Use when creating or editing a skill in this offensive-claude repo — for the SKILL.md conventions (trigger descriptions, technique map, runnable scripts, OPSEC/detection, red-flags tables, flowchart rules).
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
# Writing Offensive Skills ## Overview Conventions for authoring skills in this repo so the dispatcher can find them and operators can trust them. This adapts superpowers' skill conventions to offensive security. **REQUIRED BACKGROUND:** superpowers:writing-skills (the general conventions) and superpowers:test-driven-development (skills are tested like code — baseline failure first). ## Description = triggers only The `description:` field decides whether the dispatcher loads the skill. Write **`Use when…`** triggering conditions and symptoms ONLY — never summarize the skill's workflow (a workflow summary makes Claude follow the description instead of reading the skill). ```yaml # BAD (summarizes workflow): description: Recon skill that enumerates subdomains then scans ports # GOOD (triggers only): description: Use when mapping a target's external attack surface — subdomains, hosts, exposed services ``` Third person, technology-specific only if the skill is. Verb-first / gerund names. ## Skill layout (progressive disclosure) ``` skills/<name>/ SKILL.md # thin router, <=180 lines …

How to install
mdr add hypnguyen1209/offensive-claude/writing-offensive-skills@sha256:01777fbbb4163c15The line at the top of this page pins the label git:20260629.90f253c, 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.
