config-sync is a skill for Claude Code, Codex from laurigates/claude-plugins. It costs 28 tokens per session (3,097 once invoked), scanned A, original, MIT.

A tool for comparing development workflows and configuration files across multiple repositories, then copying selected improvements between them.

In plain words

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

config-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 today.

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.

The opening of the file, as written. The whole thing — 359 lines — stays where its author put it; the contents beside it link to each section on GitHub.

/configure:config-sync

Extract, compare, and propagate tooling config improvements across FVH repos.

When to Use This Skill

Use this skill when... Use another approach when...
Comparing a workflow/config across all FVH repos Configuring a single repo's workflow from scratch — use /configure:workflows
Propagating an improvement from one repo to many Debugging a failing CI run — use github-actions-inspection
Identifying which repos have outdated configs Creating a reusable workflow — use /configure:reusable-workflows
Extracting novel patterns from a repo to share Checking a single repo's compliance — use /configure:status

Context

  • Workspace root: /Users/lgates/repos/ForumViriumHelsinki
  • Repos: !fd -t d -d 1 . /Users/lgates/repos/ForumViriumHelsinki --exclude .git --exclude node_modules
  • Current directory: !pwd

Parameters

Parse mode and options from command arguments:

Modes

  1. extract [repo-name] — Identify improvements in a source repo
  2. diff <file-pattern> — Compare a specific config across all repos
  3. apply <file-pattern> [--from repo] [--to repo1,repo2,...|--all] — Propagate config to targets

Options

  • --from <repo> — Source repo for apply mode (default: best version detected)
  • --to <repo1,repo2,...> — Target repos (comma-separated)
  • --all — Target all repos that have the file
  • --dry-run — Show what would change without creating branches/PRs (default behavior)
  • --confirm — Actually create branches and PRs

Config Categories

Files tracked for cross-repo sync, organized by sync strategy:

Tier 1: Wholesale (100% identical across repos)

Copy verbatim — no repo-specific variations expected.

File Pattern Description
.github/workflows/claude.yml Claude Code workflow
renovate.json Renovate dependency updates

Tier 2: Parameterized (shared core with known variation points)

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.
