# openai.yaml fields (full example + descriptions) `agents/openai.yaml` is an extended, product-specific config intended for the machine/harness to read, not the agent. Other product-specific config can also live in the `agents/` folder. ## Full example ```yaml interface: display_name: "Optional user-facing name" short_description: "Optional user-facing description" icon_small: "./assets/small-400px.png" icon_large: "./assets/large-logo.svg" brand_color: "#3B82F6" default_prompt: "Optional surrounding prompt to use the skill with" dependencies: tools: - type: "mcp" value: "github" description: "GitHub MCP server" transport: "streamable_http" url: "https://api.githubcopilot.com/mcp/" policy: allow_implicit_invocation: true ``` ## Field descriptions and constraints Top-level constraints: - Quote all string values. - Keep keys unquoted. - For `interface.default_prompt`: generate a helpful, short (typically 1 sentence) example starting prompt based on the skill. It must explicitly mention the skill as `$skill-name` (e.g., "Use $skill-name-here to draft a concise weekly status update."). - `interface.display_name`: Human-facing title shown in UI skill lists and chips. - `interface.short_description`: Human-facing short UI blurb (25–64 chars) for quick scanning. - `interface.icon_small`: Path to a small icon asset (relative to skill dir). Default to `./assets/` and place icons in the skill's `assets/` folder. - `interface.icon_large`: Path to a larger logo asset (relative to skill dir). Default to `./assets/` and place icons in the skill's `assets/` folder. - `interface.brand_color`: Hex color used for UI accents (e.g., badges). - `interface.default_prompt`: Default prompt snippet inserted when invoking the skill. - `dependencies.tools[].type`: Dependency category. Only `mcp` is supported for now. - `dependencies.tools[].value`: Identifier of the tool or dependency. - `dependencies.tools[].description`: Human-readable explanation of the dependency. - `dependencies.tools[].transport`: Connection type when `type` is `mcp`. - `dependencies.tools[].url`: MCP server URL when `type` is `mcp`. - `policy.allow_implicit_invocation`: When false, the skill is not injected into the model context by default, but can still be invoked explicitly via `$skill`. Defaults to true.
