What it does
Debugging Gnollhack is an agent skill from hyvanmielenpelit/GnollHack. Instructions on how to use wizard mode (debug mode), decipher panic logs, test specific levels/monsters, and run the MAUI frontend locally.
Its SKILL.md is about 140 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Development, covering Cross-platform mobile apps and Debugging. The repository describes itself as: Modern evolution of the classic roguelike game NetHack.
When your agent uses it
- Tasks that involve Cross-platform mobile apps
- Tasks that involve Debugging
Example prompts
- “Use the debugging-gnollhack skill to instruction on how to use wizard mode (debug mode), decipher panic logs, test specific levels/monsters, and run…”
- “/debugging-gnollhack”
What it can do on your machine
Read from SKILL.md and the folder at commit 9df8a69. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Debugging Gnollhack loads about 138 tokens when it runs. Until then it costs about 40 tokens; SKILL.md has 51 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
SKILL.md
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 51 words (~138 tokens).
“The full skill lives in this repository's tool-neutral agent directory (.agents/), which is shared with other AI coding agents. This file is only a pointer.”
