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

Annotations already declare readOnly/idempotent/non-destructive/openWorld=false, so the safety profile is covered. The description adds real behavioral context beyond that: the exact shape of the returned page content and the environment constraint 'Works on: Demo shop (sample data)', which tells the agent the data scope is limited.

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 plus a short environment note, with the content scope front-loaded and the usage directive immediately after. No filler or repetition.

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?

An output schema exists, so return values need not be explained (the enumeration is harmless reinforcement), and annotations carry the safety profile. The remaining agent needs — what the call yields, when to reach for it, and the demo-shop data limitation — are all present.

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 100%, so all three parameters (id, account, allowed_values_for) are already documented in the schema, which sets the baseline at 3. The description gestures at attribute values ('which attributes are not filled in') but does not explain what allowed_values_for does or how it changes the response, adding no meaning beyond the schema.

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 verb+resource ('The content of one product page') and enumerates the exact payload: title, description, images, attributes and their values, unfilled attributes, delivery days, and a content-change verdict. It is clearly distinct from mutation siblings like offers_update_content, but it never contrasts itself with the close-named read sibling offers_get, leaving that distinction to the schema.

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 an explicit usage cue: 'Use it before proposing a content change,' which ties it to the offers_update_content workflow. It provides no exclusions or named alternatives (e.g., when offers_get is the better call), so it stops short of a full routing statement.

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