get_cache_rules

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. 'Get' implies a read operation, but the description does not mention pagination, authentication requirements, rate limits, or whether the result is a list or single object.

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 one short, front-loaded sentence with no filler or redundancy. It could carry more useful context, but what is present is efficiently written.

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 simple one-parameter read tool, this is minimally viable, but there is no output schema and no annotations to compensate for the lack of return-format or behavior details. The description also does not clarify how cache rules relate to similar constructs like cache settings or zone rulesets.

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 already documents zone_id with 100% coverage, so the baseline is 3. The description adds no extra parameter context beyond the phrase 'for a zone,' which is already captured by the parameter name and 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 states a specific verb ('Get'), a concrete resource ('cache rules'), and a scope ('for a zone'). It is clear, but it does not explicitly differentiate itself from nearby siblings like get_cache_settings or get_rate_limiting_rules.

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?

There is no guidance on when to use this tool versus alternatives, and no exclusions or preconditions are mentioned. Given the large sibling list with similarly named zone-scoped retrieval tools, the agent gets no decision support.

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