/env

/env — Environment Variable Inspector

Manages the env block in ~/.claude/settings.json.

When run without arguments (/env)

Read ~/.claude/settings.json and display the current env block as a table:

Variable	Value	Source
(each key)	(each value)	settings.json

If the env block is empty or missing, say: "No custom environment variables set. All defaults active."

/env reset

Remove the entire env block from ~/.claude/settings.json.
Confirm: "✅ Env block cleared. All variables reset to defaults. Restart Claude Code for changes to take effect."

/env set KEY value

Merge {"KEY": "value"} into the env block in ~/.claude/settings.json.
Always merge, never overwrite other keys.
Confirm: "✅ Set KEY=value in settings.json."

/env unset KEY

Remove a single key from the env block without touching others.
Confirm: "✅ Removed KEY from settings.json."

Important

• Always read the file fresh before writing — never use a cached version.
• After any write, show the full updated env block for confirmation.
• Remind the user: "Restart Claude Code for env changes to take effect."
