slack_lists_items_update

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

With no annotations, the description carries the full burden of disclosing behavioral traits. 'Update a list item' gives no information about side effects (e.g., whether it is destructive), required permissions, rate limits, or return behavior. This is a critical gap 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 extremely concise (one sentence), which is good for conciseness, but it sacrifices necessary detail. It fails to provide even a basic overview of what 'update' entails or how parameters are used.

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?

Given the tool has 3 parameters, no schema descriptions, no annotations, and no output schema explanation (though output schema exists), the description is woefully incomplete. It does not explain the column_values structure, required fields, or what the update operation modifies.

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 has 0% description coverage, and the tool description does not explain the meaning or format of any parameter (item_id, list_id, column_values). The agent is left to infer from parameter names alone, which is insufficient for complex fields like column_values.

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 'Update a list item' clearly states the action (update) and resource (list item), making the purpose immediately understandable. However, it does not differentiate from sibling tools like slack_lists_items_create or slack_lists_items_delete beyond the verb, but the verb is sufficient for basic clarity.

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?

No usage guidelines are provided. The description does not indicate when to use this tool versus alternatives (e.g., when to update vs. create), nor does it mention any prerequisites or restrictions.

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