Struct EmbedTemplate 

pub struct EmbedTemplate {
    pub argv: Vec<String>,
    pub stdin: Option<String>,
    pub env: BTreeMap<String, String>,
    pub cwd: Option<String>,
    pub output: Option<SubprocessOutput>,
    pub system_prompt: Option<String>,
    pub model: Option<String>,
    pub tools_csv: String,
}

GH #83 — the compile-time-baked EmbedAgent invocation: a resolved SubprocessDef template merged with the agent profile (system prompt / model / tools) and the Runner::Subprocess overrides. When ProcessSpawner::embed carries one of these, spawn takes the EmbedAgent path: materialize the worker payload via Engine::fetch_worker_payload (never the fetch_prompt-only single-directive path), render the closed placeholder set into argv/stdin/env/cwd, and normalize stdout per SubprocessOutput. When None, spawn keeps the historical spec-based behavior byte-for-byte.

Fields

argv: Vec<String>

Full argv (element 0 = program), unrendered — elements may carry placeholder tokens.

stdin: Option<String>

stdin template. Some = render + pipe to the child’s stdin; None = no stdin write (immediate EOF).

env: BTreeMap<String, String>

Extra env vars (appended to the MSE_* token exports); values may carry placeholder tokens.

cwd: Option<String>

Working-directory template (Runner::Subprocess overrides.cwd already merged in at compile time — it wins over the template’s own cwd). None = fall back to the spawn-time {work_dir} source; if that is also absent the child inherits the server CWD (historical behavior).

output: Option<SubprocessOutput>

stdout normalization declaration. None = historical JSON-or-raw.

system_prompt: Option<String>

Compile-time-baked profile.system_prompt (pre-render template — minijinja slot expansion happens at spawn, mirroring OperatorSpawner).

model: Option<String>

{model} placeholder value (overrides.model > profile.model).

tools_csv: String

{tools_csv} placeholder value (overrides.tools > profile.tools, CSV-joined).
