Step 1: Generate context for your project
npx sigmapStep 2: Ask for relevant files (query-specific context)
sigmap ask "explain the auth flow"
# Outputs: ranked file list + .context/query-context.md (ready to paste)Step 3: Copy context to your AI assistant
.context/query-context.mdStep 4: Save the AI response
# Copy the AI's answer into a file
echo "Paste AI response here..." > response.txtStep 5: Validate coverage (optional)
sigmap validate --query "auth login token"
# Check if coverage is high enough to trust the responseStep 6: Judge groundedness
sigmap judge --response response.txt --context .context/query-context.md
# Score: shows if the answer is grounded in your codeThat flow gives you: a compact signature map · a focused query context · a coverage sanity check · a groundedness score for the answer.
SigMap is no longer just "shrink the context file." Every step has a purpose:
