reddit-sub — Discover Subreddits
Find Reddit communities where your target users live and discuss pain points.
Tool Rules
- DO NOT use built-in WebSearch for Reddit (blocked by Anthropic's crawler)
- MUST use
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
Reads .reddit-intel.json from project root. If not found, tell user to run /reddit-intel-init.
Schema: subreddits.jsonl (unique key: name)
{"name": "r/ClaudeAI", "tier": 1, "members": "451K", "activity": "high", "promo_policy": "discussion OK", "relevance": "primary", "strategy": "Pain-point replies, technical discussions", "added": "2026-02-06"}
tier values: 1 (core) / 2 (high relevance) / 3 (general/niche) / 4 (watching)
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).
