What it does
Deno Script is an agent skill from cataclysmbn/Cataclysm-BN. Write or modify Cataclysm-BN Deno/TypeScript scripts. Use for scripts, tools, migrations, generators, git hooks, and CLI utilities.
Its SKILL.md is about 1.8k 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. It works with Deno, Git and TypeScript. 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
- Development work in your project
Example prompts
- “/deno-script”
Workflow steps
9 steps, taken from the step headings in SKILL.md.
- Shebang and Permissions

What it can do on your machine
Read from SKILL.md and the folder at commit 165eead. 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
Shell commands in SKILL.md call:
deno
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
Deno Script loads about 1.8k tokens when it runs. Until then it costs about 36 tokens; SKILL.md has 429 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 429 words (~1,767 tokens).
“Write Deno/TypeScript scripts following Cataclysm: Bright Nights conventions.”
