# Week of July 13, 2026

> Weekly Arka changelog: council deliberation, quiz practice, timezone conversion, slides finetuning, self-improve loop, and CI fixes.

## New features

* **[Arka Council](/guides/council).** Multi-persona deliberation — Socrates, Elon, and Feynman answer the same question independently, then Arka synthesizes consensus, tension, and a verdict.
* **[Quiz practice](/guides/quiz-practice).** Infinite quizzes on any topic with per-topic memory so questions never repeat.
* **[Timezone conversion](/guides/timezone-convert).** `arka convert 9am PDT to IST` and natural-language date/time conversion; disambiguates from currency `convert`.
* **[Open URL](/guides/open-url).** `arka open youtube` opens sites in your default browser (distinct from `play_youtube`).
* **[Interesting facts](/guides/interesting-fact).** Lightweight trivia without web search — `tell me something interesting`.
* **[Self-improve loop](/guides/self-improve).** `arka self improve` analyzes the codebase and optionally applies fixes with `--apply`.
* **[Operation modes](/guides/operation-modes).** `arka mode debug` for routing traces; default `agent` mode keeps output clean.
* **[Compose slides](/guides/compose-slides).** Executive/pitch/academic style presets, action titles, validated pptx export with markdown fallback.
* **Frontend visual loop.** Arka can now inspect its own frontend screenshots, judge polish, and retry a build command for up to N passes.
* **Domain agents.** Astronomy, metallurgy, fact-check, science flow, Harvard ARK biomedical KG, repo context indexing.
* **Provider CLI.** `arka provider list/set/show/models` with live OpenRouter autodetect.
* **CSV/TSV table previews over MCP.** Clean structured previews for connected MCP clients.

## Improvements

* LLM fallback skips vLLM unless explicitly configured; traces hidden unless debug mode.
* OpenRouter credit errors fall back to Gemini/Groq when keys are present.
* Self-improve and goal agent use clean user-facing output (no llm.txt dumps in normal mode).
* CI fixed: clipboard routing in `ai_only` mode, ruff lint clean across `src/` and `tests/`.

## Docs

* New guide pages for all features above; orphan guides (bookmarks, clipboard-history, docker-status, repo-health) added to navigation.
