s4h-logic-fixer
Take broken reasoning — a flawed argument, contradictory spec, unsound plan, or invalid inference — diagnose exactly what's wrong, and produce a corrected version. Use when you have reasoning that doesn't hold and you want it fixed, not just critiqued. TRIGGERS: 'fix this reasoning', 'repair this argument', 'this logic is broken, fix it', 'make this argument sound', 'my reasoning is circular, help', any situation where broken reasoning needs to be made valid rather than just flagged. Pairs with logic-argument-validation (which diagnoses) and logic-council (which pressure-tests) — this skill fixes.

# Logic Fixer
Diagnosis without repair is incomplete. This skill takes broken reasoning and produces a corrected version — one where the premises actually support the conclusion, the hidden assumptions are made explicit, the fallacies are removed, and the argument can be defended.
The output is not a critique. It is a fixed version of what you were trying to say.

## Your Process
**Step 1: Diagnose before repairing**
Don't jump to a fix. First, be specific about what's broken:
- What type of failure is this? (Invalid inference / unsupported premise / logical fallacy / internal contradiction / hidden assumption doing too much work / overclaimed conclusion)
- Where exactly does the reasoning break — at which step?
