secrets-inject

Secrets Inject ⚠️ (HIGH PRIVILEGE)

This skill deliberately takes encrypted secrets and turns them into executable shell commands containing plaintext secrets. It exists as a separate, clearly-labeled skill so the core secrets-manager can stay a pure, clean store. Only install/use this if you actually need to inject secrets into a command.

⚠️ Why this is dangerous (read before use)

• It decrypts secrets and writes them into a plaintext temp shell script (/tmp/secrets-inject-*.sh, mode 0600).
• Anyone who can read that temp file (same user, backups, forensic images, exfiltration) gets the plaintext secrets.
• Printing to stdout (--inject-stdout) puts plaintext secrets into shell history, logs, journald, CI output, and terminal scrollback.
• This is the canonical "secret exfiltration path" — treat it with the same care you'd give cat .master-key.

When you might need it

You have a secret in secrets-manager and must pass it to a command that needs it inline (e.g. curl -H "Authorization: Bearer {{api_key}}").

Quick Start

# 1) Store the secret first (separate skill)
node skills/secrets-manager/secrets-manager.js --store api_key sk-abc123

# 2) Inject into a command → writes a temp script, prints its path
node skills/secrets-inject/secrets-inject.js --inject "curl -H 'Authorization: Bearer {{api_key}}' https://api.example.com/v1"
# Output: [secrets-inject] ✅ Injected 1 secret(s) into: /tmp/secrets-inject-12345-1.sh
#         [secrets-inject]    Run with:  sh /tmp/secrets-inject-12345-1.sh

# 3) Run it, then CLEAN UP
sh /tmp/secrets-inject-12345-1.sh
node skills/secrets-inject/secrets-inject.js --cleanup-tmp

Print to stdout (DANGEROUS — requires explicit confirmation)

node skills/secrets-inject/secrets-inject.js --inject-stdout --confirm-expose "echo {{api_key}}"
# Will print the resolved command with the plaintext secret.

The skill refuses to print to stdout without --confirm-expose.

Cleanup

Temp injection files are tracked in memory/secrets/.tmp-injections.json and removed by --cleanup-tmp. They are NOT auto-removed — delete them after use. An undeleted temp file is plaintext-on-disk exposure.

Security Notes

• Temp scripts are chmod 0600 but are still plaintext on disk — the only protection is file permissions and your diligence in deleting them.
• Prefer secrets-manager --get --raw > /tmp/k && chmod 600 /tmp/k and pass the file path to a command instead of inline injection when possible.
• Never run this on a shared host, container, or CI runner you don't fully trust.
• This skill does NOT store secrets — it only reads the secrets-manager store.

What this skill does NOT do

• Does NOT store secrets (that's secrets-manager).
• Does NOT transmit secrets anywhere (it only substitutes them locally).
• Does NOT auto-clean temp files (you must run --cleanup-tmp).
