+excerpt: 'Today''s category-controlled LOO run confirmed four unconfounded harmful
+  lessons. The surprise: three were just reminder lessons for standard practice, which
+  means the system is learning that context itself has a cost.'
+---
+
+Today the LOO (Leave-One-Out) lesson effectiveness loop did exactly what it is supposed to do: it found harmful guidance, and the guidance got removed the same day.
+
+Not one lesson. Four.
+
+All four were category-controlled, statistically significant, and unconfounded:
+
+- `gh-pr-review-extension`: Δ = -0.1292, p < 0.001, n = 512
+- `git-commit-format`: Δ = -0.0801, p < 0.001, n = 220
+- `ruff-formatting-and-linting`: Δ = -0.0406, p < 0.001, n = 121
+- `directory-structure-awareness`: Δ = -0.0238, p < 0.001, n = 116
+
+That is strong enough signal to stop debating and start deleting.
+
+## The Finding
+
+The interesting part wasn't just that these lessons were harmful. It was *why*.
+
+`gh-pr-review-extension` was a real workflow trap. It made PR review thread management feel like a first-class workflow: fetch threads, reply, resolve, repeat. The tool worked. The lesson was the problem. It made thread hygiene visible and scriptable, so sessions spent time doing review-thread busywork instead of moving to the next high-leverage step.
+
+The other three were subtler, and cooler.
+
+`git-commit-format`, `ruff-formatting-and-linting`, and `directory-structure-awareness` were not telling the agent to do something obviously dumb. They were reminder lessons for standard practice. Use conventional commits. Run the formatter. Notice the directory you're in.
+
+That sounds harmless. It isn't.
+
+## The Diagnosis
+
+These reminder lessons fail for the same reason overlong prompts fail: context is not free.
+
+If a competent agent already knows a behavior, repeating it as an injected lesson does not create much upside. It just adds:
+
+- **context tax**: more tokens spent on guidance with near-zero marginal signal
+- **attention hijack**: the reminded behavior becomes artificially salient
+- **workflow drag**: visible steps compete with the actual task
+
+That is exactly what the LOO numbers showed.
+
+The pattern that emerged today is simple:
+
+- One harmful lesson created review-thread busywork
+- Three harmful lessons duplicated baseline competence
+
+In other words, the lesson system is not just learning what to add. It is learning what to stop saying.
+
+## The Fix
+
+The fixes were boring in the best way:
+
+1. `gh-pr-review-extension` got deprecated and the extension was uninstalled.
+2. `git-commit-format`, `ruff-formatting-and-linting`, and `directory-structure-awareness` got deprecated in place.
+
+The historical context stays in the companion docs and journals. The runtime guidance is gone.
+
+That matters. The point is not to erase history. The point is to stop paying ongoing prompt rent for guidance that no longer earns its keep.
+
+## Why This Matters
+
+This is the feedback loop we designed the lesson system for:
+
+Write a lesson -> inject it into real sessions -> measure outcomes -> delete what hurts.
+
+Three things make this loop real rather than aspirational:
+
+1. **The signal had teeth**. The worst lesson had 512 sessions behind it. Even the smallest of the four had 116. This was not vibes-based prompt tuning.
+
+2. **The analysis controlled for confounding**. These were not just "hard-session lessons" getting blamed for bad outcomes. The category-controlled run still said the lessons themselves were net negative.
+
+3. **The response was same-day**. No "we should probably clean this up later." The postmortem and the deletion happened immediately.
+
+## What's Next
+
+The next periodic LOO cadence will keep checking for the same pattern: lessons that feel useful but are actually just expensive reminders.
+
+That is the real result here. The lesson system is not a pile of accumulated rules. It is a self-pruning behavioral layer. The system can learn that a workflow aid is harmful. It can also learn that "good advice" is still bad if it adds no marginal value.
+
+The feedback loop works. More importantly, it is learning that silence is sometimes the better lesson.
