sync

A repository-synchronization skill that pulls the latest guidelines from configured repositories, which are shared code or documentation stores.

In plain words
What is it for?
Use it to update read-only guideline mirrors and rebase write-enabled repositories while retaining local publishing commits.
Why use it?
It keeps local guidance aligned with its sources and records synchronization activity. It also preserves unpublished changes in repositories where publishing is allowed.

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 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 2d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/sync.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Origin

This is a copy

97% identical to evolve-lite:sync — 6 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

What it actually says

Sync Repos

Overview

Pull the latest guidelines from every repo in evolve.config.yaml repos: list — both scope: read (subscribe-only) and scope: write (publish targets). Write-scope repos use a rebase strategy so any unpushed local publish commits are preserved.

Workflow

Step 1: Run sync script

python3 ${CLAUDE_PLUGIN_ROOT}/skills/evolve-lite/sync/scripts/sync.py

Step 2: Display summary

Show the script output to the user. If there are no repos configured, tell them they can add one with /evolve-lite:subscribe. If there are no changes, explain that everything is already up to date.

Notes

  • Read-scope repos are mirrored exactly via git fetch + git reset --hard
  • Write-scope repos use git fetch + git rebase so unpushed local publish commits are preserved
  • Sync results are logged to .evolve/audit.log
Files

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.

Changes

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.
