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.

Model	Per session	Once invoked
Fable 5.1	$0.04465	$0.04465
Opus 5.5	$0.01786	$0.01786
Sonnet 5.5	$0.00893	$0.00893
Haiku 4.5	$0.00447	$0.00447

Security

Grade A, and why

eastmoney-monthly CLAUDE.md 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.

Eastmoney Monthly Chart AI Analysis Assistant

Project Charter: .claude-charter.md (must read before every task)

Chrome MV3 extension, injected into Eastmoney stock pages (quote.eastmoney.com), analyzing stock trends via LLM API. Local personal use only, not published to Chrome Web Store.

Regime-Adaptive MoE Architecture (designed 2026-06-05)

Design Principles

No single point of failure: Any component failure does not affect the whole
LLM isolation: LLM is outside the signal chain, only does interpretation
Mechanical lookup table: regime→weights are hardcoded, not passing through any model
3D expert grid: Expert = regime × scale × perspective intersection, not model names

Expert Registry (3D key)

expert_registry = {
    # key = (signal_id, regime, scale)
    # status: verified | anti_signal | pending_validation | pending_feature

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.
