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 | $0.00022 | $0.00821 |
| Opus 5.5 | $0.00009 | $0.00328 |
| Sonnet 5.5 | $0.00004 | $0.00164 |
| Haiku 4.5 | $0.00002 | $0.00082 |
Grade A, and why
printify 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.

Printify (Print on Demand)
Purpose
Use the printify CLI to manage shops, products, uploads, orders, and catalog lookups.
Tooling
Use the installed CLI directly from PATH:
printify <subcommand> [options]
Global flags:
--timeout-secs <seconds>(optional, default 30): HTTP timeout.
Core commands:
statusauthorize-urlverifyset-token(reads token from stdin)disconnectshopsproducts --shop-id <id> [--product-id <id>]create-product --shop-id <id> --json '<json>'update-product --shop-id <id> --product-id <id> --json '<json>'delete-product --shop-id <id> --product-id <id>publish-product --shop-id <id> --product-id <id>orders --shop-id <id> [--order-id <id>]create-order --shop-id <id> --json '<json>'upload --file <path>blueprints [--blueprint-id <id>]print-providers --blueprint-id <id>variants --blueprint-id <id> --provider-id <id>shipping --blueprint-id <id> --provider-id <id>

Auth
First-use setup:
- Run
printify statusto check connection state. - If not connected and
connect_urlis present, replace<connect_url>with the returned URL and share exactly this Markdown link:[Connect Printify](<connect_url>); do not paste the raw URL separately. - If
connect_urlis missing, runprintify authorize-urland share the returnedconnect_urlthe same way. - The user can generate a token at
https://printify.com/app/account/api. - If the user provides a token through the CLI flow, store it only through
printify set-token; do not write auth files directly. - Run
printify verifyafter setup when you need to confirm the token works. - Never print the access token in chat output.
What ships with it
2 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.
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.
