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

With no annotations provided, the description carries full burden but offers minimal behavioral insight. It implies a mutation ('reactivate') but doesn't disclose permissions required, whether changes are reversible, rate limits, or error conditions. The return statement mentions 'confirmation with updated seat status' but lacks detail on format or possible outcomes. For a mutation tool with zero annotation coverage, this is inadequate.

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 front-loaded with the core action, followed by structured Args and Returns sections. It avoids fluff and each sentence adds value, but the formatting with separate sections could be slightly more integrated for flow. Overall, it's efficient and well-organized.

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 3 parameters with 0% schema coverage, no annotations, and an output schema present, the description does a fair job. It explains parameters and hints at return values, but as a mutation tool, it lacks critical behavioral details (e.g., side effects, error handling). The output schema reduces need for return explanation, but overall completeness is moderate with room for improvement.

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%, but the description compensates well by explaining all three parameters: 'user_id' as 'User ID who owns the seat', 'account_id' as 'Account/Seat ID to reactivate', and 'proxy_country' as 'Optional proxy country code' with examples. This adds meaningful context beyond the bare schema, though it doesn't detail format constraints (e.g., ID patterns) or proxy country implications.

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 the action ('reactivate'), resource ('inactive seat'), and scope ('within a specific team'). It distinguishes from siblings like 'cancel_seat' and 'suspend_or_unsuspend_seat' by focusing on reactivation of inactive seats. However, it doesn't explicitly contrast with 'create_seat' or other seat-related tools, keeping it from a perfect score.

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 no guidance on when to use this tool versus alternatives like 'suspend_or_unsuspend_seat' or 'create_seat'. It mentions the tool is for 'inactive seats' but doesn't clarify prerequisites (e.g., seat must be inactive) or exclusions (e.g., not for active seats). This lack of contextual usage information is a significant gap.

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