set_cache_read

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

No annotations are provided, so the description carries full burden. It describes the behavioral change (default data access class shows cached data from CPU's point of view) and the use case. It does not detail side effects or permissions, but for a simple toggle, this is sufficient.

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 concise and well-structured: a clear one-line purpose, an explanatory paragraph, and a structured argument description. Every sentence adds value without redundancy.

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 tool's simplicity and the presence of an output schema, the description covers the essential behavioral and parameter information. It could mention potential impact on other reads or performance, but for a debug tool, it is adequately complete.

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 0%, so description must fully explain the single parameter 'enabled'. It does so by stating 'True to enable cache-aware reads, False to disable,' adding meaning beyond the schema's title 'Enabled'.

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?

Description clearly states the tool enables/disables cache-aware memory reads, distinguishing it from sibling tools like read_memory and read_memory_cached. It specifies the effect (showing cached data vs stale bus-level data) and provides context for use (debugging cached memory modifications).

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 states it is 'Essential for debugging code that modifies cached memory,' providing clear context for when to use it. However, it does not explicitly mention when not to use it or list alternative tools, leaving some implicit guidance.

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