Pattern Extraction

Extract patterns from Claude Code sessions:

mur learn extract --auto

Murmur reads session transcripts from ~/.claude/projects/ and identifies:

Corrections you made
Coding standards you enforced
Explanations you provided

Direct Usage

You can still use Claude directly:

claude "explain this code"

Or through murmur:

mur search "explain this code"

Cost Considerations

Claude Code uses Anthropic API credits. Murmur helps save costs by:

Routing simple questions to free tools (Gemini)
Tracking usage in mur stats
Showing estimated spend

Troubleshooting

Claude Not Found

which claude
# If empty, add npm global bin to PATH:
export PATH="$PATH:$(npm root -g)/../bin"

Authentication Issues

Claude Code requires API key or OAuth:

claude login

Sessions Not Found

Pattern extraction needs access to ~/.claude/projects/. Ensure this directory exists and has session data.
