tool

Adds or modifies an AI tool definition in domain/tools/ai/ and wires its framework-build target. Use when defining a new AI assistant tool (composing AiTool<C> from Has* capabilities), changing an existing tool's capability intersection, adding or updating content-rewrite logic, configuring PluginsCapability with marketplaceSettings, or registering the tool in the registry. Do NOT use for adding a new capability class — use capability instead. Do NOT use for pure string transforms — use format instead. Do NOT use for domain type or model changes — use domain-model instead.
