pane_send_keys

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

Annotations already declare readOnlyHint=false, destructiveHint=false, idempotentHint=false, and openWorldHint=false, so the core safety profile is covered. The description adds only example key strings and does not explain delivery timing, focus requirements, or effects such as ctrl+c interrupting a running process.

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 definition is a single front-loaded sentence with no filler, and the examples are embedded efficiently. Nothing in the description is wasted.

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 two-parameter mutation tool with no schema descriptions, the definition is missing pane_id semantics and usage boundaries versus pane_send_text and agent_send_keys. The output schema and annotations cover return values and safety profile, but the description remains too thin for this tool's input surface.

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 the description must carry parameter meaning. It gives useful examples for the keys array, but it says nothing about pane_id or the accepted key grammar, leaving key parameter semantics incomplete.

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 states a specific verb and resource: "Send logical key presses to a pane," and gives examples of key values. It is clear what the tool does, but it does not differentiate from sibling tools such as pane_send_text or agent_send_keys.

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?

It only says what the tool does, with no when-to-use guidance, prerequisites, or comparison to alternatives. The examples hint that this is for key sequences rather than text, but they do not route an agent between pane_send_text and agent_send_keys.

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