sync

A Git command for updating a main repository and all of its submodules, which are separate repositories nested inside it. It checks that submodules exist before starting.

In plain words
What is it for?
Use it to pull the main repository and sync nested repositories to their latest tracking branches. The help option shows its usage.
Why use it?
It provides one command for a multi-repository update instead of requiring separate Git commands for each repository.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

sync scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Git Sync Command

Pull superproject and sync all submodules to their latest tracking branches.

Arguments

Parse the following from $ARGUMENTS:

  • --help or -h - Show usage information and exit

Instructions

Step 1: Parse Arguments

From $ARGUMENTS, extract:

  1. help: if --help or -h is present, show the usage information below and stop. Do NOT delegate to the agent.

Help Output

If --help or -h is present, display this and stop:

Usage: /git-workflow:sync [options]

Pull superproject and sync all submodules to latest tracking branches.
Only works in superprojects with submodules.

Options:
  -h, --help            Show this help message

Examples:
  /git-workflow:sync                                Sync all submodules

Step 2: Validate Submodules Exist

git submodule status 2>/dev/null

If output is empty or the command fails, display this error and stop — do NOT delegate:

Error: No submodules found in the current repository.
This command only works in superprojects with submodules.

Step 3: Delegate to Agent

Launch the sync-agent agent:

Task tool:
- subagent_type: "sync-agent"
- description: "Sync submodules to latest"
- prompt: |
    Sync the superproject and all submodules to their latest upstream state.
    - Working directory: <current directory>

Examples

# Sync all submodules to latest
/git-workflow:sync
Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
