ecount_test_connection

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

No annotations are provided, so the description carries the full burden. It discloses that the tool checks three specific aspects (auth info, Zone lookup, login) and that it takes no arguments. However, it does not describe return values or failure behavior, which could be expected for a test tool, but overall it is sufficiently transparent for a connection check.

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 concise with three sentences, each adding distinct value: what it does, what it verifies, and when to use it. It is front-loaded with the purpose and contains no redundant 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?

Given the tool's simplicity (no parameters, no output schema), the description covers the essential aspects: purpose, verification steps, usage prerequisite, and invocation. It is missing explicit information about expected response format, but for a connection test with no schema, this is a minor gap.

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 schema has zero parameters, and the description explicitly states 'called with no arguments' (인자 없이 호출합니다), reinforcing the empty schema. This is a solid baseline for a no-parameter tool, adding clarity that the agent does not need to generate any arguments.

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 clearly states the tool's purpose: testing the ECOUNT ERP connection by verifying authentication info and checking Zone lookup and login success. It distinguishes itself from siblings by explicitly positioning as a prerequisite to run before other ECOUNT tools.

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 provides explicit when-to-use guidance: 'Run this before using other ECOUNT tools.' It also states it is called with no arguments, which sets expectations for invocation. No alternative tools are named, but the directive is unambiguous.

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