frida_attach

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

No annotations are provided, so the description carries the behavioral transparency burden. It only lists parameters and their types; it does not disclose side effects (e.g., whether the process is paused), prerequisites (e.g., Frida server running), or the lifecycle of the attach (e.g., requires a subsequent detach). This is a significant gap for a state-changing tool.

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: a single purpose sentence followed by a bullet list of parameter explanations. There is no wasted text or redundant information; each bullet earns its place. The structure is scannable and easily parseable by an agent.

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?

The description covers parameter semantics well and the output schema presumably handles return values, but it lacks broader operational context such as when to use attach vs spawn, whether a new session is created, and what happens to the process. For a tool with 6 optional parameters and no annotations, this is a noticeable gap, making it merely adequate.

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%, and the description fully compensates by clearly explaining each of the 6 parameters. For example, 'identifier: Application bundle identifier' and 'realm: Session realm — native or emulated' add meaning beyond bare property names, plus 'device_id' notes default behavior. Every parameter receives a semantic description.

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 action ('Attach') and target ('running process'), adding specificity via 'by PID or name'. This distinguishes it from siblings like spawn, resume, or kill, meeting the highest bar for purpose clarity.

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 implies usage context (use when you need to attach to an existing process) but provides no explicit when/when-not guidance or mention of alternatives. It is not misleading but relies on the agent to infer the appropriate scenario.

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