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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00043 | $0.03622 |
| Opus 5 | $0.00022 | $0.01811 |
| Sonnet 5 | $0.00009 | $0.00724 |
| Haiku 4.5 | $0.00004 | $0.00362 |
Grade A, and why
convex-quickstart 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 9d 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.

Convex Quickstart
Set up a working Convex project as fast as possible.
When to Use
- Starting a brand new project with Convex
- Adding Convex to an existing React, Next.js, Vue, Svelte, or other app
- Scaffolding a Convex app for prototyping
When Not to Use
- The project already has Convex installed and
convex/exists - just start building - You only need to add auth to an existing Convex app - use the
convex-setup-authskill
Workflow
- Determine the starting point: new project or existing app
- If new project, pick a template and scaffold with
npm create convex@latest - If existing app, install
convexand wire up the provider - Run
npx convex dev --onceto provision a local anonymous deployment, push the currentconvex/code, typecheck it, and regenerate types — all in one shot, exiting cleanly. The output tells the agent whether the schema and functions are valid. - Ask the user (or, for cloud agents, start in the background)
npm run dev— Convex templates wire the watcher and the frontend into a single command. If the project has no combined dev script, usenpx convex devfor the watcher and run the frontend separately. - Verify the setup works
Path 1: New Project (Recommended)
Use the official scaffolding tool. It creates a complete project with the frontend framework, Convex backend, and all config wired together.
Pick a template

React + Vite + Tailwind + shadcn/ui |

What ships with it
2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

convex-quickstart is a skill published in the GitHub repository fiinytid/nexusai.gg (2 stars, last pushed 1mo ago), licensed MIT. It adds 43 tokens to every session and 3,622 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
