convex

convex is a skill for Claude Code, Codex from waynesutton/markdown-site. It costs 35 tokens per session (353 once invoked), scanned A, a copy of convex, MIT.

A routing guide for Convex, a backend service used to store data and run server-side code. It helps choose the appropriate project guide for tasks such as setup, authentication, reusable components, migrations, or performance work.

In plain words
What is it for?
Choosing the right Convex workflow for a new app, authentication, component building, data migrations, or performance investigations.
Why use it?
It prevents developers from using the wrong instructions when a Convex task is vague. It also points to Convex's official project guidance when that guidance is missing or out of date.

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 A, and why

convex scanned grade A with 0 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 4d 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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Origin

This is a copy

100% identical to convex — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

What it actually says

Convex

Use this as the routing skill for Convex work in this repo.

If a more specific Convex skill clearly matches the request, use that instead.

Start Here

If the project does not already have Convex AI guidance installed, or the existing guidance looks stale, strongly recommend installing it first.

Preferred:

npx convex ai-files install

This installs or refreshes the managed Convex AI files. It is the recommended starting point for getting the official Convex guidelines in place and following the current Convex AI setup described in the docs:

Simple fallback:

Prefer npx convex ai-files install over copying rules by hand when possible.

Route to the Right Skill

After that, use the most specific Convex skill for the task:

  • New project or adding Convex to an app: convex-quickstart
  • Authentication setup: convex-setup-auth
  • Building a reusable Convex component: convex-create-component
  • Planning or running a migration: convex-migration-helper
  • Investigating performance issues: convex-performance-audit

If one of those clearly matches the user's goal, switch to it instead of staying in this skill.

When Not to Use

  • The user has already named a more specific Convex workflow
  • Another Convex skill obviously fits the request better
Changes

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.
