System Prompts Leaks is a collection of captured system instructions used to guide AI chatbots and coding agents before they receive user messages. It serves researchers and developers studying how different AI assistants are directed.
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.

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 | $0.00028 | $0.02354 |
| Opus 5.5 | $0.00011 | $0.00942 |
| Sonnet 5.5 | $0.00006 | $0.00471 |
| Haiku 4.5 | $0.00003 | $0.00235 |
Grade A, and why
ticketmaster 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 16d 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.

Ticketmaster
Purpose
Search events and get smart Ticketmaster seat recommendations.
For a user-facing event-ticket search or purchase, first read
/opt/hatch/skills/booking/SKILL.md,
/opt/hatch/skills/booking/references/tickets.md, and
/opt/hatch/skills/booking/references/presentation.md. Those files define the
routing, presentation, browser checkout, and commitment rules. Use this file
for the Ticketmaster CLI contract. Do not call seat-view-carousel, create
HTML, or use widget.create for a booking flow. Use the compact Markdown ticket
table and optional verified Markdown images.
Do not call create_options for ticket choices or checkout decisions.
Tooling
ticketmaster <subcommand> [options]
search-events
Search for events by keyword (required), location, and date range. Supports --country-code (default: US), --page (0-indexed), and --sort (e.g. date,asc, relevance,desc, name,asc). --start-date and --end-date accept ISO 8601 values; bare YYYY-MM-DD dates are normalized by the CLI.
ticketmaster search-events --keyword "Taylor Swift" --city "Los Angeles" --size 10
ticketmaster search-events --keyword "Lakers" --start-date 2026-05-01 --end-date 2026-06-01 --state-code CA --sort date,asc
event-details
Get full details for a specific event ID returned by search-events.
ticketmaster event-details --event-id vvG1IZ_AKnSEae
top-picks
Get seat recommendations sorted by price or quality. Default --selection Any returns Standard + Resale + Platinum tickets. Use --selection Standard to exclude resale. Returns venue_map_url and per-pick snapshot_image_url when available. Preserve those URLs for verified Markdown links or images.

What ships with it
1 file 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.
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.
