Read Device Operating Points

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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false, and openWorldHint=false, so the safety profile is fully covered by structured data. The description adds nothing beyond that — no note on row volume, whether output is parsed versus raw text, or how it relates to the sibling readers.

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 short sentence with zero filler and the key action front-loaded. It is efficient, but the terseness borders on under-specification rather than true conciseness, so it earns only a middling score.

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?

With no output schema, the description should describe what is returned (raw rows, parsed fields, units, ordering). It says nothing about return shape or how results relate to summarize_device_operating_points, leaving the agent under-informed for a read tool.

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 coverage is 50%: workspace_root is documented, but log_path (the required parameter) has no description. The phrase "from a log" loosely implies log_path, but the description adds no format, path-resolution, or override semantics to compensate for the coverage gap.

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 gives a concrete verb and resource ("Read operating-point rows from a log"), so the basic purpose is clear. However, it does not differentiate from close siblings such as filter_device_operating_points, summarize_device_operating_points, or read_log, leaving the agent to guess which reader to use.

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?

There is no when-to-use guidance, no prerequisites, and no mention of alternatives despite several overlapping siblings (filter_device_operating_points, summarize_device_operating_points, read_log). Usage must be inferred entirely from the name.

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