interact_with_process

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

With no annotations, the description carries the full burden of behavioral disclosure. It states only the action ('send stdin') but does not mention side effects, error behavior (e.g., what happens if the process doesn't exist), or whether it blocks, making the tool's behavior opaque beyond the basic action.

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, front-loaded sentence with zero wasted words. However, while concise, it is under-specified; the conciseness is acceptable but not exemplary because a few more details (e.g., parameter roles) would make it more useful without bloating it.

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 its simple two-parameter schema and lack of output schema, the description is insufficiently complete. It omits any usage context (e.g., how to obtain the process id, when to send stdin), and does not describe return values or error conditions, leaving the agent with significant gaps in understanding.

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 provides no additional meaning for the 'id' or 'input' parameters. The parameter names are self-explanatory to some degree, but the description does nothing to clarify their types, formats, or constraints, failing to compensate for the lack of schema descriptions.

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 uses a specific verb 'send' and clearly names the resource 'stdin to a process.' It distinguishes itself from sibling tools like start_process, read_process_output, and kill_process, making the tool's purpose unambiguous.

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?

No guidance is provided on when to use this tool versus alternatives. It does not mention prerequisites (e.g., process must be running) or exclusions, leaving the appropriate usage context entirely to the agent's inference.

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