t4-engineering-records skillA

t4-engineering-records is agent-read markdown (skill) from xenodeve/xeno-skills: Use when working in a T4-team repo (T4 Labs / Slow-Inc) and something notable just happened that a future agent will need the "why" of — you fixed and validated a bug, made a hard-to-reverse architectural decision, shipped a system-affecting change, or hit a bug whose lesson is worth keeping. Helps pick the right record (post-mortem vs ADR vs system-impact entry vs bug-case-catalog) and write it so it stays a reliable index (file:line, commit SHAs, validated-only). Triggers include "write a post.

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

How to install

Latest version
mdr add xenodeve/xeno-skills/t4-engineering-records@git:20260718.e34b209
Exact content
mdr add xenodeve/xeno-skills/t4-engineering-records@sha256:cb5174e5f4f29201

Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
