pemr: Skill for Claude Code

.claude/skills/pemr-upstream-sync/SKILL.md

pemr-upstream-sync is a skill for Claude Code from meridun/pemr. It costs 84 tokens per session (2,383 once invoked), scanned A, original, no licence file.

A set of agent instructions for comparing and synchronising shared configuration between a project repository and a model-repo upstream hub. A repository is a project's version-controlled file store, and upstream is the source repository changes can come from.

In plain words
What is it for?
Use it to sync shared repository components, move an improvement upstream, migrate the latest component, or audit the shared setup.
Why use it?
It helps avoid manually comparing and copying shared instructions, skills, hooks, agents, prompts, and scripts between repositories. It can also keep a selected upstream version fixed, or pinned.

This is meridun/pemr's own configuration. It tells Claude Code how to work on pemr itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything pemr configures →

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

pemr-upstream-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 17d 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.

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.
