tene-cli

tene-cli is a skill for Claude Code, Codex from tene-ai/tene. It costs 103 tokens per session (3,600 once invoked), scanned C, original, MIT.

A command-line tool for storing sensitive values such as API keys, passwords, tokens, and environment variables in encrypted local files. It can provide those values to a program when the program runs without printing them or writing them into other files.

In plain words
What is it for?
Use it to save and inject credentials when running development, testing, deployment, or other commands that need private configuration.
Why use it?
It removes the need to keep secrets in plain-text .env files or expose them in terminal output and source files.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade C, and why

tene-cli scanned grade C with 2 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

How it starts

The opening of the file, as written. The whole thing — 382 lines — stays where its author put it; the contents beside it link to each section on GitHub.

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).

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

tene-cli is a skill published in the GitHub repository tene-ai/tene (15 stars, last pushed 2mo ago), licensed MIT. It adds 103 tokens to every session and 3,600 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it C with 2 findings (downloads and executes remote code, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
