This skill should be used when editing nix-darwin or Darwin-specific Nix configuration in this dotfiles repo, troubleshooting darwin-rebuild failures, looking up macOS module options, bootstrapping a Mac with Lix/Nix, or using legacy nix-build during nix-darwin work.

Fork one isolated Codex worktree thread per Beads issue and start each with a dependency-aware completion contract. Use when the user asks to start, fork, split, parallelize, or create separate chats for beads, tickets, issues, or a backlog with the goal of fixing them all.
This skill should be used when the user asks to "bump a package", "update an upstream revision", "refresh a Nix source hash", "rebase local patches", "carry fork changes as patches", "hack on upstream software in this repo", or fix a package whose patches no longer apply.
Jujutsu version control through jut, a human and agentic framework around jj. Use for: check status, view changes, commit work, create branches, push, pull, create PRs, squash commits, reword messages, absorb changes, undo operations, view history. Complements jj — use jut for opinionated workflows, drop into raw jj for everything else.
Create, manage, and verify healthchecks.io monitors via the REST API. Use when adding monitoring to a new cron job or service, auditing existing checks, wiring ping URLs into configs, or verifying a check fired correctly.
Control live Herdr workspaces, tabs, panes, agents, worktrees, layouts, plugins, and waits. Use when running inside Herdr (`HERDR_ENV=1`) to inspect sibling agents, delegate work—including dedicated Pi workspaces—run services, debug agent detection, or coordinate terminal state.
Structural code search, refactoring, and repository lint-rule setup with ast-grep. Use when searching by syntax shape, writing or testing ast-grep rules, configuring sgconfig.yml, enforcing coding standards, selecting rule severity, or adding ast-grep to project checks and CI.

Use this skill for Darwin/macOS Nix work in this repo. Keep it out of the global agent rules: this is reference workflow, not behavior that belongs in every prompt.
hostname and uname -a.~/.config, ~/.claude, ~/.pi, and similar paths are usually Nix-store symlinks.hey check for current Darwin host, hey re or full darwin-rebuild for local rebuilds.nix flake check on macOS in this repo because it evaluates NUC outputs and can hit known cross-system noise.Use the narrowest reference that answers the question:

Prefer nix build or repo wrappers for normal flake work.
Important details from the Nix manual:
nix-build is distinct from nix build; use man nix3-build or nix build --help for the modern command.nix-build creates result symlinks by default, which become GC roots until removed.--no-out-link avoids creating the symlink and GC root.-A/--attr, --arg, --argstr, --dry-run, --out-link.
