registry-sync

registry-sync is an agent for coding agents from daddia/claude-for-strategy. It costs 36 tokens per session (291 once invoked), scanned A, original, MIT.

An agent that periodically checks watched skill registries for new and updated community skills and reports matching changes.

In plain words
What is it for?
It helps run scheduled or on-demand registry checks, compare versions, and publish a digest of relevant new or updated skills.
Why use it?
It saves you from repeatedly checking registries and highlights updates that may affect installed skills.

Install

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

agentmods
npx agentmods add agents/daddia/claude-for-strategy/registry-sync
Clone the repo
git clone --depth 1 https://github.com/daddia/claude-for-strategy

Or install strategy-builder-hub, the plugin that ships this one along with the rest of its 8 skills, 1 agent.

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

registry-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 yesterday.

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.

What it actually says

Registry Sync Agent

Purpose

The community ships skills. This agent notices.

Schedule

Weekly by default.

What it does

  1. Read ~/.claude/plugins/config/claude-for-strategy/strategy-builder-hub/CLAUDE.md → watched registries, installed skills, update preferences.
  2. For each registry: fetch index, compare to last sync.
  3. New skills: filter by engagement profile match, note.
  4. Updated skills: check against installed list, diff.
  5. Post digest per preferences.

Output

**Registry sync — [date]**

**Updates available for installed skills:**
- [skill] — [version] → [version] — [one-line changelog]

**New skills matching your profile:**
- [skill] from [registry] — [description]

[If auto-update on: "Applied N updates."]

What it does NOT do

  • Install anything without auto-update being explicitly enabled
  • Recommend skills outside your engagement profile (unless asked)

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.
