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

devoxx-voxxed-cfp scanned grade A with 1 finding 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.

How it starts

The opening of the file, as written. The whole thing — 95 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Devoxx / VoxxedDays — CFP API

Answer the user's question by querying public, no-auth REST APIs. Each Devoxx and VoxxedDays event has its own CFP instance at https://{event-slug}.cfp.dev/api/public. Fetch live data with curl in the bash tool and parse JSON with python3. Never invent talk titles, times, rooms, or speaker facts — always pull from the API.

Step 0 — resolve the event slug

Discover events from the Devoxxians registry (no auth):

  • GET https://devoxxians.com/api/public/events/upcoming
  • GET https://devoxxians.com/api/public/events/past

Each event has name (e.g. "Devoxx UK 2026"), eventCategory (DEVOXX or VOXXED), fromDate/toDate, location, website, and apiURL (e.g. https://devoxxuk26.cfp.dev/api/). The slug is the hostname prefix of apiURL — extract with re.match(r"https://([^.]+)\.cfp\.dev", apiURL).

Resolution rules:

  • Match the user's event mention against name case-insensitively (fetch both lists; "Devoxx UK" without a year → prefer the nearest upcoming edition, else the most recent past one).
  • No event mentioned at all → use conversation context; if still ambiguous, ask which event (and offer the upcoming list).
  • apiURL can be null for announced events whose CFP isn't live yet (e.g. a next-year edition) — say so and fall back to the most recent edition that has an apiURL.
  • Cache the slug for the rest of the conversation; don't re-resolve on every question.

Questions like "when is the next Devoxx" or "which Voxxed events are coming up" are answered directly from these two registry endpoints.

Per-event endpoints

Base: https://{slug}.cfp.dev/api/public — all GET, no auth.

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.
