constitution

constitution is a plugin for Claude Code from thlandgraf/cc-marketplace. Its manifest loads nothing; the 1 skill, 3 commands it bundles cost 76 tokens per session together, scanned A, original, no licence file.

A project constitution manager for storing rules, recommended practices, design patterns, and safety limits for coding agents.

In plain words
What is it for?
It is for managing the files that define how an agent should work within a project.
Why use it?
It gives coding agents a shared set of project expectations to follow instead of relying only on informal instructions.

Security

Grade A, and why

constitution 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 3d 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. 1 skill, 3 commands travel with it, and installing the plugin installs all of them — 76 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.
