about

nx_ctxcost.nx -- CONTEXT-COST ADVISOR (operator 2026-07-21: 'make nishi SEE the cost if it can, flag to you what we should do as you work a workstream'). MEASURED real usage 2026-07-21: 96pct of spend at >150k context; 71pct from nishi MCP results that STAY in context re-read every turn. So: given the current context_pct (relayed from the Claude Code usage banner -- nishi can't read live context, so the caller feeds the number it CAN see), advise CONTINUE / COMPACT-SOON / COMPACT-NOW from data-driven thresholds in ctxbudget- (rule-11, tune without code). Reminds of the cheap-reboot: /clear then nx_seat boot = ~1KB (state lives in planes). Composes nx_sovjson_lib (sj_*) = OO, 5th base consumer. advise <context_pct> [ws] [ctxbudgetprefix] -> verdict JSON | selftest [tmpbase] ctxbudget- row = id threshold_pct verdict action reason (5-col policy plane; pick highest thr <= pct). license_tier: ORIGINAL No hw writes (Rule 26). expect_exit: 0
