What is personal-agent?

A plugin containing a public catalogue from yesterday for Claude Code and Cursor, two tools that use coding agents.

Use it to refer to that dated plugin catalogue when working with Claude Code or Cursor.

It can provide a snapshot of add-ons available in those catalogues, but the input does not describe any other function.

personal-agent — Plugin for Claude Code by Yesterday-AI/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.

Clone the repo

git clone --depth 1 https://github.com/Yesterday-AI/skills

Made for: Claude Code.

Security

Grade A, and why

personal-agent 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 1mo 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.

Origin

This is a copy

100% identical to office — 18 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 installs

The manifest is a name and a version. 14 skills travel with it, and installing the plugin installs all of them — 741 tokens a session between them. Each is measured on its own page, and each can be installed alone.

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.
