Write Code Portfolio

Portfolio Dev Setup

Personal, opinionated tooling that backs the patterns in write-code. This is not portable. Other users on Bitwarden + asdf + bash will not want any of this.

Composable Toolsets (Nix Flakes)

13 reusable per-language shells combined via flake.nix outputs. Each shell pins a single toolchain (rust-toolchain, go, node, python with uv, etc.). Projects compose the shells they need; nothing pollutes the global env.

• Each language shell exposes a devShell and a lib.tools set for downstream composition
• Avoid nix-direnv here -- vanilla direnv + a use flake line keeps cold-start fast and predictable on macOS

Machine Polymorphism (chezmoi)

Dotfile templates branch on host attributes:

{{ if .is_macos -}}
# macOS-only block (Homebrew bundle, defaults write, ...)
{{ end -}}

{{ if and .is_personal (not .is_work) -}}
# personal-only block (1Password personal vault, side projects, ...)
{{ end -}}

Attributes come from .chezmoi.toml.tmpl (is_macos, is_linux, is_personal, is_work). Keep templates small and the booleans flat; deeply nested {{ if }} blocks are a smell.

Powerlevel10k

Zsh prompt with instant prompt enabled and cache invalidation tied to plugin dir mtime. Source of truth: dot_p10k.zsh in the chezmoi source. Avoid editing the rendered ~/.p10k.zsh directly -- it is overwritten on next chezmoi apply.

Neovim (HEAD)

Lua config under private_dot_config/nvim/. Highlights:

• LSP set: ty, ts_ls, lua_ls, gopls, rust_analyzer, jsonls, yamlls, bashls, jdtls
• Subprocess-safe: detects non-interactive sessions and disables clipboard provider (so nvim -c '...' +q in scripts doesn't hang on macOS pbcopy)
• Plugin manager: lazy.nvim, pinned via lazy-lock.json
• 24-hour compinit cache; auto fpath discovery picks up new completions on next shell start

Why split this out

The portable write-code skill answers "what should this codebase look like?" That question is the same for everyone in the org. This skill answers "how is my personal machine wired up?" -- a question only I should be making decisions for, so the router shouldn't pick it for general code-writing requests.
