Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00032 | $0.00565 |
| Opus 5 | $0.00016 | $0.00282 |
| Sonnet 5 | $0.00006 | $0.00113 |
| Haiku 4.5 | $0.00003 | $0.00056 |
Grade A, and why
extract-document-insights 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 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.
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 — 65 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Extract Document Insights
Extract insights from EXTERNAL documents with proper epistemic classification.
Purpose
User-invocable wrapper that spawns the document-insight-extractor subagent to:
- Extract research findings, theoretical frameworks, hypotheses
- Classify epistemic status (confirmed, theoretical, speculative)
- Store in session-based folders
- Deduplicate against existing knowledge base
- Save to
Brain/Document Insights/[session]/
When to Use
- Analyzing research papers, academic articles
- Processing books or book chapters
- Extracting insights from web articles, reports
- Any EXTERNAL content (not your personal thoughts)
NOT for personal content - use /extract-insights for your conversations, transcripts.
Usage
/extract-document-insights "2025-02-21 Ancient Wisdom Research" /path/to/document.md
/extract-document-insights "AI Agent Papers" "the transcript above"
Session name is REQUIRED - describes the research session for organization.
Process
-
Parse arguments to extract session name and source
-
Spawn document-insight-extractor subagent via Task tool with:
Task( subagent_type="document-insight-extractor", prompt="Extract insights from: [source] into session '[session-name]'. Follow your mandatory workflow - contextualize, classify epistemically, search duplicates, create notes, update changelog." ) -
Report results - number of insights extracted, session folder path
-
Suggest insight interview - Present to user:
"[N] insights from [source] saved to
Brain/Document Insights/[session]/.Before these get indexed, consider running
/insight-interview [topic]to capture your own angles - where you agree, disagree, or see connections the research missed. Your responses save toBrain/AI Extracted Notes/and both sets will be available for the next connection discovery run.Run
/insight-interview [topic]to continue, or skip if you want to index these as-is."
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.

extract-document-insights is a skill published in the GitHub repository Abilityai/cornelius (106 stars, last pushed 12d ago), licensed MIT. It adds 32 tokens to every session and 565 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.

hr-onboarding
A new-hire onboarding plan as a single page — first week schedule, buddy + manager intro, learning track, equipment checklist, and "you're set when…" outcomes. Use when the brief mentions "onboarding", "new hire", "first week plan", or "入职".

Take any book (EPUB/PDF), produce a personalized chapter-by-chapter analysis. Each chapter is preserved in detail (The Chapter) and mirrored back to the reader's actual life (The Mirror) using brain context.

eli5
Explain research, papers, or technical ideas in plain English with minimal jargon, concrete analogies, and clear takeaways. Use when the user says "ELI5 this", asks for a simple explanation of a paper or research result, wants jargon removed, or asks what something technically dense actually means.
