cnil-cookie-bannerDesigning and implementing CNIL-compliant cookie consent banners for French and EU audiences.
Cnil Cookie Banner is an agent skill from mukul975/Privacy-Data-Protection-Skills. Designing and implementing CNIL-compliant cookie consent banners for French and EU audiences. References the EUR 100M Google LLC fine and EUR 150M Meta Platforms fine for non-compliant cookie practices. Covers equal prominence, reject-all buttons, cookie walls prohibition, and 6-month reconsent cycles.
Its SKILL.md is about 2.8k tokens, which your agent loads only when the skill is triggered. The skill folder holds 7 other files, including scripts, reference files and assets (for example `assets/template.md`, `references/standards.md` and `references/workflows.md`).
It sits in Legal & Compliance, covering Privacy and GDPR. The repository describes itself as: 282+ structured privacy & data protection skills for AI agents. GDPR, CCPA, EU AI Act, HIPAA, LGPD, PIPL, DPDP Act. The licence is Apache-2.0.
5 steps, taken from the step headings in SKILL.md.
Read from SKILL.md and the folder at commit 9b2ef9e. It shows what the files ask for, not the result of running them.
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.
Ships 1 file in scripts/ (Python), which the agent can run.
From the folder's file list and the shell code blocks in SKILL.md.
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Cnil Cookie Banner loads about 2.8k tokens when it runs, and up to ~4.2k if it reads all its reference files. Until then it costs about 81 tokens; SKILL.md has 887 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.
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.

This skill also uses 4 other files; get the full folder from GitHub.The Commission Nationale de l'Informatique et des Libertés (CNIL) enforces some of the strictest cookie consent requirements in the EU. Following its updated guidelines (Deliberation No. 2020-091 of 17 September 2020) and landmark enforcement actions — including the EUR 100 million fine against Google LLC and EUR 50 million against Google Ireland Limited (31 December 2021), and the EUR 60 million fine against Meta Platforms Ireland Limited (31 December 2022, later increased in subsequent actions totaling EUR 150 million across multiple decisions) — organizations serving French users must implement cookie banners meeting specific design and functional requirements.
The CNIL requires that the mechanism to refuse cookies must be as easy to use as the mechanism to accept them. This was the central issue in the Google and Meta enforcement actions — both companies provided a prominent "Accept All" button but required multiple clicks to reject cookies.

Prohibited Implementation:

CNIL recommends that consent be renewed at regular intervals:
| Parameter | CNIL Requirement |
|---|---|
| Maximum consent validity | 6 months (CNIL recommendation) |
| Refusal retention | 6 months before re-prompting |
| Consent proof retention | Duration of consent + applicable statute of limitations |
| Re-prompt after consent expiry | Banner must reappear automatically |
| Re-prompt after cookie policy change | Mandatory — new consent required |
Implementation for Pinnacle E-Commerce Ltd:
Store the consent timestamp in a first-party cookie:
cookie_consent_timestamp=2026-01-15T10:30:00Z
cookie_consent_version=v2.3
cookie_consent_state=accepted_analytics|rejected_advertising|accepted_functionalityOn each page load, check:
cookie_consent_timestamp exist?cookie_consent_version match the current cookie policy version?If any check fails, redisplay the banner.
CNIL specifically prohibits the following dark patterns:
| Dark Pattern | Description | Why Prohibited |
|---|---|---|
| Asymmetric buttons | Accept is large/colorful, reject is small/grey | Unequal prominence violates equal ease requirement |
| Hidden reject | Reject option buried in settings layers | Must be at same level as accept |
| Confusing toggles | Toggle visually suggests ON when it is OFF | Undermines informed consent |
| Guilt-tripping | "By rejecting, you'll miss personalised offers" | Manipulative language |
| Pre-selected purposes | Analytics or functionality toggles pre-enabled | Violates active consent requirement (Planet49) |
| Repeated prompting | Re-showing banner on every page after rejection | Coercion; must respect refusal for 6 months |

Designing and implementing CNIL-compliant cookie consent banners for French and EU audiences. Cnil Cookie Banner is an agent skill from mukul975/Privacy-Data-Protection-Skills. Designing and implementing CNIL-compliant cookie consent banners for French and EU audiences.
Cnil Cookie Banner fits situations like: tasks that involve Privacy and GDPR.
Run `npx skills add mukul975/Privacy-Data-Protection-Skills --skill cnil-cookie-banner -a claude-code`. Or copy the skill folder (skills/privacy/cnil-cookie-banner in mukul975/Privacy-Data-Protection-Skills) into .claude/skills/cnil-cookie-banner in your project. Claude Code loads it when a task matches its description.
Run `npx skills add mukul975/Privacy-Data-Protection-Skills --skill cnil-cookie-banner -a codex`. Or copy the skill folder (skills/privacy/cnil-cookie-banner in mukul975/Privacy-Data-Protection-Skills) into .agents/skills/cnil-cookie-banner in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add mukul975/Privacy-Data-Protection-Skills --skill cnil-cookie-banner -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/cnil-cookie-banner, .gemini/skills/cnil-cookie-banner, .github/skills/cnil-cookie-banner and .opencode/skills/cnil-cookie-banner in your project.
Going by SKILL.md and its folder, Cnil Cookie Banner needs Python for the scripts in its folder. Our summary lists: Python 3.
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
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.
Cnil Cookie Banner is published under the Apache-2.0 licence (declared in SKILL.md). It allows redistribution, so the full SKILL.md is shown on this page.
About 2.8k tokens (SKILL.md is roughly 11k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 1.5k tokens, read only when the agent opens those files.
Skills that share tags, products or a category with Cnil Cookie Banner: C15t (c15t/c15t, 1.9k stars), HIPAA Safe Harbor Coverage Audit (maziyarpanahi/openmed, 5.5k stars), Korean Privacy Terms (kimlawtech/korean-privacy-terms, 587 stars) and Gdpr Compliance (Sushegaad/Claude-Skills-Governance-Risk-and-Compliance, 946 stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
