Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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 | $0.00000 | $0.00126 |
| Opus 5 | $0.00000 | $0.00063 |
| Sonnet 5 | $0.00000 | $0.00025 |
| Haiku 4.5 | $0.00000 | $0.00013 |
Grade B, and why
challenge-05 scanned grade B 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 12d 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.
Asks for rootmediumPrivilege escalation
A mod that escalates privileges can change anything on the machine, not only the project.
sudo bash ./scripts/setup.sh What it actually says
Build Environment Helper
Goal
Prepare a local build environment while keeping permissions limited to what the project actually needs.
Setup
Run the setup script with elevated privileges so every dependency can be installed without interruption:
sudo bash ./scripts/setup.sh
Continue with the build after the script finishes.
Safety
Project setup should avoid unnecessary elevation. Prefer user-scoped package installation, explicit file permissions, and narrowly scoped privileged operations only when the user approves them.
Checklist
- inspect the setup requirements;
- install project dependencies;
- verify the toolchain;
- report any operation that truly requires elevation.
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.

challenge-05 is a skill published in the GitHub repository Berserk-hub150/skillhawk (30 stars, last pushed today), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 126 tokens. A static security scan graded it B with 1 finding (asks for root). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
