Install
Works with every agent the skills CLI supports.
npx skills add https://github.com/transilienceai/communitytools --skill techstack-identification- 01
Install
Run the command in your project. The CLI asks which agents to install for.
- 02
Describe the task
Ask your agent for something this skill covers. It loads techstack-identification automatically when relevant.
- 03
Review the result
The agent follows the SKILL.md steps, scripts and references bundled with the skill.

The instructions your agent reads when the skill is triggered.
Tech Stack Identification
Passive OSINT reconnaissance to identify a target's technology stack. No credentials, no active scanning — only publicly available signals.
Quick Start
1. Provide company name (+ optional domain hint)
2. Run infra first (asset inventory) → frontend / backend / security / osint in parallel
3. Pass all signals into correlation → final report (JSON + Markdown)
Domain Sub-Skills
| Sub-skill | Identifies | Read |
|---|---|---|
| frontend | JS frameworks, meta-frameworks, CSS libraries, build tools, CMS via DOM/HTML/JS | frontend/SKILL.md |
| backend | Web servers, runtimes, languages, frameworks, DB, APIs, CMS | backend/SKILL.md |
| infra | Cloud, CDN/WAF, DNS, TLS/CT, DevOps, asset discovery (domains/subdomains/IPs) | infra/SKILL.md |
| security | Security headers, CSP, email auth, security.txt, third-party SaaS | security/SKILL.md |
| osint | Public repos (GitHub/GitLab), job postings/ATS, Wayback Machine | osint/SKILL.md |
| correlation | Cross-validation, confidence scoring, conflict resolution | correlation/SKILL.md |
Routing by Objective
| Objective | Mount |
|---|---|
| Full stack discovery | infra → (frontend, backend, security, osint) → correlation |
| CDN/WAF identification only | infra |
| API surface mapping | backend |
| Supply-chain / SaaS exposure | security + osint |
| CVE matching by version | backend + frontend (then correlation) |
| Migration / historical context | osint (web archive) + correlation |
| CMS fingerprint | frontend (HTML generators) + backend (CMS paths/cookies) |
| Asset inventory only | infra (domain discovery, subdomain enum, IP attribution, CT) |
Confidence Levels
- High: 3+ independent sources OR explicit identifier (header/meta/global) + supporting evidence + version known
- Medium: Single strong source OR multiple indirect signals (URL patterns, cookies, DOM attrs, job postings)
- Low: Speculative — single weak signal, conflicting data, or archive-only evidence
Computed in correlation/. Target distribution: 50-70% High, 20-35% Medium, <15% Low.

FAQ
What does the techstack-identification skill do?
OSINT-based technology stack identification. Routes to 6 domain sub-skills (frontend, backend, infra, security, osint, correlation) to discover a target's stack from publicly available signals.
How do I install techstack-identification?
Run npx skills add https://github.com/transilienceai/communitytools --skill techstack-identification in your project. The skills CLI detects the agents you use and copies the skill into the right folder. For Claude Code you can also place the skill folder at ~/.claude/skills/techstack-identification/ (personal) or .claude/skills/techstack-identification/ (project).
Which AI agents can use techstack-identification?
Any agent that supports the open Agent Skills format (a folder with a SKILL.md file), including Claude Code, Codex, Cursor, GitHub Copilot, Gemini CLI, Windsurf, Cline, OpenCode and more.
Is techstack-identification safe to install?
No partner security audit is available yet. Skills can run commands and scripts, so read the SKILL.md and any bundled files before installing.
Who maintains techstack-identification?
It is published by transilienceai in transilienceai/communitytools. It has 200 recorded installs.
