get_component_definition

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

The description does not disclose any behavioral aspects such as side effects, permissions, or whether the operation is read-only. While the name suggests a get operation, the description does not explicitly state that it is safe or free of side effects, and there are no annotations to fill this gap.

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 reasonably structured but contains redundant boilerplate about the object store and output formatting (e.g., repeating 'Use the object store tools...' twice). While not excessively long, this repetition could be trimmed for conciseness without losing essential information.

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 description covers the tool's purpose, parameters, and return type, but it lacks context about why or when one would need a component definition (e.g., for inspecting inputs/outputs before pipeline creation). It does not explain the structure of the returned definition or its typical use in the broader workflow.

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 provides meaningful explanations for both parameters. For component_type, it gives a concrete example. For haystack_version, it explains how to derive the value from the pipeline's dependencies. This adds clarity beyond the schema, which only lists types and required status.

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 function: 'Returns the definition of a specific Haystack component.' This is a specific verb-resource pair, and it distinguishes from sibling tools like get_pipeline or list_pipelines by focusing on component definitions.

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 does not provide guidance on when to use this tool versus alternatives. It lacks any mention of use cases, prerequisites, or scenarios where this tool is appropriate, leaving the agent to infer its purpose from the name and generic description.

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