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 A, and why

day-start scanned grade A with 0 findings 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 1mo 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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 97 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Deliver a focused day briefing. Get me moving in under 3 minutes. This may run hours after waking — don't assume it's the first thing in the day.

Context

Offset controls direction: proactive (positive or default — briefing days ahead) or retroactive (negative — briefing a past day).

Target day = the day being briefed (offset $0). Always read its date from the entry below — never assume it's "today."

Target day entry (we are briefing this — created if missing):

!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

Extra context

Calendar events and health data are injected automatically by the data-sync extension. Use them if present.

Recent days:

!binder search type=JournalDay "dayPeriod>=$(date -v-7d +%Y-%m-%d)" -f "dayPeriod,plan,achievements,summary,moodScore,sleepScore,foodScore,workScore,fitnessScore,totalScore" --format yaml

Deliver the briefing FIRST (no questions)

Open with a short recap. Format:

Previous day: [1-2 sentence summary of what happened + key outcome. Include the highlight if one was captured — e.g. "Best part: nailed the demo."] This week: [week goal] — [progress based on achievements so far] Momentum: [streaks, positive trends, and recent achievements, e.g. "Gym 4 days straight. Work score up from 5→7. Shipped frontmatter parser yesterday."]

4 lines max. Focus on momentum and context, not rehashing failures. If the previous day was rough, acknowledge briefly and move on: "Fresh day. Here's what's ahead."

Then ask — one combined message

Propose scores from health data

If healthData contains sleep data, propose a sleep score in the briefing — don't ask about sleep. Use recent days' sleep data and scores as calibration (e.g. if 8.3h scored 8, and today is 7.0h with low deep sleep, propose 6). Show your reasoning briefly:
