description

Mine your own Claude Code conversation logs to extract one model's reasoning discipline and port it to the model you run now. Use when someone wants to capture how a model like Fable 5 or Opus thinks, measure its working habits from real session logs, or turn that into a Mindset.md operating manual another model can adopt. Triggers include "extract the mindset", "study how Fable thinks", "port the discipline", "measure my model's habits", "what made that model good", "build a mindset file from my logs".

Extract Mindset

You cannot clone a model's raw capability. When a model gets suspended or you switch off it, the weights are gone. But the model left a paper trail in your own Claude Code logs, and that trail holds something portable. Not the talent, the DISCIPLINE. How it reasoned before acting. How it re-read results before deciding. How it grounded before it touched anything. That discipline can be measured from the logs and written down as an operating manual the model you run now can adopt.

This skill does that end to end. It builds a corpus of one model's turns from your history, measures its habits against a baseline model so you have evidence and not vibes, then has the current model read that corpus and write a Mindset.md you point sessions at. It works for ANY model id on your disk, not just Fable.

The scripts live in scripts/discipline/ at the MNESTIS repo root. The blank manual to fill in lives in skills/extract-mindset/references/mindset_template.md.

Step 0. Ask one thing first, full walkthrough or fast track

Before anything else, ask the person one question and wait.

"Do you want the full walkthrough where I explain each step as we go, or the fast track where I just build the corpus, measure the habits, and hand you the Mindset.md."

On fast track, run Steps 2 through 5 back to back with short status lines and skip the teaching asides. On full walkthrough, pause after each step, show what came back, and explain it in one or two plain sentences before moving on.

Step 1. Pick the model to study

List every model id on disk:

grep -rho '"model":"[^"]*"' ~/.claude/projects/ 2>/dev/null \
  | sort | uniq -c | sort -rn | head -20

Ask which model to study (TARGET, e.g. claude-fable-5) and which baseline (e.g. claude-opus-4-8).

---

Step 2. Build the corpus

bash scripts/discipline/extract_model_corpus.sh <target-model-id> > /tmp/<target>_corpus.jsonl
wc -l /tmp/<target>_corpus.jsonl

---

Step 3. Measure the habits

python3 scripts/discipline/analyze_discipline.py <target-model-id> <baseline-model-id>

Save the table for the Mindset appendix.

---

Step 4. Write the Mindset.md

Use skills/extract-mindset/references/mindset_template.md as the shape. Distill from the corpus — do not invent. Paste the measured table into the appendix.

---

Step 5. Wire it in

Offer to:

1. Reference the Mindset in CLAUDE.md or point Cursor at .MNESTIS/integrations/fable-mindset.md
2. Set effort level to max on the adopting model
3. Add a PostToolUse hook on Edit|Write|MultiEdit that runs the project test command

MNESTIS users can also run MNESTIS setup --platform cursor to install MNESTIS-discipline.mdc with Fable-grade habits baked in.
