Trigger Hotkey by Key Sequence

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

Annotations already indicate this is a destructive, non-idempotent operation, but the description adds no extra behavioral context. It does not explain side effects, whether keys are pressed and released, how the hotkey sequence is processed, or what happens if the key does not exist. The description contributes almost nothing beyond the structured annotations.

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 short sentence with no wasted words, but it provides minimal informational value and largely repeats the tool name. It could use more detail about the key sequence format without being verbose.

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 destructive tool with a nested modifiers object and a clear alternative (trigger by name), a complete description should explain what counts as a sequence, how modifiers combine with keyId, and what side effects occur. The current one-line description is insufficient for an agent to use this tool safely and accurately.

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 100%, with keyId and keyModifiers both documented inline. The description adds no additional parameter meaning beyond the schema, so the baseline score of 3 applies.

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 says 'Triggers a hotkey using a sequence of keys,' which essentially restates the tool name and title without clarifying what 'key sequence' means or how it differs from the sibling obs-trigger-hotkey-by-name. It names the action and resource but fails to provide a specific, distinguishing definition.

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 gives no guidance on when to use this tool versus obs-trigger-hotkey-by-name or other triggering tools. It does not mention prerequisites, limitations, or typical use cases, so an agent has no context for choosing it over alternatives.

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