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

nightshift-hook 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.

Research Hook: Nightshift Integration

Command Context

When to Reference Research Module

Always reference when:

  • Nightshift overnight pipeline is executing
  • Research queue has pending TODO items in research_learning.org
  • Need to process links and generate podcasts before morning briefing

Key decisions this hook informs:

  • How many items to process this cycle (respects max_sources_per_night)
  • Whether to generate podcasts (checks nlm availability)
  • Which focus areas have the most pending items

Quick Reference

Question Answer
When does this run? Nightshift research timer (02:00 UTC)
What does it process? TODO items from research_learning.org
Does it generate podcasts? Yes, if nlm CLI is available and >= 3 sources processed
What's the processing limit? max_sources_per_night setting (default 20)
What outputs are created? Literature notes, zettels, podcasts, journal entry, action items

Agents This Hook Invokes

Agent Purpose
research-orchestrator Full pipeline: discovery, extraction, synthesis, podcasts, post-processing

Integration Points

  • research_learning.org - Source of TODO items to process
  • research-orchestrator agent - Invoked in nightshift mode (non-interactive)
  • podcast-creator agent - Spawned by orchestrator for podcast generation
  • 0-personal/content/podcasts/ - Podcast output directory
  • Journal - Session summary written to daily journal

This hook is invoked by nightshift for overnight research processing.

Trigger

Called by nightshift scheduler via nightshift run --command=/research-daily.

Mode

Non-interactive. No user confirmation needed — process all eligible TODO items.

Workflow

Step 1: Count and Prioritize Research Queue

Read research_learning.org and count pending items:

import sys
from pathlib import Path

sys.path.insert(0, '.datacore/modules/research/lib')

data_root = Path.home() / "Data"
research_org = data_root / "0-personal" / "org" / "research_learning.org"

# Count TODO items
todo_count = 0
if research_org.exists():
    content = research_org.read_text()
    todo_count = content.count("** TODO") + content.count("*** TODO")

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.
