At a glance

Build the Convex project from source. An agent skill from Convex-Dev/convex.

  • A contributor wants to compile
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Build Convex is an agent skill from Convex-Dev/convex. Build the Convex project from source. Use when a contributor wants to compile, test, or package Convex.

Its SKILL.md is about 140 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files (for example `agents/openai.yaml`).

The repository describes itself as: Convex Main Repository - Decentralised platform for the Internet of Value.

When your agent uses it

  • A contributor wants to compile

Example prompts

  • “/build-convex”

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

Build Convex loads about 139 tokens when it runs. Until then it costs about 29 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
~29
When it runs · the whole SKILL.md, loaded when a task matches
~139

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 (~139 tokens).

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