Synthesis

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

The description implies write/mutating behavior through 'Manage' and actions like revert/activate/deactivate, but it does not disclose side effects, persistence, or destructive consequences. Since readOnlyHint is false, this is not contradictory, but agent expectations about state changes are left unstated.

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 compact and front-loads the resource and action list with no unnecessary prose. The 'Use when' sentence is somewhat redundant with the enum values, but it still serves as clear usage guidance.

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?

Covers resource, action scope, when to avoid, and the sibling alternative. It does not describe output/return shape or define terms like 'synthesis items' in depth, but with schema descriptions and sibling context it is reasonably complete.

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?

All 9 parameters are covered by short descriptions, and several include parenthetical action mappings such as 'Item key (activate: number; player_add/player_remove: string)' and 'Return full entries (list)'. Descriptions are terse but functional.

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?

Identifies the resource as synthesis content and lists examples like voice examples, lore templates, action patterns, and other Ruleset Wisdom. It enumerates the supported actions, but the core verb 'Manage' is broad and relies on the action list to make the purpose concrete.

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?

Provides an explicit 'Use when' list covering the action categories and a 'Do NOT use when' clause directing codex browsing to the sibling codex tool. This gives an agent clear positive and negative selection guidance.

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