lade 0.16.0

Automatically load secrets from your preferred vault as environment variables, and clear them once your shell command is over.
lade-0.16.0 is not a library.

Lade

Crates.io

Give shell commands and AI agents temporary access to secrets, files, and private networks, then clean everything up automatically.

Lade (/leɪd/) matches the command you run, loads only what it needs, masks provider-resolved secrets from command output, and removes command-scoped files and network forwards when the process exits.

Why Lade?

Modern commands need short-lived access: a deploy needs tokens, a migration needs a private database, an AI agent needs to run a tool without seeing the secrets behind it. Lade keeps that access scoped to the command instead of your whole shell session, CI job, or model context.

  • Load secrets from 1Password CLI, Infisical, Doppler, Vault, Passbolt, local files, shell commands, or inline values.
  • Write temporary JSON/YAML files for tools that expect credentials on disk.
  • Open private network access through kubectl, kubefwd, Teleport tsh, or SSH only while the command runs.
  • Redact provider-resolved secrets from stdout and stderr.
  • Work from shells, CI, Cursor, and Claude Code.

Compatible shells: Fish, Bash, Zsh. Lade targets Unix systems: macOS and Linux.

Getting started

curl -fsSL https://raw.githubusercontent.com/zifeo/lade/main/installer.sh | bash
lade install

lade install adds shell hooks once. After that, matching commands are wrapped automatically. Pause and resume hooks with lade off and lade on.

Alternative installs:

cargo install lade --locked
cargo install --git https://github.com/zifeo/lade --locked

Upgrade with:

lade upgrade

How it works

Create a lade.yml at your project root. Each top-level key is a regular expression matched against the command being run.

"psql .*":
  DB_USER: op://my.1password.com/eng/postgres/username
  DB_PORT: kubectl://k8s.example.com:6443/prod/default/service/postgres/5432
  DATABASE_URL: postgres://${DB_USER}@127.0.0.1:${DB_PORT}/app

Now run the command normally:

psql "$DATABASE_URL"

Lade resolves DB_USER, opens a local forward for DB_PORT, interpolates both into DATABASE_URL, runs the command, masks resolved secret values from output, and cleans up when psql exits.

Shell hooks are the recommended path because you keep typing normal commands. When hooks are unavailable, prefix the command with lade for one-shot injection. The explicit form is lade inject <command>.

lade terraform apply
lade inject -- terraform apply

Common patterns

Shell hooks - Run commands normally. Lade injects access only when the command matches lade.yml.

Shell hooks

Provider resolution - Match commands and load values from vaults, files, or inline config only when needed.

Provider resolution

Manual injection - Use lade <command> in scripts, CI, or shells without hooks. The explicit form is lade inject <command>.

Manual injection

Private networks - Open a local forward only while the command runs, then close it automatically.

Private network

Secrets as files - Write temporary config files for commands that expect credentials on disk.

Secrets as files

Per-user values - Keep one shared lade.yml while developers, CI, and environments resolve different values.

Per-user secrets

Human approval - Add a disclaimer before sensitive commands. Hooks withhold access until the approval code is used.

Disclaimer

Shell command provider - Use stdout from a local command as a secret value.

Shell command provider

AI agents

AI coding agents often need to run commands that require secrets, private network access, or both. Lade lets the command access what it needs without putting secret values in the model context or chat transcript.

Recommended usage: transparent hooks

Cursor and Claude Code can call lade hook before shell commands. When an agent runs a matching command, Lade rewrites it through lade inject, resolves the configured access, and redacts provider-resolved secret values from stdout and stderr.

The agent keeps using normal commands. Lade handles the sensitive part.

lade install can add the hook for detected agents. The equivalent project configs are:

Cursor

{
  "version": 1,
  "hooks": { "preToolUse": [{ "command": "lade hook", "matcher": "Shell" }] }
}

Claude Code

{
  "hooks": {
    "PreToolUse": [
      {
        "matcher": "Bash",
        "hooks": [{ "type": "command", "command": "lade hook" }]
      }
    ]
  }
}

Cursor agents can also load the project skill in .cursor/skills/lade/SKILL.md.

Agents without hooks

For agents without shell hooks, add a short instruction to AGENTS.md:

When a command needs access defined in lade.yml, prefix it with lade.
Example: lade terraform apply

Transparent hooks are preferred because the agent does not need to guess which commands match lade.yml.

Configuration reference

Lade has two provider families used from the same lade.yml rule:

  • Secret providers resolve values into environment variables or temporary files.
  • Network providers create command-scoped connectivity and clean up automatically.

Secrets

"terraform .*":
  TF_VAR_api_key: op://DOMAIN/VAULT/ITEM/FIELD

Most secret providers use their native CLI. Ensure the required binaries are installed and authenticated before running commands. Provider-resolved values are masked from command output unless --no-mask is set. Inline values are not masked because they are already visible in lade.yml.

Supported secret providers:

Provider URI Notes
1Password op://DOMAIN/VAULT/ITEM/FIELD Uses the 1Password CLI.
Infisical infisical://DOMAIN/PROJECT_ID/ENV_NAME/SECRET_NAME The /api suffix is added automatically.
Doppler doppler://DOMAIN/PROJECT_NAME/ENV_NAME/SECRET_NAME Uses the Doppler CLI.
Vault vault://DOMAIN/MOUNT/KEY/FIELD Uses the Vault CLI.
Passbolt passbolt://DOMAIN/RESOURCE_ID/FIELD Uses the Passbolt CLI.
File file://PATH?query=.fields[0].field Supports INI, JSON, YAML, and TOML files.
Shell command sh://gcloud auth print-access-token Also supports bash://, zsh://, and fish://.
Inline value "visible-in-lade-yml" Use ! to force raw values and !! to escape !.

Use lade eval <uri> to resolve one URI when debugging a provider.

Files and disclaimers

Options under . configure the matched command itself.

"deploy .*":
  .:
    file: secrets.yml
    disclaimer: "This command will use production credentials."
  API_TOKEN: op://DOMAIN/VAULT/ITEM/FIELD

With hooks, disclaimers cannot prompt for input. Lade withholds access and prints an approval code; review it, then run lade approve <code> or re-run the command with LADE_APPROVE=<code>.

Per-user values

"deploy .*":
  API_TOKEN:
    alice: op://DOMAIN/VAULT/ALICE_TOKEN/FIELD
    ci: vault://DOMAIN/MOUNT/ci-token/value
    .: op://DOMAIN/VAULT/DEFAULT_TOKEN/FIELD
lade user
lade user alice
lade user --reset

Networks

Network providers acquire temporary local forwards for the command lifecycle. Assign a URI to an environment variable for a dynamic local port, or to a number for a fixed local port.

"psql .*":
  DB_PORT: kubectl://k8s.example.com:6443/prod/default/service/postgres/5432
  1223: ssh://jump.example.com:22/db.internal/5432

Supported network providers:

Provider URI Query options
kubectl kubectl://<cluster-host>:<cluster-port>/<context-selector>/<namespace>/<kind>/<name>/<remote-port> local=HOST:PORT, pod-running-timeout=<duration>
kubefwd kubefwd://<cluster-host>:<cluster-port>/<context-selector>/<namespace>/<kind>/<name>/<service-port> local=HOST:PORT, domain=<domain>, selector=<selector>
tsh tsh://<proxy-host>:<proxy-port>/<kube-cluster>/<namespace>/<kind>/<name>/<remote-port> local=HOST:PORT
ssh ssh://<jump-host>:<jump-port>/<remote-host>/<remote-port> local=HOST:PORT

See examples/tape/lade.yml and examples/tape/network.txt for more examples.

In CI, OP_SERVICE_ACCOUNT_TOKEN is usually injected directly by the platform. If the token itself lives in another vault, add 1password_service_account to the . block. Lade resolves that URI first and uses it while resolving remaining op:// secrets.

"deploy .*":
  .:
    1password_service_account: vault://DOMAIN/MOUNT/KEY/FIELD
  API_TOKEN: op://DOMAIN/VAULT/ITEM/FIELD
