Skills for the NDIF Ecosystem

Agent skills for neural network interpretability with NNsight.

Compatible with both Claude Code and OpenAI Codex via the Agent Skills Specification.

Installation

Claude Code

# Open Claude Code terminal
claude

# Add the marketplace (one time)
/plugin marketplace add https://github.com/ndif-team/skills.git

OpenAI Codex

# Open OpenAI Codex terminal
codex

# Install skills
skill-installer install https://github.com/ndif-team/skills.git

Included Skills

Skill	Use When...
nnsight-basics	Setting up models, tracing activations, saving values, basic interventions
logit-lens	Analyzing layer-wise predictions, understanding information flow
activation-patching	Finding causally important layers, heads, or positions
attribution-patching	Scaling circuit analysis with gradient approximations
causal-tracing	Investigating information flow and mediation
model-steering	Controlling outputs with steering vectors and persistent edits

Example Prompts

Once installed, just ask naturally:

• "Help me implement logit lens to see what GPT-2 predicts at each layer"
• "Find which attention heads are important for this task using activation patching"
• "Create a steering vector to make the model more positive"
• "Trace where the model stores factual information about the Eiffel Tower"

The agent will automatically apply the relevant skills.
