set_game_context

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

No annotations, so the description carries full behavioral burden. It says the context is 'set' and affects other tools, which is useful stateful behavior, but omits whether this overwrites existing context, whether it persists across sessions, and what clearing requires (a sibling exists but is not referenced). For a stateful, dependent mutation, that is a significant disclosure 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?

Two tightly written sentences, no filler, with the effect on downstream tools front-loaded.

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?

It conveys purpose and downstream effect but, with no output schema and no annotations, leaves out key details an agent needs: does it overwrite prior context, how does it interact with clear_game_context and get_game_context, and any validation constraints tying players/speaker to player_count.

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 all four parameters are already documented in the schema. The description adds no parameter detail beyond the schema (e.g., speaker must be a seated player, consistency between players and player_count). Baseline 3 is correct.

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 (Set) and resource (game setup context), and the second sentence names the scope: search, list_factions, get_tech_path consume it. An agent can tell this apart from get_game_context and clear_game_context without opening a schema.

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?

Clear context for when to use: before calling tools that need expansions/player count. It implies the alternative (pass params explicitly or use get/clear context), but doesn't state exclusions such as when calling this is unnecessary because context is already set.

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