Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Published

Scan local and public repos for AI agent context cost — detect CLAUDE.md, AGENTS.md, .cursorrules and calculate token costs across all major LLM providers

Readme

AgentLens

Scan de repositórios para custos de contexto de agentes de IA. Detecta CLAUDE.md, AGENTS.md, .cursorrules, copilot-instructions.md e calcula custos de tokens para os principais LLMs.

Funciona de três formas — escolha a que se encaixa no seu fluxo.


App (HTML)

Zero instalação. Baixe agentlens.html, abra no browser.

  • Analisa repositórios públicos do GitHub via API
  • Carrega relatórios .json gerados pelo CLI
  • Toggle de idioma PT/EN
  • Aba Compare para comparar múltiplos repos
1. Baixe agentlens.html
2. Abra no Chrome, Firefox, Safari ou Edge
3. Cole: https://github.com/owner/repo → Analisar

All processing happens in your browser via the GitHub public API.


CLI

Analisa repositórios locais e gera relatório HTML + JSON.

# Com npx (sem instalação)
npx @hugofusinato/agentlens
npx @hugofusinato/agentlens /caminho/do/repo
npx @hugofusinato/agentlens --path . --path ../outro-repo

# Ou instale globalmente
npm install -g @hugofusinato/agentlens
agentlens /caminho/do/repo

# Opções úteis
agentlens --stdout          # JSON no stdout
agentlens --no-open         # não abre browser automaticamente
agentlens --out meu-repo    # nome do arquivo de saída

Gera agentlens-report.html e agentlens-report.json no diretório atual.


Servidor com histórico

API REST HTTP que analisa repositórios e persiste os resultados em banco de dados SQLite local.

npm install
node server.js              # porta 3000 (padrão)
PORT=8080 node server.js    # porta customizada

Endpoints

| Método | Rota | Descrição | |--------|------|-----------| | POST | /analyze | { "path": "/caminho/repo" } — analisa e salva | | GET | /history | Lista todas as análises salvas | | GET | /history/:id | Análise completa por ID | | DELETE | /history/:id | Remove uma análise |

O app HTML pode ser apontado para GET /history para exibir o histórico de análises salvas.

O banco de dados fica em agentlens-history.db no diretório de trabalho. Cada análise salva a versão do CLI (cliVersion) para rastrear compatibilidade entre versões.


Testes

npm test

Roda testes unitários do core e testes de integração da API com node:test nativo (Node.js ≥ 18, sem dependências extras).


Config (opcional)

Crie .agentlens.json para definir múltiplos repos de uma vez:

{
  "repos": [
    { "path": ".", "name": "meu-repo" },
    { "path": "../outro-repo" }
  ],
  "output": "relatorio.html"
}

Veja .agentlens.example.json para referência completa.
