What it does
Terminal Output is an agent skill from swamp-club/swamp. Terminal output design system for swamp CLI commands. Use when creating or modifying any CLI command output, render function, or presentation layer code. Ensures consistent formatting, coloring, and structure across all swamp commands in both "log" (human-readable) and "json" (structured) output modes. Triggers on output files in src/presentation/output/, render functions, writeOutput usage, OutputMode handling, or any CLI command that produces terminal output.
Its SKILL.md is about 2.1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/logtape.md`).
It sits in AI & LLM Engineering, covering Structured output and tool calling and Design systems. The repository describes itself as: Stinemates, Watson, Adam, Mahir, Paul.
When your agent uses it
- Modifying any CLI command output
- Render function
- Presentation layer code
- Output files in src/presentation/output/
Example prompts
- “(human-readable) and”
- “/terminal-output”
Workflow steps
2 steps, taken from the first numbered list in SKILL.md.
- A data interface describing the output shape
- A render function that branches on OutputMode
What it can do on your machine
Read from SKILL.md and the folder at commit 1b5a295. 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 (its code samples are typescript).
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
Terminal Output loads about 2.1k tokens when it runs, and up to ~4.4k if it reads all its reference files. Until then it costs about 120 tokens; SKILL.md has 682 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 682 words (~2,082 tokens).
“Consistent, human-readable terminal output for the swamp CLI.”
