Lightweight detection techniques that work without a SIEM. Covers fake admin paths, decoy .env files, canary tokens, fake API keys planted in JS bundles, and tarpits that slow automated scanners. Invoke when public services see constant automated probing, when complementing fail2ban and WAF rules, or when high-signal detection is needed on a small budget.

Harden a PostgreSQL deployment whether managed or self-hosted. Covers pg_hba network and authentication rules, role separation (read-only, read-write, migration), row-level security for multi-tenant data, TLS configuration, backup encryption, and pg_audit logging. Invoke when provisioning a new Postgres, before opening it to a new app, or when reviewing a multi-tenant schema for isolation gaps.

Run a structured response to a suspected web or server compromise. Follows SANS PICERL — Preparation, Identification, Containment, Eradication, Recovery, Lessons Learned — and includes a post-mortem template. Invoke when a site is defaced, when malware or webshells appear, when admin accounts arrive unannounced, or when a provider sends an abuse notice.

Recognize the recurring security failure modes of LLM coding agents — Claude Code, Copilot, Cursor, Windsurf, and similar. Covers bulk operations without per-item review, safety-guard bypass as friction removal, acting on indirect injection, secrets in logs and commits, slopsquatting, outdated training patterns, sycophancy on insecure proposals, and silent error swallowing. Invoke when reviewing L

Apply the OWASP API Security Top 10 to REST and GraphQL endpoints. Covers broken object-level authorization (BOLA), mass assignment, excessive data exposure, unrestricted resource consumption, SSRF, broken function-level authorization, and GraphQL depth and complexity limits. Invoke when designing a new API, reviewing one before scaling, or after API abuse (scraping, account takeover).

Audit an inherited or unfamiliar codebase systematically rather than ad-hoc. Covers scope discipline, day-0 triage, SAST and SCA tool recipes (semgrep, CodeQL, gitleaks, trivy), OWASP Top 10 mapped to grep patterns, auth-surface walkthrough, and writing reports that drive remediation. Invoke when inheriting a codebase, accepting an audit engagement, or reviewing AI-generated code before shipping.

Find, rotate, and prevent leaked credentials across repositories and disk. Covers leak detection with gitleaks and trufflehog, rotation order (the leaked secret first, then outward), git history purge with git-filter-repo, and prevention via pre-commit scanning. Invoke when a secret was committed to git, when a private repo went public, or as periodic audit.

Audits your Cowork setup across five categories, scores each one, and gives you a prioritized improvement plan. For reviewing how well you are using Cowork, when optimizing your workspace configuration, or during a quarterly productivity review. Use when the user says "health check", "am I using cowork right", "optimize my setup", "cowork audit", "what am I missing", "is my setup good", or "how do

Verify and process Stripe webhooks safely against the real-world failure modes. Covers signature verification against the raw body, idempotency keys, replay protection, event-type allowlists, the partial-refund and dual-currency traps, and re-fetching authoritative state from Stripe for real-money actions. Invoke when wiring webhooks for the first time, when adding a new event type, or after a pay

Detect and contain WordPress compromises, then harden the install against re-entry. Covers webshell detection across the Sid Gifari, WSO, FilesMan, b374k and c99 families, backdoored mu-plugins, malicious admin accounts, and shared-hosting lateral-movement defense. Invoke when a WordPress site shows unexpected files, suspicious admin accounts, defaced pages, or when hardening a fresh install on sh

Design backups that actually work when they are needed. Covers RPO and RTO definition, the 3-2-1 rule, encryption before leaving the host, ransomware-resistant immutable storage, restore drills, and the split between operational and legal retention. Invoke when 'we have backups but nobody has restored them' is true, after a near-miss, or before a major migration.

Create a Conventional Commit safely. Guards against committing to main, validates format, stages and commits. Chains to push-and-pr when user mentions push. Triggers: "commit", "/commit", "закоммить", "сделай коммит", "коммит и пуш", "commit and push"
