hames

hames is a plugin for Claude Code from baek-labs/hames. Its manifest loads nothing; the 4 skills, 3 hooks it bundles cost 68 tokens per session together, scanned A, original, MIT.

A workspace-first harness for approved, evidence-backed agent work. It organizes task contracts, approvals, execution, verification, and review around the project workspace.

In plain words
What is it for?
Use it to manage controlled agent tasks that need contracts, evidence collection, verification, and human review.
Why use it?
It gives agent changes explicit boundaries and a record of what was approved and verified. This helps people inspect work before accepting it.

Security

Grade A, and why

hames 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 today.

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. 4 skills, 3 hooks travel with it, and installing the plugin installs all of them — 68 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.
