local-convex is a skill for Claude Code from joelhooks/joelclaw. It costs 85 tokens per session (3,944 once invoked), scanned B, original, no licence file.

A guide to running Convex, a backend database platform, on local infrastructure with PostgreSQL and S3-compatible file storage.

In plain words
What is it for?
It is for running Convex locally, connecting it to PostgreSQL and Garage storage, and managing files, buckets, and related services.
Why use it?
It helps configure and troubleshoot a self-hosted backend without relying entirely on a hosted Convex environment.

Getting it into your agent

There is no command for this one: it runs only inside a plugin, and the catalogue could not identify which plugin ships it. The source is linked below.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade B, and why

local-convex scanned grade B with 2 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 5d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Asks for rootmediumPrivilege escalation

A mod that escalates privileges can change anything on the machine, not only the project.

sudo -u joelclaw psql -h /Users/Shared/joelclaw/run -p 5432 -d postgres

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
