/radar — Ambient Intelligence Digest

Surfaces recent feed entries, synthesizes them into a grouped digest, and optionally suggests new sources based on your interest profile.

Usage

/radar                         # Default: last 7 days, up to 20 entries
/radar --days 3                # Last 3 days
/radar --limit 10              # Limit to 10 entries
/radar --suggest               # Include source suggestions
/radar --no-store              # Don't save the digest

Trigger phrases: "what's new", "show my digest", "ambient digest", "what have I missed", "feed digest"

Options

Option Description Default
--days <n> Look back period in days 7
--limit <n> Maximum entries to include 20
--suggest Include new source suggestions Off
--no-store Don't store the digest as an entry Stores by default

Output

# Radar Digest — 2026-03-31

12 feed entries from the last 7 days.

## DuckDB
DuckDB 1.2 shipped with improved HNSW index performance and a new
JSON extension for nested document queries.

- v1.2 release includes 3x faster vector search indexing
- New JSON extension supports path-based queries
- Community contribution guide updated

## Claude Code
Two new features landed: hook-based automation and MCP server improvements.

- Session hooks enable custom automation on start/end events
- MCP server now supports parallel tool execution

## Overall Summary
This week saw performance improvements in DuckDB's vector search (directly
relevant to Distillery's storage layer) and new automation capabilities
in Claude Code.

Digest stored: m3n4o5p6

How It Works

  1. Retrieves recent feed entries from the knowledge base (type feed)
  2. Groups entries by source tag or topic
  3. Synthesizes 2-4 sentence summaries per group with bullet points
  4. Generates a cross-group overall summary
  5. If --suggest is enabled, calls distillery_suggest_sources for recommendations
  6. Stores the digest as an entry (type digest) unless --no-store is specified

Tips

  • The digest is stored by default with tags digest/radar/ambient for future retrieval
  • Source suggestions are based on your interest profile (mined from existing entries)
  • Use /watch add to subscribe to suggested sources
  • Groups are organized by source when available, falling back to topic clustering
