A contract workflow for Data Processing Agreements under Article 28 of the GDPR, the EU privacy rule for controller–processor relationships, and arrangements between joint controllers under Article 26.

Reviewing, drafting, or redlining DPAs, German AVVs, and joint-controller agreements in English or German.

It gives privacy or commercial lawyers a clause-by-clause basis for reviewing, drafting, or negotiating these arrangements.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00197	$0.04202
Opus 5.5	$0.00079	$0.01681
Sonnet 5.5	$0.00039	$0.00840
Haiku 4.5	$0.00020	$0.00420

Security

Grade A, and why

dpa-art28 scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 194 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Purpose

This skill governs all work on controller–processor contracts (Art. 28 GDPR) and joint-controller arrangements (Art. 26 GDPR). It produces:

Reviews of existing DPAs (quick or negotiation-grade)
Drafts of new DPAs / AVVs from modular templates (DE / EN)
Redlines in response to counterparty drafts
Joint Controller Agreements (JCA / Art.-26-Vereinbarung)

Who this is for, and what kind of work this is

Operator. This skill is written for a privacy or commercial lawyer, or a trained paralegal working under attorney supervision — someone who can read a DPA clause and exercise judgement on the output, not a lay business user. It assumes legal literacy but no special AI fluency beyond describing the scenario and the side you act for in plain language.

Work shape. The work is bounded and transactional: a single contract (or counterparty draft) reviewed, drafted, or redlined against a fixed Art. 28 / Art. 26 benchmark, clause by clause — pattern-matched against known requirements and defect catalogues, not open-ended advisory. That bounded shape is what lets the skill take a structured, checklist-driven posture; anything outside the pattern (novel structures, contested law, transfer-risk judgement calls) is surfaced and handed back, not resolved silently.

Status of the output. What this skill produces is drafting and review support — not legal advice, and not in itself a privileged work product. Treat storage, sharing, and retention per your firm's work-product and privilege policy; the attorney–client relationship and any privilege attach through the supervising lawyer, not through this skill.

Mode router — ALWAYS run first

Before doing anything else, classify the request into ONE of these modes:

Mode	Trigger pattern	Workflow file
`REVIEW_QUICK`	"Is this DPA compliant?", "Art. 28(3)(a)–(h) check", short turnaround, sign/no-sign decision needed	`workflows/review-quick.md`
`REVIEW_NEG`	"Review this for negotiation", "give me redline points", "what should we push back on", deeper diligence	`workflows/review-negotiation.md`
`DRAFT`	"Draft a DPA", "create an AVV", "we need a processor agreement for [X]", greenfield	`workflows/draft.md`
`REDLINE`	Counterparty has sent a DPA, user wants tracked-changes / counter-proposals	`workflows/redline.md`
`JOINT_CONTROLLER`	"Art. 26", "joint controller", "JCA", or roles screen reveals JC not processor relationship	`workflows/joint-controller.md`

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
