import_study

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

No annotations are provided, so the description carries the full behavioral burden. It says what is imported, including variations and transpositions, but does not disclose side effects, permissions, duplicate handling, or whether the import creates or overwrites data. For an import/mutation tool, 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.

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

The description is a single, front-loaded sentence with no filler. It is efficient and easy to scan, though its brevity leaves much unsaid for a 4-parameter import tool.

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?

An output schema exists, so return values need not be described. However, with no annotations and 0% schema description coverage, the description is far too sparse for a 4-parameter import operation. It omits parameter meanings, side effects, and usage context.

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 must explain all 4 parameters. It only implicitly touches on 'pgn' and 'source' via 'PGN study' and 'source-attributed', while 'name' and 'is_repertoire' are not addressed. It adds little beyond the parameter titles already present in the schema.

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?

States a clear verb+resource: importing a PGN study. It adds scope with 'source-attributed' and 'including variations and transpositions', distinguishing it from generic parsing tools. It does not explicitly name sibling alternatives such as import_opening_plan or parse_game, so it stops short of a 5.

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 gives no when-to-use guidance, no prerequisites, and no alternatives. It does not say when to choose import_study over parse_game, import_opening_plan, or other import tools. Only the implicit context of importing a PGN study is available.

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