agent-toolkit-agents

agent-toolkit-agents is a plugin for Claude Code from ulises-jeremias/agent-toolkit. Its manifest loads nothing; the 18 agents it bundles cost 1,029 tokens per session together, scanned A, original, MIT.

A collection of 18 AI agent roles for different software tasks, including planning, design, implementation, review, testing, security, research, and data work. TDD, or test-driven development, is also represented by a specialist role.

In plain words
What is it for?
Use the roles to plan projects, design systems, write and review code, investigate security, run end-to-end tests, resolve build errors, and guide test-driven development.
Why use it?
It separates work into defined roles so an agent can approach a project from the perspective needed for each task.

Security

Grade A, and why

agent-toolkit-agents 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 4d 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.
