What it does
Babashka is an agent skill from PEZ/epupp. Babashka scripting conventions for the Epupp project. Use when: writing or modifying bb.edn tasks, scripts in scripts/, build or test automation, choosing between bb and npx/npm/shell/Python, using babashka.fs, babashka.process, or babashka.http-client, or running any bb command in this repo. Prefer bb tasks over direct npm/npx; keep bb.edn minimal and put code in scripts/tasks.clj. IMPORTANT: Also load when planning automation or build pipeline changes.
Its SKILL.md is about 360 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 DevOps & Cloud, covering CI/CD. It works with Python and npm. The repository describes itself as: A web browser extension that lets you tamper with web pages, live and/or with userscripts. The licence is MIT.
When your agent uses it
- Modifying bb.edn tasks
- Scripts in scripts/
- Test automation
- Choosing between bb and npx/npm/shell/Python
Example prompts
- “/babashka”
Requirements
- Python 3
What it can do on your machine
Read from SKILL.md and the folder at commit 566ce34. 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:
python
From the folder's file list and the shell code blocks in SKILL.md.
Network
Links to these hosts (documentation or services it may open):
github.com
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
Babashka loads about 360 tokens when it runs. Until then it costs about 117 tokens; SKILL.md has 121 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

- description
- Babashka scripting conventions for the Epupp project. Use when: writing or modifying bb.edn tasks, scripts in scripts/, build or test automation, choosing between bb and npx/npm/shell/Python, using babashka.fs, babashka.process, or babashka.http-client, or running any bb command in this repo. Prefer bb tasks over direct npm/npx; keep bb.edn minimal and put code in scripts/tasks.clj. IMPORTANT: Also load when planning automation or build pipeline changes.
Using Babashka in This Project
This project uses Babashka, a fast-starting Clojure interpreter for scripting and automation.
bb Tasks
Don't put anything but the minimum code snippets in bb.edn. Use scripts/tasks.clj for code and call them from bb tasks.
Babashka utilities
Prefer Babashka built-in utilities over Python, shell scripts, or other external tools when functionality overlaps. The project uses Babashka extensively and has dependencies loaded.
Common replacements:
- HTTP server: Use
bb test:serverorbabashka.http-serverinstead ofpython -m http.server - File operations: Use
babashka.fsinstead of shell commands (cp, mv, rm, find, etc.) - Process execution: Use
babashka.processinstead of raw shell scripts - HTTP requests: Use
babashka.http-clientinstead of curl or wget
Check bb.edn dependencies and existing tasks before reaching for external tools.
