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

With annotations already declaring readOnly=false, destructive=false, idempotent=false, and openWorld=false, the description adds useful behavioral constraints: it uses store-editor validation, forbids inventing prices/stock/safety claims/policies, and requires confirmed flags only for seller-confirmed facts. It does not explain version-conflict or validation-error behavior, but it adds substantive context beyond the annotations.

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 purpose, then guardrails, then the publishing limitation. Every sentence carries relevant behavioral guidance with no repetition or wasted framing.

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?

This is a complex mutation with a nested catalog, three required parameters, and no output schema, yet the description focuses almost entirely on behavioral guardrails. It mentions edit_url in passing but leaves the agent without parameter semantics or validation details needed to call it correctly.

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 0%, and the description does not explain store_id, version, or the nested catalog object. "Confirmed flags" hints at catalog contents, but there is no mapping to the required parameters or explanation of why version is required.

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 and resource: "Save reviewed draft changes" and ties it to the store editor's validation. It implicitly distinguishes saving an existing draft from creating or fetching one, but it does not explicitly name siblings like create_store_draft or get_store_draft.

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 clear usage context for reviewed draft changes, plus boundary conditions: "No publishing or payment activation; open the edit_url for explicit seller confirmation." It does not explicitly route the agent to create_store_draft when no draft exists, but the save-oriented guidance is clear.

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