The Missing Link: How LUNE Solved My Consistency Problem
After building Emma and Clara for note-taking, I realized the bottleneck wasn't my tools—it was my consistency. LUNE uses daily rituals and structured prompts to finally solve the human problem in my productivity system.
If you're familiar with my previous posts, you'll know I've created two tools to help with my note-taking. There's Emma, a CLI metadata enricher, and Clara, an MCP server that parses my notes and provides context to LLMs. These are good tools, but they're obsolete if there's no data to work with.
Cue Taylor Swift's Anti-Hero: "It's me, hi, I'm the problem, it's me". I haven't been consistent with my note-taking, and the guilt has been eating at me.
To set context: even though I try to take notes throughout the day, I don't. I end up trying to journal, review, and reflect at the end of the day, but often I don't have the energy or drive to do so. To combat this, I created Lune—Logging Utility for Notes and Events.
Meet Lune
Lune is a terminal-based tool that prompts me with questions throughout the day to capture my thoughts, tasks, mood, and experiences while also reminding me of upcoming events and tasks.
I usually invoke Lune after meals because that's when I relax and rejuvenate. After eating, my mind is fresh. Naturally, I added food tracking as part of my rituals. Let me walk you through one of them.

Added to mood DatabaseMorning Ritual example
As you can see, I keep track of how I'm feeling, my breakfast, what I want to focus on for the day, my pending tasks, upcoming events, and a joke to lighten up my day. The joke gets replaced with a hydration reminder in the afternoon and a journaling prompt at night.
After each ritual, the CLI writes everything to my Obsidian daily note. In the backend, I use a SQLite database to keep things organised.
Under the Hood
I built Lune using Typer for the CLI interface and SQLite for data storage. The database tracks my tasks and upcoming events, but more importantly, it creates structured data that I can query with LLMs for insights.
I can analyse mood patterns, correlate what I eat with how I feel, get personalised productivity recommendations, and explore other behavioural connections in my data.
Conclusion
Lune, I hope, is the final piece to the puzzle. So far, it's been helping me stay focused and consistent. My productivity has improved, and I'm more conscious about what I eat.
There are always improvements to make and features to add—automated scheduling through cron jobs instead of manual invocation, or perhaps an agentic AI that learns my patterns and takes over entirely. The possibilities are endless. But for now, I'm happy with how it turned out.
