Open the config editor (creates `~/.phi` layout and writes `~/.phi/config.yaml`): Or set env vars for a one-off run: Then start the TUI: Or build from source (Go 1.26.3+, see `go.mod`): On first start, phi automatically creates `~/.phi/{bin,skills,hooks,session}`. Search tools (`fd`, `rg`) download into `~/.phi/bin` in the background when missing. The TUI gives the model four core tools — `read`, `write`, `edit`, and `bash` — plus `grep`, `find`, and `ls`. The model uses these to fulfill your requests. External HTTP fetch is available via MCP when configured. Footprint Lean is not enough — phi is built to feel instant and stay cheap under load. phi numbers are a stripped release build (`CGO_ENABLED=0`, `-ldflags="-s -w"`) on macOS arm64. Other harnesses use published Linux PSS / interactive PTY figures.
