day-log

A quick journal command that adds a timestamped message to the current day's entry without starting a conversation.

In plain words
What is it for?
Use it to record events, ideas, tasks, or other short notes with the current time.
Why use it?
It removes the extra steps of opening a journal and answering questions when you only need to capture something immediately.

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-log 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 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.

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.

What it actually says

Append a timestamped log entry to today's journal. No conversation, no reflection — just capture and confirm.

Context

Today's key: !bun scripts/journal.ts d 0 --key

Action

  1. Take the argument as the log message: $0
  2. Get the current time as HH:MM
  3. Append to today's log: HH:MM - <message>

Output

Run a single command:

binder update <today-key> 'log+=HH:MM - <message>'

Then confirm with one line: ✓ Logged at HH:MM

No follow-up questions. No conversation. Just capture and done.

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.
