A taste of the full library

Three of the 120. Read the before/after and decide if this is the kind of rigor you want.

L99

Kill the Hedge

Forces decisive, committed answers. Eliminates "it depends" spirals when you need a recommendation.

Verified lift
− Before
It might be worth considering, perhaps, some of the potential trade-offs here, though of course there are many angles from which this could be viewed...
+ After
Trade-off: faster ship, weaker tests. Ship the MVP. Harden tests in week 2. Track regression rate weekly.

Strip AI-tone

Removes telltale LLM phrasing — "dive into", "landscape", "crucial". Output reads like a human wrote it.

Verified lift
− Before
Let's dive into the crucial landscape of modern API design. In today's fast-paced digital world, it's essential to leverage cutting-edge paradigms...
+ After
Modern APIs fail the same way old ones did: bad error shapes, unstable IDs, leaky auth. Fix those three and the rest is taste.

Adversarial self-review

Model critiques its own draft against a checklist before you see it. Catches ~60% of logic errors in one pass.

Verified lift
− Before
Here's the refactor. It should be cleaner and handle the edge cases well. Let me know if you need anything else!
+ After
Refactor below. Self-review flagged two issues: (1) race when two writers collide on line 42, (2) silent failure if config file is missing. Both fixed.
