Terminal Prompts

# Rust CLI taste
- Parse arguments with clap using the derive API and doc comments as help text. Confidence: 0.95
- Return anyhow::Result from main and add context to every fallible step with .context(). Confidence: 0.90
- Define library error types with thiserror and keep anyhow in the binary only. Confidence: 0.85
- Split the crate into a thin main.rs and a lib.rs that holds the real logic for testing. Confidence: 0.85
- Write normal output to stdout and logs, progress and errors to stderr. Confidence: 0.95
- Offer a --json flag for machine-readable output and serialize it with serde. Confidence: 0.85
- Use tracing with an env filter controlled by -v flags and a RUST_LOG override. Confidence: 0.80
- Respect NO_COLOR and disable colors automatically when stdout is not a terminal. Confidence: 0.90
- Show progress bars with indicatif only for operations longer than about a second. Confidence: 0.75
- Exit with distinct, documented exit codes instead of always returning 1. Confidence: 0.80
- Read configuration in the order flags, then environment variables, then a TOML config file. Confidence: 0.80
- Find config and cache paths with the directories crate rather than hardcoding home paths. Confidence: 0.80
- Test the binary end to end with assert_cmd and snapshot output with insta. Confidence: 0.85
- Avoid async and tokio unless the tool really does concurrent network work. Confidence: 0.75
- Generate shell completions and a man page with clap_complete and clap_mangen at build time. Confidence: 0.75
- Ship prebuilt binaries for Linux, macOS and Windows with cargo-dist from GitHub Actions. Confidence: 0.80
- Run cargo clippy with warnings denied and cargo fmt --check in CI. Confidence: 0.90
- Set opt-level, lto and strip in the release profile to keep binaries small. Confidence: 0.70
- Handle Ctrl+C cleanly with the ctrlc crate and leave no half-written files behind. Confidence: 0.80

# Shell scripting taste of a DevOps engineer
- Start every script with #!/usr/bin/env bash and set -euo pipefail. Confidence: 0.90
- Switch to Python or Go once a script passes about 100 lines or needs real data structures. Confidence: 0.85
- Run ShellCheck in CI and fix warnings instead of silencing them. Confidence: 0.95
- Format scripts with shfmt so diffs stay small. Confidence: 0.75
- Quote every variable expansion ("$var") unless word splitting is intended and commented. Confidence: 0.95
- Use [[ ]] for tests and $(...) for command substitution, never backticks. Confidence: 0.90
- Declare variables inside functions with local. Confidence: 0.85
- Put the logic in functions and call a main "$@" at the bottom of the file. Confidence: 0.80
- Clean up temporary files with mktemp and trap '...' EXIT. Confidence: 0.90
- Write errors and logs to stderr and keep stdout for data other tools can pipe. Confidence: 0.85
- Exit with a non-zero status and a clear message when something fails. Confidence: 0.90
- Provide a usage function and handle -h and --help. Confidence: 0.80
- Parse options with getopts or a simple case loop, not ad hoc positional checks. Confidence: 0.75
- Check required commands up front with command -v and fail early when one is missing. Confidence: 0.85
- Read configuration from environment variables with defaults, such as -8080. Confidence: 0.80
- Never parse ls output; use globs or find -print0 with xargs -0. Confidence: 0.90
- Read files line by line with while IFS= read -r line. Confidence: 0.85
- Use arrays for argument lists instead of building command strings. Confidence: 0.85
- Avoid eval, and never pass untrusted input to it. Confidence: 0.95
- Make scripts idempotent so running them twice is safe. Confidence: 0.85
- Add a --dry-run flag to anything that deletes or changes remote state. Confidence: 0.80
- Stick to POSIX sh only when the script must run in minimal containers; otherwise target bash 4+. Confidence: 0.70

# Neovim Config taste of a minimalist terminal-first developer
- Write the whole config in Lua, starting from a single init.lua that requires small modules under lua/config and lua/plugins. Confidence: 0.90
- Use lazy.nvim as the plugin manager and commit lazy-lock.json so every machine gets the same plugin versions. Confidence: 0.90
- Lazy-load plugins by event, command, filetype or key mapping, and keep startup time under 50 ms measured with :Lazy profile. Confidence: 0.80
- Prefer the built-in LSP client with nvim-lspconfig over heavier all-in-one language plugins. Confidence: 0.85
- Install language servers, formatters and linters with mason.nvim, but pin the tool list in config instead of installing by hand. Confidence: 0.80
- Format on save with conform.nvim and lint with nvim-lint, using the same tools and settings the project runs in CI. Confidence: 0.85
- Use nvim-treesitter for highlighting, indentation and text objects, and list the parsers you need explicitly. Confidence: 0.85
- Pick one fuzzy finder, such as telescope.nvim or fzf-lua, and route files, grep, buffers and LSP symbols through it. Confidence: 0.85
- Set the leader key to space before loading any plugin so every mapping uses it. Confidence: 0.90
- Give every custom mapping a desc field so which-key and :map show what it does. Confidence: 0.85
- Group mappings by prefix, like leader f for find, leader g for git and leader l for LSP, and avoid overriding core Vim motions. Confidence: 0.80
- Keep options in one options.lua file using vim.opt, with a short comment for anything that is not obvious. Confidence: 0.80
- Use relative line numbers, a sign column that is always shown, and persistent undo files. Confidence: 0.75
- Use autocommand groups with clear = true so reloading the config never duplicates handlers. Confidence: 0.90
- Respect .editorconfig files and avoid hard-coding indentation per language unless a project has no settings. Confidence: 0.80
- Show git changes in the sign column with gitsigns.nvim and stage hunks from the editor. Confidence: 0.80
- Use the built-in completion engine or blink.cmp, with LSP and snippet sources only, to keep the popup fast and relevant. Confidence: 0.70
- Choose one colorscheme with good Tree-sitter and LSP semantic token support, and do not chase new themes every week. Confidence: 0.65
- Add a plugin only when it replaces a repeated manual step, and remove plugins you have not used in a month. Confidence: 0.80
- Keep machine-specific settings in a git-ignored local.lua file so the main config stays portable. Confidence: 0.75
- Run :checkhealth after upgrades and fix warnings before adding new plugins. Confidence: 0.80
- Store the config in a dotfiles repository and upgrade plugins deliberately, reviewing the lazy.nvim changelog first. Confidence: 0.85
