Inject MD drops a Markdown instruction file (like AGENTS.md) into any project you’ve worked in — right where the coding agent will read it. Works fully offline.

Open it

Press A from any app.

How it works

1

Pick the file

Press A, then pick which Markdown file to inject (AGENTS.md by default).
2

Pick a project

A palette of every project you’ve run Claude Code or Codex in appears, distilled from your session traces.
3

Inject

Pick a project. The file is written into that project’s folder, exactly where the agent looks for it.

Privacy

Local. The project list comes from on-disk traces; the file is written locally.
