agent-skills

Single source of truth for custom agent skills + commands. Shared across Claude Code and Codex, every machine.

Layout

skills/      # SKILL.md dirs — Claude Code AND Codex both read these (open Agent Skills standard)
commands/    # slash commands — Claude Code only (Codex ignores)
bin/link.sh  # bootstrap symlinks for non-Nix machines
nix/home.nix # home-manager module for NixOS machines
flake.nix    # exposes homeModules.default

Skills are portable: only name+description frontmatter is required by both tools; Claude-only fields (user-invocable, args) are ignored by Codex. Cross-skill refs use root-relative paths (linear-common/COMMON.md), so they resolve under ~/.claude/skills and ~/.agents/skills alike.

Install

Non-Nix machine (e.g. dev VM)

git clone https://git.naps.pt/yolo/agent-skills.git ~/git.naps.pt/yolo/agent-skills
~/git.naps.pt/yolo/agent-skills/bin/link.sh

Symlinks each skill into ~/.claude/skills/ and ~/.agents/skills/, commands into ~/.claude/commands/. Idempotent; any pre-existing real dir is moved to ~/.agent-skills-backup/ (outside the discovery path, so it isn't picked up as a duplicate skill). Re-run after adding a skill.

NixOS machine (home-manager)

# flake inputs
inputs.agent-skills.url = "git+https://git.naps.pt/yolo/agent-skills.git";

# home config imports
imports = [ inputs.agent-skills.homeModules.default ];

recursive = true links files individually, so machine-local skills can coexist in the same dir. nixos-rebuild switch to apply/update.

Adding a skill

Drop a new skills/<name>/SKILL.md (+ optional scripts/, references/, assets/). Commit. Non-Nix: re-run bin/link.sh. Nix: rebuild.
