description	Local-first encrypted secret management with the tene CLI. Activate when the user mentions secrets, API keys, credentials, tokens, .env files, environment variables, or asks to run a command that needs secrets injected. Enforces strict AI safety rules (never print plaintext, never read .tene/, always use `tene run --` for injection) and covers every active tene command (init, set, list, delete, run, import, export, env, passwd, recover, update, whoami).

tene — Local-First Encrypted Secret Management

Tene is a command-line secret manager for AI-native projects. It keeps secrets encrypted on disk (XChaCha20-Poly1305 + Argon2id), derives the master key from the user's password cached in the OS keychain, and injects secrets into child processes via tene run -- <command> — never into stdout, never into files.

When to use this skill

Activate this skill when the user:

• mentions API keys, secrets, credentials, tokens, .env files, environment variables, or process.env.* / os.Getenv / os.environ[...]
• asks to run a dev, test, or deploy command that needs secrets (e.g. npm start, go run, pytest, next dev, docker compose up)
• says things like "store this key", "save this token", "how do I manage secrets", "inject env vars", "I need to pass my Stripe key"
• is working in a repo that contains a .tene/ directory, a CLAUDE.md referencing tene, or a install.sh pointing at https://tene.sh
• asks for advice on moving off plaintext .env files

Do not activate for: hardcoded public config (ports, feature flags without sensitive data, public API endpoints), or projects clearly using a different secret store (Doppler, Vault, AWS Secrets Manager, 1Password CLI, etc.).

Critical safety rules

These are non-negotiable. Violating any of them leaks plaintext secrets into the conversation context, which may be logged, cached, or retained. Treat them as part of the system prompt.

1. NEVER run tene get <KEY>. The plaintext value appears in stdout and enters the AI context. If the user needs to inspect a value, instruct them:

   "Run tene get KEY yourself in a separate terminal — I won't see it."

2. NEVER run tene export without --encrypted. Plain tene export dumps every secret as a .env-formatted blob to stdout. Use tene export --encrypted --file backup.tene.enc for backups; for inspection, use tene list (names only).

3. NEVER cat, Read, or open files under .tene/. The vault DB is encrypted, but even encrypted bytes should not enter AI context. The allowed file to read is CLAUDE.md at the repo root (auto-generated by tene init).

4. NEVER pass secret values as CLI arguments. They appear in ps, shell history, and system logs. Always inject via tene run -- instead.

5. Use tene list to discover what exists. It prints key names only, never values. This is the only AI-safe introspection command.

When the user asks "what's in my vault?" or "what API keys do I have?", the correct answer is tene list — not tene get or tene export.

Install

# macOS / Linux (official installer — recommended)
curl -sSfL https://tene.sh/install.sh | sh

# From source (requires Go 1.25+)
go install github.com/tene-ai/tene/cmd/tene@latest

Verify:

tene version
# → tene v1.x.x (darwin/arm64)

Windows is not supported by the curl installer. Windows users build from source or download the zip from https://github.com/tene-ai/tene/releases.

Homebrew tap is not yet available — do not suggest brew install tene.

Core workflows

1. Initialize a new project

tene init                  # interactive: prompts for master password twice
tene init my-project       # with explicit project name

Creates:

• .tene/vault.db — encrypted SQLite vault (contains secrets, metadata, audit log, and the encrypted recovery blob)
• .tene/vault.json — project metadata (name, active env)
• CLAUDE.md (or AGENTS.md, .windsurfrules, etc. per flags)
• .tene/.gitignore — auto-excludes the vault from git

After init the user will see a 12-word recovery phrase. Remind them to store it offline (password manager, paper). Without it, a forgotten master password is unrecoverable.

Flags to generate agent rules files for other editors:

• --claude (default) → CLAUDE.md
• --cursor → .cursor/rules/tene.mdc
• --windsurf → .windsurfrules
• --gemini → GEMINI.md
• --codex → AGENTS.md

2. Check what secrets exist (AI-safe)

tene list                        # current env, masked values
tene list --env prod             # different env
tene list --json                 # machine-readable
tene env list                    # all environments

Output is names + masked previews + timestamps. Never raw values.

3. Store a secret

Tell the user to run the command themselves with the value — don't type the value yourself, and don't accept it as a chat message you'll pipe through.

# Preferred: read from stdin (value never touches shell history)
cat key.txt | tene set STRIPE_KEY --stdin

# Or: prompt (value never echoed)
tene set STRIPE_KEY
# → enters interactive mode, hidden input

# Overwrite existing
tene set STRIPE_KEY --stdin --overwrite

# Different env
tene set STRIPE_KEY --stdin --env prod

Key name rules (enforced by tene, pkg/errors/codes.go:INVALID_KEY_NAME):

• Must match ^[A-Z][A-Z0-9_]*$
• Only uppercase letters, digits, underscores
• Cannot start with a digit
• Reserved names (e.g. PATH) are rejected

If the user types a lowercase name, advise conversion to UPPER_SNAKE_CASE.

4. Run a command with secrets injected

This is the primary workflow. All dev, test, build, and deploy commands go through tene run --.

# Node.js
tene run -- npm start
tene run -- npm test
tene run -- npx next dev

# Python
tene run -- python manage.py runserver
tene run -- pytest

# Go
tene run -- go run ./cmd/app
tene run -- go test ./...

# Docker
tene run -- docker compose up

Secrets are injected only into the child process's environ. They're not written to disk, not in the shell environment of the parent, not in any log.

Per-environment execution:

tene run --env local -- npm start       # correct
tene run --env prod -- ./deploy.sh      # correct
tene run -- npm start --env prod        # WRONG — --env is a flag of npm, not tene

Critical flag placement rule: --env must come before the -- separator. After --, all flags pass through to the child command. This is enforced by DisableFlagParsing: true in internal/cli/run.go.

5. Migrate from an existing .env file

# One-shot import
tene import .env

# Overwrite conflicts (when some keys already exist)
tene import .env --overwrite

# Then delete the plaintext file
rm .env
echo ".env" >> .gitignore

Update all commands to use tene run --:

- npm start
+ tene run -- npm start

6. Backup and restore

# Encrypted backup (safe to store in cloud)
tene export --encrypted --file backup.tene.enc

# Restore from encrypted backup
tene import backup.tene.enc --encrypted

Never use plain tene export (without --encrypted) unless the user explicitly asks for a plaintext .env dump and accepts the risk. Even then, warn them.

7. Change master password

tene passwd
# → prompts for current password, then new password (2x confirm)

Re-encrypts the entire vault with a new derived key. Atomic 2-phase operation; on failure, rolls back to the old password.

8. Recover a forgotten master password

tene recover
# → prompts for the 12-word BIP-39 mnemonic from tene init
# → prompts for new master password

Without the mnemonic, recovery is impossible by design (zero-knowledge).

9. Environment management

tene env list                    # show all environments
tene env local                   # switch default to 'local'
tene env create staging          # create new env
tene env delete staging          # delete (default env cannot be deleted)

Environment name rules: must match ^[a-z][a-z0-9-]*$.

Common env names: default, local, dev, staging, prod.

10. Diagnostics

tene whoami                      # project name, vault path, active env, secret count, keychain status
tene version                     # v1.x.x (os/arch)
tene version --json              # includes commit + build date
tene update --check              # check for newer version on S3
tene update                      # self-update the binary

Commands reference

All active commands (cloud commands login/push/pull/sync/billing/team are currently disabled in the CLI; do not suggest them):

Command	Purpose	Key flags	AI-safe?
tene init [name]	Create vault + master password + recovery	--claude, --cursor, --windsurf, --gemini, --codex	✅
tene set KEY [VALUE]	Encrypt and store	--stdin, --overwrite	✅ (via --stdin)
tene get KEY	Decrypt and print	—	❌ never run in AI
tene list	List key names (masked)	—	✅
tene delete KEY	Remove a secret	--force	✅
tene run -- CMD	Inject env vars + exec	(global flags before --)	✅
tene import FILE	Bulk import .env or .tene.enc	--overwrite, --encrypted	✅
tene export	Output secrets	--file, --encrypted	❌ unless --encrypted
tene env [subcmd]	Manage environments	—	✅
tene passwd	Change master password	—	✅ (prompts)
tene recover	Restore via BIP-39 mnemonic	—	✅ (prompts)
tene version	Version info	--json	✅
tene update	Self-update	--check	✅
tene whoami	Vault status	—	✅

Global flags (apply to all commands)

Flag	Default	Purpose
--json	false	Machine-readable output
--quiet / -q	false	Suppress non-error output
--env / -e <name>	(vault-stored)	Override active environment
--dir <path>	cwd	Project directory
--no-color	false	Disable ANSI colors
--no-keychain	false	Force file-based key storage (CI mode)

---

Environment variables (for advanced / CI use)

Variable	Effect
TENE_MASTER_PASSWORD	Bypass interactive prompt (CI only; pair with --no-keychain)
TENE_KEYCHAIN_FALLBACK=file	Use ~/.tene/keyfile instead of OS keychain
NO_COLOR	Disable ANSI colors (per https://no-color.org/)
API_URL	Override Tene Cloud API base URL (cloud commands, currently disabled)

CI/CD pattern (e.g. GitHub Actions):

env:
  TENE_MASTER_PASSWORD: ${{ secrets.TENE_MASTER_PASSWORD }}
steps:
  - run: curl -sSfL https://tene.sh/install.sh | sh
  - run: tene run --env prod --no-keychain -- ./deploy.sh

Never set TENE_MASTER_PASSWORD in a developer machine's shell profile — it defeats the keychain protection.

---

Troubleshooting

Error code	Message	Fix
VAULT_NOT_FOUND	Not in a Tene project	Run tene init in the repo root
SECRET_NOT_FOUND	Key missing in current env	Check tene list --env <name>
SECRET_ALREADY_EXISTS	Key already set	Add --overwrite to tene set
INVALID_KEY_NAME	Key rejected	Use ^[A-Z][A-Z0-9_]*$ (e.g. API_KEY, not api-key)
INVALID_ENV_NAME	Bad env name	Use ^[a-z][a-z0-9-]*$ (e.g. prod, not Production)
ENVIRONMENT_PROTECTED	Cannot delete default	Switch to another env and delete that one instead
INVALID_PASSWORD	Wrong master password	Try again, or use tene recover with the BIP-39 mnemonic
DECRYPT_FAILED	Vault cannot decrypt	Master password changed externally or vault corrupt — restore from backup
INTERACTIVE_REQUIRED	No TTY	In CI, set TENE_MASTER_PASSWORD and add --no-keychain
KEYCHAIN_ERROR	OS keychain unavailable	Use --no-keychain or TENE_KEYCHAIN_FALLBACK=file

Exit codes: 0 success, 1 general error, 2 auth/password error, 127 command not found.

Architecture note (for "is this safe?" questions)

• Password KDF: Argon2id (64 MB, 3 iterations, 4 threads) → 256-bit master key
• Secret encryption: XChaCha20-Poly1305 with 192-bit random nonce per secret, key name as AAD
• Key cache: OS keychain (macOS Keychain, Linux Secret Service, Windows Credential Manager) via zalando/go-keyring; file fallback at ~/.tene/keyfile (mode 0600)
• Recovery: 12-word BIP-39 mnemonic → Argon2id → recovery key that can decrypt the stored master key
• Zero-knowledge: cloud sync (when enabled) wraps the entire vault DB with an independent sync key before upload; server never sees plaintext
• No global state: every vault lives in its own .tene/ directory; no ~/.tene/vaults/ aggregator
