create_application_category

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

With no annotations, the description carries full burden. It discloses pattern constraints and default values for boolean parameters. However, it omits key behavioral details such as whether creation is idempotent (e.g., duplicate name handling), error conditions, or required permissions. Adequate but not thorough.

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 well-structured with a short summary followed by an Args list. It is reasonably concise, though the Args block could be slightly tightened. Every sentence adds value, and the format is easy to parse.

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?

The tool has an output schema, but the description does not mention what it returns (e.g., the created category object). It also lacks error scenarios (e.g., invalid pattern, duplicate name). While sibling tools provide context, the description alone is incomplete for a creation operation.

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 0%, so the description must compensate, and it does thoroughly. It explains all six parameters, including format constraints for 'name' (lowercase, min 3 chars) and 'custom_patterns' (space-separated globs, exactly one '/'), plus defaults and optionality. This adds significant meaning beyond the bare schema.

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's action: 'Create a new application category' and explains its function for grouping applications using namespace/name patterns. It provides specific format requirements for patterns, making the purpose highly concrete and distinguishable from sibling tools like update or delete.

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 implies when to use the tool (to create a new category) but does not explicitly state when to use it over alternatives (e.g., update_application_category) or mention prerequisites (e.g., existence of a project). No 'when not to use' guidance is provided.

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