local-sync

local-sync is a command for Claude Code from bybren-llc/rendertrust. It costs 7 tokens per session (2,117 once invoked), scanned C, a copy of local-sync, Apache-2.0.

A command template for synchronising a local development environment after pulling changes from a development branch. It covers Git branches, dependencies, database updates, and validation, though the supplied excerpt mainly details branch switching and pulling.

In plain words
What is it for?
Check the current branch, stash changes when needed, switch to the development branch, pull from the remote repository, restore stashed work, and clean up merged branches.
Why use it?
It reduces the chance of working on stale code or leaving local branches and uncommitted changes in an unsafe state after a team update.

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 C, and why

local-sync scanned grade C with 1 finding 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 today.

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.

Recursive force deletehighDestructive command

rm -rf with a variable or a broad path is one typo away from removing the wrong tree.

📋 TEMPLATE: This command is a template. See "Customization Guide" below to adapt for your infrastructure.

Perform complete local development environment sync after pulling from dev branch. This ensures dependencies, database, and validation are all up-to-date.

Workflow

1. Git Branch Cleanup (Best Practice)

Check current branch and switch to dev if needed:

CURRENT_BRANCH=$(git branch --show-current)
echo "Current branch: $CURRENT_BRANCH"

If on feature branch:

  • Check for uncommitted changes
  • If clean, switch to dev: git checkout dev
  • If dirty, offer to stash: git stash && git checkout dev
  • Save feature branch name for cleanup

Switch to dev branch:

git checkout dev

2. Git Pull

Pull latest changes from origin/dev:

git pull origin dev

If pull fails due to uncommitted changes:

  • Stash changes: git stash
  • Pull again
  • Reapply stash: git stash pop

3. Branch Cleanup (Git Best Practice)

After pulling latest dev, clean up merged branches:

Check if previous feature branch is merged:

# If we switched from a feature branch, check if it's merged
git branch --merged dev | grep -v "^\*" | grep -v "dev" | grep -v "master"

Offer to delete merged feature branch:

# Example: REN-381-rename-slash-commands-remote-prefix
git branch -d REN-381-rename-slash-commands-remote-prefix

Prune remote tracking branches:

# Remove stale remote tracking branches
git fetch --prune origin

List stale local branches:

# Show branches not updated in 30+ days
git for-each-ref --sort=-committerdate refs/heads/ --format='%(refname:short) | %(committerdate:relative)' | grep -E 'weeks|months|years' ago

Offer to delete stale branches (interactive)

4. Smart Change Detection

Detect what changed to determine necessary steps:

# Check if package.json changed
DEPS_CHANGED=$(git diff HEAD@{1} HEAD -- package.json yarn.lock)

# Check if prisma schema changed
SCHEMA_CHANGED=$(git diff HEAD@{1} HEAD -- prisma/schema.prisma prisma/migrations/)

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.
