Struct LlmEmbedding 

pub struct LlmEmbedding { /* private fields */ }

Implementations

impl LlmEmbedding

pub fn detect_available() -> Result<Self, AppError>

Detects which LLM CLI is available on PATH and returns the matching embedding client.

v1.0.76: PREFERS codex over claude because:

• Claude Code 2.1+ ships a 180k+ token system context (plugins, skills, agents, MCP) that overflows the 200k context window for even trivial embedding prompts and returns “Prompt is too long”.
• Codex 0.134+ is lightweight (~5k system context) and the StructuredOutput tool reliably returns 384-dim vectors.

pub fn with_codex() -> Result<Self, AppError>

pub fn with_claude() -> Result<Self, AppError>

pub fn embed_passage(&mut self, text: &str) -> Result<Vec<f32>, AppError>

Embeds a single passage (chunk of a memory body). Returns a 384-dim f32 vector suitable for cosine similarity.

pub fn embed_query(&mut self, text: &str) -> Result<Vec<f32>, AppError>

Embeds a single query. The LLM uses a different prompt prefix to disambiguate query from passage.
