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

The readOnlyHint/destructiveHint/idempotent annotations already establish the safety profile, and the description reinforces this with 'opens nothing by itself', which is the key behavioral fact an agent needs to avoid double-executing an action. It also explains the routing to browser tools and why direct API access is unavailable. It does not say whether the returned steps are static, curated at a point in time, or how long or structured the output is.

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?

The purpose and the 'returns steps, opens nothing' clause are front-loaded and earn their place. The trailing API note, including 404 evidence dated 11 Nov 2026, is long, undated-relative context that does little to help an agent decide to call this tool and could be trimmed to a short clause.

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 and no output schema, the description carries the burden of telling the agent what comes back, and it does so concretely ('step by step (screens, buttons, fields)'). What is missing is any sense of scope or granularity of the checklist, but for a zero-argument instructional tool this is close to sufficient.

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 no parameter meaning for the description to add and the baseline of 4 applies. The schema correctly declares an empty object with additionalProperties false, and the description does not confuse the agent by implying optional inputs.

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 (inventory checklist) and explicitly says it returns step-by-step instructions with screens, buttons and fields, which tells an agent this is a procedural guide rather than a data query. It distinguishes itself implicitly from inventory data siblings (inventory_report, inventory_value) by promising instructions, though it never names a sibling to contrast with.

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 useful workflow cue: fetch the steps here, then execute them with the cotlet_browser_* tools, and clarifies that this call opens nothing by itself. However, it offers no explicit when-not guidance or comparison against the many adjacent siblings such as ez_lawn_biller_checklist or ez_lawn_biller_service_checklist, so the agent must infer selection from the word 'inventory'.

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