update_actions_connection

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

No annotations are provided, so the description carries the full burden. It mentions an API requirement (registered application key), which adds some context about authentication. However, it lacks details on behavioral traits such as what fields can be updated, whether the operation is idempotent, error handling, or response format, which are critical for a mutation tool.

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 two sentences with zero waste: the first states the purpose, and the second provides a key requirement. It is front-loaded and efficiently structured, earning a high score for conciseness.

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 that this is a mutation tool with no annotations, no output schema, and 0 parameters, the description is incomplete. It lacks information on what an 'Action Connection' is, what updates are possible, expected outcomes, or error conditions, making it inadequate for effective tool invocation.

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 input schema has 0 parameters with 100% description coverage, meaning no parameters are documented in the schema. The description does not add parameter information, but since there are no parameters, this is acceptable. A baseline of 4 is appropriate as the description does not need to compensate for missing param details.

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 ('Update') and resource ('existing Action Connection'), making the purpose specific and understandable. However, it does not differentiate from sibling tools like 'create_actions_connections' or 'delete_actions_connection', which would require explicit comparison for a higher score.

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 provides no guidance on when to use this tool versus alternatives (e.g., create or delete actions connections). It mentions an API requirement but does not specify prerequisites, conditions, or exclusions for usage, leaving the agent with minimal contextual direction.

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