modify_connection_column_config

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

No annotations are provided, so the description bears the full burden. It discloses that this is a write operation requiring confirmation, and mentions response behavior (contains all known schemas and tables). However, it does not elaborate on side effects, permissions, or rate limits, leaving gaps in transparency.

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 relatively concise, front-loading the critical warning. It adds a few sentences of context without being verbose, though the example details could be more streamlined.

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, so the description should provide sufficient context. It mentions response contents but lacks prerequisites, error conditions, or return value details. For a write operation with 6 required parameters, more completeness would be beneficial.

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 description coverage is 100%, so the baseline is 3. The description adds no extra parameter details beyond the schema definitions; it only references the schema file and specific behavior for certain connectors, which does not enhance parameter semantics.

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 the action: 'Updates the column config within your table for an existing connection within your Fivetran account.' This is a specific verb and resource, and it distinguishes from sibling tools like modify_connection_table_config or modify_connection_schema_config.

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 includes an explicit warning: 'WRITE OPERATION - Confirm with user before calling,' which guides appropriate usage. It also provides specific context for NetSuite and Salesforce connectors, but does not explicitly compare to alternatives or state when not to use.

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