Struct SystemPrompt 

pub struct SystemPrompt {
    pub id: String,
    pub description: Option<String>,
    pub strategy_ref: String,
    pub blocks: HashMap<String, String>,
}

A concrete system prompt instance: content mapped to a strategy’s blocks.

Each block value is either:

• Inline text: "You are an expert coder."
• Relative file path: "file:prompts/identity.md" — resolves from agent workspace
• Absolute file path: "file:/etc/phi/identity.md" — resolves as-is

Fields

id: String

Unique id (uses {{...}} reference protocol in config).

description: Option<String>

Description for existence check queries (with % references).

strategy_ref: String

Reference to the strategy that defines this prompt’s structure.

blocks: HashMap<String, String>

Block name → content mapping.

Implementations

impl SystemPrompt

pub fn compose( &self, strategy: &dyn SystemPromptStrategy, working_dir: &Path, ) -> Result<String, Error>

Compose the final system prompt text by resolving blocks against the strategy.

• Sorts blocks by strategy order
• Resolves "file:path" references (relative paths use working_dir)
• Truncates each block to its max_length
• Concatenates with double newlines
