4096bytes Skills

A small collection of reusable agent skills (Codex CLI compatible).

What is a “skill”?

A skill is a self-contained, versioned workflow that teaches the agent how to do a specific task reliably. In practice, each skill lives in its own directory and is defined by a SKILL.md file (metadata + instructions), optionally backed by scripts and reference specs.

Included skills

git-commit

Install skills from this repo:

$skill-installer install https://github.com/4096-bytes/skills/tree/main/skills/git-commit

Generates a Conventional Commits-style draft message using Git only (no build tools), preferring staged changes. It writes the draft to Git’s COMMIT_EDITMSG and prints a suggested git commit ... command.

• Entry: skills/git-commit/SKILL.md
• Script: skills/git-commit/scripts/git_commit.py

Natural-language examples (prompts you can give the agent):

• “I’ve staged a focused change. Draft a Conventional Commit message for what’s in the index.”
  • $git-commit
• “Treat this as a fix in scope cli, and add an emoji prefix.”
  • $git-commit --type "fix" --scope "cli" --emoji
• “Stage everything and generate the draft for me.”
  • $git-commit --all
• “This is a small follow‑up; amend the previous commit (and include DCO sign‑off).”
  • $git-commit --amend --signoff
• “Generate the draft, but I need to commit without running local hooks.”
  • $git-commit --no-verify

git-worktree

Install skills from this repo:

$skill-installer install https://github.com/4096-bytes/skills/tree/main/skills/git-worktree

Manages Git worktrees under ../.atmu/<project-name>/ with safe path handling and optional IDE opening. Includes helpers to migrate uncommitted changes via stash and to copy gitignored .env / .env.* files into new worktrees.

• Entry: skills/git-worktree/SKILL.md
• Script: skills/git-worktree/scripts/git_worktree.py

Natural-language examples (prompts you can give the agent):

• “Create an isolated worktree for a new feature branch called feat/ui and open it in my IDE.”
  • $git-worktree add "feature-ui" -b "feat/ui" -o
• “I want the worktree folder name to be hotfix, but the branch name to be fix/login.”
  • $git-worktree add "hotfix" -b "fix/login"
• “Move my uncommitted work from main into the feature-ui worktree.”
  • $git-worktree migrate "feature-ui" --from "main"
• “I’m done with feature-ui; remove the worktree and clean up.”
  • $git-worktree remove "feature-ui"
• “I deleted a worktree folder manually; prune stale worktree references.”
  • $git-worktree prune

git-clean-branches

Install skills from this repo:

$skill-installer install https://github.com/4096-bytes/skills/tree/main/skills/git-clean-branches

Safely identifies merged and/or stale Git branches and prints a deletion plan by default (dry-run). Requires --yes to apply deletions, supports protected branch patterns via git config branch.cleanup.protected, and can optionally delete remote branches as well.

• Entry: skills/git-clean-branches/SKILL.md
• Script: skills/git-clean-branches/scripts/git_clean_branches.py

Natural-language examples (prompts you can give the agent):

• “Show me which branches are merged into main and safe to delete.”
  • $git-clean-branches --dry-run
• “Find branches inactive for 90+ days and show what would be deleted.”
  • $git-clean-branches --stale 90
• “Delete merged branches against release/v2.1, including remote branches.”
  • $git-clean-branches --base "release/v2.1" --remote --yes
• “Force-delete a specific local branch that I know is obsolete.”
  • $git-clean-branches --force "outdated-feature" --yes
