will not expect a write side effect. It adds real context beyond the annotations: the two-stage workflow requiring browser tools, and the note about API plan limits explaining why browser automation is needed. It does not describe the shape or granularity of the returned instructions, so it is not a 5.

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?

Purpose and the 'opens nothing by itself' caveat are front-loaded, which is the right ordering. The closing sentence about Sprout Social's REST API plan requirements is slightly tangential but earns its place by justifying the browser-based workflow. Minor redundancy between 'opens nothing by itself' and the browser-tool instruction keeps it from a 5.

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?

With no parameters, no output schema, and annotations already covering the safety profile, the description supplies what an agent needs: what it returns, that it is inert, and which tool family completes the task. Gaps are minor, such as what to do if the returned procedure fails or how much detail to expect.

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 and the description does not need to explain any inputs. There is a minor implicit expectation that the post content/account context comes from the conversation, but with 0 params the baseline of 4 applies.

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 states a specific resource and outcome: it returns step-by-step instructions for scheduling a post in the user's own Sprout Social account (screens, buttons, fields). It notably clarifies that, despite the name, the tool does not perform the scheduling itself, which prevents a wrong mental model. It does not explicitly differentiate itself from the other sprout_social_* siblings, which keeps it at a 4.

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 concrete next-step guidance: call this to get the procedure, then execute it with the cotlet_browser_* tools in the Sprout Social Cloud Browser. That is a clear when-to-use and how-to-continue instruction. It does not name any when-not-to-use case or an alternative sibling (e.g. listing queued posts instead of scheduling), so it falls short of a 5.

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