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

No annotations are provided, so the description carries full burden. It discloses that existing data is transformed to match the new schema, which is a useful behavioral trait. However, it omits critical safety information such as potential data loss from dropping/narrowing fields, default in-place behavior, permissions required, or reversibility. This is insufficient for a mutation tool.

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 only two sentences, front-loaded with the primary verb and resource, and lists operations efficiently. Every word earns its place with no filler or repetition.

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 tool with 6 parameters and no annotations or output schema, the description provides a good high-level summary but lacks important behavioral and usage context such as default in-place behavior, destructive implications, or prerequisites. The schema descriptions fill in parameter details, but the description alone is not fully complete for safe invocation.

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 input schema provides descriptions for all 6 parameters (100% coverage), so the baseline is 3. The description's mention of operations (widen/narrow/rename/add/drop) maps conceptually to the alter/add/drop parameters but adds no new parameter-level details beyond what the schema already documents.

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 it modifies a data file's schema, enumerating specific operations (widen/narrow/rename/add/drop) and explicitly distinguishing this schema-level tool from sibling record-level tools like chaprola_insert_record or chaprola_update_record. The verb 'Modify' plus resource 'data file's schema' is specific 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?

The description implies usage for schema changes, but provides no explicit when-to-use guidance, exclusions, or comparisons to alternatives. Given the large sibling set with overlapping data manipulation tools, clearer direction would be valuable, but the schema-modification context is reasonably evident.

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