sync-repos

sync-repos is a cursor rule for Cursor from thatrebeccarae/claude-marketing. It costs 38 tokens per session (3,587 once invoked), scanned A, original, MIT.

A repository-sync rule manages a private development repository and its public counterpart, checking whether their contents match.

In plain words
What is it for?
It helps compare repositories, run a synchronization script, set up a new repository pair, and validate the result before publication.
Why use it?
It helps catch changes that have not reached the public repository and checks that private information, personal data, or secrets are not exposed.

Cursor rule for Cursor

Written for Cursor: a Cursor rule (.mdc). Also seen: mentions Claude Code.

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is bash scripts/sync-public.sh.

Good fit It helps compare repositories, run a synchronization script, set up a new repository pair, and validate the result before publication.

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.

Token cost

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.

Security

Grade A, and why

sync-repos scanned grade A with 0 findings 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 8d 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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Sync Repos

Manage public/private repository pairs. Verify parity between a dev (private) repo and its public counterpart, detect drift, run sync scripts, validate results, and ensure no PII or secrets leak to the public side.

When to Use

  • Before pushing a public repo — verify the sync is clean and current
  • After major dev work — check whether the public repo has drifted behind
  • On a periodic cadence — weekly or before releases, catch unsynced changes early
  • When setting up a new public/private repo pair for the first time

Usage

  • /sync-repos check [dev-path] [public-path] — Compare repos and report drift
  • /sync-repos sync [dev-path] [public-path] — Run sync script and validate
  • /sync-repos setup [dev-path] [public-path] — Create initial sync-public.sh and config

If paths are omitted, prompt the user for them. Look for .syncignore or scripts/sync-public.conf in the dev repo to auto-detect the pair.

Procedure

Check Mode

  1. Validate paths. Confirm both paths exist and contain .git/ directories. Abort with a clear message if either is not a git repo.

  2. Detect sync script. Look for scripts/sync-public.sh, scripts/sync-public.conf, or .syncignore in the dev repo. Report whether a sync mechanism exists.

  3. Compare file lists. Generate sorted file lists for both repos (excluding .git/, node_modules/, dist/). Categorize differences:

    • Expected exclusions — files matching known exclusion patterns (see Common Exclusion Patterns below) or listed in .syncignore / sync-public.conf
    • Unexpected drift — files present in dev but missing from public that are NOT in any exclusion list
    • Diverged files — files present in both repos but with different content (compare via sha256sum or git hash-object)
    • Public-only files — files in public but not in dev (legitimate: README, CONTRIBUTING, LICENSE, .github/)
  4. Check last sync timestamp. If scripts/sync-public.sh exists, check its last execution time via the most recent commit in the public repo that matches a sync pattern. Compare against the latest commit in the dev repo.

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.
