share_list_pending_point_transfers

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

Annotations already declare readOnly, idempotent and non-destructive, so the safety profile is covered. The description adds the useful scoping fact that results are limited to transfers pending the caller's acceptance, but says nothing about pagination, result volume, or expiry of pending items.

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?

One short sentence, front-loaded and free of filler. It is arguably too terse for a tool embedded in a 50-sibling ecosystem, but nothing in it is wasted.

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?

An output schema exists so return-shape explanation is unnecessary, and with no parameters the surface is small. Still, an agent gets no signal about the follow-up action (share_handle_point_transfer) or how this list differs from share_list_point_transfer_records, leaving a real gap in a crowded sibling set.

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?

The tool takes zero parameters, which is the baseline-4 case; there is nothing for the description to disambiguate. It does not, however, note that the result set is unscoped by any filter, which would have been the only added value available here.

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 gives a specific verb (查看/list) and a clearly scoped resource: point transfers waiting for the caller to accept. The qualifier '等待我接受' distinguishes it from share_list_point_transfer_records (all records) and share_handle_point_transfer (acting on one), though it never names those siblings.

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?

Usage is only implied by the scope phrase 'waiting for me to accept' – an agent can infer this is the inbox-style list before accepting. There is no explicit when-to-use, no exclusion, and no pointer to share_handle_point_transfer as the natural next step.

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