Journal

Reconstruct today's work from git history (not session context) and write it to the journal. Run it at the end of the day; re-running regenerates today's entry idempotently.

Config

Read from ~/.claude/CLAUDE.md:

• journal-backend — obsidian (default) | inkdrop.
• journal-path — where journal files live (for obsidian).
• journal-roots — comma-separated directories to scan for git repos (where you keep your projects). Defaults to ~ if unset.
• journal-emails — comma-separated list of ALL your git author emails (every identity you commit with). Used to attribute commits across repos that may be configured with different user.email.
• journal-work-hosts — optional comma-separated remote-host substrings that mark a repo as work (e.g. your company's git host). Repos whose origin matches go under a Work section; everything else under Personal. If unset, no split — all repos go under one list.

If journal-backend is missing, ask the user once and offer to write the keys. If it names an unsupported backend, stop: journal-backend not supported; supported: obsidian, inkdrop. If journal-emails is missing, fall back to each repo's git config user.email and warn that cross-identity commits may be missed.

Reconstruct the day

1. Find repos: for each directory in journal-roots, run find -maxdepth 4 -type d -name .git and take each parent as the repo root. Depth 4 catches both top-level repos (.git at depth 2) and repos nested two levels under a root. Exclude the vault repo itself (the git root containing journal-path) to avoid logging the journal's own commits.
2. For each repo, collect today's commits across all branches (not just HEAD) authored by any of your emails:

``bash git -C "$repo" log --all --since="00:00" --no-merges \ --pretty=format:'%h%x09%ae%x09%s' ` Keep only lines whose author email (2nd field) is in journal-emails; drop the rest (others' commits). --all is essential: work is often done on per-ticket feature branches, so the checked-out branch (often master/main`) may not contain today's commits. Skip repos with no matching commits.

1. If journal-work-hosts is set, classify each repo by its origin remote host:

``bash git -C "$repo" remote get-url origin ``

• host matches an entry in journal-work-hosts → Work
• otherwise → Personal

If journal-work-hosts is unset, skip the split and list all repos under one section.

1. For each repo with commits, synthesize a 1-line summary from that day's commit subjects (derivable from the commits — no session context needed).

Build the entry

# YYYY-MM-DD

## Work
### 
> 
-  (``)

## Personal
### 
> 
-  (``)

• Omit a section entirely if it has no commits. With no journal-work-hosts, drop the section headers and list repos directly under the date.
• No Prompt or Difficulties fields — they are not derivable from git.
• If the user passed an argument, append it under a ## Notes section.

Write

obsidian (default)

1. Write the entry to /.md, overwriting any existing file for today (the reconstruction is the full day, so regeneration is idempotent).
2. Commit it in the vault so the entries are versioned:

``bash git -C "" add "/.md" git -C "" commit -m "journal: " >/dev/null 2>&1 || true ` ( is the git root containing journal-path`.)

inkdrop

Find or create today's note (YYYY-MM-DD) in the Journal notebook (list-notebooks). Write the reconstructed entry. Status none.
