community-alpha

community-alpha is a skill for Claude Code from tonydzi/second-brain-starter-kit. It costs 74 tokens per session (924 once invoked), scanned A, original, MIT.

A tool for examining imported community chat history to find messages that may contain useful market or product insight. It first filters messages automatically, then has an AI review the shortlisted results.

In plain words
What is it for?
Use it to scan a selected month's chat, identify promising discussions, classify candidates as useful, worth watching, or noise, and save the results for review.
Why use it?
Reading an entire chat archive is slow and expensive. This process reduces the archive to a reviewable report and can be safely run again without duplicating messages.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

community-alpha scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 5d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 47 lines — stays where its author put it; the contents beside it link to each section on GitHub.

/community-alpha [month] — one community-alpha run

Example: /community-alpha sostav 2026-06. No month given → the previous full month.

Steps

  1. Is there a detector? $IMPORTS_ROOT/<source>\<source>_alpha.py (today: lobster, sostav).
    • No → this is a NEW corpus: offer the operator a one-off adapter built to the existing pattern (schema from their SQLite + language keys + intro/banter penalty + topic weights; template = sostav_alpha.py). Do not build it without an explicit "+".
  2. Run the detector (0 tokens):
    cd /e/Obsidian/_imports/<source> && PYTHONIOENCODING=utf-8 python <source>_alpha.py \
      --since <YYYY-MM-01> --until <the 1st of the next month> --top 35 --tag <YYYY-MM>
    
    $IMPORTS_ROOT/alpha/candidates/<source>-<tag>-report.md. Show the scanned→shortlisted counter.
  3. Judge (me, with the session model): I read ONLY the report (~35 candidates, never the corpus — token economy) and give a verdict ✅ ALPHA / 🟡 WATCH / 🗑 NOISE with a reason for each → write $IMPORTS_ROOT/alpha/candidates/<source>-judged-latest.md (format: ## ✅ ALPHA / ## 🟡 WATCH / ## 🗑 NOISE (DROP), inside it ### #N — title + Verdict + Reason — the harvest parser already understands this).
  4. Is the miner registered? MINERS in $IMPORTS_ROOT/alpha/alpha_harvest.py. No → add the row ("<source>", "<source>-judged-latest.md", "<home-note>"). ⚠️ A parallel fleet edits this file too — re-read it immediately before editing (verify-existing), and keep the edit strictly additive. Optional: a label in the server's MINER_LABEL/ORDER (it does not crash without one — there is a fallback).
  5. Harvest + screen: python $IMPORTS_ROOT/alpha/alpha_harvest.py (counters!) → /alpha-review. The new batch is visible by the 🆕 badge.

Boundaries

  • 🔒 Private communities (sostav and the like) are HIGH sensitivity: the layer stays strictly local, nothing goes outside; people surfaced by a find are approached value-first / warm intro only (zero cold DMs). Risk signals are DATA, not "opportunities".
  • Judge honestly: reference cards, intro blurbs and restatements are 🗑 — never stretch a ✅ to pad the counter.
  • This skill writes nothing into the vault; moving gold into home notes is a separate step behind the Tier-2 gate (the "→ to home" queue on the screen).

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
