add_faction

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

No annotations are provided, so the description carries full burden for behavioral disclosure. The description fails to indicate this is a creation/mutation tool, doesn't mention permissions needed, side effects, or what happens upon successful execution. It provides no behavioral context beyond the vague noun phrase.

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?

While technically concise with just one phrase, this is under-specification rather than effective conciseness. The single sentence doesn't front-load critical information about the tool's function. It wastes its limited space on defining a faction rather than explaining the tool's purpose.

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?

For a mutation tool with 1 parameter containing 5 nested properties, 0% schema description coverage, no annotations, and no output schema, the description is completely inadequate. It provides no information about what the tool does, how to use it, what it returns, or any behavioral characteristics.

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%, meaning none of the parameters have descriptions in the schema. The tool description provides no information about the single 'faction' parameter or its nested properties (name, type, description, goals, leader). The description doesn't compensate for the complete lack of schema documentation.

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 'A faction or organization operating within the game world' is a tautology that merely restates the tool name 'add_faction' without specifying what the tool does. It describes what a faction is rather than stating that this tool creates or adds a faction. Compared to sibling tools like 'add_artifact' or 'add_npc', it fails to distinguish its function.

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 provides no guidance on when to use this tool versus alternatives. It doesn't mention prerequisites, when it's appropriate to add a faction, or how it differs from sibling tools like 'update_faction' or 'delete_faction'. There's no context for usage decisions.

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