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

No annotations are supplied, so the description carries the burden, and it does meaningful work by disclosing that this single config feeds three outputs — the Prep Sheet Settings modal, the Items Purchased page, and the daily Discord DM — warning the agent that changes here have wide blast radius. It never explicitly states that this tool itself is a read-only operation or what the response shape is, which keeps it from 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?

Three sentences, front-loaded with what the tool returns, then the shared-config context, then the call conditions. The 'one config, three outputs' clause is slightly expansive but earns its place by preventing misuse; otherwise there is no redundancy.

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 output schema and no annotations, the description must describe both behavior and returns, and it covers the three config fields an agent needs. It stops short of stating read-only semantics or the exact return format, which is the remaining gap for a config-fetch 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 tool takes zero parameters, so there is nothing for the description to disambiguate and the baseline of 4 applies. The description wisely spends its space on return-content semantics instead of inventing parameter guidance.

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 names a specific resource (the user's prep-sheet settings) and enumerates exactly what is returned: the auto-push flag for new Items Purchased rows, the destination tab, and the column order. It also distinguishes this tool from configure_prep_sheet by name, so an agent can separate read from write without inspecting schemas.

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 two explicit invocation conditions: call before configure_prep_sheet, and call when the user asks how their prep sheet is set up. The alternative (configure_prep_sheet) is named, so the when/when-not split is clear.

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