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

win-loss-analysis 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 8d 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.

Win/Loss Analysis

Turn deal outcomes into actionable insights. Understanding why you win and lose is the fastest way to improve your sales process, coaching, and competitive strategy. This isn't about blame — it's about patterns.

Why This Matters

Most teams track win rate as a number but don't systematically learn from it. Win/loss analysis reveals:

  • Which competitors you beat and which beat you (and why)
  • What discovery patterns lead to wins vs. losses
  • Where deals stall and die in your pipeline
  • Which rep behaviors correlate with better outcomes
  • How pricing, timing, and stakeholder engagement affect close rates
