Project scope by default; add --scope user for a personal install. Needs GitHub CLI 2.90.0 or later (public preview).

Manual copy
$ git clone --depth 1 https://github.com/Convex-Dev/convex.git skills-src && mkdir -p .claude/skills && cp -r skills-src/.agents/skills/convex-lisp .claude/skills/convex-lisp && rm -rf skills-src

At a glance

Convex Lisp language reference — CVM conventions, calling library code, actor definitions, juice and error codes.

  • Debugging CVM source for queries
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Convex Lisp is an agent skill from Convex-Dev/convex. Convex Lisp language reference — CVM conventions, calling library code, actor definitions, juice and error codes. Use when writing or debugging CVM source for queries, transactions or actors.

Its SKILL.md is about 160 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. The repository describes itself as: Convex Main Repository - Decentralised platform for the Internet of Value.

When your agent uses it

  • Debugging CVM source for queries

Example prompts

  • “/convex-lisp”

What it can do on your machine

Read from SKILL.md and the folder at commit 0fec9b9. 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

Convex Lisp loads about 161 tokens when it runs. Until then it costs about 51 tokens; SKILL.md has 48 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~51
When it runs · the whole SKILL.md, loaded when a task matches
~161

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 (~161 tokens).

“This is the Codex discovery entry for the canonical shared skill at .claude/skills/convex-lisp/SKILL.md.”

How do I install Convex Lisp in Claude Code?

Run `npx skills add Convex-Dev/convex --skill convex-lisp -a claude-code`. Or copy the skill folder (.agents/skills/convex-lisp in Convex-Dev/convex) into .claude/skills/convex-lisp in your project. Claude Code loads it when a task matches its description.

How do I install Convex Lisp in Codex?

Can I use Convex Lisp 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 convex-lisp -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/convex-lisp, .gemini/skills/convex-lisp, .github/skills/convex-lisp and .opencode/skills/convex-lisp in your project.

What does Convex Lisp need to run?

SKILL.md names no scripts, command-line tools or credentials: Convex Lisp is instructions for the agent only.

Does Convex Lisp 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.

Convex Lisp 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 Convex Lisp use?

About 161 tokens (SKILL.md is roughly 644 characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
