get_elfa_rates_and_rules

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

No annotations are provided, so the description carries the full behavioral burden. It conveys that the tool is a read-only retrieval of official rates, tables, and rules ('Get'), but it does not disclose output format, data source behavior, update cadence, or access requirements. This is minimally viable but not richly transparent.

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 front-loaded sentence with no wasted words. It packs in the jurisdiction, department, fiscal year, and three content types without repetition or tangential information.

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 no-parameter retrieval tool, the description is mostly complete, but the absence of an output schema means the description has to carry return-value meaning. It names the content areas but not the structure or format, and it does not clarify how this tool relates to check_elfa_eligibility despite the overlapping income eligibility language.

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?

There are zero parameters and the schema is an empty object, so the input schema already fully documents the call signature. The description correctly adds no parameter details; the 0-parameter baseline of 4 applies.

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 states a specific verb ('Get') and a concrete resource: San Francisco DEC official FY 2026-2027 reimbursement rates, income eligibility tables, and program rules. This clearly distinguishes it from sibling tools like check_elfa_eligibility and search_sf_childcare, which focus on checking eligibility or searching childcare options.

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 no explicit when-to-use or when-not-to-use guidance, and it does not mention alternatives. It leaves the relationship to check_elfa_eligibility ambiguous, especially since both involve income eligibility content. The intended usage is only implied by the tool's purpose.

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