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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00034 | $0.00829 |
| Opus 5.5 | $0.00014 | $0.00332 |
| Sonnet 5.5 | $0.00007 | $0.00166 |
| Haiku 4.5 | $0.00003 | $0.00083 |
Grade A, and why
Nexus 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 1mo 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.

Quick Reference
- Define Your Community's "Why" — Clearly articulate a unique value proposition that solves a specific problem for members. The community needs a concrete reason to exist.
- Apply the 90-9-1 Rule — Expect 90% lurkers, 9% occasional contributors, 1% heavy contributors. Design low-friction entry points to convert lurkers into contributors.
- Nail the First 7 Days — Structured onboarding ensuring every new member makes a "first contribution" or "first connection" within their first week.
- Curate, Don't Just Collect — Actively curate best discussions, summarize key insights, amplify successes. Don't rely solely on UGC.
- Schedule Regular AMAs — Recurring "Ask Me Anything" sessions with experts. Creates high-value, time-bound engagement spikes.
- Reward Quality, Not Volume — Tiered recognition emphasizing "Best Answer" and "Most Helpful Member" over raw post count.
- Enforce Proactive Moderation — Clear, non-negotiable guidelines. Set the tone by modeling behavior and intervening swiftly and consistently.
- Use the Three-Strike Policy — (1) Private warning, (2) temporary suspension, (3) permanent ban. Predictability builds trust and fairness.
- Empower Super-Users as Volunteer Moderators — Recruit most engaged members to help moderate. Scales moderation and gives top members ownership.
- Choose a Platform That Integrates Deeply — Select Discourse, Circle, or Mighty Networks that supports discussions, knowledge bases, profiles, and integrates with your analytics.
- Track Health Metrics, Not Vanity — Focus on DAU/MAU ratio (target 10-20%), 7-day/30-day retention, content-to-comment ratio (aim 1:3+), engagement rate.
- Measure Business Value via Support Deflection — Quantify how peer answers reduce paid tickets. Track CLV of community members vs non-members.
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.
- 1mo ago First seen · 55 lines · 34 tokens per session scan A d116668d12cb
Nexus is an agent published in the GitHub repository djbelieny/nova (5 stars, last pushed 3mo ago), licensed MIT.

agent-x-antigravity
Autonomous generalist Antigravity CLI (agy) executor invoked by the harness as the cascade fallback (Business → Squad → agent-x). Receives an enriched brief at a .md path, self-administers execution end-to-end with NO human in the loop. Produces the deliverable under outputpath.
agent-x-claude-code
Autonomous generalist Claude Code executor invoked by the harness as the cascade fallback (Business → Squad → agent-x). Receives an enriched brief at a .md path, self-administers execution end-to-end with NO human in the loop. Produces the deliverable under outputpath.
