webex_get_attachment_action

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

With no annotations, the description carries the full burden and delivers almost nothing: no indication that this is a read-only lookup, no note about permissions or token scope, no mention that attachment actions are typically short-lived/expire, and no description of what the returned action object contains. Only the bare operation is disclosed.

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?

A single five-word sentence with the operation and lookup key front-loaded; nothing is wasted. It is efficient but borders on under-specification rather than being a model of concision.

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 is simple (one required param, no nested objects), but with no annotations and no output schema, the description should at minimum convey that it is a safe read returning a card/attachment action object, and where the ID originates. Neither is present, leaving the agent with little beyond the name.

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 description coverage is 100% and the single required parameter actionId is already documented as "Attachment action ID". The description's "by ID" adds no format, source, or validity information beyond the schema, so the baseline of 3 applies.

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 names a specific verb and resource ("Get card action by ID"), so the basic operation is identifiable. However, it calls the resource a "card action" while the tool name and schema say "attachment action" / "Attachment action ID", and it never distinguishes this from the sibling webex_create_attachment_action or explains what an attachment/card action is. Purpose is inferable but not crisply aligned with the tool's own vocabulary.

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?

There is no when-to-use guidance, no prerequisites (e.g. that an actionId typically comes from an attachment-action callback/webhook), and no mention of alternatives. An agent must guess that this is the read counterpart to webex_create_attachment_action.

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