Security Plan Gap
Overview
Find missing security requirements before code exists. This skill turns design omissions into actionable plan additions.
When to Use
- writing a feature plan or architecture
- reviewing a spec before implementation starts
- breaking work into tasks that may cross trust boundaries or handle sensitive data
Workflow
- Read the current plan, spec, or task breakdown.
- Load
references/plan-gap-checklist.md.
- Load
../shared/common-web-threats.md, ../shared/finding-schema.md, and the relevant stack profile if known.
- Produce a gap report with missing controls, risk scenarios, and suggested plan additions.
- End with a closing coverage note using the shared headings: Reviewed / Not reviewed / Assumptions / Tools run.
Guardrails
- Treat missing requirements as gaps, not confirmed vulnerabilities.
- Prefer concise, actionable additions over generic best-practice lists.
- Lower confidence when the stack or architecture is only partly defined.
- Treat this skill as the default planning-stage review pass when
sentinelx-prime invokes it automatically.
