Bitwarden

Bitwarden CLI — Secrets Management

Core Concept

Secrets are stored as Bitwarden Secure Notes with export KEY='value' lines in the notes field. One eval call loads them into the current shell. No files on disk. Secrets die with the session.

Shell Functions

All functions ship in lib/bw-functions.sh — source it in your shell profile. No copy-pasting, no dotfiles dependency.

Setup on a new machine

# 1. Install bw CLI
brew install bitwarden-cli    # macOS
sudo snap install bw          # Ubuntu
npm i -g @bitwarden/cli       # any OS

# 2. Install skill (choose one)
npx clawhub install bitwarden-bwe            # via ClawHub
# or: git clone https://github.com/stevengonsalvez/clawdbot /path/to/clawdbot

# 3. Source functions in your shell profile
echo 'source /path/to/skills/bitwarden-bwe/lib/bw-functions.sh' >> ~/.bashrc
source ~/.bashrc

# 4. Login + unlock
export BW_CLIENTID="user.xxxxx"
export BW_CLIENTSECRET="xxxxx"
bw login --apikey
bwss   # unlock (prompts for master password)

# 5. Verify
bwl    # list vault items

What's in lib/bw-functions.sh

Notes on bwe_safe: Guards against non-export lines being injected but does not sanitize values — a value containing $(cmd) or backticks would still execute during eval. If someone has write access to your Bitwarden vault, you have bigger problems. Use on shared org accounts as a defence-in-depth layer.

Workflow

Daily use

bwss                     # Unlock vault (once per terminal session)
bw sync                  # Pull latest from server (if secrets were updated in web vault)
bwe agent-fleet          # Load all agent secrets
echo $ANTHROPIC_API_KEY  # Verify — should be set

Creating / updating secrets

# From a .env file
bwc my-new-project .env

# From current shell
bwce snapshot-2026-03-03

# Update an existing note (delete + recreate)
bwdd old-note
bwc old-note .env.updated

# Or edit in web vault — notes field, one `export KEY='value'` per line

Org + Collection pattern (team/fleet use)

For sharing secrets with a machine account (e.g., GCP VM):

1. Create a Bitwarden Organization (free tier = 2 users)
2. Create a Collection in the org (e.g., popa-secrets)
3. Create a machine account — separate Bitwarden account, invited to org, assigned to the collection
4. Add Secure Notes to the collection with export KEY='value' format
5. On the target machine: install skill, source lib/bw-functions.sh, login with machine account API key, bwss, bwe <note>

The machine account sees ONLY items in its assigned collection. Revoke access = remove from org. One click.

Creating items in a collection (programmatic)

COLLECTION_ID="<collection-uuid>"
ORG_ID="<org-uuid>"
NOTES=$(cat .env | awk '{print "export " $0}')

bw get template item | jq \
  --arg notes "$NOTES" \
  --arg name "my-item" \
  --arg orgId "$ORG_ID" \
  --argjson colIds "[\"$COLLECTION_ID\"]" \
  '.type = 2 | .secureNote.type = 0 | .notes = $notes | .name = $name | .organizationId = $orgId | .collectionIds = $colIds' \
  | bw encode | bw create item

Listing collections and orgs

bw list organizations | jq '.[] | {id, name}'
bw list collections | jq '.[] | {id, name}'
bw list items --collectionid <id> | jq '.[] | .name'

Secure Note Format

Each Secure Note's notes field contains one secret per line:

export ANTHROPIC_API_KEY='sk-ant-...'
export OPENAI_API_KEY='sk-proj-...'
export DISCORD_TOKEN='MTQ3...'

Rules:

• One export KEY='value' per line
• Always single-quote values. Unquoted values containing |, !, #, $, backticks, or other shell metacharacters will break or execute during eval. Single quotes prevent this.
• No comments, no blank lines (they get eval'd)
• Keys should be UPPER_SNAKE_CASE
• If a value itself contains a single quote, use ''' to escape it: export KEY='value'''s edge case'
• Never put shell commands in values

Guardrails

• Never paste secrets into chat, logs, or code. Use bwe to load into memory only.
• Never write secrets to disk unless absolutely necessary (and chmod 600 if you must).
• Prefer bwe over ~/.secrets/ files. Secrets in memory > secrets on disk.
• Use bwe_safe on shared/org accounts. Defence in depth against note tampering.
• bwss once per terminal session. The session token persists until the shell exits.
• Sync before pulling: bw sync if you've recently updated secrets in the web vault.
• Lock when done: bw lock to clear the session token.

Tmux Considerations

If using bw inside tmux (common for agents), the BW_SESSION env var must be available in the tmux pane. Either:

• Run bwss inside the tmux pane, or
• Export BW_SESSION before creating the tmux session

# Option 1: unlock inside tmux (preferred — interactive, no password in process list)
tmux new-session -d -s work
tmux send-keys -t work 'bwss' Enter
# ... wait for unlock prompt, enter master password ...
tmux send-keys -t work 'bwe agent-fleet' Enter

# Option 2: pass session token via env var (non-interactive)
# ⚠️ Never pass the master password as a CLI argument — it's visible in `ps aux`.
# Use --passwordenv instead:
read -s BW_MASTER_PASSWORD && export BW_MASTER_PASSWORD
export BW_SESSION=$(bw unlock --passwordenv BW_MASTER_PASSWORD --raw)
unset BW_MASTER_PASSWORD
tmux new-session -d -s work -e "BW_SESSION=$BW_SESSION"
tmux send-keys -t work 'bwe agent-fleet' Enter
