Env Manager

DevOps & Security

env-manager

Env Manager is an Agent Skill for devops & security published in the dtyq/magic repository on GitHub: a SKILL.md instruction file an AI agent can load to do this task.

Use when the user provides API keys, tokens, or other configuration values that should persist across sessions, or when the user asks to query, list, or delete saved environment variables. Manages personal env by default and workspace env only when explicitly requested.

QUICK START

How to use this skill

Bring this guide into your coding agent with a prompt tailored to the tool you use.

Open your project in Codex.
Copy and paste the prompt below.
Review files and risks before approving any action.

Prompt to paste

Inspect the Agent Skill at https://github.com/dtyq/magic/blob/HEAD/backend/super-magic/agents/skills/env-manager/SKILL.md and all supporting files. Report provenance, permissions, scripts, dependencies, and security risks. Propose an exact installation into .agents/skills/env-manager, but wait for my approval before writing files or running scripts.

Copying this prompt does not install or run the skill. Review third-party files before use.

Environment Variable Manager

Use this skill by calling set_env, get_env, unset_env, and list_env through sdk.tool.call(...) inside run_sdk_snippet.

By default, save and delete personal environment variables stored in ~/.magic/super-magic.env for reuse across workspaces. Pass "scope": "workspace" only when the user explicitly asks to save or delete values for the current workspace/project.

The runtime effective environment merges workspace env and personal env. Personal env has the highest priority and overrides workspace values with the same key. Tool display and results never echo plaintext values.

Get One Env

When you only need to check whether one key is configured, prefer get_env. get_env queries the final effective env by default (scope=all). Do not call list_env just to inspect one key, because that exposes unrelated environment variable names and masked values to the model context.

run_sdk_snippet(python_code="""
from sdk.tool import tool

result = tool.call("get_env", {
    "key": "KEY_NAME",
})
if not result.ok:
    raise SystemExit(result.content)
print(result.content)
""")

Only pass "scope": "personal" or "scope": "workspace" when you need to check whether a key exists in a specific storage scope.

run_sdk_snippet(python_code="""
from sdk.tool import tool

result = tool.call("get_env", {
    "key": "KEY_NAME",
    "scope": "workspace",
})
if not result.ok:
    raise SystemExit(result.content)
print(result.content)
""")

Set Personal Env

run_sdk_snippet(python_code="""
from sdk.tool import tool

result = tool.call("set_env", {
    "key": "KEY_NAME",
    "value": "value",
})
if not result.ok:
    raise SystemExit(result.content)
print(result.content)
""")

Set Workspace Env

run_sdk_snippet(python_code="""
from sdk.tool import tool

result = tool.call("set_env", {
    "key": "KEY_NAME",
    "value": "value",
    "scope": "workspace",
})
if not result.ok:
    raise SystemExit(result.content)
print(result.content)
""")

List Personal Env

run_sdk_snippet(python_code="""
from sdk.tool import tool

result = tool.call("list_env", {})
if not result.ok:
    raise SystemExit(result.content)
print(result.content)
""")

List Workspace Env

run_sdk_snippet(python_code="""
from sdk.tool import tool

result = tool.call("list_env", {
    "scope": "workspace",
})
if not result.ok:
    raise SystemExit(result.content)
print(result.content)
""")

List Effective Env

"scope": "all" means the final effective merge of workspace and personal env. Personal env overrides workspace env with the same key.

run_sdk_snippet(python_code="""
from sdk.tool import tool

result = tool.call("list_env", {
    "scope": "all",
})
if not result.ok:
    raise SystemExit(result.content)
print(result.content)
""")

Unset Personal Env

run_sdk_snippet(python_code="""
from sdk.tool import tool

result = tool.call("unset_env", {
    "key": "KEY_NAME",
})
if not result.ok:
    raise SystemExit(result.content)
print(result.content)
""")

Unset Workspace Env

run_sdk_snippet(python_code="""
from sdk.tool import tool

result = tool.call("unset_env", {
    "key": "KEY_NAME",
    "scope": "workspace",
})
if not result.ok:
    raise SystemExit(result.content)
print(result.content)
""")
