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

Annotations already declare readOnly/idempotent/non-destructive, and the description adds real behavioral context: login required, DB-only read, no cross-organization scope for annual passes, and the important semantic that PENDING does not mean payment failed. The '只读DB' claim sits in mild tension with openWorldHint=true, but not enough to be a contradiction.

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 content is information-dense and front-loads the login requirement, but it is delivered as a single run-on block of semicolon-separated clauses that is hard to scan. Most clauses earn their place, but structure could be much cleaner.

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 carries the burden of describing returns and does name the main collections (organizationPasses, historical passes/orders, per-activity tickets, myTicket). Combined with its routing and behavioral notes, an agent has enough to call it correctly, though return shape details remain thin.

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 documents limit (default 20, max 100) and activityRefs (slug/id, max 10, per-activity error isolation). The description only loosely reinforces that activityRefs drives per-activity ticket retrieval, adding little 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?

States a specific read verb and enumerates the resources returned: organizationPasses, 历史通票/订单, and 各场票 via activityRefs. An agent can tell it retrieves the caller's pass/ticket/order data, though it does not sharply delineate against neighbors like list_my_signups or get_organizer_ticketing.

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 routes to alternatives with conditions: verify a PENDING state with get_payment_order, buy/top-up with create_payment_order, and fetch activities with list_my_activity_history. It also points eligibility checks to get_activity.canEnterOffline. It lacks an explicit 'do not use this when...' exclusion, so not a full 5.

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