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 does mention that it reports any unbound placeholder, but it omits details such as whether entities are appended or replaced (the schema's 'replace' parameter is not referenced) and what happens on invalid input. This is partial transparency.

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 paragraph that front-loads the purpose and then explains the rationale and timing. It is not overly long, and every sentence contributes meaning, though it could be tightened without losing substance.

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 presence of an output schema and a detailed input schema, the description adequately explains when to use the tool and what problem it solves. It covers the tool's role in the workflow but does not delve into edge cases or error handling, which are likely covered by the schema and output.

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 covers 100% of parameters with descriptive text (e.g., the entities array structure and roles). The description adds context about templates and how placeholders bind, which is useful but not specific to parameter syntax or constraints. Thus, it stays at the baseline for a fully documented schema.

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 action ('Record') and the resource ('entities named in the Table Instructions') with a specific goal (bind placeholders). It also provides context about the templates and the problem of unbound placeholders, which distinguishes it from sibling tools that handle other aspects of the workflow.

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 says 'Call this before any run' and explains the negative consequence of not doing so, giving clear timing guidance. It does not mention alternatives or exclusions, but the context makes its role unambiguous among the siblings.

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