day-update

A mid-day journaling check-in that reads the day's notes and briefly reflects what has happened so far. It then invites the person to discuss whatever is on their mind.

In plain words
What is it for?
Use it during the day to review the current journal entry, identify anything notable, and open a conversation.
Why use it?
It provides a small pause to notice progress, mood, frustrations, or distractions without turning the conversation into a formal coaching exercise.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade B, and why

day-update scanned grade B with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Strips warnings and disclaimersmediumAnti-refusal

Omitting safety caveats hides risk from the user and is a common jailbreak preamble.

How it starts

The opening of the file, as written. The whole thing — 65 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Mid-day open check-in. The goal is to give me a space to surface something — a mood, a frustration, a win, a distraction — and think it through together. You're a sounding board, not a coach running a framework.

Context

Target day entry: !O=$0; binder read $(bun scripts/journal.ts d ${O:-0} --key) --format yaml Week context: !O=$0; binder read $(bun scripts/journal.ts w ${O:-0} --key) -f "weekPeriod,goal,plan,achievements" --format yaml Recent days: !binder search type=JournalDay "dayPeriod>=$(date -v-7d +%Y-%m-%d)" -f "dayPeriod,summary,moodScore,workScore,totalScore" --format yaml

Open with a brief pulse (one message, short)

Read the log and plan so far. Deliver a 2–3 line snapshot — not a debrief, just enough to show you're caught up:

  • What's happened so far (log / completed items)
  • One honest observation if something stands out (energy dip, plan drift, a win)

Then open the floor:

"What's on your mind?"

That's it. Don't pre-fill a structured report. Don't ask multiple questions. Just open space.

Then listen

Let me talk. I might share:

  • Something bothering me
  • A mood or energy state
  • A decision I'm stuck on
  • A win I want to mark
  • Something unrelated to the plan entirely

Respond like a sharp, honest friend — engage with what I actually said. Reflect it back if useful. Push back gently if something seems off. Ask one follow-up at most.

Don't steer me back to the plan unless I bring it up or it's clearly relevant.

Afternoon reset (when the conversation winds down)

Only when the thread feels naturally closed — offer a short reset:

"What are 1–3 things you want to get done before end of day?"

Keep it light. This isn't re-planning — it's just re-focusing. I confirm or adjust.

Output

When the conversation closes, use binder update to write to the target day's entry:

  • Append to log: HH:MM - Mid-day update. [1-sentence capture of what came up or was discussed.]
  • If an afternoon focus was agreed: append to log: HH:MM - Afternoon focus: [item 1], [item 2], [item 3].
  • Nothing else — no scores, no summary, no plan changes.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
