My Claude Code project's starter settings and Claude Code hooks and slash commands.
- Copy the files to your project directory.
- Modify the template files and
CLAUDE.md
to your liking..claude/settings.json
needs to install Terminal-Notifier for macOS https://github.com/centminmod/terminal-notifier-setup. If you're not using macOS, you can remove.claude/settings.json
. - Run
/init
so that Claude Code analyses your code base and then populates your memory bank system files as perCLAUDE.md
instructions.
I also install the following MCP servers:
The Claude Code hook is for STOP
which uses Terminal-Notifier to show macOS desktop notifications whenever Claude Code stops and finishes it's response https://github.com/centminmod/terminal-notifier-setup.
Claude Code subagents are specialized tools designed to handle complex, multi-step tasks autonomously. A key benefit of Claude Code subagents is that uses its own context window separate from the main conversation and can use it's own custom prompt. Learn more about subagents in the official documentation.

Configure Claude Code with global and project-level settings, and environment variables.
Claude Code offers a variety of settings to configure its behavior to meet your needs. You can configure Claude Code by running the /config
command when using the interactive REPL.
The settings.json
file is our official mechanism for configuring Claude
Code through hierarchical settings:
- User settings are defined in
~/.claude/settings.json
and apply to all projects. - Project settings are saved in your project directory:
.claude/settings.json
for settings that are checked into source control and shared with your team.claude/settings.local.json
for settings that are not checked in, useful for personal preferences and experimentation. Claude Code will configure git to ignore.claude/settings.local.json
when it is created.
settings.json
supports a number of options:
Key | Description | Example |
---|---|---|
apiKeyHelper |
Custom script, to be executed in /bin/sh , to generate an auth value. This value will generally be sent as X-Api-Key , Authorization: Bearer , and Proxy-Authorization: Bearer headers for model requests |
/bin/generate_temp_api_key.sh |
cleanupPeriodDays |
How long to locally retain chat transcripts (default: 30 days) | 20 |
env |
Environment variables that will be applied to every session | {"FOO": "bar"} |
includeCoAuthoredBy |
Whether to include the co-authored-by Claude byline in git commits and pull requests (default: true ) |
false |
permissions |
See table below for structure of permissions. |
Keys | Description | Example |
---|---|---|
allow |
Array of permission rules to allow tool use | [ "Bash(git diff:*)" ] |
deny |
Array of permission rules to deny tool use | [ "WebFetch", "Bash(curl:*)" ] |
additionalDirectories |

defaultMode |
Default permission mode when opening Claude Code | "acceptEdits" |
disableBypassPermissionsMode |

"disable" |
Settings are applied in order of precedence:
- Enterprise policies (see IAM documentation)
- Command line arguments
- Local project settings
- Shared project settings
- User settings
Claude Code supports the following environment variables to control its behavior:

We are in the process of migrating global configuration to settings.json
.
claude config
will be deprecated in place of settings.json
To manage your configurations, use the following commands:
- List settings:
claude config list
- See a setting:
claude config get <key>
- Change a setting:
claude config set <key> <value>
- Push to a setting (for lists):
claude config add <key> <value>
- Remove from a setting (for lists):
claude config remove <key> <value>
By default config
changes your project configuration. To manage your global configuration, use the --global
(or -g
) flag.
To set a global configuration, use claude config set -g <key> <value>
