-2. **Check schedule**: `tensor.schedule()` returns list of ScheduleItems
+2. **Check schedule**: `tensor.schedule()` returns list of ExecItems
 3. **Trace graph rewrites**: Use `VIZ=1` or add print in PatternMatcher callbacks
 4. **Find UOps by type**: `[u for u in uop.toposort() if u.op is Ops.SOMETHING]`
 
 ## Workflow Rules
 
 - **NEVER commit without explicit user approval** - always show the diff and wait for approval
+- **NEVER amend commits** - always create a new commit instead
+- Run `pre-commit run --all-files` before committing to catch linting/type errors
 - Run tests before proposing commits
 - Test with `SPEC=2` when modifying UOp-related code
 
+## Auto-generated Files (DO NOT EDIT)
+
+The following files are auto-generated and should never be edited manually:
+- `extra/assembly/amd/autogen/{arch}/__init__.py` - Generated by `python -m extra.assembly.amd.dsl --arch {arch}`
+- `extra/assembly/amd/autogen/{arch}/gen_pcode.py` - Generated by `python -m extra.assembly.amd.pcode --arch {arch}`

+Where `{arch}` is one of: `rdna3`, `rdna4`, `cdna`
+
+To add missing instruction implementations, add them to `extra/assembly/amd/emu.py` instead.

+### Readability Over Speed
+Don't add complexity for marginal performance gains. Simpler code that's slightly slower is often better:
+```python
+# BAD: "optimized" with extra complexity
+if has_afters:  # skip toposort if no AFTERs
+  after_map = [(u, u.buf_uop) for u in big_sink.toposort() if u.op is Ops.AFTER]

+# GOOD: simple, always works

+```
+The conditional check adds complexity, potential bugs, and often negligible speedup. Only optimize when profiling shows a real bottleneck.
