What it does
Techstack Backend is an agent skill from transilienceai/communitytools. Backend tech-stack identification — web servers, runtimes, languages, frameworks, databases, APIs, and CMS via HTTP headers, cookies, error pages, and API discovery.
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 Backend & APIs, covering Backend development. It works with OpenAPI and GraphQL. 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
- Tasks that involve Backend development
Example prompts
- “/techstack-backend”
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 Backend loads about 381 tokens when it runs. Until then it costs about 46 tokens; SKILL.md has 140 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
- Backend tech-stack identification — web servers, runtimes, languages, frameworks, databases, APIs, and CMS via HTTP headers, cookies, error pages, and API discovery.
Backend Tech-Stack Identification
Scope
Identify server-side technologies: web servers (nginx, Apache, IIS), runtimes (Node, Python, PHP, Ruby, Java, .NET), backend frameworks (Express, Django, Flask, Rails, Laravel, Spring, ASP.NET), databases (Postgres, MySQL, Mongo, Redis), CMS (WordPress, Drupal, Magento), and API surfaces (REST, GraphQL, OpenAPI).
Signals (input)
- HTTP response headers —
Server,X-Powered-By,X-AspNet-Version,X-Drupal-*,X-Generator, etc. - Cookies — session-name fingerprints (
PHPSESSID,JSESSIONID,_rails_session, ...) - Error page bodies (404, 500)
- Path patterns hinting CMS (
/wp-admin/,/sites/default/) - API subdomains and OpenAPI/Swagger/GraphQL endpoints
robots.txtdirectives
Inferences (output)
- Web server + version
- Runtime / language + version
- Backend framework (with implied runtime)
- CMS + version
- Database (often indirect — via ORM dependency or hosted-DB DNS)
- API style (REST/GraphQL/gRPC) and authentication scheme
Techniques
When to use
- Phase 2/3 of a tech-stack OSINT engagement
- Mapping server-side attack surface (RCE, SSRF, deserialization)
- CVE matching by server + version
- Locating GraphQL / OpenAPI for follow-on api-security testing
