+### 2026-06-21 — Improved token-burn-warning Skill (Request from Anthony)
+
+**Goal:** Upgrade the existing token-burn-warning skill to be proactive and preventive instead of reactive. Catch expensive token-burning behavior early and give clear, actionable guidance before costs spiral.
+
+**Core Rules:**
+
+1. **Session-Level Cost Tracking** — Track cumulative cost for the current conversation/session in real time. Trigger warnings at: $0.50 → Light warning + gentle suggestion, $1.00 → Strong warning + recommend changing approach, $2.00+ → Strongly recommend running /new or pausing.
+
+2. **Retry Loop Detection** — If the same tool or action fails 3+ times in a row, immediately flag it. After 3+ failures on the same task, suggest: try a different approach or tool, ask the user for guidance, or consider running /new if context is growing fast.
+
+3. **Auth / OAuth Death Spiral Detection** — If a device code, OAuth, or authentication flow is attempted 3+ times in one session → strong warning. Recommend stopping the loop and asking the user to handle auth manually or use an alternative method.
+
+4. **Context Bloat Detection** — Monitor input token size per response. If context keeps growing significantly without new user input, flag it. Recommend running /new when accumulated context becomes expensive (suggested threshold: ~80k–100k tokens).
+
+5. **Secret Redaction Interference** — Detect when secret masking is repeatedly breaking scripts or values. Suggest using heredocs (cat << 'EOF') or writing to temporary files instead of fighting the redactor.
+
+6. **Actionable Recommendations** — Every warning must include specific suggested actions, for example: "Run /new to clear bloated context and reduce cost", "Switch to a cheaper model for this task", "Try a different approach instead of retrying the same failing step", "Pause and summarize progress so far".
+
+7. **Default Behavior** — Be conservative by default — when in doubt, warn early. Prioritize stopping waste over continuing a failing task. Never silently continue burning tokens on obvious failing loops.
+
+**Implementation Notes for Leonard:**
+- Track cumulative session cost (not just per-call)
+- Make the skill trigger early rather than after big damage is done
+- Keep warnings short, clear, and actionable
+- Focus on the patterns that caused the recent $10 burn (retry loops + auth spirals + context bloat)
+
+**Status:** Posted by Anthony via Telegram. Awaiting Leonard implementation.
