Update subscriptions' status

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

Annotations already declare destructiveHint=true and non-idempotent behavior, so the safety profile is covered. The description adds genuinely useful context beyond that: it discloses that account state changes, that confirm=true is mandatory, and that OAuth integrations need the subscriptions:write scope. This is meaningful extra disclosure over the structured fields.

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 short sentences, front-loaded with the action and followed by the safety and auth notes. Every sentence carries information and there is no padding, though it is too terse to fully exploit the space.

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 destructive bulk-update tool with 7 parameters, a nested payload object, and no output schema, the description covers purpose, confirmation, and auth but omits bulk semantics, the publication_id requirement, and the mutually exclusive payload/payload_file/body-flag input modes. It is minimally adequate rather than complete.

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 every parameter is already documented in the schema, setting the baseline at 3. The description only echoes the confirm requirement and adds no format or relational detail (e.g. how payload, payload_file, and body flags interact), so it does not add value 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 and resource ('Update subscriptions' status'), which is clear enough on its own. However, it does not differentiate this bulk operation from the many similar siblings such as bulk_subscription_updates_patch_status, update_bulk_subscription_update, or replace_bulk_subscription_update, so an agent cannot tell them apart from the text alone.

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?

The only usage-relevant statement is that confirm=true is required for the user-requested action, which is a precondition rather than when-to-use guidance. There is no indication of when to choose this PUT-status variant over the PATCH or update siblings, so alternative selection is left entirely to inference from tool names.

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