pocketsmith_create_category_rule

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

With no annotations, the description carries full burden for behavioral disclosure. It states the rule applies to 'future transactions' but the schema includes parameters 'apply_to_uncategorised' and 'apply_to_all' that affect existing transactions, creating a potentially misleading omission. The description fails to disclose the destructive impact of re-categorizing existing transactions.

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 a single, front-loaded sentence with no filler. Every word contributes to the core purpose, making it highly scannable for an AI agent.

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 4 parameters (2 required) and no output schema, the description is insufficient. It does not explain what a category rule is, how the matching works, or the implications of the apply_to parameters. With siblings like 'list_category_rules', the description should provide more context about the rule lifecycle.

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 baseline is 3. The description adds minimal value beyond the schema, only clarifying 'future transactions' which is not entirely accurate given the apply_to parameters. No additional parameter details or usage examples are provided.

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 verb 'Create', the resource 'category rule', and the purpose 'automatically categorize future transactions matching a payee pattern'. It effectively distinguishes from sibling tools like 'categorize_transaction' (one-time) and other creation tools.

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 use when setting up recurring categorization but provides no explicit guidance on when to use versus alternatives, nor does it offer exclusion criteria or mention prerequisites. It is adequate but lacks directive clarity.

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