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

crucible 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 4d 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.

Crucible

A council of specialized personas debates one idea under structured conflict. The chair synthesizes into a verdict. Transcripts are saved to disk for second-brain reuse.

Use this when the cost of being wrong is high enough to justify convening 5-10 subagents. For one-lens exploration without a debate, use Solo mode. For tactical questions under five minutes of normal thinking, don't use Crucible at all.

When to trigger

Trigger on explicit user invocation only. Examples:

  • /crucible <idea> (Decision mode default)
  • /crucible --council <idea> or /crucible --quick <idea> (Council mode)
  • /crucible --pm <idea> (PM Daily mode)
  • /crucible --solo <persona> <idea> or natural language ("give me the First Principles read on X")
  • /crucible --existential <idea>
  • "Run this through the crucible: ..."
  • "Convene the crucible on ..."

Do not auto-trigger. This is an expensive skill and the user decides when it runs.

Five modes

The chair selects mode at intake based on the user's phrasing OR an explicit flag. Most daily use belongs in Council or Solo. Decision and Existential are for real decisions with real stakes.

Mode 1: Solo (single-persona lens, ~10-15 seconds)

Triggers: /crucible --solo <persona>, or natural language ("give me the First Principles read on X", "what does the Expansionist think about Y", "Track Record this for me").

Persona count: 1. No duels. No chair verdict. The chair's only job is persona-matching and returning the rubric output unchanged.

Use for: Exploration, not decisions. When you want one specific lens, not a debate.

Honesty check: If you find yourself reaching for Solo to avoid hearing the Contrarian, that's a signal to run Council mode instead.

Mode 2: Council (daily reflex, ~30-45 seconds)

Triggers: "council", "quick crucible", "gut check", "throw rocks at this", "poke holes", "sanity check", /crucible --council, /crucible --quick.

Bench: 5 personas, parallel openings only. No duels. No verdict beyond a one-liner.

  • Contrarian (Sonnet, NOT Opus at this tier to keep cost down)
  • First Principles (Sonnet at this tier)
  • Expansionist (Sonnet)
  • Outsider (Haiku)
  • Operator (Haiku)

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.
