SKILL.md covers FIRST: Verify Prerequisites, Critical Rules, Quick Reference and Quick Start: One Repo, plus 2 more sections
Calls git and go; reaches github.com
Explaining committed state versus dirty overlay state in a mount

What it does

ArtifactFS is a filesystem driver that mounts large Git repos quickly and hydrates file contents on first read, and this skill covers using it as a consumer through its CLI. Prerequisites are checked first: macFUSE or /dev/fuse must be present, and the artifact-fs binary must exist or be built with go build. A dedicated state root set through ARTIFACT_FS_ROOT, usually under /tmp, keeps mounts and caches isolated.

The add-repo command registers a blobless clone but does not mount it, while the daemon command mounts all registered repos and keeps running, so one daemon can serve many repos. The mounted tree starts from the committed state of the branch HEAD, local edits live in an overlay and show as dirty state that status reports as overlay_dirty=true, and git add and git commit inside the mount are supported. Other commands list, unmount and remove repos. HTTPS remotes are preferred, and tokens should never be embedded in the remote URL because command-line arguments can show up in process listings.

When your agent uses it

Mounting a remote Git repo without waiting for a full clone
Explaining committed state versus dirty overlay state in a mount
Mounting several repos under one ArtifactFS daemon
Checking status or unmounting a repo

Example prompts

“Mount the main branch of this GitHub repo with ArtifactFS under /tmp.”
“Why does status show overlay_dirty true after I edited a file?”
“Register two repos and mount them with one daemon.”

Requirements

macFUSE on macOS or /dev/fuse on Linux
The artifact-fs binary, or Go to build it
Git remote access, preferably over HTTPS

What it can do on your machine

Read from SKILL.md and the folder at commit 2b87a48. It shows what the files ask for, not the result of running them.

Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
- git
- go
From the folder's file list and the shell code blocks in SKILL.md.
Network
Hosts in commands or code, which the agent is likely to contact:
- github.com
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

ArtifactFS Git Mounts loads about 831 tokens when it runs. Until then it costs about 56 tokens; SKILL.md has 289 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~56
When it runs · the whole SKILL.md, loaded when a task matches: ~831

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

name: artifact-fs
description: Mounts Git remotes with ArtifactFS as local working trees without a full clone. Use when asked to mount a remote repo, explain committed state versus dirty overlay state, or mount multiple repos under one daemon.

ArtifactFS Usage

Use this skill to operate ArtifactFS as a consumer. Prefer the CLI workflow and mounted repos. Do not inspect ArtifactFS internals unless the task is about developing ArtifactFS itself.

FIRST: Verify Prerequisites

Run from the repo root. If either check fails, STOP and fix the environment first.

bash

test -e /Library/Filesystems/macfuse.fs || test -e /dev/fuse
test -x ./artifact-fs || go build -o artifact-fs ./cmd/artifact-fs

Critical Rules

Use a dedicated state root. Set ARTIFACT_FS_ROOT, usually under /tmp, so mounts and caches stay isolated.
Prefer HTTPS remotes. For private repos, use Git credential helpers or SSH auth. Do not embed tokens or passwords in the --remote URL because --remote is a CLI arg and can show up in process listings.
add-repo does not mount. It registers a blobless clone and exits. daemon mounts all registered repos and stays running.
The mounted tree starts from committed Git state. Remote commits, trees, and refs are the base view. Local edits live in an overlay and appear as dirty state until committed.
One daemon can mount many repos. Register each repo separately, then start one daemon --root <mount-root>.

Quick Reference

Task	Command
Register one repo	`./artifact-fs add-repo --name <name> --remote <url> --branch <branch> --mount-root /tmp`
Mount all registered repos	`./artifact-fs daemon --root /tmp`
Check mount and overlay state	`./artifact-fs status --name <name>`
List registered repos	`./artifact-fs list-repos`
Unmount or remove a repo	`./artifact-fs unmount --name <name>` or `./artifact-fs remove-repo --name <name>`

Quick Start: One Repo

bash

export ARTIFACT_FS_ROOT=/tmp/artifact-fs-demo

./artifact-fs add-repo \
  --name workers-sdk \
  --remote https://github.com/cloudflare/workers-sdk.git \
  --branch main \
  --mount-root /tmp

./artifact-fs daemon --root /tmp &
DAEMON_PID=$!

git -C /tmp/workers-sdk rev-parse HEAD
git -C /tmp/workers-sdk status
./artifact-fs status --name workers-sdk

kill $DAEMON_PID
# If a stale mount remains:
umount /tmp/workers-sdk

Mount Semantics

Base view = branch HEAD from the blobless clone. File contents hydrate on first read.
Dirty files are overlay state, not part of the base commit. ./artifact-fs status --name <repo> reports this as overlay_dirty=true.
git add and git commit inside the mount are supported. After commit or checkout, the watcher re-indexes the new HEAD and reconciles stale overlay entries.

Quick Start: Multiple Repos

bash

export ARTIFACT_FS_ROOT=/tmp/artifact-fs-demo

./artifact-fs add-repo --name repo-a --remote https://github.com/org/repo-a.git --branch main --mount-root /tmp
./artifact-fs add-repo --name repo-b --remote https://github.com/org/repo-b.git --branch main --mount-root /tmp

./artifact-fs daemon --root /tmp &
DAEMON_PID=$!

ls /tmp/repo-a
ls /tmp/repo-b
./artifact-fs list-repos

kill $DAEMON_PID
umount /tmp/repo-a
umount /tmp/repo-b
