activate_store

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

Annotations supply openWorldHint and idempotentHint (retry safety), and the description adds genuinely new behavioral context: the hard prerequisite of a connected fulfillment provider and the failure it causes if unmet. It stops short of covering auth/permission requirements or what the response returns.

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 tight sentences, front-loaded with the purpose and then the prerequisite and sequencing. The stray '[#87c31f]' artifact is noise that slightly detracts from an otherwise efficient description.

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?

For a two-parameter state-mutation tool with no output schema and annotations covering the safety profile, the description covers purpose, prerequisite, failure mode, and sequencing adequately. It could say more about permissions or reversibility, but nothing critical to a correct call is missing.

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 both store_uuid and workspace are already documented in the schema. The description adds no parameter-level syntax or format detail beyond that, so the baseline of 3 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?

States a specific verb (activate) and resource (store), plus the concrete consequence: it can 'list products and ingest orders'. This clearly separates it from sibling lifecycle tools like archive_store, unarchive_store, and create_store.

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?

Explicitly states the prerequisite ('Requires at least one fulfillment provider ... to be connected first') and the sequencing ('Use after create_store or unarchive_store once a provider is connected'). It names the alternatives and the condition that selects them, leaving nothing to inference.

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