# Brunhilde - Head of Security Engineering
## Who Brunhilde Is
Drop Brunhilde into Claude and get a Head of Security Engineering whose entire job is triage and
routing: reading a request, diagnosing which discipline actually owns it, and handing it to a
named specialist with a brief, a sequence and a definition of done. She has run an organisation
where four separate teams had independently bought overlapping tooling for the same control
because each had solved its own problem correctly and nobody owned coherence, and the annual cost
of that incoherence was larger than the two headcount she had been refused. Brunhilde builds
nothing personally. She does not write the detection, tune the gateway, design the trust policy,
run the exercise or model the loss curve. She decides those things need doing, in what order,
against which measure, funded to what level, and by whom, and then she holds the specialists to
what they committed. A head of security engineering who does the work of her engineers has
removed an owner and acquired a second job.
Brunhilde is deliberately distinct from Bartholomea, the Security Program Director and CISO.

Ask Brunhilde something hard.
The board gave us a mandate and a budget. Decompose it, tell me who owns what, and what we are not doing.
CLAUDE · AS BRUNHILDE, HEAD OF SECURITY ENGINEERING
Brunhilde returns the mandate broken into workstreams, each routed to a named specialist with a brief, dependency, date and measure, the build versus buy calls on the tool estate, the sequencing logic and the critical path, the hiring and topology implications, and an explicit list of what is being deferred with the reason and the risk of deferring it.

// what's inside
What's inside this skill
- Decomposition of a broad mandate into owned workstreams
- Routing by name across the full security engineering bench
- Build versus buy, tool estate coherence and roadmap sequencing
- Team topology, hiring and the deliberately deferred list
Security leaders holding a board mandate and a long list, who need it decomposed, sequenced and assigned rather than admired.
What you're actually buying
Drop Brunhilde into Claude and get the head of security engineering who reads a messy request, works out which discipline actually owns it, and routes it by name with a brief.
Brunhilde runs the security engineering organisation: the platform and tool estate, build versus buy, the engineering roadmap, tooling and headcount budget, team topology and hiring, engineering standards, on-call, and how work is routed across thirty-five specialists. She is deliberately distinct from Bartholomea, who owns risk, policy, board reporting and regulatory posture for the whole security programme, while Brunhilde owns the engineering function that builds and runs the controls. Her value is triage: she decomposes a multi-part mandate into workstreams, assigns each to the right named specialist with a brief, a sequence and a measure, names what is being deliberately deferred, and refuses to let a request sit with whoever answered first. She does not do the hands-on work herself.
What you get
- →Decomposition of a broad mandate into owned workstreams
- →Routing by name across the full security engineering bench
- →Build versus buy, tool estate coherence and roadmap sequencing
- →Team topology, hiring and the deliberately deferred list

Questions about this product
What does the Brunhilde skill do?+
Turn a messy security mandate into an assigned plan: the right specialist on each workstream, with a brief, a sequence and what is deliberately deferred. Load it once into Claude Projects and you get a configured Head of Security Engineering without re-explaining context at the start of every session. This skill is for authorized, defensive security work only. Validate findings in your own environment, follow your rules of engagement and written authorization, and confirm current framework, vendor, and regulatory specifics before you act on them.
How do I install this skill file?+
Download the .skill package (it contains SKILL.md), paste the contents into Claude Projects Instructions or your AI's system prompt, add your own context and start your first session. Works with Claude, ChatGPT, or any AI chat that accepts system prompts.
Which AI tools does this skill work with?+
Works with Claude (recommended), ChatGPT, Gemini, Perplexity and Copilot, and any AI chat that accepts system prompts. Claude Projects gives the best results.
What is included in this download?+
One .skill package delivered instantly after purchase: the full SKILL.md role configuration plus a worked-example file with a real scenario so you see the quality before you rely on it. Pay once, keep forever, yours permanently.
How is this different from using Claude without the Brunhilde skill?+
Without a skill file your AI starts every session as a general assistant. With Brunhilde loaded it applies Head of Security Engineering methodology from the first message, with consistent quality every time. This skill is for authorized, defensive security work only. Validate findings in your own environment, follow your rules of engagement and written authorization, and confirm current framework, vendor, and regulatory specifics before you act on them.
Do I have to read it myself?+
No. The file is written for your AI to read, not for you. Upload it or paste it in once and the AI takes on the role. After that you just ask it questions the way you normally would. You're welcome to open it and read it, but nothing here depends on you doing that.
