yana-ai-rt

yana-ai-rt [options]yana-ai-rt -h | --helpyana-ai-rt -V | --version

yana-ai-rt is a second Cargo binary from the yana-rt crate. It is built from the same `src/main.rs` as yana-rt. When the executable stem is `yana-ai-rt`, the process inserts the chat subcommand into argv before clap parses, so `yana-ai-rt --provider ollama` is the same invocation as `yana-rt chat --provider ollama`. Extra positional words after the alias still go through clap as chat flags; they are not extra subcommands.`pip install yana-ai` also installs a console script of this name. That shim prepends chat and execs a compiled yana-rt binary: YANA_RT_BIN, then a native yana-rt on PATH (never the pip script itself), then a packaged ELF/Mach-O, then `target/release/yana-rt`. Point YANA_RT_BIN at a compiled binary, never at `which yana-rt` after a pip install. The crate is 1.5.1 on crates.io (2026-10-05); the Python package yana-ai is versioned separately (1.5.2 in pyproject.toml).The REPL talks to a provider from the runtime catalog. With no --provider, it uses ANTHROPIC_API_KEY, else OPENAI_API_KEY, else local Ollama at `127.0.0.1:11434`. A missing key for an explicit cloud provider prints the env var and exits; it does not switch providers. Two tools are available: read_file (read-only, sandboxed to the repo root) and run_command (always asks a human first, then runs through `core/scripts/sandbox-exec.sh` unless --no-sandbox). The process is separate from Claude Code, so PreToolUse hooks never see it.

-h, --help

Print clap help for the inserted chat command

Print the crate version

Chat provider from the runtime catalog (`anthropic`, `openai`, `ollama`, `kimi`, and others)

Override the provider default. For Ollama, the runtime queries `/api/tags` before a static fallback

System prompt for the session

Preload history from a saved session

Print full upstream error detail

Run approved run_command calls without `sandbox-exec.sh`. Approval is still required

YANA_RT_BIN

Absolute path to a compiled yana-rt binary, used by the pip shim

Set by the pip shim to stop recursive re-entry. Do not set by hand

Cloud providers. Kimi uses MOONSHOT_API_KEY

The pip script is not the Rust binary; without a compiled yana-rt it exits 1 and prints install hints. A stale runtime on PATH rejects new flags; upgrade with `cargo install yana-rt --force`. run_command matches command strings, not a full shell parse. Chat is invisible to Claude Code hooks. Default Cargo features include cli; optional mcp, lsp, pty-bridge, and discord are off unless you build with them. npm `bin` entries exist in the repo for local tooling; the product is not published to npm.

yana-ai-rt is the argv[0] chat alias declared next to yana-rt in the Yana AI runtime crate (Apache-2.0, Vũ Văn Tâm, started 17 May 2026). crates.io 1.5.1 (2026-10-05) is the same release as yana-rt.
