What it does
Techstack Security is an agent skill from transilienceai/communitytools. Security-posture and third-party SaaS identification — security headers, CSP, HSTS, email auth, security.txt, plus payments/analytics/auth/CRM/support integrations.
Its SKILL.md is about 450 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 Security, covering Secure coding. 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 Secure coding
Example prompts
- “/techstack-security”
Workflow steps
2 steps, taken from the first numbered list in SKILL.md.
- Security posture — HTTP security headers, Content Security Policy, HSTS, email auth (SPF/DKIM/DMARC/MTA-STS), security.txt, certificate…
- Third-party / SaaS detection — payment processors, analytics, customer support, identity providers, CRM/marketing, error monitoring, A/B…
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 Security loads about 447 tokens when it runs. Until then it costs about 46 tokens; SKILL.md has 173 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.

Security Posture & Third-Party Tech-Stack
Scope
Two related lenses on a target:
- Security posture — HTTP security headers, Content Security Policy, HSTS, email auth (SPF/DKIM/DMARC/MTA-STS),
security.txt, certificate practices. - Third-party / SaaS detection — payment processors, analytics, customer support, identity providers, CRM/marketing, error monitoring, A/B testing, social/communication SDKs, media CDNs.
The two are coupled: CSP script-src and DNS TXT verifications reveal third-party services, while third-party domains contribute to the overall security surface.
Signals (input)
- HTTP response headers — security headers, CSP directives, HSTS
- DNS TXT records — SPF, DKIM, DMARC, SaaS verification tokens
- HTML — meta-tag security policies, embedded widgets/iframes
- Loaded JS / script-src URLs and globals
/.well-known/security.txt,/security.txt,/.well-known/change-password
Inferences (output)
- Security score (header coverage, CSP strength, email-auth strength, security.txt presence)
- CSP analysis (unsafe-inline/eval issues, allowed third-party domains)
- Email-auth grade (DMARC policy strength)
- Third-party SaaS catalogue by category, with integration mode (client SDK vs CSP-only vs DNS-only)
Techniques
When to use
- Pre-engagement security baseline
- Mapping supply-chain / SaaS exposure
- Identifying integrations that grant pivot opportunities (Auth0, Stripe webhook surface, Sentry DSN leakage, etc.)
- Phase 3 of tech-stack OSINT
