What it does
Starship Config is an agent skill from wcygan/dotfiles. Configure and optimize Starship cross-shell prompt with presets, custom modules, and performance tuning. Use when setting up Starship, creating prompt configs, customizing prompt appearance, or troubleshooting prompt issues. Keywords: starship, prompt, shell prompt, PS1, starship.toml, preset, prompt config, shell theme
Its SKILL.md is about 1.5k tokens, which your agent loads only when the skill is triggered. The skill folder holds 8 other files, including scripts (for example `REFERENCE.md`, `scripts/apply-preset.sh` and `scripts/test-config.sh`).
It sits in Agent Workflows. It works with Git. The repository describes itself as: Configuration for Development Environments.
When your agent uses it
- Setting up Starship
- Creating prompt configs
- Customizing prompt appearance
- Troubleshooting prompt issues
Example prompts
- “/starship-config”
Requirements
- Node.js
- A Bash shell
- Docker

What it can do on your machine
Read from SKILL.md and the folder at commit 3386d8c. 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
Ships 2 files in scripts/ (Shell), which the agent can run.
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):
starship.rs
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
Starship Config loads about 1.5k tokens when it runs. Until then it costs about 84 tokens; SKILL.md has 371 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); the scripts in this folder are not scanned.
SKILL.md
Without a licence we can't republish the file, so here is its outline and opening line. It has 371 words (~1,525 tokens).
“Manages complete Starship prompt configuration lifecycle including setup, customization, and optimization.”
