Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

What it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00083 | $0.01897 |
| Opus 5 | $0.00042 | $0.00949 |
| Sonnet 5 | $0.00017 | $0.00379 |
| Haiku 4.5 | $0.00008 | $0.00190 |
Grade A, and why
homerail-install-ops scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Makes network callslowCapability
Not a fault in itself. Listed so you know the mod talks to something, and to what.
Do not supplement it with `ps`, `lsof`, `curl /health`, or source reading unless How it starts
The opening of the file, as written. The whole thing — 201 lines — stays where its author put it; the contents beside it link to each section on GitHub.
HomeRail Install Ops
Before acting, apply homerail-shared rules. This pre-publication flow uses a local source checkout or local Git clone, not npm publication.
Local Skill Install
Install HomeRail skills by linking the checkout's skills/homerail-*
directories into the target agent skill directory. Prefer symlinks over copies
so skill updates follow git pull.
If the source tree is already present, use skills/README.md as the source of
truth for Codex and Claude Code install targets. On macOS/Linux:
repo=/path/to/HomeRail
for root in "${CODEX_HOME:-$HOME/.codex}/skills" "$HOME/.claude/skills"; do
mkdir -p "$root"
for skill in "$repo"/skills/homerail-*; do
[ -d "$skill" ] || continue
name="$(basename "$skill")"
dst="$root/$name"
if [ -L "$dst" ]; then
rm "$dst"
elif [ -e "$dst" ]; then
echo "Refusing to replace existing non-symlink skill: $dst" >&2
continue
fi
ln -s "$skill" "$dst"
done
done
If the user gives a local Git address, clone it first, then install links from the checkout:
git clone <local-homerail-git-url> HomeRail
cd HomeRail
On Windows, use PowerShell directory symlinks when Developer Mode or
Administrator permissions allow them. If symlinks are blocked, use a junction
as the local fallback; repeat the junction for every skills/homerail-*
directory that should be installed:
cmd /c mklink /J "%USERPROFILE%\.claude\skills\homerail-install-ops" "C:\path\to\HomeRail\skills\homerail-install-ops"
After installing or updating skills, ask the user to restart the AI agent session if their agent host only loads skills on startup.
After restart, route user requests to the root skills this way:
- Use
homerail-install-opsfor first install, update, service startup, provider configuration, and smoke verification. Codex invocation:$homerail-install-ops; Claude Code invocation:/homerail-install-ops. - Use
homerail-dag-opsfor running DAGs, monitoring runs, checking handoffs, and writing DAG templates. - Use
homerail-dag-patternsfor selecting, composing, instantiating, and validating built-in DAG design patterns. - Use
homerail-clifor command syntax, flags, and evidence commands. - Use
homerail-sharedas background rules for all HomeRail operations.
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

homerail-install-ops is a skill published in the GitHub repository xiaotianfotos/homerail (951 stars, last pushed today), licensed MIT. It adds 83 tokens to every session and 1,897 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
