io.github.peterkrueck/Claude-Code-Development-Kit/deploy

Test and deploy changes safely. Discovers deploy targets, runs fail-stop gates before going live, optionally shadow-deploys and swaps, then runs report-only post-deploy checks. This is a TEMPLATE — customize the commands and checks for your specific deployment pipeline.

io.github.jnMetaCode/superpowers-zh/workflow-runner

在 Claude Code / OpenClaw / Cursor 中直接运行 agency-orchestrator YAML 工作流——无需 API key，使用当前会话的 LLM 作为执行引擎。当用户提供 .yaml 工作流文件或要求多角色协作完成任务时触发。

io.github.tsantalis/RefactoringMiner/refactoringminer-review

Use RefactoringMiner MCP and AST diff views to review pull requests, commits, or local worktrees by separating detected refactoring structure from behavior-relevant code changes. Use this when the user asks Claude Code to review non-refactoring changes, inspect moved or renamed code with WebDiff, or explain which changes are refactorings versus semantic edits.

io.github.browserbase/skills/safe-browser

Build local constrained-browser agents with a safe_browser tool that owns CDP, enforces a domain allowlist with Fetch interception, and lets a runtime Claude Agent SDK agent complete browsing tasks without raw browser, shell, or CDP access. Use when the user wants an agent to browse or scrape while staying on approved domains, demo blocked off-domain navigation, or generate a safe browser client.

io.github.shuvonsec/claude-bug-bounty/security-arsenal

Security payloads, bypass tables, wordlists, gf pattern names, always-rejected bug list, and conditionally-valid-with-chain table. Use when you need specific payloads for XSS/SSRF/SQLi/XXE/NoSQLi/command injection/SSTI/IDOR/path-traversal/HTTP smuggling/WebSocket/MFA bypass, bypass techniques, or to check if a finding is submittable. Also use when asked about what NOT to submit.

io.github.shuvonsec/claude-bug-bounty/mobile-pentest

Mobile app pentest for bug bounty (Android APK + iOS IPA) — runtime-first workflow: install app, proxy through Burp/mitmproxy, drive the UI, capture packets, then test the API exactly like a web target; escalate to decompile (apktool/jadx) and Frida/objection only when traffic is SSL-pinned, encrypted, or absent. Covers APK/IPA decompile for hardcoded secrets + hidden API endpoints + base URLs the web app never exposes, exported-activity and deeplink intent injection, WebView addJavascriptInterface bridge abuse, SSL pinning bypass (objection patchapk / Frida CertificatePinner + checkServerTrusted hooks), OkHttp interceptor chain to recover request signing, JNI native-lib triage, and the quick apktool/grep secret + endpoint sweep. Use when the program scope includes a mobile app, when web recon dries up and you need a fresh attack surface, or when traffic is pinned and you must MitM it.
