agent-plugins

A plugin marketplace listing for eight coding-agent plugins, including tools for Zig, TDD, code review, and paired development. A plugin is an add-on that gives an agent extra instructions or workflows.

In plain words
What is it for?
It catalogs plugins such as zig-claude-kit, tiger-style, tdd-pipeline, and cross-review, along with their package locations and marketplace metadata.
Why use it?
Keeping related plugins in one marketplace file makes them easier to discover and install. The supplied listing also records each plugin's source and description.

Plugin for Claude Code

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.

Grade A, and why

agent-plugins 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 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.
