Use whenever the directory shape of a Lossless pseudomonorepo (or any child repo) changes — a new top-level directory is added, a submodule is mounted or unmounted, a major subsystem is renamed — or on a weekly cadence, or before any release that would land on GitHub, to regenerate the `FILEMAP.md` at each affected repo's root so collaborators see the current shape without cloning. Triggers when the user mentions "filemap", "tree", "directory layout", "repo overview…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# maintain-filemap · Loop > **When the directory shape changes, regenerate the map.** The committed `FILEMAP.md` at each repo root is the artifact a new collaborator opens first. ## What this loop does Keeps a `FILEMAP.md` at the root of each Lossless repo current with the actual on-disk tree. Each `FILEMAP.md` has two parts: 1. **A curator preface** — hand-authored prose explaining what each top-level directory IS (purpose, ownership, conventions). Edited rarely (only when the meaning of a directory changes, not when its contents do). 2. **A generated tree** — produced by `tree -L 3` with a curated ignore set, spliced between `<!-- TREE-START -->` and `<!-- TREE-END -->` sentinels in a fenced code block. Regenerated by the loop's script every time the discipline fires. Why both: a raw `tree` dump is useful but doesn't tell a newcomer *what they're looking at*. The curator preface is what makes the file legible; the generated tree is what makes it accurate. ## When this loop fires Three triggers: | Trigger | Cadence | How it fires | |---|---|---| | Directory-shape change | as-it-happens | Pre-commit hook, OR manually as part of the commit that changes shape | …

How to install
mdr add lossless-group/lossless-agent-skills/maintain-filemap@sha256:2b7cf6c8a7496786The line at the top of this page pins the label git:20260611.c473e40, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
