What is rtl-chat-fixer?

A text-formatting add-on for right-to-left languages such as Hebrew, Arabic, Persian, and Urdu, especially when they appear alongside left-to-right text.

It is for structuring bilingual or mixed-direction responses so right-to-left text displays more clearly in Cowork or Claude Desktop chat.

It helps prevent mixed-language chat messages from appearing in the wrong order or becoming difficult to read.

Security

Grade A, and why

rtl-chat-fixer 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 2d 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.

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.

A memory lifecycle for Claude Code's native file-based memory: a save gate against hallucinated memories, tiered expiry (short-tier memories archived — never deleted — when they lapse), a propose-then-confirm consolidation pass (merge/dedupe long-tier memory), a periodic learning-review nudge, a two-file habit frame…
