A passive daily work journal that Claude keeps FOR you so you never have to write it yourself. Append short entries after meaningful work (what was done, what you focused on, artifacts touched) to 01-daily/journal/YYYY-MM-DD.md. Run a guided reflection at night or in the morning. Use when you run /daily-journal, say "log this to my journal", "add to today's journal", "reflect on today/yesterday", or when finishing a meaningful chunk of work in any session.

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

# Daily Journal

## Purpose
Keep an **automatic, passive** journal of your workdays so you don't have to write one. Claude logs what got done as it happens; you optionally run a reflection later. This is distinct from `/weekly-checkin` (which is a manual reflection where you supply the input) — here **Claude is the author** and the log accrues in the background.

Two modes:
1. **`log`** (default, mostly invoked implicitly) — append a short entry to today's journal.
2. **`reflect`** — read the day's log (+ recent days) and run a guided reflection with you.

## Storage
- One file per day: `01-daily/journal/YYYY-MM-DD.md` (use `date +%F` for today's date; never guess).
- Create the file from the template below on the first entry of the day.
- Append only — never rewrite earlier entries. Newest entries go at the bottom of the Log section.

## When to log (procedure for the always-apply trigger)
The trigger itself lives in `CLAUDE.md` § Daily Journal (ALWAYS APPLY), because a skill body is lazily loaded and cannot fire itself. This section is the procedure that trigger runs.

How to install

The exact contents, by fingerprint

mdr add huytieu/cog-second-brain/daily-journal@sha256:65de46c992aacfea

The line at the top of this page pins the label git:20260818.dc5aeb6, 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.
