harden
Threat-model, review, or reduce exploitable risk in software you are authorized to assess, including application code, APIs, identities, data flows, dependencies, CI/CD, configuration, cloud/IaC, and agentic capabilities. Use for security-sensitive changes, feature threat models, security audits, or evidence-backed remediation and retesting.

# harden: find the exploit path, not a pile of scary words
Security work is a risk-reduction decision made from evidence. It starts with
assets, actors, trust boundaries, and attacker goals; scanners and checklists
then help inspect the paths that matter. A clean tool output is not proof of
safety, and a CVE identifier is not proof that an application is exploitable.
## Purpose and scope
Use this skill to assess or change a system that handles identities, money,
personal or confidential data, administrative authority, external input,
untrusted files, third-party dependencies, build/deploy credentials, or an
agent that can retrieve data or invoke tools.
