Use when the user mentions web pentest, API test, BOLA, IDOR, BFLA, mass assignment, SQLi, XSS, SSRF, SSTI, CSRF, JWT, OAuth, OIDC, SAML, GraphQL introspection, file-upload abuse, deserialization, or any WSTG-* / API:2023-* identifier.

Pentest — Web Application & API
Apply the methodology in the pentest-templates library when conducting web/API tests.
Library root
$PENTEST_LIBRARY — caminho absoluto deste repositório clonado (definido pelo instalador; veja INSTALL.md).
Phase content lives in 01-web-api/. Read 00-overview.md first, then walk numbered files in order.
Confirm scope and authenticated test accounts at multiple roles (low-priv, privileged, cross-tenant).
For each user request, locate the relevant phase file by topic and read the matching checklist item by stable ID (WEB-<PHASE>-<NN>).
When the user asks "how do I test X", expand the How to test block of the matching item — it contains tools, commands, payloads.
Map every finding to the per-item Mappings block (CWE / ATT&CK / CVSS) and emit a finding via templates/finding-template.md. Cross-reference frameworks/owasp-wstg.md or frameworks/owasp-api-top10.md.
For LLM-backed web apps, also pull pentest-ai-llm. For cloud-hosted backends with cloud-layer findings, also pull pentest-cloud.
When NOT to use
Mobile-app context → pentest-mobile (use this skill for the API surface only).
Pure infrastructure → pentest-infra-external / pentest-infra-internal.
Pre-conditions
Burp Suite / Caido / ZAP with TLS interception configured.
Target URL or asset list, plus ROE clarity on auth + payload classes.
OPSEC
Web pentest is generally noisy; coordinate with SOC if engagement is detection-aware.
No destructive payloads (DoS, data corruption) on production. Capture metadata only unless ROE permits sample extraction.
