│  Action: Safely write encrypted secrets via sops            │
│  Output: Updated secrets file + redacted summary            │
╰─────────────────────────────────────────────────────────────╯

When to Use

• "add secrets via sops"
• "update encrypted secrets"
• "sops set"
• "store credentials in sops"
• "put this secret in secrets.yaml"
• "add new api key in sops"

Inputs to Collect

• Target secrets file path (default: nixpkgs/secrets/secrets.yaml)
• Age key file path (default: ~/.config/sops/age/keys.txt)
• List of secrets to update (multiple allowed):
  • Key path (slash-separated, e.g., fpl/email)
  • Secret value (never echo back)
• Confirm yolo mode (apply all updates in one run without extra prompts)

Workflow / How to Run

1. Confirm defaults

   • Secrets file: nixpkgs/secrets/secrets.yaml
   • Age key file: ~/.config/sops/age/keys.txt

2. Validate prerequisites

   • Verify the secrets file exists.
   • Verify the age key file exists.
   • Set SOPS_AGE_KEY_FILE before running sops.

3. Convert key paths to JSON indices

   • fpl/email → ["fpl"]["email"]
   • aws/credentials → ["aws"]["credentials"]

4. Apply updates (yolo mode)

   • Use nix run nixpkgs#sops -- set --value-stdin for each secret.
   • Always JSON-encode values before passing to sops.
   • Run multiple updates in one session.

Example (multi-secret, safe stdin + JSON encoding):

set -euo pipefail
export SOPS_AGE_KEY_FILE="$HOME/.config/sops/age/keys.txt"
secrets_file="nixpkgs/secrets/secrets.yaml"

# Repeat per secret (no echo; JSON-encode via python)
read -s FPL_EMAIL
printf '%s' "$FPL_EMAIL" | python3 - <<'PY' | nix run nixpkgs#sops -- set --value-stdin "$secrets_file" '["fpl"]["email"]'
import json, sys
print(json.dumps(sys.stdin.read()))
PY

read -s FPL_PASSWORD
printf '%s' "$FPL_PASSWORD" | python3 - <<'PY' | nix run nixpkgs#sops -- set --value-stdin "$secrets_file" '["fpl"]["password"]'
import json, sys
print(json.dumps(sys.stdin.read()))
PY

5. Report results (redacted)
   • Summarize only the keys updated and the target file path.
   • Do not print or log secret values.

Output Format

• Confirmation that the secrets file was updated.
• List of updated keys (paths only, no values).
• Any errors encountered (redact sensitive data).

Safety Rules

• Never echo or log secret values.
• Never print decrypted files.
• Always use --value-stdin and JSON encoding.
• Do not store secrets in files, commits, or shell history.
• Stop immediately if sops cannot decrypt the file (missing age key).

Success Criteria

• Requested keys are updated in nixpkgs/secrets/secrets.yaml.
• No secret values are exposed in output or logs.
• sops exits successfully for every update.
