Implement, harden, or review defensive security controls for REST APIs, including authentication and authorization boundaries, validation, rate limiting, abuse prevention, resource limits, SSRF defenses, safe errors, logging, and security tests. Use when API security, endpoint hardening, threat review, rate limiting, token handling, or sensitive business-flow protection is an explicit concern. Do not use for ordinary endpoint logic without meaningful security scope or for offensive exploitation.
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.
What the file says
# Superior API Security Protect the API at the server-side trust boundary while preserving its documented contract. Base controls on the actual actors, resources, business impact, deployment topology, and existing security architecture; do not add security middleware by checklist alone. ## Establish the security contract Before changing code, identify: - exposed operations, versions, and consumers; - public, authenticated, privileged, internal, webhook, and machine-to-machine callers; - sensitive resources, properties, actions, and business flows; - where identity is established and where authorization is enforced; - proxies, gateways, caches, queues, third-party services, and outbound network access; - expected traffic, burst behavior, payload size, operation cost, and failure tolerance; - security controls already owned by infrastructure versus the application. Trace the effective request path. Do not assume a gateway, framework default, or client-side check enforces the requirement until configuration and behavior prove it. ## Select controls from risk …

How to install
mdr add kodekateam/superior-skills/superior-api-security@sha256:77f4ba6efe60fa9cThe line at the top of this page pins the label git:20261015.f413813, 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.
