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

With no annotations provided, the description carries the full burden of behavioral disclosure. It states the core action but lacks critical details: it doesn't mention permissions needed (e.g., debugger access), potential risks (e.g., crashing the target process), rate limits, or what the output looks like (e.g., raw bytes vs. formatted data). For a low-level memory operation, this is a significant gap.

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, direct sentence with zero wasted words. It's front-loaded with the core purpose and appropriately sized for a straightforward tool, making it easy to parse quickly.

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 complexity of memory operations and the lack of annotations and output schema, the description is incomplete. It doesn't cover behavioral aspects like safety, permissions, or output format, leaving the agent with insufficient context to use the tool effectively in a Frida debugging environment.

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 description coverage is 67% (2 out of 3 parameters have descriptions), so the baseline is 3. The description adds no additional parameter semantics beyond what's in the schema—it doesn't explain the 'session_id' purpose, address format constraints beyond hex, or size limitations (e.g., maximum bytes).

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 action ('Read bytes') and target ('from a specific memory address'), providing a specific verb+resource combination. It distinguishes itself from sibling tools like 'frida_memory_write' by focusing on reading rather than writing, though it doesn't explicitly differentiate from other memory-related tools like 'frida_memory_scan'.

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 provides no guidance on when to use this tool versus alternatives. It doesn't mention prerequisites (e.g., requiring an active Frida session), compare it to similar tools like 'frida_memory_scan' for broader searches, or specify appropriate contexts (e.g., debugging vs. forensics).

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