update_yt_dlp

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

With no annotations, the description bears full responsibility for disclosing effects. It indicates a mutation ('Update') but omits any side effects: whether it requires internet, modifies the local installation, may fail if not installed, or what happens if already up-to-date. This is a significant gap for a tool that changes system state.

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 a single, efficient sentence that leads with the action and resource. There is no wasted wordage, and it is immediately scannable. It earns a top 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 the tool's simplicity (no parameters, no output schema, low complexity), the description covers the core behavior. However, it could briefly mention that the update requires internet connectivity or that it will fetch and install the latest release, which would round out the context. Overall, it is adequate but not exhaustive.

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 tool has zero parameters, so there is nothing for the description to explain about parameters. Per the calibration baseline for 0-parameter tools, a score of 4 is appropriate since the description is not missing any parameter documentation.

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 states a specific verb ('Update') and a precise resource ('yt-dlp') with the goal ('to the latest version'). It clearly distinguishes this tool from all siblings, which handle downloading, searching, or metadata retrieval. The purpose is immediately unambiguous.

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 guidance is provided on when to use this tool versus its siblings. There is no mention of prerequisites (e.g., yt-dlp being installed, network access) or conditions that would trigger an update. The description gives no context for when an agent should select this tool—only what it does.

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