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

With no annotations, the description carries the full burden. It discloses useful defaults (a status column without options gets To do/In progress/Done) and side effects (unique:true makes upsert_rows match and keeps duplicates out), but says nothing about permissions/scope, what happens on a duplicate column name, or what is returned on success.

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?

Front-loaded purpose followed by dense, high-value semantics for the non-obvious parameters; almost every clause earns its place. The middle section is a run-on that chains several rules into one sentence, slightly hurting scanability.

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?

Covers creation input thoroughly, which is the hard part. However, with no output schema and no statement of what is returned (e.g. table id/URL), an agent that needs the new table's identity to call add_column or add_rows afterwards is left guessing.

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 only 33% (only workspace is described in-schema), so the description must compensate, and it does: it spells out the columns object shape, enumerates all eleven type values, explains the conditional requirement that options lists choices for select/multi/status, and defines unique's matching semantics. The top-level `name` argument is still 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?

Opens with a specific verb+resource ('Make a data table') and immediately narrows the resource with column/type semantics, so an agent can distinguish it from add_column, add_rows and query_rows. It never names a sibling explicitly, so differentiation is inferred rather than stated.

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?

Usage is implied by the resource ('create a table' before adding columns/rows), and the unique-column note hints at the upsert_rows follow-up. But there is no explicit guidance on when to use this versus add_column/get_data_table/list_data_tables, nor any stated prerequisite ordering.

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