Secrets Management Skill

Manage credentials securely via Bitwarden. This vault does NOT store credentials - all secrets are kept in Bitwarden and accessed on-demand.

Configuration

By default, secrets are stored in a Bitwarden folder called "Obsidian Vault". You can customise this by setting BITWARDEN_FOLDER in your environment or updating the folder name in the commands below.

Commands

Implementation

/secrets status

Check Bitwarden CLI installation and session status:

# Check if Bitwarden CLI is installed
if ! command -v bw &> /dev/null; then
    echo "Bitwarden CLI not installed"
    echo "   Install with: brew install bitwarden-cli"
    exit 1
fi

# Check login and lock status
STATUS=$(bw status)
echo "$STATUS" | jq -r '"Status: \(.status)"'

Report to user:

• •CLI installed: yes/no
• •Logged in: yes/no
• •Vault: locked/unlocked
• •If not set up, suggest /secrets setup

/secrets get <name>

1. •

   Ensure Bitwarden is unlocked:

   bash

   BW_SESSION=$(bw unlock --raw 2>/dev/null)
   if [ -z "$BW_SESSION" ]; then
       echo "Please unlock Bitwarden first: bw unlock"
       exit 1
   fi
   

2. •

   Retrieve the item:

   bash

   ITEM=$(bw get item "$SECRET_NAME" --session "$BW_SESSION" 2>/dev/null)
   if [ -z "$ITEM" ]; then
       echo "Secret '$SECRET_NAME' not found"
       exit 1
   fi
   

3. •

   Extract based on type:

   bash

   TYPE=$(echo "$ITEM" | jq -r '.type')
   if [ "$TYPE" = "2" ]; then
       # Secure Note - return notes field
       echo "$ITEM" | jq -r '.notes'
   else
       # Login - offer username/password
       echo "Username: $(echo "$ITEM" | jq -r '.login.username')"
       echo "Password: [hidden - use --show-password to display]"
   fi
   

CRITICAL: Never store retrieved secrets in files or conversation history. Display once and advise user to copy immediately.

/secrets list

# Set your Bitwarden folder name (customise as needed)
FOLDER_NAME="${BITWARDEN_FOLDER:-Obsidian Vault}"

BW_SESSION=$(bw unlock --raw)
FOLDER_ID=$(bw get folder "$FOLDER_NAME" --session "$BW_SESSION" | jq -r '.id')
bw list items --folderid "$FOLDER_ID" --session "$BW_SESSION" | jq -r '.[] | "\(.name) (\(if .type == 2 then "note" else "login" end))"'

Display as formatted table with Name and Type columns.

/secrets env

Generate environment variable export commands:

# Set your Bitwarden folder name (customise as needed)
FOLDER_NAME="${BITWARDEN_FOLDER:-Obsidian Vault}"

BW_SESSION=$(bw unlock --raw)
FOLDER_ID=$(bw get folder "$FOLDER_NAME" --session "$BW_SESSION" | jq -r '.id')

# Get all Secure Notes in the folder
bw list items --folderid "$FOLDER_ID" --session "$BW_SESSION" | \
  jq -r '.[] | select(.type == 2) |
    "export " + (.name | gsub(" "; "_") | gsub("-"; "_") | ascii_upcase) + "=\"" + (.notes | gsub("\n"; "\\n") | gsub("\""; "\\\"")) + "\""'

Output format:

# Bitwarden secrets for your vault
# Run: eval "$(/secrets env)" or copy/paste below

export ANTHROPIC_API_KEY="<your-key>"  # pragma: allowlist secret
export OPENAI_API_KEY="<your-key>"     # pragma: allowlist secret
export GITHUB_PAT="<your-token>"       # pragma: allowlist secret

# These are session-only - not persisted to disk

/secrets setup

Guide the user through setup:

1. •

   Check/Install CLI:

   bash

   brew install bitwarden-cli
   

2. •

   Login:

   bash

   bw login
   # Or for SSO: bw login --sso
   

3. •

   Unlock vault:

   bash

   export BW_SESSION=$(bw unlock --raw)
   

4. •

   Verify access:

   bash

   bw list folders --session $BW_SESSION
   

5. •

   Create your vault folder (if it doesn't exist):

   bash

   # Create a folder for your vault secrets
   bw create folder '{"name":"Obsidian Vault"}' --session $BW_SESSION
   

6. •

   Import secrets (if migrating from Atomic Notes):

   bash

   bw import bitwardencsv bitwarden-import.csv
   

7. •

   Add shell alias (optional):

   bash

   echo 'alias bw-unlock="export BW_SESSION=\$(bw unlock --raw)"' >> ~/.zshrc
   

Environment Variable Naming Convention

Custom mappings can be added to .claude/config.local.json:

{
  "secrets": {
    "folderName": "My Custom Folder",
    "envMapping": {
      "My Custom Item": "CUSTOM_VAR"
    }
  }
}

Security Rules

1. •Never write secrets to files in this vault
2. •Never include secrets in commit messages or code comments
3. •Never display secrets in full unless explicitly requested
4. •Session keys are temporary - they expire and must be refreshed
5. •Delete CSV immediately after Bitwarden import
6. •Rotate credentials that were ever in git history

Integration with Scripts

Scripts should read from environment variables, not files:

Python:

import os

api_key = os.environ.get('ANTHROPIC_API_KEY')
if not api_key:
    raise ValueError("ANTHROPIC_API_KEY not set. Run: /secrets env")

JavaScript/Node.js:

const apiKey = process.env.ANTHROPIC_API_KEY;
if (!apiKey) {
  throw new Error("ANTHROPIC_API_KEY not set. Run: /secrets env");
}

Bash:

if [ -z "$ANTHROPIC_API_KEY" ]; then
    echo "ANTHROPIC_API_KEY not set. Run: /secrets env"
    exit 1
fi

Quick Reference

# One-time setup
brew install bitwarden-cli
bw login

# Each session
export BW_SESSION=$(bw unlock --raw)

# Get a secret
bw get item "Anthropic API Key" --session $BW_SESSION | jq -r '.notes'

# List all vault secrets (update folder name as needed)
FOLDER_NAME="Obsidian Vault"
bw list items --folderid $(bw get folder "$FOLDER_NAME" --session $BW_SESSION | jq -r '.id') --session $BW_SESSION | jq -r '.[].name'
