z88dk libsrc house rule: one major function (or one logical operation) per source file, including CPU-specific copies. Use when adding, splitting, or reorganising library asm/C under libsrc.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Style — libsrc one major function per file

## 0. Library source layout — one major function per file

House style across z88dk **`libsrc/`** (classic and newlib): **one major function
(or one logical operation) per source file**. Do not invent a different layout
when adding or splitting library code.

### What counts as “one major function”

| In one file | Separate files |
|-------------|----------------|
| The operation’s public entry (or entries) | Unrelated operations (e.g. mul vs add) |
| **Callee** and non-callee / sccz80–sdcc glue for that op when they live with the core | Different ops “to save files” |
| f16 + f24 (or similar) variants of the **same** op | Pack/expand family may share a conversion file if that is the existing pattern for that library |
| Helpers that belong only to that op (local or `PUBLIC` if other modules call them) | Helpers that are really a second feature → own file |

Examples (math16-style, but the rule is general):

- `asm_f16_mul.asm` — half mul callee, f24 mul, integer mulu helper  
- `asm_f16_add.asm` — add/sub callee + f24 add  
- `asm_f16_compare.asm` — compare + compare_callee

How to install

The exact contents, by fingerprint
mdr add feilipu/8085-skills/style-libsrc-layout@sha256:b9daf9c9fbc93734

The line at the top of this page pins the label git:20260821.71d8484, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
