Overview ¶
Package pluginapi is the dependency-free wire contract between the agent and a plugin binary: the plugin serves /_plugin/info (echoing the handshake) plus its own routes on the host-provided unix socket.
Index ¶
Constants ¶
const ( // EnvSocket is the unix socket path the plugin must listen on. EnvSocket = "FLATRUN_PLUGIN_SOCKET" // EnvHandshake is a per-launch cookie the plugin echoes so the host knows it spoke to // the process it actually started, not something else bound to the socket. EnvHandshake = "FLATRUN_PLUGIN_HANDSHAKE" // EnvAgentURL and EnvToken let a plugin call back into the agent API. EnvAgentURL = "FLATRUN_AGENT_URL" EnvToken = "FLATRUN_PLUGIN_TOKEN" // EnvDataDir is the deployments base directory, so a plugin can read/write flat state // (e.g. its config under .flatrun/). EnvDataDir = "FLATRUN_DATA_DIR" // InfoPath is the well-known endpoint every plugin serves. InfoPath = "/_plugin/info" // HandshakeHeader carries the echoed handshake cookie on the info response. HandshakeHeader = "X-Flatrun-Plugin-Handshake" )
const ToolExecPath = "/_plugin/tools/exec"
ToolExecPath is where the host POSTs {name, args} to invoke a plugin tool.

Types ¶
type Info ¶
type Info struct {
Name string `json:"name"`
Version string `json:"version"`
DisplayName string `json:"display_name"`
Description string `json:"description"`
Capabilities []string `json:"capabilities,omitempty"`
UIExtensions []UIExtension `json:"ui_extensions,omitempty"`
ConfigSchema map[string]any `json:"config_schema,omitempty"`
Tools []ToolSpec `json:"tools,omitempty"`
}
Info is a plugin's self-reported identity, the capabilities it requests from the host, and how it contributes UI: which native slots it fills and any configuration it accepts.
type ToolSpec ¶
type ToolSpec struct {
Name string `json:"name"`
Description string `json:"description"`
Parameters map[string]any `json:"parameters,omitempty"`
Mutates bool `json:"mutates,omitempty"`
Global bool `json:"global,omitempty"`
}
ToolSpec declares a tool the plugin exposes to the AI assistant. The host advertises it to the model and dispatches calls back to the plugin's /_plugin/tools/exec endpoint. Mutates marks a tool that changes state, so the host can gate it on write access. Global marks a mutating tool that acts on a host-wide setting rather than a single deployment, so the host gates it on a settings-write permission instead of requiring a deployment scope (which such a tool has no way to provide, and which would make it fail in an unscoped assistant session).
type UIExtension ¶
type UIExtension struct {
Slot string `json:"slot"` // "deployment.detail" | "settings" | "overview"
Kind string `json:"kind"` // "metrics-panel" | "form" | "timeline"
Title string `json:"title,omitempty"`
Icon string `json:"icon,omitempty"`
Endpoint string `json:"endpoint,omitempty"`
}
UIExtension declares that a plugin contributes UI into a named slot. The host renders a native component for Kind (plugins never ship UI code) and feeds it from Endpoint, a path on the plugin's own API.
