Get an action

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

Annotations already declare readOnlyHint=true and openWorldHint=true, so safety is covered structurally. The description adds nothing beyond that: no note on what an action contains, whether the record can be missing, how errors surface, or whether the call has side effects or remote latency implications.

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 short sentence that is front-loaded and free of padding, but its brevity comes from omission rather than discipline. The parenthetical endpoint is arguably the only sentence with real informational content.

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?

There is no output schema, so the description should describe what a returned action looks like or what fields matter; it does not. For a fetch-by-id tool with an undefined resource name, an agent lacks the context needed to use the result meaningfully.

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 0%, so the description carries the full burden for the single id parameter. The path template '(GET /v1/actions/{id})' does imply id is a path identifier, but it says nothing about format, where the id comes from (presumably actions_list), or validation behavior.

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 pairs a verb and resource ('Get an action') and adds the underlying endpoint (GET /v1/actions/{id}), which confirms it is a single-record fetch rather than a list. However, 'action' is never defined, so an agent cannot tell what domain object is being retrieved, and there is no explicit contrast with the sibling actions_list.

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 when-to-use guidance is given. The implied distinction from actions_list (single item vs collection) must be inferred entirely from the verb, and there are no stated prerequisites, exclusions, or alternative tools.

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