About security-and-hardening
security-and-hardening
Hardens code against vulnerabilities
security-and-hardening is an agent skill from Addy Osmani's agent-skills collection that brings security-first practices to web application development. It asks the agent to treat every external input as hostile, every secret as sacred, and every authorization check as mandatory. Security is framed as a constraint on every line of code that touches user data, authentication or external systems, rather than a phase at the end of a project. The skill's process starts with a threat model. Controls added without one are described as guesses, so before hardening, the agent is asked to spend a few minutes thinking like an attacker. The skill applies when building anything that accepts user input, implementing authentication or authorization, storing or transmitting sensitive data, integrating with external APIs or services, adding file uploads, webhooks or callbacks, and handling payment or personal data. It is listed on skills.sh, with its security audit results shown there. The skill is a guide for how an agent should write code, not an audit tool, and it suits developers and agents who build features that handle user data and want the security reasoning built in from the start.
