Project install by default; add -g for ~/.claude/skills/.

GitHub CLI

Project scope by default; add --scope user for a personal install. Needs GitHub CLI 2.90.0 or later (public preview).

Manual copy
$ git clone --depth 1 https://github.com/jeremylongshore/tons-of-skills-marketplace.git skills-src && mkdir -p .claude/skills && cp -r skills-src/plugins/productivity/claudebase/skills/sync-setup .claude/skills/sync-setup && rm -rf skills-src

What it does

Sync Setup is an agent skill from jeremylongshore/tons-of-skills-marketplace. Use when the user wants to set up config sync for the first time, connect to GitHub, or re-initialize the backup repo.

Its SKILL.md is about 430 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It works with GitHub. The repository describes itself as: Model-agnostic agent-skills platform with a harness-free canonical layer, verified adapters, and the ccpi package manager. Explore at tonsofskills.com. The licence is MIT.

When your agent uses it

  • The user wants to set up config sync for the first time
  • Connect to GitHub
  • Re-initialize the backup repo

Example prompts

  • “/sync-setup”

Requirements

  • Pre-approved tools (allowed-tools): Bash(bash "${CLAUDE_PLUGIN_ROOT}/scripts/*"), Bash(gh *), Bash(git *), Read, Write

Workflow steps

4 steps, taken from the first numbered list in SKILL.md.

  1. Verifies gh CLI is installed and authenticated
  2. Creates a private GitHub repo for config storage (or connects to existing)
  3. Initializes the repo structure with a default profile
  4. Performs the first push of your current Claude Code config

What it can do on your machine

Read from SKILL.md and the folder at commit cfae287. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves these tools, so the agent can use them without asking each time:

    • Bash(bash "${CLAUDE_PLUGIN_ROOT}/scripts/*")
    • Bash(gh *)
    • Bash(git *)
    • Read
    • Write

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • bash
    • brew
    • apt
    • dnf
    • winget
    • gh

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use gh, which can reach the network depending on how they are called.

    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

Sync Setup loads about 428 tokens when it runs. Until then it costs about 32 tokens; SKILL.md has 163 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~32
When it runs · the whole SKILL.md, loaded when a task matches
~428

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: notes

The automated check noted patterns worth knowing about, such as sudo or a known installer.

  • NoteRuns commands with sudoSKILL.md:40
    - **Linux**: `sudo apt install gh` or `sudo dnf install gh`

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.

Config Sync Setup

Initialize Claude Config Sync by connecting to GitHub and creating the backup repository.

What this does

  1. Verifies gh CLI is installed and authenticated
  2. Creates a private GitHub repo for config storage (or connects to existing)
  3. Initializes the repo structure with a default profile
  4. Performs the first push of your current Claude Code config

Instructions

Run the setup script. Parse user arguments for custom repo name and profile:

  • First argument (if provided): repo name (default: claude-config)
  • Second argument (if provided): initial profile name (default: default)
bash
bash "${CLAUDE_PLUGIN_ROOT}/scripts/ensure-repo.sh" REPO_NAME PROFILE_NAME

Replace REPO_NAME and PROFILE_NAME with the user's values or defaults.

If gh is not installed

Guide the user to install it:

  • macOS: brew install gh
  • Linux: sudo apt install gh or sudo dnf install gh
  • Windows: winget install --id GitHub.cli

Then authenticate: gh auth login

After setup succeeds

Run the first push automatically:

bash
bash "${CLAUDE_PLUGIN_ROOT}/scripts/sync-push.sh" --profile PROFILE_NAME

Tell the user what was synced and show all available commands: /sync-push, /sync-pull, /sync-status, /sync-profiles, /sync-config.
