What it does
Security Advisory is an agent skill from MidnightBSD/src. Handle a security fix end to end for MidnightBSD src - triage a FreeBSD security advisory (FreeBSD-SA-) or CVE against this tree, port the fix to master and both stable branches, add the UPDATING entry, and publish the matching MNBSD-YYYY-N advisory on the GitHub security advisories page. Use this whenever the user pastes or mentions a FreeBSD SA, a CVE, "does this affect us", "patch this on master/stable", or asks for a security advisory, even if they only ask for one of the steps.
Its SKILL.md is about 2.2k tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files, including scripts (for example `scripts/publish_advisory.py`).
It sits in Security, covering Vulnerability scanning. It works with GitHub. The repository describes itself as: MidnightBSD OS source code.
When your agent uses it
- Mentions a FreeBSD SA
- Does this affect us
- Patch this on master/stable
- Asks for a security advisory
Example prompts
- “does this affect us”
- “patch this on master/stable”
- “/security-advisory”
Requirements
- Python 3
Workflow steps
6 steps, taken from the step headings in SKILL.md.
- Triage: does it affect us?
- Port the fix on master
- UPDATING entry
- Push master, then the stable branches
- Publish the GitHub advisory
- Report
What it can do on your machine
Read from SKILL.md and the folder at commit 9450100. 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
Ships 2 files in scripts/ (Python), which the agent can run.
Shell commands in SKILL.md call:
gitpython3gh
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use git and gh, which can reach the network depending on how they are called.
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
Security Advisory loads about 2.2k tokens when it runs. Until then it costs about 127 tokens; SKILL.md has 953 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); the scripts in this folder are not scanned.
SKILL.md
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 953 words (~2,214 tokens).
“A security fix here is only done when four things are true: master and both supported stable branches carry the fix, each branch has an UPDATING entry, every push has been verified by re-fetching, and a GitHub advisory with the…”

Security Advisory is an agent skill from MidnightBSD/src. Handle a security fix end to end for MidnightBSD src - triage a FreeBSD security advisory (FreeBSD-SA-) or CVE against this tree, port the fix to master and both stable branches, add the UPDATING entry, and publish the matching MNBSD-YYYY-N advisory on the GitHub security advisories page.
When should I use Security Advisory?
Security Advisory fits situations like: mentions a FreeBSD SA; does this affect us; patch this on master/stable; asks for a security advisory.
How do I install Security Advisory in Claude Code?
Run `npx skills add MidnightBSD/src --skill security-advisory -a claude-code`. Or copy the skill folder (.claude/skills/security-advisory in MidnightBSD/src) into .claude/skills/security-advisory in your project. Claude Code loads it when a task matches its description.
How do I install Security Advisory in Codex?
Run `npx skills add MidnightBSD/src --skill security-advisory -a codex`. Or copy the skill folder (.claude/skills/security-advisory in MidnightBSD/src) into .agents/skills/security-advisory in your project. Codex loads it when a task matches its description.
Can I use Security Advisory in Cursor, Gemini CLI or GitHub Copilot?
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add MidnightBSD/src --skill security-advisory -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/security-advisory, .gemini/skills/security-advisory, .github/skills/security-advisory and .opencode/skills/security-advisory in your project.
What does Security Advisory need to run?
Going by SKILL.md and its folder, Security Advisory needs Python for the scripts in its folder and the command-line tools its instructions call (git, python3 and gh). Our summary lists: Python 3.
Does Security Advisory access the network?
SKILL.md contains no URLs. Its commands use git and gh, which can reach the network depending on how they are called. This is read from the text; nothing was executed.
Is Security Advisory safe to install?
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. The check reads SKILL.md only: the scripts in the folder are not scanned, so read them before running anything.
What licence does Security Advisory use?
Security Advisory has a licence file (the repository's licence) that doesn't match a standard licence. Read it on GitHub before reusing the skill.
How many tokens does Security Advisory use?
About 2.2k tokens (SKILL.md is roughly 8.9k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
What are the alternatives to Security Advisory?
Skills that share tags, products or a category with Security Advisory: Security Vulnerability Analysis (eclipse-ankaios/ankaios, 125 stars), Warp Vulnerability Triage (warpdotdev/warp, 65k stars), Cve Doctor (getlago/lago-front, 163 stars) and Deal With Security Advisory (paperclipai/paperclip, 98k stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
