library-classic SKILL.md skillA
library-classic from feilipu/8085-skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

z88dk classic library world: libsrc/target and classic trees, multi-CPU (8080/8085/gbz80/…), fgets_cons line input, hybrid CRT traps, isolation from newlib. Use when working on classic clib, 8085 products, or hybrid consoles.
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
# Library — classic
## 1. Two library worlds (do not blur)
| World | Home | CPUs | Typical product |
|-------|------|------|-----------------|
| **Classic** | `libsrc/target/<name>/` (historic fcntl/stdio/gfx) + `libsrc/classic/` | Z80, IXIY, Z180, **8080**, **8085**, gbz80, … | `*_clib.lib`, `cpm8085_clib.lib`, … |
| **Newlib** | Was `libsrc/newlib/target/<name>/`; migrated → `libsrc/target/<name>/` beside classic | **Z80-class** (`-clib=new` / `sdcc_ix` / `sdcc_iy`) | `lib/clibs/{sccz80,sdcc_ix}/<target>.lib` |
**Hard rules**
1. Do **not** merge classic and newlib **stdio cores** or **fcntl `open` owners** in one link without a designed bridge.
2. Prefer sharing **device / thin driver** layers, not cores.
3. **CLIB** selects newlib; machine **SUBTYPE**s usually stay classic-owned (esp. CP/M’s 150+ machines).
4. After a path move, put the target name in `MIGRATED_TARGETS` in `libsrc/newlib/Makefile` so builds use `../target/<name>`.

How to install
mdr add feilipu/8085-skills/library-classic@sha256:047c7d2f781c2485The 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.
