C2.9/5.0
Behavior2/5

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

No annotations are provided, so the description carries full burden. It leaves the mutation semantics vague: does it overwrite current game state, require KSP to be running, block until loaded, or fail if already in a scene? For a load/mutation tool with zero annotation coverage this is a significant gap.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

One sentence, front-loaded with the action, with no filler. It is tight, though the phrase 'avoiding title-screen Computer Use' is slightly cryptic jargon for an external agent.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a stateful game-loading tool with no annotations, no output schema, and undocumented parameters, the description omits prerequisites (KSP running), blocking behavior, failure modes, and return value. The sibling tool names suggest a coordinated workflow that this description does not acknowledge.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters2/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0% for the single required parameter save_folder. The description mentions 'save' but gives no format, whether it is a folder name vs path, or where saves live; the agent must guess. A brief example (e.g. 'folder name under KSP/saves') would have closed the gap.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb+resource: load a KSP save via GamePersistence and enter the Space Center scene. Clearly distinguishable from ksp_editor_load (craft loading) and ksp_game_list_saves (enumeration), and the 'real' qualifier plus the save-folder param disambiguate it from listing tools.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The trailing clause 'avoiding title-screen Computer Use' hints at when this is preferred over manual UI navigation, but it never states preconditions, what happens if the game is already in-flight, or which alternatives (e.g. ksp_wait_for_scene, ksp_game_list_saves) pair with it.

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