What it does
Techstack Frontend is an agent skill from transilienceai/communitytools. Frontend tech-stack identification — JavaScript frameworks, meta-frameworks, CSS frameworks, UI libraries, build tools, and CMS via DOM, JS globals, HTML, and bundle patterns.
Its SKILL.md is about 380 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files (for example `reference/patterns.md`).
It sits in Frontend & Design. It works with JavaScript and React. The repository describes itself as: Open-source Claude Code skills, agents, and slash commands for AI-powered penetration testing, bug bounty hunting, and security research. The licence is MIT.
When your agent uses it
- Frontend & Design work in your project
Example prompts
- “/techstack-frontend”
What it can do on your machine
Read from SKILL.md and the folder at commit 95fdc12. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Techstack Frontend loads about 382 tokens when it runs. Until then it costs about 49 tokens; SKILL.md has 147 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

- description
- Frontend tech-stack identification — JavaScript frameworks, meta-frameworks, CSS frameworks, UI libraries, build tools, and CMS via DOM, JS globals, HTML, and bundle patterns.
Frontend Tech-Stack Identification
Scope
Identify client-side technologies: JavaScript frameworks (React, Vue, Angular, Svelte), meta-frameworks (Next.js, Nuxt, Gatsby, Remix), CSS frameworks (Tailwind, Bootstrap, Material UI), state management, build tools, CMS generators, and analytics SDKs from rendered HTML/JS.
Signals (input)
- HTTP response bodies (HTML)
- JavaScript global variables (
window.*) - DOM attributes (
data-*,ng-*,_ngcontent-*) - Script src URL patterns (
/_next/,/wp-content/, etc.) <meta name="generator">tags- HTML comments
- CSS class patterns
- JSON-LD / structured data
- Source map exposure
Inferences (output)
- JS framework + version (e.g. React 18.2)
- Meta-framework (implies host framework — Next.js → React)
- CMS / static site generator (WordPress, Drupal, Hugo, Ghost)
- CSS framework + UI library
- Build tool (Webpack, Vite, Parcel)
- Analytics / tracking SDKs (GA, Mixpanel, Hotjar, FullStory)
- Source map exposure (security finding)
Techniques
When to use
- Phase 2/3 of a tech-stack OSINT engagement
- Mapping client-side attack surface for XSS / DOM-based testing
- Validating CMS/version for CVE matching
- Identifying SaaS dependencies via third-party scripts
