tokportal_reactivate_account_managed_subscription

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

The description adds significant behavioral context beyond annotations, including that reactivation is free under certain conditions, atomic checks of credits/period/lock version, and that scheduled videos get new dates. No contradictions with annotations (readOnlyHint=false, etc.).

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 description is moderately long but efficient, with each sentence adding value. It is front-loaded with the main action and then explains conditions and edge cases. No redundant or unnecessary information.

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?

Given the complexity of the tool (no output schema, nested parameters), the description covers all necessary aspects: the need for a GET snapshot, billing implications, atomic checks, and video scheduling behavior. It is sufficiently complete for an AI agent to operate 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 100%, so the schema already fully documents all parameters. The description mentions expected_credits, expected_current_period_end, and expected_lock_version but does not add new semantic meaning beyond what the schema provides.

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 clearly states 'Reactivate TokPortal Coverage' and explains the action of reactivating from an explicit GET snapshot. It distinguishes itself from sibling tools like cancel_account_managed_subscription and get_account_managed_subscription by focusing on reactivation.

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 description provides context on when to use the tool, such as the free reactivation during a paid billing period and handling of lapsed states at period end. It implies the need for a prior GET snapshot but does not explicitly list alternatives or when not to use the tool.

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