A lookup guide for finding current, practical information about a bouldering or climbing gym, such as hours, prices, location, facilities, and training details.

Use it to check one gym or compare several gyms, including opening hours, day passes, multi-entry passes, partner memberships, transport, lockers, equipment, routes, and training options.

Gym information is often spread across several pages and changes over time. It helps gather the relevant details from authoritative sources and present them clearly.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00110	$0.02469
Opus 5.5	$0.00044	$0.00988

Security

Grade A, and why

boulder-gym 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 2mo 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.

How it starts

The opening of the file, as written. The whole thing — 120 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Look up real, current info about a bouldering (or climbing) gym and report it back in a clean, scannable format. Works for any gym worldwide; defaults are tuned for Germany (Munich / Berlin), since most sites are in German.

1. Parse the request

Gym name — required (e.g. "Boulderwelt West", "BK Kreuzberg", "Der Kegel").
City — if not given, assume Munich. Many chains have multiple locations (Boulderwelt Ost/West/Süd, Einstein, DAV Kletterzentrum), so if the name is ambiguous, either use the city to disambiguate or briefly ask which branch.
Multiple gyms → produce a comparison table (see §5), not separate reports.
Specific question ("is Boulderwelt West open now?", "does Der Kegel take Wellpass?") → answer that first and directly, then offer the full rundown.

2. Find the authoritative source

Prices, hours, and partner deals change constantly — always verify live, never answer from memory.

WebSearch for the official site: <gym> <city> bouldern öffnungszeiten preise.
WebFetch the homepage, then follow to the pages that actually hold the data. German gyms usually split it across:
- Preise / Tarife / Eintritt → prices, 10-pass, subscriptions, discounts
- Öffnungszeiten / Kontakt → hours & address
- Anfahrt / Anreise / Parken → parking, bike parking, transit (often a page separate from Kontakt)
- FAQ / Infos / Erstbesuch / Gut zu wissen → lockers, rental, waiver, rules
- Anlage / Halle / Über uns → wall size, boulder count, training area
Parking fallback: if the Kontakt page doesn't mention parking, check the Anfahrt/Anreise page and the FAQ before reporting "not listed" — it's usually documented somewhere.
Live occupancy: many gyms publish a real-time capacity tracker (Auslastung / Ampel / "Wie voll ist es?") — check the homepage and for a dedicated page/widget. If there's none, note that they post capacity updates on Instagram (link the handle) so a fanatic can still gauge the crowd.
If the site is JS-heavy and WebFetch returns little, fall back to Claude-in-Chrome (navigate + read_page) to render it — the live-occupancy widget in particular is often JS-rendered.
Cross-check hours against the Google Business listing (search <gym> <city> opening hours) — it often shows "open now / closes at" and holiday hours the site omits.

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.
