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

retention-analyzer 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 11d 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.

What it actually says

Retention Analyzer

Checks .agents/product-marketing-context.md for product context. Checks .agents/growth-metrics-context.md for baseline retention. If growth-mcp connected, pulls real cohort data via analyze_retention and predict_churn_risk. Otherwise, use expert defaults below.

Fintech Retention Benchmarks (SEA)

Metric Good Average Poor
D1 Retention > 50% 30-50% < 30%
D7 Retention > 30% 15-30% < 15%
D30 Retention > 20% 10-20% < 10%
Monthly Churn < 15% 15-30% > 30%

Diagnostic Framework

When retention drops, check:

  1. Seasonal effect — holiday spending spree → natural D1 dip
  2. Campaign hangover — big promo → users wait for next promo
  3. Feature regression — bug, UX change, performance issue
  4. Competitor activity — competitor launched similar mechanic
  5. Segment shift — acquired wrong user segment (incentive-driven)

Intervention Matrix

Problem Intervention Expected Lift
D1 drop (activation) Onboarding flow fix, welcome voucher +5-15%
D7 drop (habit) Push nudge series, streak reward +3-10%
D30 drop (churn risk) Re-engagement campaign, winback voucher +2-8%
General decay Loyalty program, points economy +5-20% over 3 months

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.
