Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00122 | $0.02296 |
| Opus 5 | $0.00061 | $0.01148 |
| Sonnet 5 | $0.00024 | $0.00459 |
| Haiku 4.5 | $0.00012 | $0.00230 |
Grade A, and why
808-regulations-eu-digital-markets-act 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 9d 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 — 103 lines — stays where its author put it; the contents beside it link to each section on GitHub.
EU Digital Markets Act Regulation for Java Enterprise Gatekeeper Platform Controls
Use this Skill to review Java enterprise applications, platform APIs, marketplaces, app stores, advertising systems, ranking systems, identity services, browser or operating-system integrations, messaging interoperability, business-user portals, data access APIs, analytics pipelines, CI/CD workflows, or operational tooling that may support Digital Markets Act (DMA) gatekeeper-platform obligations.
Apply this Skill to determine what engineering controls, compliance evidence, and escalation paths are needed before a system is released, connected to production platform data, exposed to business users, or used to operate a core platform service.
This Skill is not legal advice. It helps Java engineers, architects, tech leads, platform teams, product teams, and reviewers identify when DMA concerns may apply and how to translate gatekeeper-platform expectations into enterprise architecture controls such as interoperability interfaces, business-user data access APIs, consent and preference evidence, ranking and self-preferencing audit signals, advertising transparency evidence, app-store or marketplace access controls, anti-circumvention guardrails, observability, change control, documentation, and compliance evidence handoff.
The purpose of this Skill is to increase awareness of potential gaps in the system and create engineering evidence for qualified review. The response produced by this Skill does not represent legal advice, a legal opinion, a gatekeeper designation, a core platform service classification, or a final regulatory determination.
The main question is:
When does a Java enterprise platform require DMA-aware gatekeeper controls, and what should developers build differently?

What ships with it
3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

808-regulations-eu-digital-markets-act is a skill published in the GitHub repository jabrena/plinth (439 stars, last pushed yesterday), licensed Apache-2.0. It adds 122 tokens to every session and 2,296 once invoked, about $0.0006 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
