Persist design documents with branch tracking, revision chains, and cross-session discovery.
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
# Design Document Lineage
When a design introduces or changes domain terms, load
`skills/blocks/domain-modeling.md`. Record each definition in the existing design
lineage artifact with its evidence source, checked time, and scope. A changed
definition invalidates dependent decisions. Link and reopen them instead of
leaving stale implementation guidance marked current.
## Overview
Persist design documents from brainstorming and planning sessions with branch tracking, revision chains, and cross-session discoverability. Design docs are immutable after creation -- new revisions supersede prior versions rather than editing in place.
---
## Storage Location
All design documents are stored under:
```
~/.claude-octopus/designs/<project-slug>/
```
The project slug is derived from the current git repository name or working directory basename:
```bash
SLUG=$(basename "$(git rev-parse --show-toplevel 2>/dev/null || pwd)")
DESIGNS_DIR="${HOME}/.claude-octopus/designs/${SLUG}"
mkdir -p "$DESIGNS_DIR"
```
---
## Filename Format
Design documents follow a strict naming convention:
```
{user}-{branch}-design-{datetime}.md
```

How to install
mdr add nyldn/claude-octopus/skill-design-lineage@sha256:7bea6e6e1fd5809bThe line at the top of this page pins the label git:20260906.89d2d35, 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.
