At a glance
Use Convex DB — a lattice-backed SQL database. An agent skill from Convex-Dev/convex.
- Helping users write queries
- Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md
- Connect via JDBC
- PostgreSQL clients
What it does
Convex DB is an agent skill from Convex-Dev/convex. Use Convex DB — a lattice-backed SQL database. Use when helping users write queries, connect via JDBC or PostgreSQL clients, create tables, insert/query data, or use the direct lattice API.
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 Databases, covering SQL. It works with PostgreSQL and SQL. The repository describes itself as: Convex Main Repository - Decentralised platform for the Internet of Value.
When your agent uses it
- Helping users write queries
- Connect via JDBC
- PostgreSQL clients
- Insert/query data
Example prompts
- “/convex-db”
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
Convex DB loads about 159 tokens when it runs. Until then it costs about 50 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 (~159 tokens).
“This is the Codex discovery entry for the canonical shared skill at .claude/skills/convex-db/SKILL.md.”

When should I use Convex DB?
Convex DB fits situations like: helping users write queries; connect via JDBC; postgreSQL clients; insert/query data.
How do I install Convex DB in Claude Code?
Run `npx skills add Convex-Dev/convex --skill convex-db -a claude-code`. Or copy the skill folder (.agents/skills/convex-db in Convex-Dev/convex) into .claude/skills/convex-db in your project. Claude Code loads it when a task matches its description.
How do I install Convex DB in Codex?
Run `npx skills add Convex-Dev/convex --skill convex-db -a codex`. Or copy the skill folder (.agents/skills/convex-db in Convex-Dev/convex) into .agents/skills/convex-db in your project. Codex loads it when a task matches its description.
Can I use Convex DB 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-db -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-db, .gemini/skills/convex-db, .github/skills/convex-db and .opencode/skills/convex-db in your project.
What does Convex DB need to run?
SKILL.md names no scripts, command-line tools or credentials: Convex DB is instructions for the agent only.
Does Convex DB 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 Convex DB safe to install?
