Security
Security agent skills give AI agents disciplined security workflows: code review for vulnerabilities, secret handling, dependency audits, and hardening checklists. Every skill on SkillMD also passes its own safety review before listing, with capability flags shown on each page.
-
bagelhole Bundle Ctr Snippet Batch OptimizeBatch-rewrites page titles, meta descriptions, and matching on-page headlines (including JSON-LD where the site duplicates the title) using tiers from Google Search Console data—prioritizing high impressions with zero or low CTR on page 1–2, then deeper positions. Encodes repeatable CTR patterns from production workflows: numbers and list counts in titles, bracket qualifiers, question-led descriptions, concrete examples, deduped title phrasing, and current-year refresh on time-sensitive pages. Use after a GSC audit or alongside gsc-ahrefs-browser-audit output when the user wants implementation, not just research. Trigger when the user mentions batch title tags, meta rewrites, GSC tiers, zero-CTR pages, snippet optimization, or SEOLayout-style title/description updates across many URLs.
-
bamboo-dcm Bundle Pitch Deck AuditAudit a fundraise deck (or structurer proposal, M&A teaser) using a sector-tuned lens. Outputs a per-slide gap analysis, red-flag checklist, and rewrite suggestions. TRIGGER when user asks to audit / review / critique a pitch deck, fundraise deck, investor deck, structurer proposal, or M&A teaser; says "audit my deck", "review this pitch deck", "what's wrong with my Series A deck", "critique this fundraise deck"; or shares a deck PDF asking for feedback. DO NOT TRIGGER when user asks to design slides visually (use design tools), generate a deck from scratch (this skill audits existing decks; use a content-authoring approach for greenfield), or draft email follow-ups to investors.
-
benchflow-ai Bundle Repo ScrubScan a git repository for leaked secrets and env keys, a missing LICENSE, and unclear authorship (bot or non-employee committers), then optionally fix the safe parts. Reports secret matches with values redacted, .env files tracked or untracked, secrets found in git history, license presence, and committer domains. With --fix it untracks .env, adds it to .gitignore, writes a values-blanked .env.example, and scaffolds a LICENSE; --redact-code also replaces secrets found in tracked source. Never rewrites git history automatically — it prints the command instead. Use before publishing, open-sourcing, transferring, or sharing a repository, or when asked to find leaked keys, add a license, or check IP hygiene. Trigger phrases: 'scan for secrets', 'is there an API key in this repo', 'check before open-sourcing', 'add a license', 'clean this repo before sharing'.

bishalu Skill Engineering RouterDecide which engineering skills should run before starting non-trivial engineering work — a feature, a refactor, a bug, a review, or an audit — when more than one installed skill could plausibly claim it. Picks at most one lifecycle owner, names the supporting skills that augment it, and says when to escalate to a security or diagnosis specialist. Skip for a one-line edit, a direct question, or work already inside a chosen skill.

boojack Bundle SimplifyManually invoked code-cleanup capability that reviews changed code for reuse, simplification, efficiency, and abstraction-level issues, then applies verified behavior-preserving fixes. Use only when the user explicitly invokes or names the simplify skill. Do not activate for correctness or security review, bug fixing, formatting-only requests, or broad refactoring.
-
breferrari Skill AuditReview the memory stores and keep them lean — walk each memory and recommend KEEP, DROP or UPDATE with reasons, acting only on what the user approves.

Also trigger when the user mentions "WooCommerce plugin", "Woo extension", "WooCommerce add-on", "payment gateway plugin", "shipping method plugin", or any plugin that touches orders, products, carts, checkout, or the WooCommerce REST API. Even if the user just says "start a new plugin" in the context of a WooCommerce project, use this skill. This skill should be the first thing consulted before writing any code for a WooCommerce plugin project.

mozilla Bundle Firefox Addon Policy CheckScans a Firefox WebExtension/add-on codebase for likely violations of Mozilla's Add-on Policies — permissions scope, remote code loading, CSP relaxation, data collection & consent (manifest data_collection_permissions), monetization rules (ads, affiliate links, crypto miners), source/obfuscation requirements, and "No Surprises" feature disclosure. Use whenever someone is building, reviewing, or about to submit a Firefox extension to addons.mozilla.org (AMO) and wants a policy/compliance/review-readiness check, or wants to know if their extension might get rejected or blocked — even without the word "policy," e.g. "will AMO reject this," "check my manifest.json," "audit my extension for Mozilla compliance." UNOFFICIAL, THIRD-PARTY HEURISTIC TOOL, NOT BUILT OR ENDORSED BY MOZILLA — always say so, before running it and in the report, and make clear a clean scan is NOT a guarantee of Mozilla approval.
