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

No annotations exist, so the description carries the full burden. It usefully discloses output shape and constraints: only each bookmaker's MAIN line (not all lines), decimal odds, upcoming games only, full game by default. It omits response size expectation beyond 'larger response', ordering, and any limits on how many bookmakers/games come back.

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?

Two dense sentences, no filler; the payload description comes first and the period-scope caveat second. Efficient, though the first sentence is packed enough that it takes a second read.

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?

With only two parameters and no output schema, the description does the heavy lifting by explaining what fields come back and in what odds format. Reasonably complete for a listing tool; pagination/volume behavior is the main remaining gap.

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 100%, so both parameters are already documented and the baseline is 3. The description adds little parameter-level detail beyond restating the include_periods behavior; the useful 'line = home team's handicap' clarification describes output semantics rather than an argument.

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 names a concrete resource and scope – upcoming games within a single competition – and enumerates the exact payload (moneyline, handicap/spread, total in decimal odds). It implicitly distinguishes itself from get_game (single game) and list_competitions, though it never names those siblings explicitly.

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?

Usage is only implied: 'Full game only unless include_periods is true' tells the agent when to flip the flag, and the schema points to list_competitions for the competition name. There is no explicit guidance on when to prefer this over get_game or get_game_history, nor any stated prerequisites.

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