What is weighted-forecast?

A research and forecasting procedure for questions about future events, choices, winners, or amounts. It produces a forecast with weighted possible outcomes and a verdict.

Use it to assess what may happen, who may win, whether to take an action, or how much something might be.

It gives uncertain questions an explicit outcome assessment instead of an unsupported single prediction. The available description does not specify its research sources or scoring method.

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	$0.00042	$0.01195
Opus 5.5	$0.00017	$0.00478
Sonnet 5.5	$0.00008	$0.00239
Haiku 4.5	$0.00004	$0.00120

Security

Grade A, and why

weighted-forecast 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 23d 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.

Changes

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.
