harness-boundary SKILL.md skillA
This file is byte-identical to the first copy the registry indexed. Same content hash, so the same checks give both the same grade.
harness-boundary from shimo4228/akc-cycle is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Design lens: which layer a harness mechanism belongs in, and whether it outlives the next model or runtime.
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
# harness-boundary — a design lens that treats as assets only what survives discarding the harness "The harness is the asset" is only half right. Harness logic that compensates for model-specific weaknesses goes stale with each model generation, and the runtime (tool execution, permissions, state, retry, agent loop) is being standardized and replaced. What remains are **other layers mixed into** the harness. This skill raises the questions for separating that mixture when a mechanism is added, changed, or reviewed. This is not an enforced architecture but a lens for judging asset boundaries, portability, and obsolescence. ## Core principles - Put model capability in the model. Do not reimplement it in the harness - Put procedural knowledge in skills - Keep values and responsibility boundaries explicit and inspectable - Put the definition of quality in evals - Put domain knowledge and history in data / memory - Keep the runtime as thin and swappable as practically possible And: **do not optimize to preserve the harness. Optimize to preserve what should survive swapping the harness.** When a new model makes existing logic unnecessary, that is not a design …

How to install
mdr add shimo4228/akc-cycle/harness-boundary@sha256:ae5ba247095aa469The line at the top of this page pins the label git:20261101.1c68dc8, 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.
