A plugin that provides a structured, seven-stage development process for coding agents. It includes orchestration, planning, verification, testing, backlog work, and a way to involve a person when decisions need review.

Use it to coordinate feature work, groom and plan backlog items, run verification and testing stages, and compose the process with language-specific tools.

It gives agent-led development a repeatable workflow and keeps process artifacts and human review points organised.

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/Jamie-BitFlight/claude_skills

Made for: Claude Code.

Security

Grade A, and why

dh 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 6d 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 it installs

The manifest is a name and a version. 70 skills, 29 agents travel with it, and installing the plugin installs all of them — 7,272 tokens a session between them. Each is measured on its own page, and each can be installed alone.

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.
