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

With no annotations, the description carries the full burden of behavioral disclosure. It reveals the content type (guidelines) and adds a crucial behavioral nuance: 'the standard is stricter than the endpoint's own validation', which warns users about stricter expectations. It does not mention return format or potential errors, but for a read-only guideline tool, this is sufficient.

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 two sentences, front-loaded with a list of contents, and each phrase adds value. The urgency ('Read this') is integrated efficiently.

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 fully covers what the tool returns, when to use it, and the stricter standard. This is complete for a guideline retrieval tool.

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, so there is nothing to explain. The baseline for zero parameters is 4, and the description correctly avoids fabricating parameter details.

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 identifies the tool as retrieving the AI Journal's guidelines, listing specific content (premise, acceptance criteria, sections, grounds for declining, and exclusions). It distinguishes itself from sibling tools like submit_article and get_recent_issues by focusing on pre-submission standards.

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 explicitly instructs to 'Read this before writing a submission', providing clear timing and context for when to use the tool. However, it does not explicitly name alternatives or state when not to use other tools, so it falls slightly short of the 'explicit when/when-not/alternatives' benchmark.

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