upbit_caution_watchlist

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

With no annotations, the description carries the full behavioral burden. It usefully states that the tool reports current flags and first-observed times, but it does not disclose ordering, freshness semantics for 'currently', pagination behavior, or whether authentication/rate limits apply.

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 definition is front-loaded with the core purpose and then lists only three parameters. It is efficient and avoids unnecessary filler, though the Args block is plain and repeats defaults that also appear in the schema.

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 read-oriented watchlist tool with three simple parameters and an output schema, the description supplies the key content, filters, and defaults an agent needs to invoke it correctly. The main remaining gaps are operational details such as asset symbol format, ordering, and data freshness.

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%, so the description must compensate, and it does: it documents the flag enum (caution | warning | all), the optional single-symbol asset filter, and the limit default of 50. It could still clarify the expected asset symbol format, but it adds substantial meaning beyond the bare 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?

The description states a specific resource and scope: every KRW market currently carrying an Upbit investment caution or warning flag, plus when the flag was first observed. It is clear what the tool returns, though it does not explicitly differentiate itself from siblings such as korea_premium or krw_listing_changes.

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 implied through the watchlist framing and filter parameters, but there is no explicit when-to-use or when-not-to-use guidance, and no alternative tool is named. An agent can infer that this is for monitoring caution/warning flags, but must rely on context to choose it over siblings.

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