Eventyay is an open-source platform for managing events, including ticket sales and registration, speaker submissions, session schedules, videos, check-ins, badges, exhibitions, and organiser administration. Event organisers use it to run both in-person and online event workflows.
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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00095 | $0.00095 |
| Opus 5 | $0.00048 | $0.00048 |
| Sonnet 5 | $0.00019 | $0.00019 |
| Haiku 4.5 | $0.00010 | $0.00010 |
Grade A, and why
eventyay jinja.instructions.md 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 5d 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
Jinja Template Instructions
Formatting
- Prefer single quotes in template markup and expressions.
- Use different quote styles when nesting quotes inside expressions.
- Use 2-space indentation.
Template logic
- Keep templates focused on presentation. Move non-trivial business logic to Python views/forms/helpers.
- Avoid complex conditional chains inside HTML attributes. Compute values before rendering when possible.
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.
