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

challenge 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 9d 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

Stress-test this decision: $ARGUMENTS

Be adversarial. The goal is to find flaws, not confirm the decision. Agreement is not useful here.

Step 1 — Restate What exactly is being decided? State it precisely, not as interpreted.

Step 2 — Assumptions List 3–5 core assumptions this decision depends on. What must be true for it to work?

Step 3 — Failure modes Give 3 specific, concrete scenarios where this decision leads to a bad outcome. Be specific — name the situation, not a vague risk category.

Step 4 — Strongest alternative What is the best competing option? Describe it concretely. Why might someone prefer it?

Step 5 — Blind spots What has this analysis not considered? What context, constraint, or stakeholder is missing?

Step 6 — Verdict One of: PROCEED / RECONSIDER / NEEDS MORE INFO One sentence explaining why.

Output format:

DECISION: [restated precisely]

ASSUMPTIONS:
1. [assumption]
2. [assumption]
3. [assumption]

FAILURE MODES:
1. [scenario] — [consequence]
2. [scenario] — [consequence]
3. [scenario] — [consequence]

STRONGEST ALTERNATIVE: [description + why someone would choose it]

BLIND SPOTS: [what's missing from this analysis]

VERDICT: [PROCEED / RECONSIDER / NEEDS MORE INFO]
REASON: [one sentence]

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.
