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

With no annotations provided, the description carries the full burden of behavioral disclosure. It discloses that it returns a reference document and that no API key is required, which implies a read-only, low-friction operation. It does not mention rate limits, output size, or any state changes, but for a zero-parameter info tool these are minor gaps.

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?

A single, efficient sentence that front-loads the primary behavior (returns a reference document), then lists the covered topics, and ends with an important auth requirement. Every word adds value with no redundancy or filler.

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 simple zero-parameter, no-output-schema tool, the description fully covers what an agent needs: what it returns, its content scope, and whether authentication is needed. Nothing essential is missing.

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 coverage is trivially 100%. The description correctly adds no parameter-specific details because none exist; the baseline for a no-parameter tool is 4, and the description doesn't need to compensate.

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?

States a specific verb ('Returns') and resource ('Strale's trust methodology') and lists the document's contents (test cadence, audit records, provenance). While it doesn't explicitly distinguish itself from siblings like strale_getting_started or strale_trust_profile, the described content uniquely identifies it as a methodology reference.

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 gives contextual hints about when to use it (when you need trust methodology, test cadence, audits, provenance) and notes that no API key is required. However, it does not explicitly state when not to use it or name alternative tools, leaving the routing to inference.

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