mcp__exa__web_search_exa (type="deep") for all Reddit searches
- Max 3 query attempts per search intent; skip if no results
- Target: keep total tool calls under 30
Config

Flow
- Read
{data_dir}/subreddits.jsonl for existing communities
- Read
{data_dir}/keywords.jsonl for search terms
- Read
SKILL_DIR/references/step-details.md Step 2 section for detailed logic
- Use keywords via
mcp__exa__web_search_exa (type="deep") to discover new communities:
"site:reddit.com/r/ {keyword}"
- Cross-posts and comments in existing posts
- Evaluate each: members, activity, promo_policy, relevance
- New communities default to tier=4 (watching)
- Dedup by
name, append via:
python3 SKILL_DIR/scripts/jsonl_ops.py append subreddits '<json>'
- Render:
python3 SKILL_DIR/scripts/jsonl_ops.py render subreddits
- Report: new entries added + current total
Where SKILL_DIR is two levels up from this file (the reddit-intel repo root).
