atlas_variants

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

No annotations are provided, so the description carries the burden. It discloses that the tool returns approaches with pros/cons, which is useful. However, it does not mention side effects, resource implications, or failure modes, leaving a partial transparency gap.

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 two sentences with no filler, front-loading the core action ('Generate multiple solution variants') and adding a meaningful detail about the output. It is minimal yet complete.

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 relatively simple generation tool with fully described inputs and no output schema, the description sufficiently covers the core behavior and output type. It doesn't provide extensive examples or edge cases, but given the low complexity, it is adequate. However, it could benefit from a note on how the results should be used in conjunction with other atlas tools.

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?

All four parameters are already described in the schema (100% coverage), so the baseline of 3 applies. The description adds no additional parameter-specific meaning beyond what schema descriptions provide.

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 (generate multiple solution variants) and a target (coding task), distinguishing it from sibling tools that focus on testing, refactoring, or optimization. The mention of pros/cons further differentiates the output type.

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 implies usage when multiple approaches need to be explored, but does not explicitly state when not to use it or name alternative tools. It provides clear context but lacks exclusions.

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