Claude Config Manager

Manages shared Claude Code settings (~/.claude/settings.json) via the shizuku claude app. All changes go through apps/claude/claude.go.

For the full settings.json schema and all available fields, see: https://code.claude.com/docs/en/settings

How It Works

The claude app reads the existing ~/.claude/settings.json, additively merges managed fields, and writes the result. Existing user-set fields are never removed.

Managed fields and their merge strategies:

Unmanaged fields (e.g. plansDirectory, promptSuggestionEnabled) pass through untouched.

Adding an Allowed Command

1. Open apps/claude/claude.go
2. Add the command string to the desiredAllowedCommands slice
3. Build and verify with diff

Command format examples:

• Bash(command:*) - Allow a bash command with any args
• Bash(git add:*) - Allow a specific git subcommand
• Skill(name) - Allow a skill invocation
• Edit(path/*) - Allow edits to a path pattern
• WebFetch(domain.com:*) - Allow fetching from a domain

Example: adding Bash(docker:*) to allowed commands:

var desiredAllowedCommands = []string{
    "Bash(grep:*)",
    // ... existing entries ...
    "Bash(docker:*)",  // add here
}

Adding a Plugin

1. Open apps/claude/claude.go
2. Add the plugin identifier to the desiredPlugins slice
3. Build and verify with diff

var desiredPlugins = []string{
    // ... existing entries ...
    "new-plugin@marketplace-name",  // add here
}

Adding an Environment Variable

1. Open apps/claude/claude.go
2. Add the key-value pair to the desiredEnv map
3. Build and verify with diff

var desiredEnv = map[string]string{
    // ... existing entries ...
    "VARIABLE_NAME": "value",  // add here
}

Env vars set here are injected into every Claude Code session. Common uses: telemetry config, default model settings, proxy URLs.

Adding a New Managed Field

To manage a new top-level or nested field from settings.json, add merge logic in mergeSettings() after the existing blocks. Follow the established patterns:

For map fields (like enabledPlugins, env):

fieldMap, _ := settings["fieldName"].(map[string]any)
if fieldMap == nil {
    fieldMap = map[string]any{}
}
for k, v := range desiredItems {
    fieldMap[k] = v
}
settings["fieldName"] = fieldMap

For array fields (like permissions.allow):

parent, _ := settings["parent"].(map[string]any)
if parent == nil {
    parent = map[string]any{}
}
items, _ := parent["field"].([]any)
existing := map[string]bool{}
for _, entry := range items {
    if s, ok := entry.(string); ok {
        existing[s] = true
    }
}
for _, item := range desiredItems {
    if !existing[item] {
        items = append(items, item)
    }
}
parent["field"] = items
settings["parent"] = parent

For scalar fields (e.g. setting a boolean):

settings["fieldName"] = desiredValue

Verification

After any change, always:

1. /task build
2. /task run diff -p - Confirm the field appears correctly in the diff
3. /task run sync --verbose - Apply if satisfied

Key File

All changes happen in one file: apps/claude/claude.go
