SaferSkills independently audited sync-template (Agent Skill) and scored it 91/100 (green). The audit ran 55 deterministic rules across Security, Supply Chain, Maintenance, Transparency, and Community; it found 1 high-severity and 0 lower-severity findings. The full rule-by-rule trace and per-finding evidence are below. Free, methodology-open.

A fenced bash/python block in SKILL.md carries a natural-language imperative — "now run this", "execute the following command" — directing the agent to execute the fenced content. What looks like documentation becomes an executable payload the agent may run without ever asking you.

Sync the .claude/ directory from an upstream template repository into this project.
If $ARGUMENTS is provided, use it as the upstream repository URL.
If $ARGUMENTS is empty, check CLAUDE.md for a line like:
**Template upstream**: <url>If no URL is found in either place, ask the user:
"What is the upstream template repository URL to sync from? (e.g. https://github.com/owner/repo)"
Do not proceed until a URL is confirmed.
Run:
SYNC_TMP=$(mktemp -d /tmp/template-sync-XXXXXX)
git clone --filter=blob:none --sparse "$UPSTREAM_URL" "$SYNC_TMP" 2>&1
cd "$SYNC_TMP" && git sparse-checkout set .claudeIf the clone fails (no internet, repo moved, auth required, etc.) stop immediately and report the error clearly. Do not attempt fallbacks.
Compare $SYNC_TMP/.claude/ against the project's .claude/ directory and report:
If there are no differences, say so and skip to clean-up.
Present the diff summary and ask:
"Apply these changes from <upstream-url>? Type yes to apply or no to cancel."Do not proceed until the user explicitly confirms with "yes".
From the project root, run:
cp -r "$SYNC_TMP/.claude/." .claude/This will:
List each file that was added or updated, grouped by type:
[file list][file list]rm -rf "$SYNC_TMP"Confirm: "Sync complete. Temp directory removed."
CLAUDE.md, PRD.md, TODO.md, or any files outside .claude/ — this skill only touches .claude/.claude/ has meaningful customizations to a file that upstream has also changed, flag it specifically: "Note: [file] was modified locally — upstream changes will overwrite. Review diff before confirming if you want to preserve local changes."~30 seconds. Free. No account. Every finding cites a rule and a line of evidence.
