frida_memory_alloc_string

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

With no annotations, the description must disclose side effects and behavioral traits. It only states that it allocates a string and returns an address, without mentioning memory ownership, cleanup requirements, error cases, or permission needs. This is minimal disclosure.

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 with a single purpose line, a bullet-like list for parameters, and a return statement. Every sentence adds value, and it is front-loaded with the core action.

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 allocation tool, the description covers purpose and parameters adequately. However, it omits important behavioral context like whether the allocated string must be freed manually or what happens on failure. Given no output schema and no annotations, this is a minor gap.

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 coverage is 0%, but the description fully explains each parameter: target (process name/pid), string (value), encoding (default utf8, with utf16 and ansi options). This adds significant meaning beyond the schema's type-only definitions.

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 'Allocate a string inside a target process' with a specific verb and resource. It distinguishes itself from sibling tools like frida_memory_alloc by focusing on string allocation, and mentions the return value (address).

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 other memory allocation tools (e.g., frida_memory_alloc for raw bytes) or when not to use it. There are no preconditions or exclusions mentioned.

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