From b1ce15f3cc8edf23b28096f4545496c4472af36e Mon Sep 17 00:00:00 2001 From: Leo Vasanko Date: Mon, 21 Sep 2026 14:00:51 +0000 Subject: [PATCH] nav job mode: whole-menu titles as one nested list; Kimi Code API backend MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - translate.py: new "nav" job mode (Hello.modes opt-in) — the whole navigation hierarchy crosses as one nested Markdown list of pending titles, decomposed back by align_nav: item count/depth must match or the job is rejected wholesale (titles fall back to scoped jobs); items failing title checks individually are skipped to scoped jobs. Dispatched ahead of per-title jobs; a lone pending title stays scoped. - article jobs carry the already-translated menu title and parent title as contexts, so the injected heading can match the menu while the model may adapt the in-article title to the content. - llm_translator.py: nav mode + nav_prompt; article prompt takes the title/location context; API keys from per-provider env vars only (KIMI/MOONSHOT/OPENAI_API_KEY, each sent only to its own host; LLM_API_KEY generic) — no CLI flag, no config file; Kimi Code /coding endpoint support (sampling fields dropped, reasoning_effort from config, field-proven with k3-256k at low effort); errors include the response body; verbose per-job logging with the raw response incl. thinking (stripped from results); Kimi models announce all languages. --- AGENTS.md | 2 +- docs/llm-translation.md | 43 ++++++-- docs/localization.md | 27 ++++- pagerite/translate.py | 198 +++++++++++++++++++++++++++++----- scripts/llm_translator.py | 217 +++++++++++++++++++++++++++----------- 5 files changed, 386 insertions(+), 101 deletions(-) diff --git a/AGENTS.md b/AGENTS.md index baa3920..65c26ba 100644 --- a/AGENTS.md +++ b/AGENTS.md @@ -37,7 +37,7 @@ Pagerite is a CMS.
