SCORM packager self-test

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

The description discloses that it writes a specific file (selftest-scorm2004.zip) into the output directory, which complements the annotations (readOnlyHint=false, destructiveHint=false, idempotentHint=true). It also mentions reporting version, duration, and output path, providing additional behavioral context beyond the annotations.

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?

Three concise sentences effectively convey purpose, use case, and side effects. The key information is front-loaded, and every sentence contributes meaning without 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 zero-parameter diagnostic tool, the description fully covers what it does, the output file, the reported data, and the time frame. There is no output schema, but the reporting details are sufficient. The description is complete for an agent to decide when and how to invoke it.

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 has zero parameters and the schema is empty with 100% coverage. The description explicitly states 'NO arguments', which is consistent and adds clarity for an agent, meeting the baseline for no-parameter tools.

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 is a diagnostic self-test: it packages a constant built-in HTML and reports version, duration, and output path. It distinguishes itself from the sibling tool by being diagnostic with no arguments, which is specific and unambiguous.

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 tool is positioned as a diagnostic to differentiate 'server broken' from 'input problem' in one second, giving a clear use case. However, it does not explicitly name the alternative (scorm_package) or state when not to use it, so it falls short of a 5.

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