Security Audit

Security Audit

Automated self-assessment of the AI Harness security posture.

Check Modules

Parse $ARGUMENTS to determine scope. Default is full (all checks).

Credential Safety (credentials or full)

1. OAuth token expiry: Query oauth_tokens table — check if any expires_at is within 7 days or already expired
2. Encryption key present: Check if OAUTH_ENCRYPTION_KEY is set in .env (don't print the value, just confirm presence/absence)
3. Refresh token encryption: Query a token row — check if refresh_token field looks encrypted (contains : separators for iv:tag:ciphertext format) vs plaintext
4. .env file permissions: Check bridges/discord/.env has restrictive permissions (should be 600 or 640, not world-readable)
5. No secrets in logs: Grep heartbeat log files for common secret patterns (API keys, tokens, passwords): grep -ril "sk-\|Bearer \|password=" heartbeat-tasks/logs/ 2>/dev/null

Report: token status, encryption status, file permissions, any leaked secrets in logs.

Git Hygiene (git or full)

1. No .env committed: git ls-files | grep -i '\.env' — should return nothing
2. No credentials in tracked files: git ls-files | xargs grep -l "sk-\|PRIVATE KEY\|password\s*=" 2>/dev/null — should return nothing
3. Gitignore coverage: Check that .env, harness.db, *.state.json, .bot.pid, vault-embeddings.json are in .gitignore
4. No large binaries tracked: git ls-files | xargs -I{} sh -c 'test -f "{}" && wc -c < "{}"' 2>/dev/null | sort -rn | head -5 — flag files over 1MB
5. Uncommitted sensitive changes: Check git diff --name-only for any .env, credential, or key files

Report: pass/fail for each check with file paths if issues found.

Heartbeat Health (heartbeat or full)

1. All configs have plists: Compare heartbeat-tasks/*.json (excluding .state.json, .example, projects.json) against ~/Library/LaunchAgents/com.aiharness.heartbeat.*.plist — flag any missing
2. All plists loaded: Check launchctl list | grep com.aiharness — flag any with non-zero exit codes
3. Failure counts: Read all .state.json files — flag any with consecutive_failures > 0
4. Stale tasks: Flag any task whose last_run is more than 3x its schedule interval ago
5. Auto-paused tasks: Check all config JSONs for "enabled": false — flag with reason

Report: task-by-task status table.

Configuration Drift (config or full)

1. Agent tool restrictions match docs: Read bridges/discord/agent-loader.ts and verify all agents listed in .claude/agents/ have corresponding restriction entries (or are explicitly unrestricted)
2. MCP servers registered: Check ~/.claude/Config/mcp-config.json — verify vault, harness, projects, outlook, linkedin servers are registered
3. Global guardrails intact: Read task-runner.ts for GLOBAL_DISALLOWED_TOOLS — verify rm -rf, force push, DROP, DELETE FROM, kill -9 are all blocked
4. Channel configs consistent: Query channel_configs table — verify course channels have education agent, project channels have valid agents
5. PID file stale: Check .bot.pid — is the PID actually alive?

Report: pass/fail for each check.

Output Format

=== AI Harness Security Audit ===

Credentials:
  OAuth tokens:      OK (2 tokens, nearest expiry: 14 days)
  Encryption key:    OK (present in .env)
  Token encryption:  OK (iv:tag:ciphertext format)
  .env permissions:  OK (640)
  Secrets in logs:   OK (none found)

Git:
  .env not tracked:  OK
  No credentials:    OK
  Gitignore:         OK (5/5 patterns present)
  Large files:       OK (none over 1MB)

Heartbeat:
  Plists present:    OK (21/21)
  All loaded:        OK (21/21, exit 0)
  Failures:          OK (0 tasks with failures)
  Stale tasks:       WARN (daily-digest last ran 36h ago)

Config:
  Agent restrictions: OK (9 agents, 4 restricted)
  MCP servers:        OK (5/5 registered)
  Global guardrails:  OK (6 rules intact)
  Channel configs:    OK (4 course channels → education)
  PID file:           OK (PID 12345 alive)

Overall: HEALTHY (1 warning)

For issues, list each with severity (CRITICAL/WARN/INFO) and suggested fix.
