ChessVox starter repertoires

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

With no annotations, the description carries the full burden. It discloses that entries are free, ChessVox-authored, and that each has color, description, style tags, line count, and UCI preview moves — useful read-only context. However, it does not state pagination, ordering, or whether any auth/quota applies, leaving some behavioral gaps.

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?

Three short sentences, front-loaded with the resource and scope, followed by the per-entry field summary and the usage hint. Nothing is redundant or padded.

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 must convey return structure — and it does, listing the five fields per entry. Missing only secondary details such as list size, ordering, or pagination, which are minor for a zero-parameter listing tool.

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 takes zero parameters, so there are no parameter semantics to explain and the baseline is 4. The description correctly implies a no-argument call by describing a fixed catalogue rather than any filtering inputs.

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 specific verb and resource: 'List the free ChessVox-authored starter opening repertoires', with concrete examples (Italian Game, Caro-Kann) and a link. It is unmistakably distinct from the puzzle siblings (daily_puzzle, mate_rush_puzzles), so no ambiguity for selection.

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?

Explicitly names two use cases: recommending a first repertoire and previewing what a specific opening looks like move by move. It gives clear when-to-use guidance but no exclusions or named alternatives, and the sibling puzzle tools are not addressed as alternatives.

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