What it does

Techstack Infra is an agent skill from transilienceai/communitytools. Infrastructure tech-stack identification — cloud providers, CDN/WAF, DNS services, TLS/CT, DevOps tooling, plus asset discovery (domains, subdomains, IPs).

Its SKILL.md is about 460 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 DevOps & Cloud, covering Cloud networking. 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 Cloud networking

Example prompts

  • “/techstack-infra”

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 Infra loads about 462 tokens when it runs. Until then it costs about 43 tokens; SKILL.md has 180 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~43
When it runs · the whole SKILL.md, loaded when a task matches
~462

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.

Infrastructure Tech-Stack Identification

Scope

Identify the hosting and operational layer: cloud providers (AWS/GCP/Azure/DO/Linode/Vultr), PaaS (Heroku/Vercel/Netlify/Render/Railway/Fly), CDN (Cloudflare/Akamai/Fastly/CloudFront/Azure CDN), WAF (Imperva/Sucuri/F5/Fortinet), DNS provider, certificate authority, DevOps tooling (CI/CD, IaC, containers, orchestration), and the asset inventory (root domain, subdomains, IPs, certificates) that the rest of the engagement consumes.

Signals (input)

  • IP attribution (cloud IP ranges, ASN, WHOIS)
  • DNS records: A, AAAA, MX, TXT, NS, CNAME, SRV
  • TLS certificate metadata (issuer, SAN, validity, JARM)
  • CT logs (crt.sh)
  • HTTP headers tagging cloud/CDN/WAF
  • Repository config files (*.tf, Dockerfile, .github/workflows/*, Chart.yaml, etc.)
  • Asset inventory feeds — initial domain, subdomain enumeration, IP map

Inferences (output)

  • Primary cloud provider + region(s)
  • PaaS / serverless / container orchestration
  • CDN, WAF, DDoS / bot-management products
  • DNS service, email provider, SaaS verifications (TXT)
  • Certificate issuer & posture (automation, wildcard, validity window)
  • DevOps stack: CI/CD platform, containerization, IaC, monitoring, secret mgmt
  • Asset list: validated primary domain, all subdomains, IPs with cloud attribution

Techniques

See reference/patterns.md.

When to use

  • First step of every tech-stack engagement (asset inventory feeds all other domains)
  • Identifying CDN/WAF before choosing exploitation paths
  • CVE matching by server stack version
  • Supply-chain / SaaS exposure mapping (DNS verifications)
