When to use

Use directory::engine::workers::list to enumerate every worker currently connected to the engine, with its runtime metadata (status, version, runtime, function count, ...). Filter by name, runtime, or status.

This is the LOCAL view. For the registry view (workers PUBLISHED, not connected), use directory::registry::workers::list — rows share a fixed set of core fields (name, description, version) so a parser can walk both surfaces. Each surface adds its own optional fields beyond that.

Inputs

{
  "search":  "agent",     // optional, case-insensitive substring vs name
  "runtime": "rust",      // optional, exact runtime match (e.g. "rust", "node")
  "status":  "connected"  // optional, exact status match (e.g. "connected", "disconnected")
}

Outputs

{
  "workers": [
    {
      "name":              "agent-memory",  // shared core field with directory::registry::workers::list
      "description":       null,            // shared core field; engine carries no description, always null here
      "version":           "0.4.0",         // shared core field
      "id":                "w-abc123",      // engine-assigned connection id (directory-specific)
      "runtime":           "rust",
      "os":                "darwin",
      "status":            "connected",
      "function_count":    9,
      "connected_at_ms":   1715520000000,
      "active_invocations": 0,
      "isolation":         null,
      "ip_address":        null
    }
  ]
}

Rows are sorted lexicographically by name.

The first three fields (name, description, version) are SHARED with directory::registry::workers::list rows so callers can write one parser that handles both surfaces. Everything else is directory-specific runtime-state.

Worked example

Show only connected Rust workers:

{ "runtime": "rust", "status": "connected" }
