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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It mentions descending order support but does not state whether input is mutated, what the output format is, how missing columns are handled, or whether the sort is stable.

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 short and mostly front-loaded, with the core operation stated first. The opening 'CSV Sort:' is a slight redundancy with the tool name, but the rest is economical and readable.

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?

There is no output schema, no annotations, and the input schema has no meaningful descriptions. The description does not explain whether 'column' refers to a header name or an index, what the 'data' parameter is for, what the default sort order is, or what the tool returns.

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 100%, but every schema description is a tautology like 'Col to process' or 'Csv to process'. The description adds useful meaning by saying 'column (or col)' and noting order=desc is the descending option, but it leaves the relationship between 'csv' and 'data' unexplained.

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 verb ('Sort'), resource ('CSV data'), and criterion ('by a specified column'). This distinguishes it from sibling tools like csv-filter, sort-lines, sort-strings, and sort-numbers based on operation and resource.

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 clear context: use this when you need to sort CSV data by a column. It also provides direct invocation guidance ('Provide csv text and column (or col); optional order=desc'), though it does not explicitly name alternatives or when-not-to-use conditions.

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