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

aarrr-pirate-metrics 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.

AARRR — Pirate Metrics

Overview

AARRR is a five-stage funnel framework for diagnosing where a product is losing users and revenue. Each stage maps to a measurable rate. Fix the worst-leaking stage first — patching acquisition while retention is broken is pouring water into a cracked bucket.

[Acquisition]
     |  % who visit / sign up
     v
[Activation]
     |  % who reach first value moment
     v
[Retention]
     |  % who come back
     v
[Referral]
     |  % who invite others
     v
[Revenue]
     |  % who pay / expand
     v
  GROWTH

Core Components

Acquisition

How do users find you? Channels: SEO, paid ads, social, content, outbound, partnerships.

  • Key metric: visitors, sign-ups, or installs per channel
  • Measure cost per acquisition (CPA) and channel mix to avoid over-dependence on one source

Activation

Do users experience the core value before they leave? This is the "aha moment" — the first action that predicts long-term retention.

  • Key metric: % of new users who complete the activation event within N days
  • Example activation events: sent first message, created first project, ran first report

Retention

Do users come back? This is the most important stage — without it, every other investment leaks.

  • Key metric: Day-7 / Day-30 retention rate; or weekly/monthly active user (WAU/MAU) ratio
  • A retention curve that flattens above 0% indicates a sustainable product

Referral

Do users bring others? Referral is the multiplier on every other stage.

  • Key metric: Net Promoter Score (NPS) and viral coefficient (invites sent × invite conversion rate)
  • Viral coefficient > 1.0 means the product grows without paid spend

Revenue

Do users pay, and do they expand? Revenue validates that value is real.

  • Key metric: MRR, ARPU, LTV, LTV:CAC ratio
  • A healthy ratio is LTV ≥ 3× CAC; payback period under 12 months for SaaS

How to Apply

Step 1 — Instrument each stage

Before analyzing anything, confirm you can measure each funnel step. Map one primary metric per stage. If you cannot measure it today, define the event and build the tracking first.

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.
