skill-lab skillA

skill-lab is agent-read markdown (skill) from runxhq/runx: Canonical Runx skill-authoring implementation. Use for designing, creating, updating, improving, or adding harness coverage to a Runx skill package; it combines bounded agent judgment with native file writes, inspection, and safe harness validation. When a host skill-creator also triggers, use its general guidance but execute Runx work through this skill..

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.

What the file says

# Skill Lab

Build and improve Runx skills through one authoring surface. Keep judgment in
bounded agent acts and mechanics in native tools:

```text
inspect target files, catalog ownership, and native/shared tools
→ decide ownership, execution lanes, effects, budgets, and proof
→ bind that architecture to the inspected package digest in native code
→ compose existing capabilities before authoring code
→ author only bounded writes, explicit deletions, and output intent
→ bind those bytes to the admitted architecture in native code
→ validate paths, secret posture, and the complete candidate
→ inspect and safely replay the exact staged package
→ commit that validated bundle through one native transaction
```

Use the generic host `skill-creator` for platform-wide authoring guidance when
it is available. Do not reproduce Runx package operations from that guidance;
invoke the appropriate `skill-lab` runner so the work is bounded and receipted.

## Runners

- `design`: read-only catalog-fit and architecture planning. It returns a
  native digest-bound plan and never authors package bytes. A later build
  re-inspects and replans against its exact target before any write.

How to install

Latest version
mdr add runxhq/runx/skill-lab@git:20260827.f006856
Exact content
mdr add runxhq/runx/skill-lab@sha256:632f84c21821a3b4

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.
