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-summary 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 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.

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 — 145 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Read the day's journal entry and close it out in two rounds: first discuss, then score and write.

Context

Offset controls direction: default (0) = today, negative = past day (e.g. -1 for yesterday).

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

Target day entry (we are summarizing 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 ${O:-0} --key) -f "weekPeriod,goal,plan,achievements" --format yaml Extra context: Calendar events, activity dump, and health data are injected automatically by the data-sync extension. Use them if present. Activity dump is background context — not every commit or session is an achievement. Recent days: !binder search type=JournalDay "dayPeriod>=$(date -v-7d +%Y-%m-%d)" -f "dayPeriod,plan,achievements,summary,moodScore,sleepScore,foodScore,workScore,fitnessScore,totalScore" --format yaml


First message — Reflect on the day

After reading the entry, deliver one message. Use plain text throughout — no blockquotes.

1. Day summary

Brief bullet points of what happened based on the log and plan. Cover what got done, what didn't, and anything notable.

Note: log entries may be added retroactively — don't infer energy flow or timing patterns from timestamps alone. Ask if the timeline is unclear.

2. Reflection

Offer a short inferred read on the day — energy, momentum, patterns vs recent days. Honest, not preachy.

3. What's missing?

Numbered list. Call out gaps: things the log doesn't cover, plan items with no mention, anything that feels incomplete. Gaps may mean "not logged yet" rather than "didn't happen" — ask "anything not captured yet?" rather than assuming omission.

4. How was it?

Ask how the day felt overall. One or two targeted questions if something specific stands out from the log. Not open-ended therapy — you already know most of the day.

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.
