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

No annotations are provided, so the description carries the burden; 'List ... saved in this workspace' implies a read-only, non-destructive enumeration, which is the main safety signal an agent needs. However, it says nothing about permissions, pagination/limits, ordering, or whether archived/private schemas are included.

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?

A single front-loaded sentence with no filler; the resource and its scope are established immediately. Nothing could be cut without losing meaning.

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?

With no annotations and no output schema, the description is the only source of return-value information, and it does not say whether full schema definitions, names, or IDs come back. That omission affects whether an agent needs a follow-up get_schema call, so the definition is only minimally sufficient.

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 tool takes zero parameters, so there is no parameter semantics to explain and the baseline of 4 applies. The description correctly does not invent parameter discussion.

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?

States a specific verb ('List') and resource ('extraction schemas') plus a scope qualifier ('saved in this workspace'), which distinguishes it from create_schema/update_schema/get_schema by implication. It never explicitly contrasts with the sibling get_schema, so an agent must infer that this returns the collection rather than one schema.

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 workspace scoping implies discovery use, but there is no explicit 'use this when you need to enumerate before calling get_schema' guidance and no stated exclusions or alternatives. A reasonable inference is available, but nothing is spelled out.

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