a-v-ershov Skill Audit PerformanceMeasure the built product's performance against the spec's quality-attribute scenarios — p50/p95 on the hot paths, throughput at the target load, asset weight and client render cost, query plans, the resource and cost envelope. Use in the release phase (run by release-product) or standalone once features are built. Read-only: it measures, reproduces the slow path and ranks what it finds, but never edits product code and never installs a profiler or load tool it wishes it had — an unavailable measurement is recorded as unmeasured, and tooling is setup-dev-environment's job. Files blockers and majors as rework tasks and writes .dev-skills/release/performance-audit.md.

ainova-systems Skill Spec Audit DocsAudits documentation claims against the code and classifies each mismatch as drift or violation. Read-only by default.
Audited -
alawein Skill Repo ReviewUse when a whole repo needs a health audit before you trust or own it. Judges structure, docs truth, test coverage, dead code, and drift between docs and code, then emits findings shaped for triage. An opt-in ownership lens hunts single-owner assumptions when a one-person repo becomes a team surface. Distinct from orient-repo, which maps a repo without judging it.
Audited -
willianbs Bundle Threat ModelerBuilds asset- and STRIDE-based threat models before deep security audits. Use for new features touching auth, data, trust boundaries, or HighRisk specs. Emits THREAT_MODEL. Never invents exploits or replaces security-auditor findings.
-
willianbs Bundle Security AuditorThreat-aware security assessment of code and trust boundaries with evidence-based findings. Use for auth, PII, payments, integrations, or when review escalates. Emits SECURITY_REPORT. Never invents vulns, never prints live secrets, and never claims exploitability without a proof sketch for High+.
-
willianbs Bundle Performance AuditorEvidence-based performance and scalability audit against SLOs and budgets. Use for slow paths, capacity risk, or review escalation. Emits PERF_REPORT. Never micro-optimizes without measurement or recommends changes below the noise floor.
-
adelabdelgawad Skill Fusion PanelPanel reasoning for high-stakes decisions — take several INDEPENDENT passes at the same question (blind to each other), then synthesize consensus, contradictions, unique insights, and blind spots into one grounded answer. Inspired by fusion-fable's "independence, then synthesis". Zero setup — uses parallel Claude subagents, no external CLIs and no slash command. Use for architecture choices, risky migrations, security-sensitive changes, stubborn bugs, and ambiguous trade-offs where being wrong is costly.
Audited -
adelabdelgawad Skill Fetch ValidateAudit fetch pattern compliance — checks server actions use /backend/ URLs, API routes use backendFetch with (token, headers), client uses api not fetchClient, and CSRF flows correctly.
-
adelabdelgawad Skill Rust Quality GatesNon-skippable verification chain for Rust services — fmt, clippy with deny-warnings, cargo check, sqlx offline-cache drift, audit, migration safety, and the no-allow policy. Use after generating or modifying Rust code, before declaring any Rust work done, or when asked to gate or validate a Rust project. Do not use for Python validation (ruff/mypy are wired separately).

camunda Bundle CI Security ComplianceEnforces GitHub Actions security and compliance for this monorepo. Use when adding third-party actions, handling secrets, defining permissions, and reviewing CI security trade-offs.

mqmalagris Bundle Aso CraftApp Store Optimization for iOS and Android from one per-locale Markdown source. Probes keyword candidates against live App Store data for competitor density, incumbent difficulty and search intent (free, no API key), assigns each surviving term to the surface that actually indexes it per store, then lints the listing: hard character limits, target-keyword coverage gaps, keyword budget spent twice, keyword stuffing, and URLs or support emails broken by translation. Use when the user wants to do ASO, research or validate app store keywords, pick an app name / subtitle / short description / keyword field, check store metadata character limits, localize a store listing for search, audit why an app is not ranking, prepare an App Store or Play submission, or runs /aso-craft.

mqmalagris Bundle Review PassSingle review-only entry point for an existing diff — runs a live-run check (`/run`) → code-review → implementation-review (and security-audit only when the change touches a trust boundary), then consolidates every finding into one go/no-go verdict. Use when you have a change ready and want it reviewed without running the whole dev-flow build chain. Triggers on /review-pass, "review this diff", "review my changes", "is this ready to commit", "give this a once-over". NOT for reviewing a remote GitHub PR (use /code-review) or for a task still being built (use /dev-flow).
-
mqmalagris Bundle Audit ReportRender audit findings as a designed, paginated A4 PDF report with a cover page, severity donut and category bar charts, colored severity chips, evidence-backed strengths, prioritized recommendations, and copy-ready GitHub issue blocks. English by default, with a pt-BR label pack for when the user is working in Portuguese. Self-verifying (page count plus page rasterization before delivery), and it leaves a re-runnable generator script beside the report. Use when the user asks for a security audit report as a PDF, a findings report with charts, a formatted deliverable from a code review or audit, GitHub issue text generated from findings, or says "gere um relatório em PDF" / "relatório de auditoria". Pairs with /wstg mode 2 (which produces the findings) and works for any audit, not only security. Runs in an isolated venv, installs nothing globally.

mqmalagris Bundle Security AuditFocused security review of a CHANGE (a diff, a branch, a PR), layered on the wstg-security-testing skill. Finds HIGH-CONFIDENCE, concretely exploitable vulnerabilities the change newly introduces (injection, broken authn/authz, secrets and data exposure, unsafe deserialization, crypto misuse, SSRF) and audits dependencies when a lockfile moved, using the repo's own package manager. Runs as Check 7 of /implementation-review, and standalone when the user says 'review this diff for security', 'is this change safe', 'security-check my PR', 'threat check this branch', or before shipping something that touches auth, user input, secrets, or untrusted data. NOT for whole-codebase or posture audits ('audit this repo', 'is my app secure', 'find every IDOR', 'auditoria de seguranca') — this skill is diff-scoped and its precedents suppress absence-shaped findings, so on a codebase-wide ask it can report clean on a vulnerable repo; route those to /wstg mode 2. Maps findings to WSTG IDs via /wstg, then reports only finding
-
mqmalagris Bundle Implementation ReviewPre-commit quality gate. Invoke before every git commit, after the live-run check (/run). Seven checks run as parallel subagents: plan gaps, use-case coverage gaps, missing test scenarios, test-philosophy violations (Kent Dodds Testing Trophy), SOLID violations, Clean Code violations, and security vulnerabilities (via /security-audit, which layers on /wstg). Surfaces findings before they land in history. Also invoke when the user says 'review this', 'am I done', 'did I miss anything', or 'check the quality'.

orangehrm Skill MailReference for OrangeHRM's email system — `EmailService` (the main service for composing and sending mail), the `EmailConfiguration` entity that stores SMTP/sendmail settings (with `smtpPassword` encrypted at rest), `MailerSubscriber` that processes the email queue on `KernelEvents::TERMINATE` (deferred sending so the user gets their response before SMTP latency), the Twig template structure under per-plugin `Mail/templates/<locale>/<eventName>/`, `queueEmailNotifications()` for the standard event-driven flow, and the `Mailer` / `MailMessage` / `MailTransport` low-level utilities wrapping Symfony Mailer. Use whenever the user is sending an email (notification on save, password reset, leave-approval notice), adding a new email template, debugging "why didn't the email send", or asking about SMTP configuration. Companion to `events` (event subscribers trigger emails), `security-primitives` (SMTP password is encrypted via the EmailConfigurationListener), `config` (`KEY_SENDMAIL_PATH`), `services` (EmailService is

orangehrm Skill Security PrimitivesReference for OrangeHRM's cryptographic and password-handling primitives — the `Cryptographer` class (AES-256-GCM with random nonces for new ciphertext, legacy AES-128-ECB still accepted on decrypt for backward compatibility), `KeyHandler` for the file-based crypto key lifecycle (created at install when data encryption is enabled, stored at `lib/confs/cryptokeys/key.ohrm`), `EncryptionHelperTrait` for accessing the Cryptographer from EntityListeners with the `encryptionEnabled()` guard, `PasswordHash` wrapping PHP's `password_hash`/`password_verify` with `PASSWORD_BCRYPT` cost 12, the `GCMAES256.` prefix marker that distinguishes new vs legacy ciphertext, the encrypt-on-write + decrypt-on-read symmetric round-trip pattern via EntityListeners, and the CSRF token handling via Symfony's `CsrfTokenManagerTrait`. Use whenever the user is adding a new sensitive column that needs encryption, debugging crypto failures, asking about key rotation, handling passwords, or implementing CSRF protection. Companion to `entit
