create_pulse

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

No annotations are provided, and the description only states 'Create a new pulse', without disclosing side effects, required permissions, or constraints (e.g., data validation, duplicate handling, creation limits). This leaves significant behavioral details undisclosed.

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 sentence, making it concise. However, it is overly minimal and could be more informative without adding significant length. It is not wasteful, but it also does not fully utilize its space.

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's complexity (nested required parameters, no output schema, no annotations), the description is insufficient. It lacks guidance on what a pulse is, how to structure the input, what the tool returns, and under what conditions it might fail. This leaves the agent without enough context to use the tool correctly.

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 description adds no information about the parameters. The single parameter 'input' is an object with nested required fields (name, cards, channels), but the top-level parameter lacks a description. Schema description coverage is 0%, so the description should compensate, but it does not.

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 states a specific verb and resource ('Create a new pulse in Metabase'), clearly indicating the tool's function. However, it does not differentiate from other create tools (e.g., create_card, create_dashboard) beyond the resource name, and assumes the user knows what a 'pulse' is.

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?

No guidance on when to use this tool versus alternatives like create_card or create_dashboard. There are no prerequisites, exclusions, or context about appropriate use cases, leaving the agent without decision support for tool selection.

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