Writes security user stories and security-aware acceptance criteria that fit a Scrum backlog, converting threats, scan findings, and compliance requirements into INVEST-compliant stories with Given/When/Then criteria and regression tests. Use this (not general story writing) whenever the story or criteria concern a security control, vulnerability, or compliance requirement. Triggers on: "write a security story", "security acceptance criteria…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

Use when security is a property of the feature, not separate work. 4. **Compliance story** — implementing a named control from a framework (PCI-DSS requirement, MAS TRM section). Must cite the specific control number so auditors can trace it. ## Templates ### Security control story ```markdown ### [ID] [Control title] **As** [the system / a security role], **I want** [security control], **so that** [risk is mitigated]. **Threat:** [STRIDE category or threat-model reference] …

How to install
mdr add timwukp/agent-skills-best-practice/security-story-writing@sha256:b8a1351bcc8fd7a2The line at the top of this page pins the label v1.0.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
