What it does
Using Common Lisp Repl is an agent skill from ultralisp/ultralisp. Use when developing Common Lisp interactively against a running image reachable through an MCP eval tool (evallispform / eval-lisp-form) and you need to evaluate forms safely, reload a file after editing it, capture REPL output, or locate a dependency's sources on disk.
Its SKILL.md is about 1.3k 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 Model Context Protocol. The repository describes itself as: The software behind a Ultralisp.org Common Lisp repository.
When your agent uses it
- Reload a file after editing it
- Capture REPL output
- Locate a dependencys sources on disk
Example prompts
- “/using-common-lisp-repl”
What it can do on your machine
Read from SKILL.md and the folder at commit 3439788. 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 lisp).
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
Using Common Lisp Repl loads about 1.3k tokens when it runs. Until then it costs about 74 tokens; SKILL.md has 577 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
Without a licence we can't republish the file, so here is its outline and opening line. It has 577 words (~1,332 tokens).
“When the project has a running Lisp image reachable through an MCP eval tool (eval_lisp_form / eval-lisp-form), prefer evaluating forms in that live image over shelling out to a fresh sbcl. This keeps shared state intact: loaded systems, in-memory data…”

Using Common Lisp Repl is an agent skill from ultralisp/ultralisp. Use when developing Common Lisp interactively against a running image reachable through an MCP eval tool (evallispform / eval-lisp-form) and you need to evaluate forms safely, reload a file after editing it, capture REPL output, or locate a dependency's sources on disk.
When should I use Using Common Lisp Repl?
Using Common Lisp Repl fits situations like: reload a file after editing it; capture REPL output; locate a dependencys sources on disk.
How do I install Using Common Lisp Repl in Claude Code?
Run `npx skills add ultralisp/ultralisp --skill using-common-lisp-repl -a claude-code`. Or copy the skill folder (.agents/skills/using-common-lisp-repl in ultralisp/ultralisp) into .claude/skills/using-common-lisp-repl in your project. Claude Code loads it when a task matches its description.
