get_github_action_versions_and_args

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

With no annotations provided, the description carries the full burden. It discloses the behavioral trait of fetching latest Git tag and action.yml metadata, and optionally README. However, it does not mention authentication needs, rate limits, or what happens for invalid inputs. Some additional context would be beneficial.

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 concise with two sentences, front-loading the primary purpose. Every sentence adds value and there is no unnecessary 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?

Given the tool's simplicity (2 parameters, output schema exists), the description covers the main functionality adequately. It could briefly mention the output format or that it only works for github.com-hosted actions, but the existence of an output schema reduces the need for return value details.

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 covers both parameters with descriptions. The tool description adds context by mentioning 'latest versions and metadata' and README, but does not significantly enhance the understanding of the parameters beyond the schema. Baseline for 100% coverage is 3.

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 it gets the latest versions and metadata for GitHub Actions, specifying the exact data fetched (latest Git tag and action.yml) and optional README inclusion. This distinguishes it from sibling tools like get_latest_package_versions which target packages.

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 clear context on what the tool does and its optional parameter, but does not explicitly state when to use this tool versus alternatives or when not to use it. Given the distinct purpose from siblings, this is acceptable but not maximally helpful.

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