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

With no annotations provided, the description carries the burden of disclosing behavior. It explicitly reveals the scheduled daily 08:00 KST matching and email sending, plus the Pro-only restriction. It also indicates that remove deletes and add persists, giving useful non-obvious context beyond the raw schema.

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 a single dense sentence that front-loads the core purpose, then lists actions, and ends with the key behavioral note and Pro restriction. Every clause adds information; there is no filler or redundancy.

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?

For a 9-parameter multi-action tool with no annotations and no output schema, the description covers the action taxonomy and unique scheduling behavior, but omits parameter-level requirements per action and return expectations for list/matches. This is sufficient for a basic understanding but not complete for correct invocation of all actions, especially 'add' and 'matches'.

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 only 44%, so the description must compensate. It adds some semantic grouping: 'add로 조건+이메일 저장' connects email and condition parameters to the add action, and 'remove로 삭제' implies watch_id use. However, it does not explain the meaning or combination of keyword, region, category, min_price, or max_price, nor how 'matches' relates to parameters, leaving significant gaps given the low schema coverage.

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 states a clear verb and resource: 'manages bid notification conditions' and enumerates the four actions (add, list, remove, matches) with brief effects. This clearly differentiates watch_bids from sibling tools like search_bids or get_bid_detail, which are about searching and retrieving bid data rather than managing alert conditions.

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 implies when to use the tool: when the user needs to set up or manage bid notifications, with the daily email matching behavior noted. However, it does not explicitly contrast with alternatives such as search_bids for one-off searches, nor does it state when not to use this tool. The guidance is implied rather than explicit.

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