Measure a context plugin on your own repository before you install it

说明与用途

该工具通过在浏览器中下载仓库并使用 Pyodide 运行 chamnan 模块，帮助开发者估算插件注入的上下文大小。

问题

Developers cannot evaluate how much context a plugin will inject into an agent before installing it, risking unnecessary context cost and privacy leaks.

结果

The tool shows that injected context remains bounded (~6.2–6.7 KB) regardless of repo size, providing a reliable estimate of context cost before plugin installation.

工作流

• 1. Open the measurement page at https://arcticfox2029.github.io/chamnan-measure/
• 2. Enter a public GitHub repository URL
• 3. The page downloads the repo into the browser and runs chamnan’s mapper, rollup, and redactor modules via Pyodide
• 4. It calculates the size of the context block that would be injected per session
• 5. It shows which parts would be redacted and simulates 50 turns of interaction with that repo’s files

证据

Paste a public GitHub repository URL. The page downloads the source into your browser tab, runs chamnan's actual modules over it through Pyodide — mapper, rollup, the redactor, not a re‑implementation of any of them — and reports what would be injected into an agent's context each session, what the redactor would alter, and a fifty‑turn simulation over that repository's own files.
