Collaborative purple-team operations — threat-informed adversary emulation.
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
# Purple Team & Adversary Emulation ## Evidence contract `detection_validator.py` scores supplied outcomes; it does not execute detection rules or adversary techniques. Provide boolean `executed`, valid technique IDs, known outcomes, and non-negative finite detection times. `--attack-version` sets Navigator metadata (legacy default 15); it does not validate IDs against a release. Separate **observed**, **inferred**, and **unverified** conclusions. For each finding, record the source/artifact reference, SHA-256 when a file is available, collection time, validation performed, limitations, and next verification step. Extraction confidence is not maliciousness confidence; unknown maliciousness stays unknown. Generated queries/rules are unverified until tested against the intended backend and labeled positive/negative fixtures. Never present simulated results as live evidence. Select an execution mode: `offline` (default for supplied files), `passive` (external read-only collection), `authorized-active` (explicit target scope and permission), or `simulation` (synthetic/lab inputs). Record the mode in handoffs. …

How to install
mdr add masriyan/claude-code-cybersecurity-skill/22-purple-team@sha256:46c90e6bce6d2d31The line at the top of this page pins the label v3.3.0, 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.
