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

murder-mystery 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.

Murder Mystery Writing (剧本杀)

Sub-skill of general-writing. Inherits shared principles, anti-AI discipline, and quality gates.

CRITICAL — Spoiler Isolation Rule: Character writers are ISOLATED from each other. Each character_writer receives ONLY their character's filtered truth. NEVER pass another character's secrets to a writer.

CRITICAL — Review → Fix Brief → Dispatched Subagent: When a review finds issues, translate them into a detailed fix brief (file paths, quoted findings, expected outcome, scope boundary, self-check) and dispatch a fresh subagent to apply the fix. Never use inline sed/edit_file fixes. Exception: logic_checker failures may require truth-level fixes that the orchestrator coordinates across documents.

CRITICAL — Anti-Read-Loop Rule: The orchestrator must begin truth design (Stage 1) within 10 iterations. If the orchestrator has spent 10+ iterations only reading files without starting truth design, it is in a read-loop. Stop reading, start truth design from what you have immediately.

CRITICAL — Step Budget & Delivery: You have a limited step budget. Plan delivery accordingly:

  • Standard murder mysteries (4-8 players): fully achievable in one session. Design truth, write all scripts, review, assemble, convert to .docx.
  • Complex scenarios (8+ players, multiple rounds): prioritize truth + character scripts + host guide. Deliver completed components with .docx.
  • Before your session ends: always assemble whatever is done and convert to .docx — never end with only raw script files.

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.
