This is fossasia/eventyay's own configuration. It tells Claude Code and Codex how to work on eventyay itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything eventyay configures →

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.

Security

Grade A, and why

frontend-ui 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.

What it actually says

Skill: Frontend UI

When to Use

Use this skill when implementing or modifying UI behavior in:

  • app/eventyay/static/ assets
  • app/eventyay/webapp/ Vue applications
  • Django templates under app/eventyay/**/templates/

Core Workflow

  1. Identify whether the change belongs to legacy static assets or a Vue app.
  2. Keep behavior in external scripts (no inline JS; no jQuery).
  3. Ensure responsive behavior across common mobile and desktop widths.
  4. Validate accessibility basics: labels, keyboard navigation, focus visibility, and semantic landmarks.
  5. Add or update tests when UI behavior changes are user-visible.

Guardrails

  • Follow .github/instructions/js.instructions.md for JS/Vue conventions.
  • Follow .github/instructions/django-template.instructions.md for template conventions.
  • Preserve existing design language unless the task explicitly requests a redesign.

Supporting Artifacts

  • Implementation references: references/
  • Reusable templates/checklists: assets/
  • Example validation scenarios: tests/
Files

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.

Changes

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.
