Setup Requirements

This template requires a few tools to be installed for full functionality. All hooks fail gracefully if tools are missing — nothing will break, but you'll lose validation features.

Required

Tool	Purpose	Install
Git	Version control, branch management	git-scm.com
Claude Code	AI agent CLI	npm install -g @anthropic-ai/claude-code

Recommended

Tool	Used By	Purpose	Install
jq	Hooks (7 of 12)	JSON parsing in commit/push/asset/agent hooks	See below
Python 3	Hooks (2 of 12)	JSON validation for data files	python.org
Bash	All hooks	Shell script execution	Included with Git for Windows

Installing jq

Windows (any of these):

winget install jqlang.jq
choco install jq
scoop install jq

macOS:

brew install jq

Linux:

sudo apt install jq     # Debian/Ubuntu
sudo dnf install jq     # Fedora
sudo pacman -S jq       # Arch

Platform Notes

Windows

• Git for Windows includes Git Bash, which provides the bash command used by all hooks in settings.json
• Ensure Git Bash is on your PATH (default if installed via the Git installer)
• Hooks use bash .claude/hooks/[name].sh — this works on Windows because Claude Code invokes commands through a shell that can find bash.exe

macOS / Linux

• Bash is available natively
• Install jq via your package manager for full hook support

Verifying Your Setup

Run these commands to check prerequisites:

git --version          # Should show git version
bash --version         # Should show bash version
jq --version           # Should show jq version (optional)
python3 --version      # Should show python version (optional)

What Happens Without Optional Tools

Missing Tool	Effect
jq	Commit validation, push protection, asset validation, and agent audit hooks silently skip their checks. Commits and pushes still work.
Python 3	JSON data file validation in commit and asset hooks is skipped. Invalid JSON can be committed without warning.
Both	All hooks still execute without error (exit 0) but provide no validation. You're flying without safety nets.

Optional Performance Settings

CCGS deliberately ships no values for the settings below. Each one's best value depends on your machine, your Claude plan and how you work, so a value committed here would be a guess every user inherits without noticing. Set the ones you want in .claude/settings.local.json, which is gitignored and yours alone.

Setting	What it does	When to change it
promptCacheTtl	How long the main conversation's prompt cache lives.	Raise it if you work in long sessions with gaps; the cache surviving a break avoids re-sending context.
subagentPromptCacheTtl	The same, for subagents and other off-conversation requests.	Worth raising on a 49-agent project like this one, where team-* skills spawn repeatedly.
autoCompactWindow	How full the context gets before Claude Code compacts it.	Lower it if compaction keeps surprising you mid-task; raise it if you would rather compact less often and keep more history.
skillListingBudgetFraction	How much context the skill listing may occupy.	CCGS ships 74 skills, so the listing is not small. Lower it if you want more room for work; skillListingMaxDescChars trims each description instead.

sandbox.enabled isolates shell commands from your filesystem and network. It is worth turning on, but it runs on macOS, Linux and WSL2 only — it is not available on native Windows, which is CCGS's primary platform.

One setting CCGS does ship

permissions.defaultMode is set to default in .claude/settings.json, on purpose. It makes Claude Code ask before acting, which is what every approval gate in this framework depends on. Project settings outrank personal ones, so this holds even if your own config sets acceptEdits or auto — otherwise CCGS's collaboration protocol would be silently switched off for you and the agents would write files you never approved.

If you genuinely want it off, override it in .claude/settings.local.json, which takes precedence. Understand what you are turning off first.

Recommended IDE

Claude Code works with any editor, but the template is optimized for:

• VS Code with the Claude Code extension
• Cursor (Claude Code compatible)
• Terminal-based Claude Code CLI
