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

Annotations already declare readOnlyHint=true and openWorldHint=false, so the safety profile is covered. The description adds a useful 'not legal advice' disclaimer and cites the underlying regulations, but it does not explain the output format or how the deadlines are calculated.

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 dense but front-loaded, with the core purpose stated first and regulatory citations earning their place. It could be split for readability, but it avoids unnecessary 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?

With no output schema, the description should carry more weight, and it does cover all five parameter concepts and the legal context. It still lacks an explicit statement of the return structure, but it is sufficient for an agent to understand what the tool computes.

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?

Schema description coverage is 100%, setting a baseline of 3, but the description adds regulatory meaning by tying parameters to ICS timing under FAR 52.216-7, grant report cadence and closeout under 2 CFR 200.328/200.344, and single audit thresholds under 2 CFR 200.501. This helps an agent understand why each input matters.

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 it returns federal award deadlines scoped by fiscal year end and award type, with specific regulatory citations. It does not explicitly distinguish itself from sibling tools, but the domain is specific enough for an agent to identify the tool's purpose.

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 implies usage for federal contractors or grant recipients needing compliance deadlines, but it does not state when to use this tool versus alternatives like form_5500_check or product_compliance_requirements. No explicit exclusions or prerequisites are provided.

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