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

The description comprehensively discloses behavioral traits: read-only, stateless, idempotent, rate limits (free vs. pro), and authentication requirements. Since no annotations are provided, the description fully carries the burden of transparency, and it does so thoroughly.

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 well-structured with sections (summary, returns, args, behavior, usage). It is approximately 250 words, which is appropriately sized. However, there is minor redundancy (e.g., 'read-only and stateless' and 'idempotent') and the 'tier' parameter inconsistency slightly detracts.

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?

While the description covers purpose, usage, behavior, and restrictions, it lacks explanation for the 'api_key' parameter and mistakenly references a 'tier' parameter. Since an output schema exists, the description does not need to detail return values, but the parameter gaps reduce completeness.

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 description adds meaning for the 'caller' parameter (rate limiting identifier) but also mentions a 'tier' parameter that does not exist in the input schema. The 'api_key' parameter is not explained. With 0% schema coverage, the description partially compensates but introduces inconsistency.

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 key EU AI Act implementation dates and deadlines.' It specifies the verb ('Get'), the resource ('EU AI Act implementation dates'), and the scope ('key dates and deadlines'). This differentiates it from sibling tools like 'assess_penalties' or 'check_compliance', which focus on different aspects.

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 includes explicit 'When to use' (e.g., compliance assessment, gap analysis) and 'When NOT to use' (substitute for legal counsel) sections. This provides clear guidance on appropriate contexts and exclusions, helping the agent decide between this and sibling tools.

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