agentation

agentation is a skill for Claude Code, Codex from heyAyushh/stacc. It costs 14 tokens per session (367 once invoked), scanned A, a copy of agentation, MIT.

A setup guide for adding Agentation, a visual feedback toolbar, to a Next.js project. The toolbar lets developers annotate a page while running the development server.

In plain words
What is it for?
Use it to install and configure Agentation in a Next.js App Router or Pages Router project, then verify that its floating toolbar appears during development.
Why use it?
It gives developers a way to point out interface issues directly on the page instead of describing their location separately. The guide also keeps the toolbar limited to development use.

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

agentation 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 yesterday.

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.

What it actually says

Agentation Setup

Set up the Agentation annotation toolbar in this project.

Steps

  1. Check if already installed

    • Look for agentation in package.json dependencies
    • If not found, run npm install agentation (or pnpm/yarn based on lockfile)
  2. Check if already configured

    • Search for <Agentation or import { Agentation } in src/ or app/
    • If found, report that Agentation is already set up and exit
  3. Detect framework

    • Next.js App Router: has app/layout.tsx or app/layout.js
    • Next.js Pages Router: has pages/_app.tsx or pages/_app.js
  4. Add the component

    For Next.js App Router, add to the root layout:

    import { Agentation } from "agentation";
    
    // Add inside the body, after children:
    {process.env.NODE_ENV === "development" && <Agentation />}
    

    For Next.js Pages Router, add to _app:

    import { Agentation } from "agentation";
    
    // Add after Component:
    {process.env.NODE_ENV === "development" && <Agentation />}
    
  5. Confirm setup

    • Tell the user to run their dev server and look for the Agentation toolbar (floating button in bottom-right corner)

Notes

  • The NODE_ENV check ensures Agentation only loads in development
  • Agentation requires React 18
  • No additional configuration needed — it works out of the box
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.
