Summary

AI summary

Fixed session usage delta always reporting 0.0pp by ensuring the start snapshot is written only once.

Full changelog

What's new

fix(session-end): session usage delta was always 0.0pp — _fetch_live_usage() was overwriting the session-start snapshot on every mid-session refresh call, making start == end by session close. Snapshot now written only once, after the delta is reported.
fix(session-start): session_spend.json now resets at each session start so top model reflects the current session only (hook v15)
feat(session-start): p50 latency hint in session banner (hook v14)
feat(hooks): plan-nudge.py — injects Plan Mode reminder for complex multi-file prompts
feat(hooks): test-nudge.py — reminds to run tests after editing source files
feat(hooks): version-guard.py — blocks on Edit/Write when version files diverge
feat: /insights skill for session gap analysis
feat: /release skill with full release checklist
feat: docs/decisions.md decision log
docs(CLAUDE.md): deadlock warning, Python-first, env setup, uv run pytest, version sync

About ypollak2/llm-router

Subscription-aware LLM router for Claude Code. Routes tasks to 20+ providers (OpenAI, Gemini, Groq, Ollama, Codex) based on complexity classification, Claude subscription pressure, and cost. Free tasks stay on Claude subscription; expensive tasks fall back to the cheapest capable model. Includes 30 MCP tools, 6 auto-routing hooks, semantic dedup cache, prompt caching, daily spend cap, and a live web dashboard.
