# Analysis modules to run (subset of the 27 available)
analysis:
- alignment_imprint # Detect DPO/RLHF/CAI/SFT training method
- concept_geometry # Map refusal cone geometry

"""Add a new slide to an unpacked PPTX directory.
Usage: python add_slide.py <unpacked_dir> <source>
The source can be:
- A slide file (e.g., slide2.xml) - duplicates the slide
- A layout file (e.g., slideLayout2.xml) - creates from layout
Examples:
python add_slide.py unpacked/ slide2.xml
# Duplicates slide2, creates slide5.xml
python add_slide.py unpacked/ slideLayout2.xml
# Creates slide5.xml from slideLayout2.xml
To see available layouts: ls unpacked/ppt/slideLayouts/

# Jupyter Live Kernel (hamelnb)
Gives you a **stateful Python REPL** via a live Jupyter kernel. Variables persist
across executions. Use this instead of `execute_code` when you need to build up
state incrementally, explore APIs, inspect DataFrames, or iterate on complex code.
## When to Use This vs Other Tools
| Tool | Use When |
|------|----------|
| **This skill** | Iterative exploration, state across steps, data science, ML, "let me try this and check" |
| `execute_code` | One-shot scripts needing hermes tool access (web_search, file ops). Stateless. |
| `terminal` | Shell commands, builds, installs, git, process management |
**Rule of thumb:** If you'd want a Jupyter notebook for the task, use this skill.
## Prerequisites
1. **uv** must be installed (check: `which uv`)
2. **JupyterLab** must be installed: `uv tool install jupyterlab`
3. A Jupyter server must be running (see Setup below)
## Setup
The hamelnb script location:
```
SCRIPT="$HOME/.agent-skills/hamelnb/skills/jupyter-live-kernel/scripts/jupyter_live_kernel.py"
```
If not cloned yet:
```
git clone https://github.com/hamelsmu/hamelnb.git ~/.agent-skills/hamelnb
```
### Starting JupyterLab
Check if a server is already running:
```
uv run "$SCRIPT" servers
```
If no servers found, start one:
```
jupyter-lab --no-browser --port=8888 --notebook-dir=$HOME/notebooks \
--IdentityProvider.token='' --ServerApp.password='' > /tmp/jupyter.log 2>&1 &
sleep 3
```
Note: Token/password disabled for local agent access. The server runs headless.
### Creating a Notebook for REPL Use
If you just need a REPL (no existing notebook), create a minimal notebook file:
```
mkdir -p ~/notebooks
```
Write a minimal .ipynb JSON file with one empty code cell, then start a kernel
session via the Jupyter REST API:
```
curl -s -X POST http://127.0.0.1:8888/api/sessions \
-H "Content-Type: application/json" \
-d '{"path":"scratch.ipynb","type":"notebook","name":"scratch.ipynb","kernel":{"name":"python3"}}'
```
## Core Workflow
All commands return structured JSON. Always use `--compact` to save tokens.
### 1. Discover servers and notebooks
```
uv run "$SCRIPT" servers --compact
uv run "$SCRIPT" notebooks --compact
```
### 2. Execute code (primary operation)
```
uv run "$SCRIPT" execute --path <notebook.ipynb> --code '<python code>' --compact
```
State persists across execute calls. Variables, imports, objects all survive.
Multi-line code works with $'...' quoting:
```
uv run "$SCRIPT" execute --path scratch.ipynb --code $'import os\nfiles = os.listdir(".")\nprint(f"Found {len(files)} files")' --compact
```
### 3. Inspect live variables
```
uv run "$SCRIPT" variables --path <notebook.ipynb> list --compact
uv run "$SCRIPT" variables --path <notebook.ipynb> preview --name <varname> --compact
```
### 4. Edit notebook cells
```
# View current cells
uv run "$SCRIPT" contents --path <notebook.ipynb> --compact
# Insert a new cell
uv run "$SCRIPT" edit --path <notebook.ipynb> insert \
--at-index <N> --cell-type code --source '<code>' --compact
# Replace cell source (use cell-id from contents output)
uv run "$SCRIPT" edit --path <notebook.ipynb> replace-source \
--cell-id <id> --source '<new code>' --compact
# Delete a cell
uv run "$SCRIPT" edit --path <notebook.ipynb> delete --cell-id <id> --compact
```
### 5. Verification (restart + run all)
Only use when the user asks for a clean verification or you need to confirm
the notebook runs top-to-bottom:
```
uv run "$SCRIPT" restart-run-all --path <notebook.ipynb> --save-outputs --compact
```
## Practical Tips from Experience
1. **First execution after server start may timeout** — the kernel needs a moment
to initialize. If you get a timeout, just retry.
2. **The kernel Python is JupyterLab's Python** — packages must be installed in
that environment. If you need additional packages, install them into the
JupyterLab tool environment first.
3. **--compact flag saves significant tokens** — always use it. JSON output can
be very verbose without it.
4. **For pure REPL use**, create a scratch.ipynb and don't bother with cell editing.
Just use `execute` repeatedly.
5. **Argument order matters** — subcommand flags like `--path` go BEFORE the
sub-subcommand. E.g.: `variables --path nb.ipynb list` not `variables list --path nb.ipynb`.
6. **If a session doesn't exist yet**, you need to start one via the REST API
(see Setup section). The tool can't execute without a live kernel session.
7. **Errors are returned as JSON** with traceback — read the `ename` and `evalue`
fields to understand what went wrong.
8. **Occasional websocket timeouts** — some operations may timeout on first try,
especially after a kernel restart. Retry once before escalating.
## Timeout Defaults
The script has a 30-second default timeout per execution. For long-running
operations, pass `--timeout 120`. Use generous timeouts (60+) for initial
setup or heavy computation.
