env-management

name	env-management
description	You need to add a new API key to the system, update an existing credential, check what secrets are configured for the org or a specific agent, onboard a new third-party tool that needs credentials, diagnose why an agent cannot access a service because a key appears missing, rotate a compromised or expired key, or restart affected agents after a credential change. This skill covers the full lifecycle of environment variables and secrets in cortextOS.

Environment Variable Management

cortextOS uses a 4-layer env hierarchy. Later layers override earlier ones:

1. Base shell (PATH, HOME, etc.)
2. CTX_* vars (set by agent-pty at session start)
3. orgs/{org}/.env  ← shared secrets, all agents in the org
4. orgs/{org}/agents/{agent}/.env  ← agent-specific secrets

Where Each Key Lives

Key type	File	Example
Shared API keys (multiple agents use)	orgs/{org}/.env	OPENAI_API_KEY, APIFY_TOKEN
Agent Telegram credentials	agents/{agent}/.env	BOT_TOKEN, CHAT_ID, ALLOWED_USER
Agent OAuth tokens	agents/{agent}/.env	CLAUDE_CODE_OAUTH_TOKEN

Rule: If more than one agent uses a key, it belongs in the org .env. If only one agent uses it, it belongs in that agent's .env.

ANTHROPIC_API_KEY is inherited from the shell that launched the daemon — never stored in any file.

---

Adding a New Shared Secret

# 1. Locate the org .env
ORG_ENV="$CTX_FRAMEWORK_ROOT/orgs/$CTX_ORG/.env"

# 2. Append the new key (never overwrite existing)
echo 'NEW_KEY=value' >> "$ORG_ENV"
chmod 600 "$ORG_ENV"

# 3. Restart all running agents so they pick it up
cortextos list-agents --format json | jq -r '.[].name' | while read agent; do
  cortextos bus hard-restart --agent "$agent" --reason "new shared secret added: NEW_KEY"
done

---

Adding an Agent-Specific Secret

# 1. Locate the agent .env
AGENT_ENV="$CTX_FRAMEWORK_ROOT/orgs/$CTX_ORG/agents/$CTX_AGENT_NAME/.env"

# 2. Append the key
echo 'MY_KEY=value' >> "$AGENT_ENV"
chmod 600 "$AGENT_ENV"

# 3. Restart THIS agent only
cortextos bus self-restart --reason "new agent secret added: MY_KEY"

---

Checking What Keys Are Configured

# Check org-level keys (names only — never print values)
grep -v '^#' "$CTX_FRAMEWORK_ROOT/orgs/$CTX_ORG/.env" | grep '=' | cut -d= -f1

# Check agent-level keys (names only)
grep -v '^#' "$CTX_FRAMEWORK_ROOT/orgs/$CTX_ORG/agents/$CTX_AGENT_NAME/.env" | grep '=' | cut -d= -f1

# Verify a key is set in current session
[[ -n "${SOME_KEY:-}" ]] && echo "SET" || echo "NOT SET"

---

Rotating a Secret

A key update without restarting the agent does nothing — the old value stays in the PTY environment until the process restarts.

Rotation Decision Tree

Is this a shared org-level key (OPENAI_API_KEY, APIFY_TOKEN, etc.)?
  → Update orgs/{org}/.env → hard-restart ALL agents

Is this an agent-specific key (BOT_TOKEN, CHAT_ID, OAuth token)?
  → Update agents/{agent}/.env → hard-restart THAT AGENT ONLY

Is this ANTHROPIC_API_KEY?
  → Update ~/.zshrc or ~/.bashrc → restart the daemon via PM2
  → Do NOT store in any .env file

Rotating a Shared Org Secret

ORG_ENV="$CTX_FRAMEWORK_ROOT/orgs/$CTX_ORG/.env"
# Update the value in the file (edit KEY_NAME line)

# Restart all agents in sequence (stagger to avoid gaps)
cortextos list-agents --format json | jq -r '.[].name' | while read agent; do
  echo "Restarting $agent..."
  cortextos bus send-message "$agent" high "hard-restart" "secret rotation: KEY_NAME"
  sleep 30
done

# Log the rotation
cortextos bus log-event action secret_rotated info \
  --meta "{\"key\":\"KEY_NAME\",\"scope\":\"org\",\"agent\":\"$CTX_AGENT_NAME\"}"

Rotating an Agent-Specific Secret

AGENT_ENV="$CTX_FRAMEWORK_ROOT/orgs/$CTX_ORG/agents/AGENT_NAME/.env"
# Update the value in the file
chmod 600 "$AGENT_ENV"

# Hard-restart that agent (not soft — PTY must rebuild env)
cortextos bus send-message AGENT_NAME high "hard-restart" "secret rotation: KEY_NAME"

cortextos bus log-event action secret_rotated info \
  --meta "{\"key\":\"KEY_NAME\",\"scope\":\"agent\",\"agent\":\"AGENT_NAME\"}"

Rotating a Bot Token (BOT_TOKEN)

1. Go to @BotFather → /mybots → select the bot → API Token → Revoke current token
2. Copy the new token
3. Update agents/{agent}/.env — replace BOT_TOKEN= value
4. Hard-restart the agent immediately (old token is already invalid)

---

Critical Rules

1. Never print secret values — log key names only, never values
2. Never commit .env files — they are in .gitignore by design
3. Always chmod 600 after writing any .env file
4. Never edit a running agent's .env without restarting — changes won't take effect until the PTY env is rebuilt
5. Never add BOT_TOKEN to org .env — each agent must have its own Telegram bot
6. ANTHROPIC_API_KEY lives only in the shell — do not add to any .env file
7. Always hard-restart after rotating — soft-restart preserves the PTY env which still has the old value
