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 | $0.00050 | $0.00314 |
| Opus 5.5 | $0.00020 | $0.00126 |
| Sonnet 5.5 | $0.00010 | $0.00063 |
| Haiku 4.5 | $0.00005 | $0.00031 |
Grade A, and why
asana 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 19d 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
Asana
Use the installed asana CLI. Start with asana status. If it reports
not_connected, run asana authorize-url and share only the returned
connect_url with the user.
OAuth uses the fixed Muse Asana MCP app, PKCE, and Asana's MCP resource indicator through authd. CAGI supplies the client secret for token exchange, refresh, and revocation; the secret must never enter Muse or be requested in chat. Do not request ordinary Asana API scopes because MCP apps reject them.
Run asana list-tools to inspect the live provider catalogue and schemas,
then call an advertised tool with:
asana call-tool --name <tool> --arguments-json '<json-object>'
list-tools exposes only reviewed Asana tools and includes each tool's
hatch_permission, hatch_action, and hatch_permission_label. Unknown or
new provider tools remain unavailable until reviewed. Read permissions follow
the user's connector settings; changes require the corresponding granular
approval. Do not retry a failed or timed-out write automatically because its
side effect may have completed.
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.

asana is a skill published in the GitHub repository asgeirtj/system_prompts_leaks (70,113 stars, last pushed yesterday), licensed CC0-1.0. It adds 50 tokens to every session and 314 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-10-05.
