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.

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 | $0.00073 | $0.01926 |
| Opus 5 | $0.00036 | $0.00963 |
| Sonnet 5 | $0.00015 | $0.00385 |
| Haiku 4.5 | $0.00007 | $0.00193 |
Grade A, and why
global-privacy-control 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 13d 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.

Implementing Global Privacy Control (GPC)
Overview
Global Privacy Control (GPC) is a browser-level signal that communicates a user's privacy preference to opt out of the sale or sharing of their personal information. The GPC specification defines both an HTTP header (Sec-GPC: 1) and a JavaScript API (navigator.globalPrivacyControl) for transmitting this signal.
Under California Privacy Rights Act (CPRA) Section 1798.135(e), businesses must treat GPC signals as valid opt-out requests. The California Attorney General confirmed this enforcement position in the Sephora settlement (August 2022, $1.2 million fine), which was the first enforcement action involving GPC signals.
Legal Requirements by State
California — CPRA (effective January 1, 2023)
- Section 1798.135(e): A business that collects consumers' personal information shall treat the consumer's use of an opt-out preference signal as a valid request to opt out of sale/sharing under Section 1798.120.
- AG Regulation 11 CCR 7025(b): If a business collects personal information from consumers online, the business shall treat an opt-out preference signal as a valid request to opt-out of sale/sharing for that browser or device and any consumer profile associated with that browser or device.
- Sephora Settlement (August 2022): California AG fined Sephora $1.2 million for failing to honor GPC signals, among other violations.
Colorado — Colorado Privacy Act (CPA, effective July 1, 2024)
- Section 6-1-1306(1)(a)(IV)(A): Consumers may exercise the right to opt out through an opt-out preference signal sent by a platform, technology, or mechanism on behalf of the consumer, to the extent technically feasible.
- CPA Rules 4.6: Controllers must recognize universal opt-out mechanisms by July 1, 2024.
Connecticut — Connecticut Data Privacy Act (CTDPA, effective July 1, 2023)
- Section 42-520(b)(5): Beginning January 1, 2025, controllers must recognize universal opt-out mechanisms for the sale of personal data and targeted advertising.
What ships with it
4 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.
