What it does
Juice is an agent skill from Convex-Dev/convex. Juice accounting — the cost of computation and bandwidth on the CVM. Use when reasoning about transaction execution cost, diagnosing a :JUICE failure, or pricing a new CVM operation.
Its SKILL.md is about 150 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 Business, Finance & HR, covering Accounting and bookkeeping. The repository describes itself as: Convex Main Repository - Decentralised platform for the Internet of Value.
When your agent uses it
- Reasoning about transaction execution cost
- Diagnosing a :JUICE failure
- Pricing a new CVM operation
Example prompts
- “/juice”
What it can do on your machine
Read from SKILL.md and the folder at commit 9e199a3. 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.
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
Juice loads about 154 tokens when it runs. Until then it costs about 47 tokens; SKILL.md has 48 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 48 words (~154 tokens).
“This is the Codex discovery entry for the canonical shared skill at .claude/skills/juice/SKILL.md.”

How do I install Juice in Claude Code?
Run `npx skills add Convex-Dev/convex --skill juice -a claude-code`. Or copy the skill folder (.agents/skills/juice in Convex-Dev/convex) into .claude/skills/juice in your project. Claude Code loads it when a task matches its description.
How do I install Juice in Codex?
Run `npx skills add Convex-Dev/convex --skill juice -a codex`. Or copy the skill folder (.agents/skills/juice in Convex-Dev/convex) into .agents/skills/juice in your project. Codex loads it when a task matches its description.
Can I use Juice 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 Convex-Dev/convex --skill juice -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/juice, .gemini/skills/juice, .github/skills/juice and .opencode/skills/juice in your project.
What does Juice need to run?
SKILL.md names no scripts, command-line tools or credentials: Juice is instructions for the agent only.
Does Juice 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 Juice safe to install?

What licence does Juice use?
Juice has a licence file (the repository's licence) that doesn't match a standard licence. Read it on GitHub before reusing the skill.
How many tokens does Juice use?
About 154 tokens (SKILL.md is roughly 616 characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
What are the alternatives to Juice?
Skills that share tags, products or a category with Juice: Sync Upstream (nyaruka/phonenumbers, 1.6k stars), Longbridge Value Investing (helsome/folio, 269 stars), Radiology Table (huang-sir1/radiology-skills, 1.9k stars) and Odoo Agency Fleet Review (erpipe-org/mcp-odoo, 419 stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
Who maintains Juice?
Convex-Dev (a GitHub organization) maintains it in Convex-Dev/convex, which has 117 GitHub stars. The repository holds 12 skills in this directory. The repository was last updated on October 6, 2026.
