| 🧠 Core Question | Names the real underlying question — not what you asked, but what you're actually facing |
| 🔍 Blind Spot | Surfaces what you likely can't see from where you're standing |
| 🚀 Growth | Points toward what needs to change, with a concrete first step |

🧠 ASKCHARLIE — Layer 1: Core Question
━━━━━━━━━━━━━━━━━━━━━━
What the situation is really asking:
The question isn't whether to keep going — it's whether you're
attached to the work or attached to the outcome.
How Sunk Cost Fallacy approaches this question:
Instead of asking "how do I make these 8 months worth it,"
ask "if I started this today, would I still commit 15 hours a week?"
Insight revealed by this model:
The time invested feels like a reason to continue. It isn't.
Three months of stalled growth is the actual signal.
Where this model breaks:
Sunk cost identifies what to ignore — it can't tell you how much
future investment the opportunity actually deserves.
Invoke /askcharlie followed by a problem, situation, or condition.
Problem — something you're actively struggling with:
/askcharlie
I keep starting new books, courses, and projects but rarely finish them.
I've abandoned 4 different learning paths in the last year alone.
I genuinely want to change this pattern. What do you suggest?
Situation — a decision or crossroads you're facing:
/askcharlie
I've been working on a side project for 8 months. It has 12 paying users
but growth has stalled for 3 months. I'm spending 15 hours/week on it.
Should I double down or let it go?
Condition — a recurring pattern or state you want to understand:
/askcharlie
My team keeps shipping features but the product isn't growing.
We've released 11 updates in 6 months. Users sign up but churn within 2 weeks.
I don't know if this is a product problem or a market problem.
Then rate the analysis: ac1 through ac5 (or just 1–5).
charlie-munger-index.md is the knowledge base the LLM draws from at every analysis. The Selector Agent reads the full table before choosing models — it doesn't rely on the model's built-in knowledge of Munger's work. What's in the index is what gets used.
86 models, each mapped to:
- What question it helps solve
- What blind spot it reveals
- What development area it strengthens
You can extend, edit, or replace entries — the Selector Agent picks from whatever is in the file.

INDEXING - Charlie Munger Index.md |
86 mental models — the knowledge base |
- Claude Code with a skill plugin (e.g. Superpowers)
- An Obsidian vault or any folder Claude can read/write
- Place
askcharlie.mdin your Claude Code skills folder - Place
INDEXING - Charlie Munger Index.mdsomewhere Claude can read - Replace placeholders in
askcharlie.md:
| Placeholder | Replace with |
|---|---|
YOUR_VAULT_PATH |
Absolute path to your vault or notes folder |
YOUR_PERSONAL_PROFILE.md |
A short markdown note about yourself — optional but makes model selection feel personal |
YOUR_LOG_PATH |
Where you want the log file saved |
YOUR_FALLBACK_PATH |
Backup write path if primary is unavailable |
- Create a folder called
NO CONTEXT ASK CHARLIE/in your vault. Analysis notes are saved here automatically.
Before selecting models, the skill can read a short profile file about you — your tendencies, recurring challenges, decision-making patterns. This makes the selection feel personal rather than generic.
