_ensure-vault

_ensure-vault is a skill for Claude Code from flavien-ia/hypervibe-harness. It costs 83 tokens per session (899 once invoked), scanned A, original, Apache-2.0.

An internal preflight check that makes sure the Bitwarden password vault is unlocked before another skill reads a stored key.

In plain words
What is it for?
It supports skills that need credentials for services such as Cloudflare, Neon, Resend, Brevo, Hostinger, or Anthropic.
Why use it?
It prevents a later key lookup from failing because the vault is locked, and opens the unlock request at the start when needed.

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 A, and why

_ensure-vault scanned grade A with 0 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 11d 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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

_ensure-vault - "the vault is open" preflight

Communication

  • Detect the user's language from the conversation (the user's own messages, anywhere in the session - not just this invocation: a bare slash command like /bootstrap carries no language signal by itself). If nothing in the conversation gives a signal, fall back to the OS locale (node -e "console.log(Intl.DateTimeFormat().resolvedOptions().locale)") before defaulting to English. ALWAYS reply in that language for every user-facing message: questions, progress, confirmations, summaries, errors - including any example text quoted in this skill, which is illustrative and must be translated, never sent verbatim.
  • Use plain, non-technical business language. Never expose internal script names (*.mjs) or jargon; describe actions in human terms.
  • When generating user-facing content for the scaffolded project (UI labels, emails, copy), write it in the user's language too.
  • Show progress as a short natural-language checklist (in-progress and done states).

To run at the start of any skill that will read a key from the vault. Goal: open the unlock window once up-front rather than letting a key-read silently fail later (notably the case of scripts that go through readUserEnv, which returns null without flagging "locked").

Since the vault stays open for 12h, this preflight only triggers a window once per day, on first need.

Snippet (run as-is)

VAULT="${CLAUDE_SKILL_DIR}/../../scripts/vault/vault.mjs"
ST=$(node "$VAULT" status 2>/dev/null)
echo "vault:$ST"

Depending on ST:

  • unlocked → vault ready, continue the skill normally.
  • locked or expired → notify the user in the chat, then open the unlock window (blocking), then re-check:

    "Your key vault is closed - a window will open for your master password (once per day)."

    node "${CLAUDE_SKILL_DIR}/../../scripts/vault/launch.mjs" unlock --lang <LANG>
    node "$VAULT" status   # should return "unlocked"
    
    The window asks for the master password up to 3 times before giving up, so a typo is fixed on the spot. If it still exits non-zero, the three attempts were wrong: say so in the chat and ask the user before opening another window. Never reopen one on your own - that is how a mistyped password turns into an endless chain of windows.
  • Empty output / error (no bw, no account connected → vault never configured) → the vault does not exist yet: delegate to _add-keyring (installs bw + creates the account + login + unlock), then re-check. If the user declines to set up the vault, flag it and stop cleanly (the skill will not be able to retrieve its keys).

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.
