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

jtbd 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 2mo 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.

Framework

Phase 1: Discovery — JTBD Analysis

1.3 JTBD (Jobs to Be Done) Analysis

"The unit of analysis is not the consumer, but the job the consumer is trying to get done." — Clayton Christensen

JTBD Three-Layer Coverage (quality check: cover all three layers):

A complete JTBD analysis covers all three layers explicitly: Functional (the task being completed), Emotional (how the user wants to feel during/after), and Social (how the user wants to be perceived). Producing only the Functional layer is the most common JTBD failure: Emotional and Social Jobs are routinely the real switching triggers, especially in B2B. If a single Persona genuinely has no meaningful Emotional or Social Job for the product, state that explicitly with one sentence of reasoning; do not silently omit the row.

JTBD Canonical Form (quality check: three-clause structure):

Every JTBD statement in every layer (Primary, Functional, Emotional, Social) is written as a complete three-clause sentence in the canonical form. All three clauses matter:

When [situation], I want to [motivation], so [outcome].

Failing examples (fragments inside a table cell, missing clauses):

  • ❌ "Quickly capture key takeaways" (missing When; missing so)
  • ❌ "Jot down ideas during commute" (missing I want to; missing so outcome)

Passing example (all three clauses present):

  • ✅ "When I've just finished reading an article and the key insight is still fresh, I want to capture one takeaway in 5 seconds, so weeks later I can still find it and connect it to a new idea."

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.
