encod3d-sec Skill Wiki ArsenalFast PARALLEL wiki lookup engine over wiki/techniques + wiki/payloads + wiki/tools + wiki/cheatsheets for a surface/service/vuln-class. Two modes - quick (one qmd search, cheap, fire constantly) and deep (4 parallel subagents, one per area, merged ready-to-use arsenal card, cached). This is the fast path arsenal that `arsenal` delegates to; the hunt-* skills each inline their own qmd_query and can hand off here for a parallel lookup. Use for "what do I use against <surface>", "arsenal for <X>", "deep/full arsenal", "tool + payload + technique + cheatsheet for <X>", "fast wiki lookup", "parallel wiki search", any "how do I attack/exploit <service|vuln-class>" where you want the documented tooling + payloads before hand-rolling.

-
marvin-lijunzan Bundle Pre Submission ReviewerRuns a pre-submission review of a technical paper across five dimensions: macro logic, writing details, English grammar, LaTeX formatting, and figure quality. Uses a reviewer-style severity taxonomy (CRITICAL / MAJOR / MINOR) and flags banned AI-tone vocabulary and em-dash misuse.

johnqtcg Bundle Create PrCreate evidence-backed pull requests to the GitHub main branch with strict preflight, quality, and security gates. Use when users ask to create/submit/open/update a PR to main (including private repos), decide draft vs ready state, and provide reviewer-ready context for team review.
-
johnqtcg Bundle Go Review LeadOrchestrate a comprehensive Go code review by triaging code changes, dispatching vertical review skills (security, concurrency, error, logic, performance, quality, test, observability) as parallel agents, then consolidating results into a unified report. Use for full Go PR review or comprehensive code review. Replaces the monolithic go-code-reviewer with focused parallel analysis.
-
johnqtcg Bundle Security ReviewExploitability-first standalone security review of code changes, diffs, PRs, or services. Use when asked for a security review, security audit, vulnerability assessment, or pre-merge security check (安全审查/安全评审/漏洞排查) — covers auth, input, secrets, API, data, concurrency, container, third-party, and dependency risk across Go, Node.js/TypeScript, Java, and Python, with mandatory evidence, false-positive suppression, scope-based depth (Lite/Standard/Deep), and CWE/OWASP-mapped machine-readable output. NOT for general-purpose Go code review — use go-review-lead for that (it dispatches go-security-review as its security dimension); this skill is the deeper security-only process with mandatory gates and audit-grade output.
-
johnqtcg Bundle Go Dependency AuditGo dependency audit specialist for CVE scanning (govulncheck), license risk triage, outdated dependency detection, upgrade impact analysis, and supply chain security. ALWAYS use when auditing go.mod dependencies, running govulncheck, checking license compatibility, planning dependency upgrades, or investigating supply chain risks in Go projects. Read-only by default — emits a remediation plan instead of mutating go.mod/go.sum. Complements security-review (code-level) with module-level supply chain analysis.
-
dauquangthanh Bundle Kiss Dependency Audit 2Audits third-party dependencies: lists direct + transitive deps, cross-references against CVE databases (via WebSearch/WebFetch), surfaces licence conflicts and abandonware. Records audit as a dated file so subsequent runs show drift. Use when checking for security vulnerabilities in dependencies, performing a licence audit, or reviewing third-party packages for risk.
