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

Annotations already declare readOnlyHint=true and destructiveHint=false, so the safety profile is known. The description adds the 'text file' qualifier and 'persistent machine' context, which is useful, but it does not disclose behavior for missing files, errors, or return format. Given the annotations cover the key safety traits, this is adequate but not rich.

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?

A single, well-structured sentence conveys the essential purpose with no wasted words. It is front-loaded with the primary action and noun, making it easy to parse.

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 read operation with strong annotations and complete schema, the description is nearly sufficient. It states the scope (text file, persistent machine), and the lack of an output schema is acceptable since read operations conventionally return file content. A slight gap is not clarifying whether 'read out' means returning content or moving the file, but the verb 'read' implies the former.

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?

The schema provides 100% parameter coverage with descriptions for 'id' (machine id) and 'path' (absolute path). The description does not add any additional meaning to these parameters, so it meets the baseline of 3 without going beyond the schema.

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 a specific action (read) on a specific resource (text file) from a persistent Linux machine, which distinguishes it from sibling tools like scalix_computer_write_file and scalix_computer_exec. It is concise and 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. While the sibling tools suggest a write counterpart, the description does not mention exclusions (e.g., binary files) or recommend using this tool over exec or cat. The agent must infer usage from the tool name and schema alone.

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