What is x-twitter-engine?

A daily workflow for engaging on X, formerly known as Twitter, through replies, timely posts, and original threads. It includes human review and is designed for repeated daily use.

It helps plan replies to selected accounts, react to news, and develop original discussion threads on X.

It gives a structured way to stay active and respond to relevant conversations instead of deciding what to post from scratch each day.

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	$0.00051	$0.04929
Opus 5.5	$0.00020	$0.01972
Sonnet 5.5	$0.00010	$0.00986
Haiku 4.5	$0.00005	$0.00493

Security

Grade A, and why

x-twitter-engine scanned grade A with 1 finding 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

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.
