Analyzes a repository or branch and generates a meaningful, engineer-friendly timeline of changes — grouping commits into logical units with short and detailed descriptions, using git history, changelogs, GitHub PRs, and Linear tickets. Use when you want to understand what changed, when, and why in a codebase.
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
# Repo Timeline Visualize the history of a repository or branch as a meaningful, grouped timeline — not raw git log, but an engineer-friendly narrative of what changed, when, and why. ## Preferences _On startup, use the Read tool to load `~/.claude/skills/repo-timeline/preferences.md`. If it doesn't exist, use defaults._ ## Context _On startup, use Bash to detect: current git branch, repo root (`git rev-parse --show-toplevel`), repo name (`basename $(git rev-parse --show-toplevel)`), remote URL (`git remote get-url origin`), and GitHub repo name (`gh repo view --json nameWithOwner -q .nameWithOwner`). Skip any that fail._ ## Command routing Check `$ARGUMENTS`: - **`help`** → display help then stop - **`config`** → interactive setup then stop - **`reset`** → delete `~/.claude/skills/repo-timeline/preferences.md`, confirm, stop - **branch name** — if argument looks like a branch name (no `--` prefix), use it as the target branch - **flags** — parse `--since`, `--until`, `--focus`, `--depth`, `--sources` - **empty** — use current branch with defaults ### Flags Parse from `$ARGUMENTS`: …

How to install
mdr add mostafa-drz/claude-skills/repo-timeline@sha256:645d4de197c347f9The line at the top of this page pins the label git:20260911.22df896, 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.
