Use when about to take any outward or offensive action (request, payload, persistence, lateral movement, exfil, or feeding captured traffic to the model) — to decide detection footprint, cleanup, and secret redaction first.
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
# OPSEC Discipline ## Overview Decide the detection footprint and cleanup **before** acting, not after. Every offensive technique in this repo pairs with the telemetry it generates and a detection signature — use that pairing to choose the quieter path and to know what you'll need to clean up. ## Before acting, answer three questions 1. **Detection** — what telemetry does this generate? Which Sigma/EDR rule would catch it? (Each domain skill's OPSEC & Detection table has this.) Pick the lower-noise variant when one exists. 2. **Cleanup** — what does this touch (files, registry, services, accounts, tickets)? How is it reverted? Stage the cleanup before you create the artifact. 3. **Secret hygiene** — any captured traffic / output that reaches the model or the report must be redacted at the boundary: `python skills/coding-mastery/scripts/_lib/redact_headers.py < exchange.txt` (or `redact_text()`), so Authorization/Cookie/API-key/JWT values never land in context or the report. ## Red Flags — STOP, decide OPSEC first - "I'll worry about cleanup after I'm in" (you won't; decide now) - "Just paste the raw request/response" (redact secrets at the boundary first) …

How to install
mdr add hypnguyen1209/offensive-claude/opsec-discipline@sha256:b87303e014dee9a7The line at the top of this page pins the label git:20260629.9f4a1a5, 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.
