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

With no annotations provided, the description bears full responsibility for behavioral disclosure. It does not state whether the operation is read-only, requires authentication, or any other behavioral traits. The label 'Free' is irrelevant to behavior. The tool appears to be a simple retrieval, but critical details are missing.

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 a single sentence that is front-loaded and concise. Every word serves a purpose. However, it could be slightly more informative without losing conciseness (e.g., explaining what DPYC stands for). Still, it is appropriately sized for a parameterless tool.

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) and the presence of an output schema, the description is nearly complete. However, it lacks context about what 'DPYC' and 'Oracle' refer to, which may be important for an agent unfamiliar with the domain. A minimal addition would make it fully self-contained.

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 input schema has zero parameters and 100% schema description coverage, so the schema already fully defines the parameter space. With no parameters, baseline is 4. The description does not need to add parameter information, and it correctly omits any.

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: 'Get DPYC onboarding instructions from the Oracle.' The verb 'get' and resource 'DPYC onboarding instructions' are specific. While it doesn't explicitly differentiate from sibling tools like 'schwab_get_operator_onboarding_status' (which retrieves status, not instructions) or 'schwab_oracle_about' (general information), the purpose is 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?

No guidance is provided on when to use this tool versus alternatives. There is no mention of prerequisites, context, or exclusions. The only additional note is 'Free,' which hints at cost but offers no decision-making support.

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