What it does
Test Quality is an agent skill from cataclysmbn/Cataclysm-BN. Write or review Cataclysm-BN tests that avoid flakes, use deterministic fixtures, and clean up global state.
Its SKILL.md is about 490 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 Testing & QA, covering State management. The repository describes itself as: Cataclysm: Bright Nights: A fork/variant of Cataclysm:DDA by CleverRaven with a mod registry at https://mods.cataclysmbn.org/.
When your agent uses it
- Tasks that involve State management
Example prompts
- “/test-quality”
What it can do on your machine
Read from SKILL.md and the folder at commit a27f19d. 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
Test Quality loads about 490 tokens when it runs. Until then it costs about 30 tokens; SKILL.md has 254 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 254 words (~490 tokens).
“Use when adding or changing automated tests.”
