What it does
Luna is an agent skill from mizchi/luna.mbt. Use whenever working with mizchi/luna in the luna.mbt repo — writing CSR examples, fixing reactivity bugs (effects re-running on unrelated signal changes), adding new luna features, or onboarding to luna's mental model. This is the unified entry point; pick the right reference page below for the specific situation.
Its SKILL.md is about 900 tokens, which your agent loads only when the skill is triggered. The skill folder holds 3 other files, including reference files (for example `references/csr-app-scaffolding.md` and `references/signal-tracking.md`).
It sits in Development. The repository describes itself as: Experimental: Declarative UI Framework for Moonbit.
When your agent uses it
- Working with mizchi/luna in the luna.mbt repo — writing CSR examples
- Fixing reactivity bugs (effects re-running on unrelated signal changes)
- Adding new luna features
- Onboarding to lunas mental model
Example prompts
- “/luna”
Workflow steps
3 steps, taken from the step headings in SKILL.md.
- orient (only on first encounter)
- pick the reference page
- verify before claiming done
What it can do on your machine
Read from SKILL.md and the folder at commit 874f0f3. 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:
pnpmnode
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use pnpm, which can reach the network depending on how they are called.
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
Luna loads about 897 tokens when it runs, and up to ~5.1k if it reads all its reference files. Until then it costs about 81 tokens; SKILL.md has 402 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 402 words (~897 tokens).
“mizchi/luna is the fine-grained reactive UI primitive that sits under sol and astra. It's small in surface but easy to misuse in two specific ways (reactivity tracking, example-pipeline registration) that have already burned real time in this repo. This skill…”

Questions about Luna
What does Luna do?
A skill your agent uses whenever working with mizchi/luna in the luna.mbt repo — writing CSR examples, fixing reactivity bugs (effects re-running on unrelated signal changes), adding new luna…. mbt.mbt repo — writing CSR examples, fixing reactivity bugs (effects re-running on unrelated signal changes), adding new luna features, or onboarding to luna's mental model.
When should I use Luna?
Luna fits situations like: working with mizchi/luna in the luna.mbt repo — writing CSR examples; fixing reactivity bugs (effects re-running on unrelated signal changes); adding new luna features; onboarding to lunas mental model.
How do I install Luna in Claude Code?
Run `npx skills add mizchi/luna.mbt --skill luna -a claude-code`. Or copy the skill folder (.claude/skills/luna in mizchi/luna.mbt) into .claude/skills/luna in your project. Claude Code loads it when a task matches its description.
How do I install Luna in Codex?
Run `npx skills add mizchi/luna.mbt --skill luna -a codex`. Or copy the skill folder (.claude/skills/luna in mizchi/luna.mbt) into .agents/skills/luna in your project. Codex loads it when a task matches its description.
Can I use Luna in Cursor, Gemini CLI or GitHub Copilot?
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add mizchi/luna.mbt --skill luna -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/luna, .gemini/skills/luna, .github/skills/luna and .opencode/skills/luna in your project.
What does Luna need to run?
Going by SKILL.md and its folder, Luna needs the command-line tools its instructions call (pnpm and node).
Does Luna access the network?
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Is Luna safe to install?
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
What licence does Luna use?
No licence was found for Luna or its repository. Without one, default copyright applies: ask the author before reusing or redistributing it.
How many tokens does Luna use?
About 897 tokens (SKILL.md is roughly 3.6k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 4.2k tokens, read only when the agent opens those files.
