Create Blocklist

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

Annotations are present (readOnlyHint false, destructiveHint false, etc.) and the description adds useful behavioral context: the blocklist auto-populates dynamically and requires a specific plan. This goes beyond what annotations provide, clarifying the resource nature and prerequisites.

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: two sentences that first state the purpose and then add a key prerequisite. Every sentence earns its place without redundancy.

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 presence of an output schema (not shown but indicated), the description does not need to explain return values. It covers the creation action, parameter semantics (via schema), and the prerequisite. It is sufficiently complete for the tool's complexity and sibling context.

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 100%, so the schema fully describes all five parameters. The description adds some meaning to the query parameter (dynamic, auto-populates) but does not significantly enhance understanding of other parameters beyond their schema descriptions. Baseline 3 is appropriate.

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 tool creates a dynamic blocklist from a GNQL query, using specific verb 'create' and resource 'blocklist'. It distinguishes from sibling tools like 'update-blocklist' and 'list-blocklists' by emphasizing the dynamic nature and query-based population.

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 a prerequisite (requires a plan entitled to blocklists) but does not provide guidance on when to use this tool versus alternatives like update-blocklist or when not to use it. It lacks explicit context for selection among siblings.

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