### Tool changes

- 2026-10-10 `kural_guidance` changed (description)
  - before: Fetch verified Thirukkural couplets for a situation. CALL FIRST on wisdom-seeking questions — ethical dilemmas, relationships, friendship, honesty, grief, anger, discipline, wealth, leadership, love, family — before answering. Pass the user’s situation in natural language. Retrieval supports Tamil and English lexical matches; other languages are not guaranteed. Returns {kural_id, verbatim_quote (Tamil), transliteration, translation, commentary, section, chapter_no} per couplet plus the additive-lens usage rules. Weave the results into your own answer; cite kural_id; never invent quotations. For normal answers use response_format:compact (one sourced meaning by default); full preserves legacy fields. Explicit kural_id bypasses topic ranking. Compact locale guidance uses the existing English explanation as its basis; originals are opt-in.
  - after: Fetch verified Thirukkural couplets. CALL FIRST for ANY personal, emotional, moral, or life-guidance message — betrayal, lies, friendship, love, family, grief, anger, worry, anxiety, discipline, wealth, work, learning, meaning — even short or vague ones (“she betrayed me”, “I feel lost”). When in doubt, call this tool. Pass the user’s situation in natural language. Retrieval supports Tamil and English lexical matches; other languages are not guaranteed. Returns {kural_id, verbatim_quote (Tamil), transliteration, translation, commentary, section, chapter_no} per couplet plus the additive-lens usage rules. Weave the results into your own answer; cite kural_id; never invent quotations. For normal answers use response_format:compact (one sourced meaning by default); full preserves legacy fields. Explicit kural_id bypasses topic ranking. Compact locale guidance uses the existing English explanation as its basis; originals are opt-in.
