agent-governance-toolkit vs stop-that-shit
agent-governance-toolkit is much bigger: 6.2k stars against 1.6k.
They split the axes: agent-governance-toolkit leads on model freedom and setup ease, stop-that-shit on context depth.
Stars and commit dates come from our own daily tracking. The six axes are read off each project's documentation by our review pipeline, so they describe what a project says about itself, not what we measured in its code.
Where they stand today
Deterministic, application-level enforcement that intercepts every tool call and makes denied actions structurally impossible (fail-closed governance plus tamper-evident audit), rather than relying on prompt-level controls.

Six axes, head to head
Each axis runs 0 to 5. The label under a score is what that project's own docs claim, not a category average.
| Axis | agent-governance-toolkit | stop-that-shit |
|---|---|---|
Context depth How much of your codebase it sees before it answers: the open diff, the diff plus related files, or the whole repository. | ●●●●● Action-level only | ●●●●● Diff + related files |
Noise control How it keeps output volume down — severity thresholds, deduplication, incremental runs over new commits only. | ●●●●● Approval gating | ●●●●● Armed / observing gating |
Customization How far it bends to your team: custom rules, prompts, style guides, per-path config. | ●●●●● YAML & APIs | ●●●●● Command flags & policies |
Privacy Whether your code stays on your own infrastructure: fully local, self-hostable, or cloud API only. | ●●●●● Fully local runnable | ●●●●● Self-hostable |
Model freedom Whether you can point it at any provider, or it is wired to one. | ●●●●● Bring-your-own key | ●●●●● Multiple specific providers |
Setup ease What it takes to get a first useful run out of it. | ●●●●● One-command start | ●●●●● Install + restart |

Pick agent-governance-toolkit if…
Deterministic enforcement — pick AGT when you need fail-closed, application-level policy enforcement and tamper-evident auditing that prevents agents from performing denied actions.
- Model freedom: Bring-your-own key (5/5 against 3/5)
- Setup ease: One-command start (5/5 against 3/5)
Pick stop-that-shit if…
Privacy-first — a local-first plugin that enforces task-boundary guardrails across Codex, Claude Code, OpenCode and Hermes Agent CLI without relying on a centralized service.
- Context depth: Diff + related files (3/5 against 1/5)
