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

Annotations cover the safety profile (readOnly, idempotent, non-destructive), and the description adds genuinely new behavior: the auth/role prerequisite, the tickets=null fallback on missing permission, the soldSeats-by-seat / capacity-minus semantics, and a privacy warning not to relay note/phoneMasked. This goes well beyond the structured data.

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?

Front-loads the access-relevant tag and is free of filler, but the remaining content is delivered as a dense semicolon chain that is harder to parse than it needs to be. Still, every clause carries 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?

With no output schema, the description compensates by explaining the key return values and edge cases (soldSeats, capacity remainder, tickets=null, phoneMasked/note caveats) plus the auth requirement. An agent has what it needs to call and interpret this tool.

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 coverage is 100%, so both parameters are already documented in the schema. The description adds no extra syntax or format detail for activityRef or includeTickets beyond what the schema states, so the baseline 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 (读/read) and resource (票务/线上参会配置 ticketing & online-attendance config), scoped to the organizer role. It explicitly distinguishes itself from update_organizer_ticketing (the write path) and get_organizer_activity (which lacks this config group).

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?

Gives the usage condition (login required, organizer role) and names both relevant alternatives: update_organizer_ticketing for modification and get_organizer_activity as the sibling that does NOT contain this config. When-to-use and when-not are both explicit.

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