What it does
Opsec Discipline is an agent skill from hypnguyen1209/offensive-claude. 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
Its SKILL.md is about 560 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Security, covering Red teaming and adversary simulation. The repository describes itself as: Offensive security toolkit for Claude Code covering red team, exploit dev, AD attacks, EDR bypass, mobile pentest. The licence is MIT.
When your agent uses it
- About to take any outward
- Offensive action (request
- Lateral movement
- Feeding captured traffic to the model) — to decide detection footprint
Example prompts
- “/opsec-discipline”
Requirements
- Python 3
Workflow steps
3 steps, taken from the first numbered list in SKILL.md.
- Detection — what telemetry does this generate? Which Sigma/EDR rule would catch it? (Each
- Cleanup — what does this touch (files, registry, services, accounts, tickets)? How is it

What it can do on your machine
Read from SKILL.md and the folder at commit a506ad3. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
python
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Opsec Discipline loads about 561 tokens when it runs. Until then it costs about 60 tokens; SKILL.md has 279 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

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
- 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.
- Cleanup — what does this touch (files, registry, services, accounts, tickets)? How is it reverted? Stage the cleanup before you create the artifact.
- 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(orredact_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)
- "Loudest exploit is fine, it works" (pick the variant with the smaller footprint)
- "Persistence now, document later" (persistence on un-authorized hosts is out — see scope-discipline)
- "The token's only in a log" (a logged secret is a leaked secret — mask it)
Rationalizations
| Excuse | Reality |
|---|---|
| "OPSEC slows me down" | Unplanned noise/loot is how engagements get burned and how data leaks. |
| "It's an internal tool log" | Logs get shipped, shared, and indexed. Redact. |
| "Cleanup is a reporting-phase task" | You can't clean what you didn't track. Track at action time. |
OPSEC is part of every action, not a phase. Detection-awareness also strengthens the defensive value of the finding (you can tell the client exactly how to catch it).
