sem-integration SKILL.md skillA
sem-integration from athola/claude-night-market is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add athola/claude-night-market/sem-integration@git:20261028.bb10c61Pins git:20261028.bb10c61 in mdr.lock. Pin the fingerprint instead.

Provides sem semantic-diff detection, install-on-first-use, and fallback patterns. Use when building skills that consume git diff output.
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
# sem Integration
Foundation patterns for using
[sem](https://github.com/Ataraxy-Labs/sem) semantic
diffs in night-market skills.
## When To Use
Consult this skill when building or modifying skills that
consume git diff output. It provides the detection,
installation, and fallback patterns.
## When NOT To Use
- Direct sem CLI usage (just run `sem diff` yourself)
- Skills that don't consume diff output
## Detection Pattern
Check sem availability once per session:
```bash
# Detection (cache per session)
_sem_check() {
local cache="${CLAUDE_CODE_TMPDIR:-/tmp}/sem-available"
if [ -f "$cache" ]; then
cat "$cache"
return
fi
if command -v sem &>/dev/null; then
echo "1" | tee "$cache"
else
echo "0" | tee "$cache"
fi
}
```
When `_sem_check` returns `0`, offer installation.
See `modules/detection.md` for install-on-first-use
logic and platform-specific commands.
## Semantic Diff Pattern
Primary path (sem available):
```bash
sem diff --format json <baseline>
```
Fallback path (sem unavailable):
```bash
git diff --name-only --diff-filter=A <baseline>
git diff --name-only --diff-filter=M <baseline>
git diff --name-only --diff-filter=D <baseline>

How to install
mdr add athola/claude-night-market/sem-integration@sha256:7d83b75c6564039aThe line at the top of this page pins the label git:20261028.bb10c61, 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.
