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

period-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 5d 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.

- Never moralize. Never manufacture urgency.

How it starts

The opening of the file, as written. The whole thing — 95 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Mid-period check-in. The period is live — things have happened, things have changed. This is a space to adjust the plan, reflect on direction, or surface something that's been building. Could be a quick tweak or a real conversation. Read the room.

Context

Target period with children so far (created if missing): !G=$0; O=$1; binder read $(bun scripts/journal.ts ${G:-w} ${O:-0} --key) -f "key,goal,plan,achievements,events,learnings,children(key,goal,plan,achievements,events,learnings,summary,totalScore)" --format yaml

Parent context: !G=$0; O=$1; binder read $(bun scripts/journal.ts ${G:-w} ${O:-0} --key) -f "parent(key,goal,plan,achievements,events,learnings)" --format yaml

Previous period: !G=$0; O=$1; binder read $(bun scripts/journal.ts ${G:-w} $(( ${O:-0} - 1 )) --key) -f "goal,plan,achievements,events,learnings,summary,totalScore" --format yaml

Open with a brief pulse (one message, short)

Read the period's plan, goal, current learnings, and children completed so far. Deliver a compact snapshot:

  • Progress: which plan items have seen real movement (from children's achievements/summaries)
  • Stalled: which plan items have had no activity
  • Learning signal: one pattern that is becoming clear from current activity
  • Parent thread: one line connecting this to the parent period's goal — are we on track at the larger scale?

If something stands out — a pattern, drift from the goal, unexpected momentum — name it in one honest line.

Then open the floor:

"What's changed? Anything to add, drop, or rethink?"

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

Then listen

I might bring:

  • New items that came up and need to go on the plan
  • Items I forgot when planning that should have been there
  • Items that are effectively done and should be noted
  • Unexpected events worth capturing now
  • A shift in priorities — something matters more or less than before
  • A broader reflection on whether the goal still makes sense
  • A fresh learning from recent activity that should be captured now
  • Frustration about pace, focus, or direction
  • Something unrelated to the plan

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.
